So /B/ they just discovered that next to the star that is closest to our solar system is a habitable planet.It is 4 lightyears away.How does this make you feel?
I'm not saying space travel isn't possible, but theoretically we could build a Generations ship. Make it completely self sustainable with THOUSANDS of different protocols in order to make sure that the mission goes well. Multiple ion thrusters on the back of the ship allowing us to reach 5% the speed of light. And somehow if we actually manage to get ALL of that together we would still run into the issue of
>Blocking out harmful UV rays so everyone on board doesn't get cancer
>A star cruiser with enough rations and material in order to get to said planet.
> a vast number of mechanics to fix the ships EVERY NEED
> if they manage to get to the planet they are fucked if it's not actually habitable.
>It would take a few hundred years going 5% the speed of light.
>Possible chance of inbreeding
We got this guy's. The world won't shit itself before we inhabit another planet.
you dont understand how time dilation works do you?
we already use shielding to block rays and radiation on our current spacecraft with pretty good effectiveness
due to time dilation it honestly wouldnt require tons of supplies, if they can make it to mars which they're currently planning to do, they can make it even further out
you dont need a "vast number of mechanics" stop being silly
cant argue with number 4
it might take "hundreds of years" but due to time dilation, the people on board the spacecraft would only age a fraction of that
inbreeding would not be a real risk once again due to time dilation
also the faster the craft goes, the more time dilates, the only real issue is slowing the craft down but that can be done using the gravity of the destination planet
its actually all very possible. and its not as science fiction as you might think
Exterminate xenos in the name of God Emperor.
Nooot to mention the amount of doctors on board to make sure no none gets sick.
A platoon of people to hold order in the star cruiser.
Maybe 5-6 Dozen vertical artificial farms.
Constant recyclable water
Living quarters for x amount of people on the ship. (This includes children)
actual experienced travel time would be even less than 80 years because of time dilation
a round trip would be out of the question though, at least if the people intended to ever see the same people again
The Alpha Centauri system has no planets that are known to be habitable to humans. All we know is that we just found out that Proxima Centauri has a planet that is within the possible habitation zone for a planet.
All that means is that if there is water there it could be liquid if the atmosphere is correct. We also don't know anything about the contents of the atmosphere or the planets ability to reflect radiation.
It is not known to be habitable by any definition.
People are talking about how close it is but shit we can't even get a probe there in our lifetimes yet. What makes this interesting is that when we are ready for insterstellar travel/probes, this system will be the first simply because it is the closest to us.
Even considering that our radio waves have been travelling through space for the last 80 yrs at the speed of light, there has been plenty of time for an advanced species to receive our radio signals and maybe respond back.
tl'dr: still don't have the tech to reach it, probably no intelligent life as we know it, even if it can support life.
>if they can make it to mars which they're currently planning to do, they can make it even further out
You fucking moron, mars is our next door neighbour.
Look, think of it like this.
The sun is 90,000,000 miles away and it takes light about 8 minutes to reach us from the sun.
So in effect, the sun is 8 light minutes away.
This new planet is 4 light YEARS away.
Can you even begin to comprehend that distance?
4 light years is 2,102,400 light minutes.
The new planet is 262,800 times as far away as the sun.
Basically, if you scaled down teh distance from the Earth to the sun to 1cm, this new planet would be 1.63 MILES away.
Just think about that.
the distance between the Earth and the sun is about as wide as your fingernail and this new planet is 1.6 miles away.
Herp derp they don't use the same technology as us, they must not be an intelligent race
Not to mention the fact that even if they do use radio waves to communicate, how the fuck would they be able to understand us
There is exactly no indication that there is life of any kind on that planet. The only interesting thing is it sits on the habitable zone of the star.
We do have the tech to reach it. The reality of the situation is space travel between habitable planets will always be a slow process.
Even if the EM drive turns out to be the holy grail people are hoping it is, it is barely any better than an Ion drive.
