>>701023614 Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space.
>>701023614 We can only observe about 60% of the universe. A large portion of the universe is blocked by our own galaxy, dubbed "The Zone of Avoidance." We can't see through the cloud of stars.
However, within this Zone of Avoidance is something known as The Great Attractor. A supermassive object of unknown composition and origin which singlehandedly contributes to the accelerated expansion of the universe.
the reason why "dark matter" exists is because the predicted radial velocity of galaxies is incorrect after a certain distance, and we didnt have the proper equipment to observe this in einstein's time. so his equations came out wrong and so scientists now are scrambling to explain why and cant explain it
Pretty much this. It's almost terrifying trying to think about how big one light year it, let alone billions and billions.
The fact that the universe is really that big, way beyond our comprehension, is what really fucks me up the most. Our lifetime is minuscule and insignificant in the grand scheme of things.
I find it frustrating that there is no way we will really understand everything there is to know about the universe. 50 years ago the technology of today would have blown our minds. What we will learn in another 50 (or 500) would more so.
>>701023614 The Bootes void is a region of space multiple hundreds of millions of light years across, with only a few hundred galaxies within it.
This may be the result of a hyper advanced alien civilization that has harnessed the power of entire galaxies and is expanding across the cosmos.
The star Betelgeuse in Orion is visible from earth as a bright red giant. We may very well see it explode in our lifetimes - of course the light from its explosion will take hundreds of years to reach us.
As a tangible fact, when you look up at the night sky you are essentially looking back in time, as the light from the stars left centuries ago. Some of the energy your neurons are interacting with occurred at the same time as the invention of writing, the Roman Empire and the Renaissance, among other things. Those tiny packets of energy end their journey on your retina, after hundreds, perhaps thousands of years. Think about that. Traveling through the void of space for thousands of years, only to see the earth emerge over a period of a few minutes or so, and before you know it, a flash of blue and then the back of a humans eye.
Right now there are likely alien species shut posting on their version of this website, contemplating the universe in much the same way as we are right now.
at this point in science tech, we have successfully been able reach fusion that outputs more energy than inputted.
however, it has to be extremely extremely hot. however, we overcome this by using superconducting electromagnets to trap the plasma
superconducting is about to be a huge field... basically that means at cold temps, resistance is essentially zero. i can talk about this forever...its extra interesting because if you think about types of materials, we have polymers (plastics) metals, and ceramics
metals are flexible, malleable, good thermal and electrical conduction.
ceramics are the exact opposite; brittle, dont conduct electricity etc
however, around 90K, these ceramics have an electrical resistance LESS than metals. which is crazy.
we currently have "invisibility" cloaks, but the issue is they just cancel all light. they are pure black. we cant figure out how to bend the light behind us perfectly in front of us...
i did research with MIT for 10 years if anyone is interested in other stuff...
The universe is infinitely small to a massless photon particle. It spans space at the speed of causality since the universe is contracted so greatly from the perspective of the particle of light. We see the light as it was hundreds of years ago.
We will never escape the Local Group of galaxies based on our current knowledge of feasible space travel (IE no wormholes, Alcubierre drive etc). If we left at the speed of light right now to exit the local group, by the time you went far enough to have reached outside the group the surrounding galaxies will already be expanding away faster than the speed of light. This could of course change based on phenomenon we haven't observed yet or something else unprecedented in the future but it's not looking promising right now
>>701027053 So I guess you don't believe in atomic theory then? Or germ theory? Or the big bang theory, or the theory of relativity, or all these well proven, well documented, well tested scientific statements about the causes of observable phenomena?
