What's on the outside of the universe?
Seriously, though? Whenever I look at the sky, I always wonder: what is on the outside of our cosmic bubble?
The universe expands at a rate of around 1 trillion trillion trillion light-years per second. It would take one heckuva rocket engine to get to its end.
But here's another random thought: compare the universe to a rubber band; when you pull it, it stretches. Like how our universe expands.
...But when you let go, it INSTANTLY snaps shut. My point is, if the universe were expanding, chances are its contraction would be around a 1000 times faster, so we'd never feel it.
Back on track: what is on the outside of our universe? It's like a video game: there's an invisible wall. There is another side. But you cannot reach it. If you try, your character dies.
It's impossible to imagine nothing on the outside of a barrier. What is outside the universe's boundary? What does that boundary look like? It freaks me out just thinking about it; like humanity isn't ever supposed to know the answer. Try it: try thinking of an "outside" to the universe. It will give you a headache.
What's preventing us from imagining the outside of the universe???

What's on the outside the Universe? Answer: Nothing. There is no outside of the universe. The universe is. Outside is not. The universe is not expanding [b]into[/b] anything. It is simply expanding. What does the edge of the universe look like? Answer: Technically you would never be able to reach the edge of the universe as it is expanding at the speed of light, faster than it is possible to travel, so you could never actually catch up to it. Even more technically to be able to see it would require photons reflected back off the edge into your eyes. As there is no edge nothing can reflect off it. However assuming you found a way to travel faster than light, you would never be able to reach the edge of the universe anyway. Travel far enough in one direction and you'll simply come back to where you started. Think of it like the surface of a balloon. The balloon can expand but if you travel on the surface of the balloon you'll simply go round in a circle. Are black holes, wormholes? No. Black holes are supercondensed remains of a white dwarf star. The gravity is so strong that the escape velocity is beyond the speed of light. Therefore even light gets sucked down making the 'hole' appear black. Wormholes are something else entirely and can be explained by string theory (don't ask). However wormholes only occur within this universe not between entirely seperate universes. Dark matter and dark energy? Even physicists have no idea. Definition: Matter that is undetectable by any means other than the fact without it the universe would be about 70% too light. Dark energy is the same for energy. For the those in the know dark energy has been proposed as Einsteins universal constant.

[quote][b]Posted by:[/b] muffin man from [quote][b]Posted by:[/b] Negative 1 Kills [quote]but sieriously i think that black holes are wormholes to a dark matter universe and in that universe there will be light holes i.e. the other end of a dark(black.)hole, but to the beings on the other side it would also be a black hole as dark matter is matter we cannot see. therefore dark matter beings would also not see them and it would show up as a black hole.[/quote] Do you know what a black hole does to matter? It tears anything that it comes into contact with into base elements. For example, if you were dragged towards a black hole ("dragged into" is impossible, because you would be ripped before you got to the middle) the sheer force of the hole would rip you apart into base elements/atoms. Since we are Carbon Life forms, then we would be torn into carbon, with all trace amounts elements in our body at the time. Of course, I am not expert, I just thought about it while I was writing.[/quote] the reason it would tear us is because it is a differant matter universe and we cannot exsist in that unniverse[/quote] I'd have to disagree with that--I would think it's just due to the increased forces of gravity. right now--if you stand up--the force of gravity acting on your feet is stronger than whats acting on your head--multiply the forces up for a black hole and you stretch and just get ripped to pieces on approach--we wouldn't get reduced to carbon though, or anything like that--all matter in a black hole goes to the singularity, which isn't really a type of matter, since the normal laws of physics breakdown in there--the gravitational forces are stronger than neutron degeneracy pressure--that is to say the forces are strong enough to overcome the physical strength of the atoms matter is composed of--which is pretty strong gravity to understate it.--so matter can quasi-exist, just not in a way we understand. Since a singularity is an infinitely small point of infinite density it's kind of hard to undestand how matter works inside a black hole, if at all.

[/quote] A worm hole could theoretically be created, but there is not enough energy to do so, and a worm hole is like two black holes joined, only without the singularities---join the tears in space time and voila!--wormhole--although that's putting it kind of simply. I'd have to disagree about your black hole definition though I'm afraid--white dwarves are too small to become black holes---after a large star goes supernova if enough matter is left to produce gravitational forces stronger than electron degeneracy pressure then electrons and protons are forced together and create neutronium--the most dense matter in the universe--a teaspoon size amount weighs thousands of tonnes. This is how neutron stars are formed (aka pulsars, since they are magnetised and spin on their axis, producing radio waves that mankind detected, thinking they were alien life trying to communicate--the first neutron star discovered was named LGM1-- (little green man 1) neutron stars in excess of approx 2 solar masses (i.e. over twice the mass of our sun) produce strong enough gravity to exceed neutron degeneracy pressure and the neutronium can't physically support itself under such intense forces of gravity and the neutron star will collapse into a black hole.