The funny thing is that people keep thinking you need a planet to go to instead of the ship being the goal and planets just being big piles of resources.
It sounds like you don't understand highschool physics. Radio waves aren't parallel to any other wireless communication. They are vastly superior and more reliable than light signals and we know they travel through space well (although slowly). There may be better technology that we simply haven't discovered but radio waves are significant and any species that has evolved to the technological level to discover them will understand their significance for their own uses and if and when they advanced beyond its use they would still understand that radio waves would likely be how a species first reaches out from its planet and monitor that traffic.
Also you don't even need to understand what is being said. The fact that you can see a deliberate message from a different planet tells you a great deal about them.
Self sealing bulkheads. Segments of the ship automatically close to maintain atmosphere.
The physical danger is not really any different here on earth. Also the analogue here is some fags are poisoning the planet because its the cheapest way to deal with their garbage. Where is your escape?
What if we discover the planet is habitable, but has INDIGENOUS LIFEFORMS?
>will understand their significance for their own uses and if and when they advanced beyond its use they would still understand that radio waves would likely be how a species first reaches out from its planet and monitor that traffic.
I hope for the same reason they will still recognize us as life, even when they are billions of years more advanced than us, and still find us interesting.
>speaking of doctors
PLEASE STATE THE NATURE OF THE MEDICAL EMERGENCY.
Google. All major news networks have released the story.
The story is that a planet has been newly discovered orbiting proxima centauri abd ut sits in the habitable zone.
Nothing else is known. We don't know if there is water, we don't know if there is oxygen, we don't know if there is an atmosphere, we don't know if there is a magnetosphere.
Saying it is habitable at this point is completely false.
I'm proud that we have the technology to understand and observe this astronomical discovery but im also a little worried about what kind of careless destruction this could bring to the Earth. And there could always have been a miscalculation and this isnt actually habitable. One of the main rules of science is to remain skeptic.
IMO what we really need is:
>the ability to construct extremely large rockets
>a rocket that doesn't use stages, but instead continuously sheds weight for maximum efficiency
Unfortunately I suck at calculus so I can't figure out how much mass you'd need for a given speed.
So that's where these fuckers are coming from.
What year do you think this is Jerry? Ion drives don't nee cumbersome solid fuel tanks and we are literally trying to figure out how our miracle EM drive, that uses electricity for fuel, works.
Building a interstellar ship in space or on the moon removes most of the need for solid rockets.
an ion drive works by applying a charge to a fuel source, yes a fuel source, but non-combustible and its attactted to its opposite charge, the charge cancles and particles are flung out in a direction.
since the particles go in one direction they push the space craft in the opposite direction.
you can build one yourself out of some balsa wood, aluminum foil, and a neon sign transformer. its fuel sorce is atmosphere and can generate enough thrust to actually lift it off the ground, not with the transformer mind you.
A big tank of xenon isn't going to take up the weight or room of a solid rocket. And thats if you wanted to still use xenon.
Also grats on the cherry picking. What about the EM drive. Sure its unreliable because we don't understand why its producing thrust but it runs on energy which you can collect during the voyage.
Rockets have no place in interstellar travel. Their only purpose is to exit the atmosphere.
Bored and tired. We know nothing about it other than where it is and that it is in the "habitable range" and already people are shitting themselves saying it is habitable and likely has life.
Humans will never ever ever ever reach another planet in this domain, Mars maybe, but they won't make it back. 4 light years lololol. One light year is like 6 trillion miles or some shit. Good luck retards. We have a perfectly habitable planet right here that has been here for over 4 billion years, we will be wiped out and the next life-form will be wiped out, and the next, and the next, and the next. Humans sure are full of themselves.
there are many theories
gravity is a theory, yet here we are stuck to this spinning ball and it works just fine
my personal favorite is the lines of force are a representation of 4th dimensional space being inflicted on our 3rd dimensional plane when ferrous materials molecular poles align.
we just don;t have the technology to test these theories and probably never will for a couple centuries.