Cannot travel at or faster than light. Time would stop and universe would be as thin as your penis. If you traveled near The speed of light, the distance between galaxies would shrink. From someone watching you zoom away, they would see you make the 2.5 million light year journey to andromeda. To you, the journey would be considerably less
>>701029024 that's assuming that we are the ones who are normal size there might be other entities or beings out there who are smaller or bigger than us just because we like to think that everything is normal from our perspective doesn't mean that it is normal is like asking a fish if there is life outside water
>>701023614 Space is infinitely vast and infinitely old. All matter is recycled and transmuted in specific sections of space where it is than distributed to a new galaxy when older galaxies are destroyed via the triad spiral effect. Where two smaller galaxies are eventually pulled into a larger galaxy (a galaxy cluster) they eventually become either a super galaxy imploding on itself and shooting its spacey nutrients across the ether or continue the cycle of spiraling around absorbing other galaxies. Our galaxy was made in such a way, with a surprisingly large amount of carbon, considering most the known universe is theorized to be silicone based. This luck of the draw allowed the creation of our planet. In this universe (as far as we can see into space) alone there are countless galaxies and solar systems. Probability would dictate that there would be at least one other planet with carbon at the exact distance away from a sun to create carbon based life.
Our known universe probably doesn't take up even a single percent of space. Sadly we will never know, as such distance would take even at the fastest speed possible countless years to reach. Like some Warhammer40k self insert fanfic we would probably forget why we even started the journey and aimlessly go from planet to planet before we actually reached any edge of our seeable universe. There are probably multiple universes, and much like galaxies and solar systems. They more than likely rotate and absorb each other.
>>701025790 I'm extremely interested. For the past 20 years I've been interested in space and its mysteries. One thing that I find is hard to explain to people is space-time and how time is relative to where you are in space.
>>701028758 um...of those 4 only 2 are widely considered to be facts. And atomic theory is just a stop gap between classical and quantum physics anyway.
The big bang theory is incomplete due to the CBR blocking our view, and relativity has been revised so many times it barely resembles the original equations. Not to stomp on your point, but just saying
>>701029336 Bruh you don't understand. Aren't we about in the middle (size) between the observable microscopic and the observable marcroscopic? Well not observable, but you know what I mean faggot, quarks n stuff
but when we think of "speed of light" its actually the speed of all electromagnetic info. therefore we cannot see into a blackhole. if i remember correctly, if you would get pulled into one, your imagine would remain at the event horizon forever
that being said, our universe could be a blackhole and we wouldnt know, since we cannot see out of it. there could be universe in every blackhole...if you look up einsteins theory of gravity equations (which are basically 27 equations that describe motion in every dimension)
think about general relativity like this:
if you were standing at the north pole and walked in a straight line until you reached your original posiiton, to you, you went in a straight line.
however, an observer on the moon would see you do a circle. einstein visualized this dilemma on a napkin and on his own derived a series of equations to describe your motion through time and space to all possible observers.
>>701029336 Mass of an electon is 1 x e-30, mass of the sun is 2 x e30. Humans are near the middle point. Most life probably would be as well, bacteria is closer to the middle point than to electron scale.
Fun fact: Space is a Canadian Category A specialty channel owned and operated by Bell Media. It features science fiction, fantasy, horror and paranormal programming including scripted television series, films, documentaries and more. The network's original slogan was The Imagination Station, still sometimes used informally by fans.
If information/matter goes into a black hole but cannot escape, where does it go? Since a black hole is not a 'mass' or 'object', why does it get larger as it eats more matter? Does it increase the size of the space/time singularity?
When we have a perfect vacuum, we ca observe quantum fluctuations. Could those be 'popping' in from another dimension or possible black hole?
>>701030489 interesting when you consider why we can't hear anyone out there (from any nearby locations in our part of the galaxy) differences in TIME would either mean intelligent life either takes a long long time to evolve or it appears and disappears in a blink of an eye
this is a tough subject. something has to be responsible for mass BUT if you look at where it stems, theres a huge issue with our standard model of the universe called The Grand Unification Theory. basically nothing should exist as it is. in short:
our four forces: gravity, electromagnetic, weak/strong nuclear force theoretically came from the same place BUT
electromagnetic force is 10^27 times greater than gravity, and the trend continues the stronger you go.
>>701030893 Fun fact: more and more people are watching less cable and satellite tv and opt to watch content online when they want at their our leisure - rather than wait for a station to broadcast it for them at inappropriate times (ie: 4-in-the-fucking-am)
humans miss almost everything they observe. Move your hand fast in front of you face. You see that blur? Thats your brain missing information being sent to it via sight. Your eyes receive the photons from when your arm is in motion but your brain cant keep up so it makes do and joins the images.