All I know is that if you go outside of the universe then the guardians will kill you. :o)

[quote][b]Posted by:[/b] elmicker The universe doesnt expand that fast, nothing can go faster than light, etc. etc.... Technically there's nothing on the outside of the universe, i don't mean like, vacuum, i mean NOTHING. so much nothing we can't even comprehend it.[/quote]

how is there completely nothing outside our universe? if there is nothing then is there really an outside? as our universe was compared to rubber bands, will we eveantuall run out of slack and break? or, what if there is another universe out there? is there life? if there is, how does it work, is it advanced, or still just catching up? what if there is something encompasing the universe, just like each and every individual galaxy? and now the question, what if there [i]is[/i] some higher being, like a god out there? i don't want this to turn religious so let's not look to deep into that theory. but how do we know for sure what we know?

When you think about things as big as the universe, you have to take into account things like other dimensions. Say that we were all two-dimensional, and lived in a perfectly flat universe. We might all think that the universe was like a really huge piece of paper, trillions of miles in every direction. But then we'd start to wonder: what's beyond the edge of the paper? But this question is meaningless if you consider the possibility that the entire two dimensional universe curves through a three dimensional space. What if we weren't living in a flat 2D universe, but [i]within[/i] the 2D surface of a 3D sphere? Everything would seem exactly the same to us, but there wouldn't be any "boundary" to the universe, at least not from our point of view. Maybe the same thing is happening to our universe. Maybe what we see as a "normal" 3D universe actually curves through the fourth dimension to meet itself in a way we can't imagine. And if you travelled for long enough in one direction, you'd go all the way around the 3D surface of this 4D "bubble" and end up in the same place. It's weird, but possible.

Some of this depends on your definition of 'universe.' I personaly describe it as everything - our entire space/time. So 'outside' would not be beyond the edge, but could be 'next to." But the original post (I believe) was referring to the 'edge.' I personally find the idea of both an open or closed universe scary... for diffrenet reasons.

[quote][b]Posted by:[/b] HaloFighter92 tecnically, another universe, think of it as a mirror. Thats my thoery at the moment. and when the ytouch(like in a real mirror), two events could happen, 1. the ywill go into eachother, causing parrell coliisens , but we wont feel it, since we are the same. 2. We bounce off and crunch, like the Big Crunch thoery.[/quote] *scoffs*

Its more like getting inflated with all these lame expalnations ever hear of "keep it simple stupid"? Think, but not too hard, k? The universe is nothing, you can't count, measure, follow, or reach the end of nothing. Da hell's wrong with people? Expanding? look up the meaning to that word, then try to point out where the center which its expanding from... A galaxy might expand, but nothing doesn't expand. How hard is it to understand nothing? its just empty space, there's no wall, edge, or end to nothing. Space starts from the air making contact with our surface.. Only difference there's an atmosphere, which is not enclosed in some magic bubble separating our air from space, which isn't just that "big'ol black thing" out there. Oh, and dark matter??? WTH, stop playing Metroid Prime 2, its getting to you! Funny, something so simple as nothing, and you guys make such a fuss about it? I'm still trying to understand real mysteries like why women are so complicated...

[quote][b]Posted by:[/b] dr rocko ya it's really confusing. someone asked wat is outside of the universe, and it got me thinking to a fiction book i read once, Enders Game and the other books branching out of it. if anyone knows about the books then u no wat im talking about. the book, which i remind u is fiction and im only refering to it to just state my opinion, says if u got out of it u would beable to make stuff out there, if u had a very powerful mind, so after u "make" the thing "outside"(out of the universe) u would beable to bring it back into the universe. so say u tried to think of a cure to cancers u could possibly make it by "thinking" on the outside and somehow bring it back. but, once again, this is from a fiction book called Enders Game. so theres my theory on wats outside. p.s. the books were awesome and i recommend everyone to get them and read them ALL!!!!![/quote]My thoughts exactaly

My crazy theory: 1: Einstein said that if you pick any point in the universe and move in a straight line, you will eventually come back to the point you started at. So, there is one universe but it is an infinitely recursive space. 2: There are two spaces: Three-space and four-space. Four-space is governed by four dimensions and is active vacuum that generates longitudinal-wave electromagnetic energy. Some of this energy travels to our three-space which generates time-velocity so we can have space-velocity. It is possible to travel to four-space: In the book [u]The Montauk Project: Experiments in Time[/u], a block of lead was supposedly placed in a Tesla Coil. When the coil was energized, the block disappeared. A knife was placed where the block was. When it returned to three-space, it overlapped with the block. 3: There are multiple realities. If there is randominity in one reality, all eventualities occur and a reality manifold is formed. If you exist in multiple realities, you may become concious of other realities, unless of course you are dead in said realities. Realistically, other realities may be mundanely similar to your own. Which means parallel you might not be a trillionaire playboy. Nice try. 4: As there is infinite free time-energy, this can become infinite free matter. Say the universe begins. Time-energy travels to three-space, generating matter. However, the universe is also an infinite recursive loop in time, so it both does and doesn't have a beginning. So, it has been here forever.

This reminds me of that professor who asked the students to write about a chair that was on the table, and explain why that chair didn't exist. Or using a 16 volume encyclopedia to explain the word Twinkie. My bad, go on. ^_^