It wouldn't surprise me if a whole Star Trek or Star Wars thing goes on there in outer space and everyone just doesn't drag us into this because we are the most retarded species in the Universe. I mean a Gigantic majority of roughly 7 billion people allows a tiny minority of not even 500 million people to control them although they just use this power so they can fill up their own purse and we let them do that for whatever reason
And none of it has been proven. So you don't know how it works.
>molecular poles align
Nigger you must be joking. Molecular poles is a debunked theory. Magnetic field orientation is determined by electron spin.
yes but calling a technology unreliable because we don't understand it is like asking kids why they like apple jacks when they don't taste like apples.
magnets are in use everywhere
Any planet that would be habitable for humans, it would have to take many generations to adapt to the planet. The human body was made on earth for earth. Besides, the people that would be traveling interstellar would have many problems to the organs/blood pressure due to no gravity
fucking weird trying to comprehend the relatively short distance involved.
Less than 80 and even less than that for the crew because of minor time dilation. EM drive could also in theory go faster than the Ion drive which would cut the trip time down even further.
Son. Please. The interstellar vessel would only have to have constant acceleration of 9.2m/s^2 to mimic earths gravity. You could also accelerate slightly faster with no ill effects.
Also, it is impossible to adapt to a planet that is lethal to you. You can't simply evolve to not need oxygen or water.
Life evolved on this planet for the conditions of this planet. You're going to be hard pressed to find a planet we're going to easily adapt to even of it is hosting other life. We belong on the earth.
Read somewhere that they -might- have figured the EM drive out.
Turns out the actual thrust production is radiant energy, photons in the microwave frequencies, that have had their charge neutralized. Being charge neutral makes them nearly impossible to detect, so proof is a ways off.
the bigger problem is packing enough fuel to accelerate constantly for ~100 years
even LFTRs (assuming they work) require more than half the vehicle's mass at LEO (or even HEO) to be fuel
An experiment was done using briefcase-sized cesium clocks on an airliner. The dilation was in the billionths of a second (Maybe less), but it -was- measurable. And it was at the speeds typical of a commercial airliner on a trans atlantic flight
Dudes, we couldn't live there if the gravity was stronger than what earth has. its 1.3 times the size of earth so it could have stronger gravity.
that means every human who tried to live there would have all their internal organs fall out their ass
WHAT IS THE EMDRIVE THAT PEOPLE CAN LITERALLY NOT STOP TALKING ABOUT.
No fuel. Constant acceleration in a vacuum.
Also stop saying ~100. Less than 80 years is not ~100 for a human.
Here comes the Shitposters. Me 001 Shitposter. If you Faggots have to attain the speed of light, and then maintain it for 4 yrs. just to get there, how fucking stupid are you? What you gonna eat for them 4 yrs. Put a micky D's on your craft and go through the drive through three times a day. God Dam Faggots.
I should have said noticeable effect
5%C over a century far from any significant mass would give the passengers ~1day of gained time
and the results of the airline experiments are believed to be due to being further from the bulk of Earth's mass than speed
>WHAT IS THE EMDRIVE THAT PEOPLE CAN LITERALLY NOT STOP TALKING ABOUT.
what is theoretical technology that has not had a proof of concept test
what we can build right now will make the trip ~100 years
show me a proof of concept protype and I'll drop that down to your 80 year estimate
I remember reading a sci-fi story many years ago about this very problem. I think Asimov was the author.
What was done was an AI "device" was sent to a hospitable planet with frozen embryos, the colonists. It would then thaw the embryos, and bring them to maturity. Once born, this device was mother, teacher, protector and home.
Not the kind of colonization we usually think of, but it does spread humanity.
There is a lot wrong with this.
Firstly, we can live in a slightly higher gravity environment just fine. 1.3 times earths gravity is perfectly livable. A 100 lbs person would feel like they were 130 lbs. That is hardly organs falling out your ass territory.