The screen you're looking at isnt even showing a constant light. It's flashing at you 50-60 times a second. The human brain cant conceive shit. We have no intuition when it comes to microscopic scale or anything larger than a mile. Time always changes for us too. When the day drags or when you stare at a watch hand moving etc...
why does every star seem to be moving away from us? with the exception of the andromeda galaxy. is there, by chance, any other reason red shift would occur? what if this is just the telescoping effect of light over a long distance? could the "expansion" of the universe be incorrect in that case?
>>701032536 black holes do have matter, they're just incredibly dense - imagine the Sun but taking up the space of a rock instead of the fucking huge ball of gas it is now - and then imagine all the matter inside it (like the Earth orbiting the Sun) as existing between the event horizon and the actual physical object at the centre
>>701030667 >>701029666 I don't think either of you will debate the validity of germ theory or atomic theory. One of you mentioned atomic theory being more of a transition from traditional particle physics to quantum mechanics but I don't see why that makes it false. I name these things because people want to immediately dismiss evidence because it has "theory" in the name, even though a scientific theory is radically different from the word theory that we use in everyday conversations. Regardless, I don't know where you got the impression that the theory of relativity is incorrect or distorted, since it's what we base most of our mathematical predictions about space around, and they come out incredibly precise. In fact, yet another piece of evidence notched in its favor as we detected gravitational waves for the first time, predicted by the theory of relativity decades ago. The big bang theory on the other hand is equally well proven, but I think you have the wrong impression on what exactly it is. The big bang isn't a description of the origin of the universe, but rather an observation of the evolution of the universe FROM its beginning. The big bang theory has been extrapolated from star formations, the presence of microwave background radiation, the current observable expansion and the origin of its trajectory, as well as various other proofs based on chemical compositions of the universe and properties of light.
No, they don't. Kip Thorne has a good presentation online where he discusses this. Kip Thorne is the directing physicist of LIGO (Recently discovered gravitational waves), was the consulting physicist for Interstellar and has decades of experience writing about/studying black holes.
Black holes may begin with some matter but it's quickly destroyed when a black hole properly becomes a 'black hole'.
>>701023614 Not so much "space" as much as "general cosmology," but whatever.
>"Given enough time, hydrogen begins to wonder where it came from, and where it's going." -Edward R. Harrison
Everything in the universe is made of atoms, which aren't sentient. But eventually, they form molecules which eventually become self-replicating, and life begins. Once life begins, it only takes time before those tiny, inanimate building blocks of matter can reflect on their own existence and wonder if there's a purpose to the whole thing.
That shit blows my mind and really makes me think about the origins of life, the purpose of it (if there is one), and why things work the way they do.
There's about 10^80 estimated particles in the universe The further you observe space, the further back in the past you are seeing There are gigantic areas of the universe that are completely empty. There's one supervoid 1 billion light years across.
>>701034098 same here - i used to freak out and cry about it .. how about this for a thought there is only one individual mind in the universe who is capable of existing at different times and places all at once when you die, you come back as another individual in some random part of the universe at a random time period this means, i am me, you are me, i am you, i am him, i am her, i am the being on planet x, a being on planet 209309834 and i exist now, i have existed and i am going to exist
the matter is torn apart completely until all that's left is whatever the fundamental thing is that matter is made from. Whatever is below the prions that make quarks, or whatever is below that. When it's something so small and high energy we have no possible way of understanding it yet, it wouldnt surprise me if things like quantum superposition have no meaning to it and you can have entire galaxies worth of the things taking up the same space at the same time, each with so much energy you couldnt reasonably calculate it, but going nowhere because they keep each other in check.
>>701032536 the matter goes into a region of space with infinite density. It obviously transforms in some way but we can only theorise on how and into what as physics as we understand it doesnt work in that region of space.
What really confuses me is that there are black holes that spin,so somehow angular momentum is conserved but obviously it cant be rotating. How can something rotate if it has no central point. It IS the central point. My head hurts.
>Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.