Secondly, 1.3 times size does not mean 1.3 times gravity. It could easily have less mass than earth and even be lower gravity.
Do they not cover this stuff in high school where you live? Size is volume and is not directly related to mass.
>what is theoretical technology
No, it is very real technology that has been proven to work in practice. We simply don't know why it produces as much thrust as it does.
Also, do the math again. 80 years comes from the concept of constant acceleration of 9.2 m/s^2 to mimic earths gravity. 100 years is a disgustingly inaccurate time frame.
would be news to me
pls link story
and either way
it would probably take 20 years of development to get EM to a point that it would be trusted enough to transport people
so 100 years in transit or 100 years combined wait time and transit is 100 years and ~40 years longer than I can reasonably expect to live
I would shudder to think that canisters full of alien DNA are on their way here.
You were still wrong about organs falling out the ass and not being able to live in a gravity well stronger than earths.
>COULD COULD COULD
Could anything so fucking what. The gravity COULD be identical and it COULD have rivers of chocolate milk and it COULD have mountains that look like giant fake tits.
This. It's impossible. Our only chance would be surviving until we collide with Andromeda and hoping we end up with some new planets or stars being significantly closer. We're fucked. We know enough to know our only chance might be blasting some sperm and eggs out into space to be raised by robots.
Calm your fucking tits, asshole.
He had a valid question and though he is misinformed, it is a completely genuine question.
Stars undergo nuclear reaction burning hydrogen in their cores while planets don't.
They have a completely different way of forming too.
funny how everyone always assumes alien life will be advanced, what if they are black?
dude, 1.3 times gravity like what was mentioned would have negative affects for prolonged periods. sure if a person put on 30% body weight chances are they could still move around, but 30% more strain on connective tissues securing our organs in place would eventually tear them. i don't blame you for not knowing that, they don't teach that in high school.
it very well could have twice earths gravity.
there is so much we don't know, though with some math we could figure it out once we get more numbers than its year is 11.2 days.
now i'm waiting for some tard to mention all we would have to do is invert ourselves for half the day and we'll be fine
Unlikely on a ship that uses sensitive instruments. Hydro/aqua is by far the safer bet.
You don't you build in on the moon the farthest surface available away from the center of earths gravity well and no atmospheric friction.
>BUT THERES NO MOONBASE!
You think we would send a generational ship to Proxima b to start a colony and not have the technology to build a manufactory for ship launch on the moon?
>cold fusion meme
go troll elsewhere, chum. The sad fact of the matter is that we're actually making pretty solid progress on antimatter and I wouldnt be surprised if we had a crude antimatter drive a hundred years from now, but no, you had to go full retard and trot out the cold fusion meme like a moron
They remain stable for trillions of years. However, they are more inconsistent than our sun, sunspots can drop luminosity significantly more and flares can be even more intense
you get 40 1 acre ships into orbit and assemble them there. Or if you want to get reeeeeally advanced, you dont even bother building the ship on earth but build a shipyard in the asteroid belt and mine what you need there. We're a good 300 years off that though, if we start working on it tomorrow.
>We're actually less than 25 years away from discovering cold fusion
Yes and that is a date you can bank on.
>negative affects for prolonged periods
1.3 times gravity means relatively 1.3 times weight. No astronaut have ever been over weight which means 1.3 times body weight would at worse be in the lower half of over weight. You could drop enough weight to still be in the healthy range for your height and not endure any short term or long term effects of the increased gravity.
>it very well could have twice earths gravity.
Actually all indications points to earth like or lower
>there is so much we don't know
Correct, we know almost nothing and there is no way to accurately measure gravity in this scenario.
Correct me if i'm wrong, but it's MIGHT be habitable, right?
4 light years is totally reachable too, just whip out those Project Orion blueprints.
I'm kinda reluctant to suggest that we start interstellar travel though. The last thing we want is to attract attention and draw RKKVs our way.
According to the criteria used to qualify the newly found planet, Venus and Mars are also potentially habitable.
I don't know you but I certainly wouldn't want to live there. Venus is full of feminists and on Mars the floor is covered in caramel.
Yes but there is no information so far that indicates that it is.
The thing that is confusing people is that it is in the habitable zone of proxima centauri which ONLY means that if there is water there it would be liquid.
>We're a good 300 years off that though, if we start working on it tomorrow.
I would think we could do it faster than that. We went from first flight to moon landing in under a hundred years and we already have the tech to colonize Mars, all we lack is motivation.
What we need is a "When Worlds Collide" kind of situation to kick us in the ass to get moving.
Let's all b/ on the moon
Lets' all b/ in our space suits

Let's all arrive at Mcdestination and have a hell of an alien orgy . Why don't we..
ahaha Avoid the point with linguistic analysis.
What next? Grammar and spelling?
Less then 25 years is a crock of shit that idiots believe and is told to them by people who like to fool idiots.
Read some articles about it. It is in proxima centauri's gravity well instead of α/β well. This is an indicator that its gravity is lower than we would expect from it's size.
It is all basically supposition though because you can't accurately measure the mass of a planet if there isn't a known gravitational variable to monitor.
yeah we got to the moon 50 years ago and did fuck all since. We hit the boundary of what we're capable of with our current level of technology in the 70s, man. We've made progress since then, but nothing that's made the leap to allow us to do anything major. We'll need self sustaining and safe fusion that you can just set going and forget about to even have a shot at getting humans out there in the solar system. We arent going to get a full scale fusion reactor that provides more power than it takes for another 20 years with ITER, and that's if everything goes to plan on that. Then you're taking 40 years of rolling that tech out across the planet, then if you're really really lucky, 40 years before they start making safe enough ones to strap on a ship. Then 50 years of sending them on set up mission on and around the moon, then 50 years of waystation laying.
We all have this idea that because we went from flying to flying to the moon quickly we can just fly to mars, but the truth is that it cant really be done, not for a long time yet.

umm, yes we can figure out gravity
the planets orbit will tell us the gravity once we know the mass of the star. its proximity to a known mass as well as speed (we know is 11.2 days round trip). we can figure that shit out.
how do you think we know what the other planets gravity is like in our own solar system? it wasn't from sending "probes".
you do realize that all your organs are held in place with connective tissues and its not like tetris were they all support one another?
even on earth connective tissues fail and organs drop and it requires surgery to stitch them back in place. shit happens to elderly people all the time. a 30% increase would just means it happens more often and at younger ages thus organs falling out your ass.
If you have a powerful enough laser and know where to point it you can hit the same retro-reflector that they used in the Mythbusters episode on this very subject.
Hell, if you have a big enough telescope you can SEE the fucking thing
1) this system wasn't "just discovered". We've been in contact with the inhabitants for millennia
2) they have been here many times.
3) the star will supernova in the near future. it is already a red dwarf.
4) they want to move the entire population to Earth to avoid extinction.
5) nothing we can do to stop them.
6) many, but not all, world leaders know this.
don't you know about the Nash equilibrium you fucking pleb. Competition WAS the primary driving force behind all advancement. Sharing a common goal can be a greater motivator even when not directly working together as long as the initial competitive strategy of both sides is altered to not be in direct competition.
Never liked that idea, too fucking crude. Gotta be a better way to utilize atomic energy for propulsion in a vacuum than dropping inefficient, radiologicaly dirty-ass bombs behind you.
Humankind is incapable of of reaching that planet before destroying itself. Incapable of working together internationally to take on such a daunting task scientifically... Instead global warming will kill us all.
The amount of rocket fuel it would take to put that much material into orbit would not only bankrupt the entire planet, but destroy the environment. It's like watching children discuss things they know nothing about.
That doesn't make them wrong on this. They went to an observatory for the laser bounce test.