>>701027885 that's not the problem you cumstain the problem is that you're part of the reason /b/ went down the shitter >inb4 /b/ is the shitter >suck my cock nigger I would say that your shitty meme killing website can get ddosed and taken down by some edgy teenagers, but that would mean you would all start flooding here
piss off to your own damn shit-show of a site faggot, this one is ours
>>701027044 How much do you know about dying stars and gamma rays? I did watch a doc about it a week ago and it was fascinating. I mean they did prove it with measurements, but how the gamma rays form and what kind of a beam they emit? Is it a cone or a sphere everywhere? It's a scary though any second a gamma ray would hit us and we would ALL burn to a crisp all around the world.
Here is an interview with Kip Thorne, one of the 3 founding members of LIGO, probably Nobel Prize Laureate for his discovery of gravitiational waves, lead scientific adviser to Interstellar and winner of more honors/awards on his work with Black Holes/gravity than I can post here.
Also, remember that bet that Hawking made with 'that other guy and lost' over the nature of black holes? Yep, Kip Thorne was in on that too. So, let's see what he says about black holes;
"Thorne: The matter of which a star is made, the atoms of which a star is made, are destroyed at the center of a black hole, when the black hole is created. The matter is gone, but the mass, in the sense of mass and energy being equivalent, has gone into the warped space-time of the black hole."
Kip also explains this in his book on the science of Interstellar. This is not junk or fringe science either, this has been discussed ad nauseum in physics for years, so I'm not sure how you're so surprised about it.
>>701034098 Me too but i was like 4 and playing in the yard when it hit me. I started crying and screaming I don't want to die. So my folks started telling me fairly tales about Heaven and God and Jesus to try to make me feel better. And for awhile it worked but then I realized that Man made all that shit up so ever since then I've been a miserable bastard.
>>701035075 i thought the same thing but was never able to find any movie with that premise or idea i always thought it would make an interesting movie you die, come back have no memory of past life, live in the 20s, die, come back in 2023, die, come back 10,000 BC, die, come back as alien on another planet, die, come back to earth in 1890s as hitler, die, come back as a jew from 1910s in germany, die, come back as alien in next star system 400 years ago, die, come back as ww2 russian soldier, die, come back as worker of some sort in 3044, die, come back as french farmer in the first war, die, come back as alien on opposite of planet a million years ago, die, etc etc etc etc in the end it would mean that there is only one lonely intelligent life form
>>701033357 ok, well there have been numerous relativity theories. I think you're talking about the general theory of relativity which is correct most of the time but there are numerous problems with it. String theory came about trying to solve one of those problems. It's main issue is that it isnt a unifying theory. It doesnt work for sub atomic and galactic scales. Dark energy and matter are also consequences of it not explaining stuff.
The big bang is incomplete as we cant see past a certain barrier. It again isnt fact because we dont know everything FROM the beginning
Let’s say we have an ant hill in the middle of the forest. And right next to the ant hill, we are building a ten-lane super-highway. And the question is “Would the ants be able to understand what a ten-lane super-highway is? Would the ants be able to understand the technology and the intentions of the beings building the highway next to them? So it’s not that we can’t pick up the signals from Planet X using our technology, it’s that we can’t even comprehend what the beings from Planet X are or what they’re trying to do. It’s so beyond us that even if they really wanted to enlighten us, it would be like trying to teach ants about the internet. When Pizarro made his way into Peru, did he stop for a while at an anthill to try to communicate? Was he magnanimous, trying to help the ants in the anthill? Did he become hostile and slow his original mission down in order to smash the anthill apart? Or was the anthill of complete and utter and eternal irrelevance to Pizarro? That might be our situation here.
This may be more philosophy than a fact but as the oceans where placed there so that humans can create ships space is "there" so that humans can invent transcendence from organic to inorganic post humans. Every planet in our solar system has a resource that is meant to be used once we reach said phase. This isn't about God or anything but the universe and the self are conscious of one another. Look up quantum biology for further reading
>>701034372 and eventually those atoms that make up life work out that the universe will go on forever and that it will be a relatively short time before life as they know it can no longer come about because all matter will eventually combine and decay into photons
>>701036574 Fair points regarding the theory of relativity. Yet again I have to say that it's not factually incorrect, but simply another piece in the puzzle. The original comment I replied to implied theories are guesses at best and we don't actually know anything which is blatantly untrue. As I pointed out, the theory of relativity is our go-to for mathematical predictions as of right now. It's precise enough for the purposes we use it for which would be impossible if it were a meager guess, though I'm sure an even better version will emerge like when Einstein surpassed Newton. This means the big bang is not yet complete, it does NOT mean it is false. The time from the beginning of the big bang to the time where we can see what happened is around 2 seconds. The universe is 13 billion years old, and the theory applies to this massive time period. My examples were perfectly valid, your interpretation of my comment (theories are more than guesses and have significant evidence and proof vs a theory is automatically correct and complete) was flawed.