Point is, this is pretty much settled and the only people still screaming the moon landing was faked are the kind of people that put their fingers in their ears and scream "LALALALALA" when real science is explained to them.
Go buy you some time on the Kek 1 and 2 telescopes in Hawaii. Those two can see damn near back to the big bang, you could probably see Armstrong's boot prints on the Moon
4 light years away and if it supernovas we will be dead on earth in just over 4 years.
the radiation from nukes would be trivial to whats already out there.
we have no clue whats outside the helioshpere
could very well crash into a rouge planet on the way there
Rockets aren't the only way into orbit, nor the best. They just happen to be the ones we use out of convenience because we do so little leaving the planet type work.
If you -really- wanna get shit into orbit on a massive scale you'd use a railgun.
We don't know proxima centauri's mass accurately enough for anything more accurate than an estimate of its gravity. The difference between 1.3 and 1.5 times earths gravity would be of serious consideration for living there.
Show me medical documentation that shows that connective tissue and lymph/nervous/circulatory systems can't stand the stress of an additional 2 m/s acceleration. Then show me scientific documentation that Proxima b has 1.3 times earths gravity.
Then I will concede the point.
>we have no clue whats outside the helioshpere
You do know that Voyager 1 has passed the Heliopause, right? Launched before you were likely born it has finally reached interstellar space, and it's just coasting.
People are shocked that that thing is still communicating, but it is.
>using modern economics to measure the cost of a global expeditionary effort
Look at this fucking capitalist right here.
Rockets wouldn't be used in a large scale operation. Space elevators and other methods would be much more cost effective.
Have you read a science journal regarding the state of space travel in the last 50 years?
>Why don't you grow U some fucking brains
What are you, 12?
We are talking relative to humans. The pressure at the bottom of the ocean is lethal to humans instantly.
Specifically we were talking about the long term health effects of living in a higher gravity environment.
acceleration of 2m/s is the same thing as saying 2m/s^. Learn English.
The stress refers to the stress on the human body from carrying the extra, relative, weight. Specifically on the connective tissues and systems in the body that don't use the skeletal system for support.
i'm not the one who said 1.3 times gravity, i said 1.3 times the size and "could" have a stronger gravity.
i'm not going to do the research for you, i already know a 30% constant increase would be devastating over prolonged periods.
i'm not talking about your lymph/nervious/circulatory systems, i'm talking about your liver, kidneys, heart, stomach, lungs, small and large intestine, gull balder, pancreas and bladder becoming detached and becoming friends with your prostate on the way out.
seriously, this is like playing chess with a pigeon
The effects of time dilation have never been observed affecting humans and perception.
>i'm not the one who said 1.3 times gravity
I know. The first thing I said to you was size and mass do not have a causal relationship. We were using 1.3 as a benchmark and 1.3 triggered you and possibly others into saying it was lethal to humans which it isn't.
I also pointed out that there is some indication that its gravity is actually lower than earths. Not much to go on but more than there is that would imply a higher gravity.
>i already know a 30% constant increase would be devastating over prolonged periods.
No you don't. You FEEL that it would. There has never been a medical study to suggest that it would. Also I notice you are back to using the 1.3 times benchmark too. Funny how its fine for your argument but no one elses.
>I'm not talking about your lymph/nervious/circulatory system
Why not? they would be under the same increased stress with no additional support.
>seriously, this is like playing chess with a pigeon
Nice meme. The problem is there is no study that proves your feelings and no indication it would be a concern in this scenario but you want to feel involved so you take your own feelings as facts to argue.
Show me that peer-evaluated study and I will accept that view point.
It makes me wonder if there is different habitual planets in the galaxy. What if there are more life forms out there. What if we could communicate with said creatures? Imagine the natural resources there. Maybe there are more humans elsewhere, maybe not as technologially advanced, or extremely smart? Honestly, thinking of these things late at night creep me out in a way, but always intrigue me as well
I thought we were talking a 1/3 to 1/2 G increase. Where the fuck did you get 300%?