>>701029584 i remember smoking weed one time and seeing this picture and started actually crying. Since then its remained as one of the more powerful pictures ive ever seen. I get a lot of different emotions when i see it
on a related note. Whos excited for the james webb telescope? (assuming it ever actually gets finished and launched)
for all we know we're the only ones out there with any understanding at all. Do you know how many convenient events had to take place for tool wielding mammals with the ability to think about the universe had to arise had to take place in the right order? For all we know everywhere else gets to the dinosaurs (or whatever their version of an apex predator species that lives at the top of the food chain basically indefinitely) and stays there until their planet cant support life anymore. I like to think of it that way, that it's entirely up to us to figure everything out. Gives me a sense of purpose to human life that we otherwise dont have.
Here's a good one, should fit right in here on /b/...
The earth's "radio bubble" is roughly 200 light years in diameter. However, because of the strength of those early signals, most have probably dissipated. It's very likely that the first signal any aliens would hear from earth would be adolf hitler's broadcasting of the 1936 olympics, that were held in germany. Hitler wanted the whole world to hear the olympics, so special equipment was used to broadcast with more power.
>>701037325 Wasting taxpayers dollars on humans ins space. Space is not intended for humans. It would more fiscal to spend the money on neurology and uploading and downloading ourselves from one planet to the other instead of creating spacecraft habitable for organic matter
>>701037073 It's not pointless. It can't be proven to anyone but the person making the assertion, though. "Asserting," in this case just means that when examining the world, the only thing I can KNOW for sure is that my own consciousness exists, because without that, I couldn't conduct the examination to begin with. Descartes went though this whole thing ("I think, therefore I am) and concluded that while his senses might be wrong or some force might be manipulating his mind/perceptions/thoughts, he at least could know without a doubt that he had (or was) a mind, because he could at least perceive and think, even if the content of those perceptions or thoughts were somehow suspect. He couldn't vouch for anyone or anything else, though. That much makes sense to me.
He eventually took that and ran with it and claimed he could know that God exists too, but without getting into the details, I found it to be a bit of a logical leap.
>>701025113 > I find it frustrating that there is no way we will really understand everything there is to know about the universe. You don't know that. Maybe your consciousness continues in another form.
>>701038509 Fuck, a novel? How old are you? Also, yeah I barely use Reddit, didn't even realize karma is important to people. I like the idea that people can be credited with a title next to their name in science boards, you should be there fam
Ceramics: bad energy conduction of any sort (mechanical, electrical, thermal, etc)
this is because of the bonding. ceramics use a covalent bond. this means that the bonds are "happy" almost everything in nature is a ceramic. it is what materials want to be, because they have full shells and want to stay that way. hence why rocks stay rocks but metals rust into ceramics.
this is because ceramics have only "shared" electron bonds.
metals, on the other hand, have what we call a "sea" of electrons. that means that if you have a hunk of metal, an electron from an atom can be ANYWHERE in this hunk of metal at anytime. therefore, metal conduct all things that interact with electrons well, and since ceramics cannot move their bonds without breaking (ie brittle) they cant
at cold temperatures in these ceramics, electronics appear to move through they as if there were no atomic structures or bonds in front of them.
i know the retard answer is research/trial/error/experimentation but i want an in depth answer if possible
but ive always been facinated at how people can interpret and truly understand whats happening around them. Especially the earlier scientists who had such limited resources and had to damn near dedicate their whole lives to one thing
>>701038462 I agree with you totally sorry for the bad english btw. Didnt mean in comparison to other species or other posible civilization i meant that due to the short human life there has to be a lot more to know, and we wont, you or me or our children etc.