1.3 to 1.5G is completely doable. Humans are one of the most adaptable forms of life on this planet.
Probably not actually but the other guy arguing about the health effects is doing it pretty badly.
A simple analogue would be truck drivers and the health effects they face from normal driving every day. The bouncing, which would only amount to 1 or 2 m/s^2 but over a career it causes serious health effects because of the stress on organs.
Granted it, the acceleration vector is constantly changing in that scenario where as on a planet it would be constant which would be less stressful.
It is a fallacy to assume that advanced life can only develop like humans did.
You would have to be a tool user to make the leap that we did with fire but not all tool users are humanoid.
There's tons of stuff a planet needs to be habitable aside from existing in the habitable zone.
Not too much gravity, liquid water, survivable atmospheric pressure, breathable atmosphere, not too much greenhouse gasses, magnetic field, etc.
People used to think Venus was going to be Earth 2.0. It's almost identical in size to Earth, has a magnetic field, and exists in a pretty close orbit to ours. Only problem is it has like a million times our atmospheric pressure and it's all CO2 and sulfuric acid.
As someone who does a LOT of driving myself, I don't really think the sedentary life of a truck driver really compares to a ship full of highly fit astronauts working and living a lifetime with a slowly increasing gravity.
What I would expect is that successive generations would grow to have a stockier build, heavier bones and generally sturdier bodies, including organs and connective tissue
>Trump gets elected because of time dilation.
>Dogs exist because of time dilation.
>I know God is real because of time dilation.
Atheists: 0 Christians: 1
Except the Christians actually have 10 because of time dilation.
I feel that it would have an impact but we are talking like a slightly elevated rate of organ failure in old age and slightly exacerbated pre existing conditions. Nothing lethal.
Also it seems like the strength of connective tissues can be increased with a careful diet which astronauts have and generational astronauts would have.
im not the guy you are replying to but its true. They were able to replicate the theory on a very small scale in lab conditions. Of course the means the technology is still a long way from being practical and even longer before it will be able to be implemented and used
>trusted enough to transport people
This is the real issue. It's still putting out more energy than we measure going into it for christ sake.
As for lab tests you can literally google it the articles and news reports are all over the place and there are even videos of it working and producing thrust.
Why do people even CARE about re-colonizing another planet? When it comes down to it, NASA will select probably no more 10 people every couple of months to go there, and guess what? You and nobody you know will be going...and it would not happen for another 25 years at best...and your grandchildren won't be chosen either.
elaborate what? Our exponential advancements in technology? If we don't blow ourselves up in 25 years, then we might just be able to stop burning fossil fuels by using cold fusion. It's going to happen.
>We already live in places that are decidedly NOT considered habitable for human life.
You are exactly wrong about that. Everywhere on earth that isn't a desert is decidedly habital for humans. Local flora and fauna may be hostile but that has nothing to do with the habitability of the atmosphere. We have evolved to live in this environment over billions of years. We couldn't just swap oxygen for xenon and expect to adapt.
The truth is the likely hood of finding a planet close enough to earth to live freely there is next to non existent in our galaxy not to mention impractical to travel to.
The most likely scenario is biodome installations on moons and planets nearby while terraforming technology is properly developed.
But Humans WILL, eventually, spread off this earth. That MUST happen. All our eggs, as it were, are in this one little basket in a dangerous and deadly cosmos.
Doesn't matter if it happens in my lifetime or 50 lifetimes, as long as it happens before some catastrophe befalls the earth.
Because we are always the stellar equivalent of a sneeze from extinction. A gamma burst from across the galaxy could sterilize this planet at any moment. A near-earth-object could hit and kill us all. Hell, the Yellowstone Caldera could pop it's cork and kill half the planet in a matter of months, and it's a few thousand years overdue.
They said the same thing about nuclear power.
I am very aware of the exponential rate of discovery and the fact that the earth is more peaceful that it has ever been despite what partisan media wants you to think.
