Space- Endless or Not?

[Camazotz]

Do you think space is endless? I dont fully understand. So space goes on forever and ever? Or does it stop somewhere? Whats at the edge of space?

If space is endless, isnt it possible there are planets exactly like Earth in different universes? Isnt it possible that there are aliens that are exactly like humans?

If space ends, where and how does it end? A giant wall? Or like a cloud that you cannot go beyond?

[Hauptmann Kauffman]

I believe space goes on endlessly, forever and ever.

[Patchy]

I believe space goes on endlessly, forever and ever.

So do I, stars upon stars

We don't really have the answer to that
for all we know space could be curved much like earth is instead of flat
Its actually really easy to warp space time
The sun does it if you blot out the direct light of the sun so you can see the stars around the sun your actually looking at stars that are behind the sun but its gravity bends the light around it

Its not only possible its HIGHLY like HIGHLY probable
Just a few billion yrs ago mars would have been similar to earth, even oceans

Europa is though to have a HUGE like i mean HUGE ocean under a layer of ice a few km thick if thats true then its been around allot longer then it took for earths oceans to produce life meaning there could be live aliens orbiting on a moon around Jupiter

If thats true then just in our solar system alone three separate habital worlds could have existed, well two and a moon

and thats just here

theres billions of other stars

who knows how many worlds

[Underground_Network]

It really depends how you define "endless". I mean, in a sense I think it might have an end, I mean I don't see how it could be completely endless, but I believe it is extremely wide, and that no matter how far we could see, if there was an end, we would never see it. And I believe that in other galaxies there are probably beings much more complex than us inhabiting planets that we may never locate.

I agree

Space is endless and goes on for infinity.

[Half Angel]

It is endless if you look at it my way. Think of a wall, now there has to be something on the other side of the wall, doesn't there? So if there was an end to the universe, there has to be something further than the end. There always has to be something beyond that wall. It's something the human brain finds it hard to grip on.

[Doc.]

There is and end to space, anyone who takes a interest in quantum mechanics and higher level astronomy would know this. The universe is expanding, this is because of dark energy and the big bang. So the universe is not limitless, since it has room to expand there is something beyond that of our universe. Perhaps some sort of void like a white hole that acts as the boundary between alternate (parallel) universes.

[Malcolm Tucker]

Space is constantly expanding. Recently, Irish scientists have been able to look to the edge (as such), by looking at a certain spot with a certain trojectory. It is possible to see accurately the state of matter that the Universe was at the time of the 'Big Bang'. It is constantly exapanding so in therory, the 'edge' per-say is always at the state of matter the Universe was at that time. It is, If I recollect correctly that it is red gases.

Interesting. I am actually thinking maybe at the end of space if it does end it is all just a giant black hole with almost takes u to the next universe

[Doc.]

Black holes don't do that, it is also impossible for a black hole to span the boundries of the universe. They are formed when a massive star runs out of elements to 'burn' and it collapses in on itself creating a black hole with infinite density. It would rip you apart atom by atom, not transport you.

Indeed, movies have bad influences on people lol.

Not Likely. If that were the case, then it wouldn't be expanding. Plus they would be engulfing eachother.

True, but no one can be 100% as to the effects as to what happens in a black hole.

[Doc.]

Are you kidding me? There is scientific evidence proving that it has such a gravitational pull that it literally rips things like stars, planets, gases, pretty much everything including other black holes apart atom by atom.

It's the same as the 0,999... = 1 argument. And that is much simpler. I cannot understand if the universe is eternal (I can think it, but not understand it), nor can I understand if it isn't eternal.

Oh, and by the way, the 0,999... = 1 argument, I usually visualize to understand. Imagine a two-dimensional shape. It may not be more than n units from one edge to another. Now, imagine that you make the differences smaller and smaller, and essentially it is a circle. It is a circle.

[Emryl]

I think there is an end. But once we get passed by that end, we reach true forever. Kind of like going out the door, your outside.

I also have another theory that the universe could be repeating. Like looping a movie.

[Zephyr]

It truly is hard to wrap the human mind around the subject of space. We may not ever find out the truths that space holds for the pure fact that it is so massive.

We all know that the speed of light is unmatchable, at least in this lifetime (perhaps for forever). But the next time you see a shooting star, think about this: That star died 100 years ago, and you are just now seeing it. It took 100 years, and at the speed of light, for you to see that shooting star that died back in 1908. (This is just an average figure) This gives only a small iota of an idea of how massive the vaccum of space is.

As for black holes... they are stars that have impolded on themselves. Once they get down to the size of an atom, they start to rapidly expend(at least this is the common theory that I hear themost), and scientitst have even found out recently that black holes move around the universe. They believe that if you were to enter a black hole, it would start to stretch you out and rip you piece by piece at an exponential rate.(If you want to see a black hole, just look at the middle of Orion's Belt... that is a black hole)

Aliens: I truly do believe that it is probable that there is other intelligent life forms out there. I did hear a while back that scientists believe they have come across a universe very similar to ours, with a planet like earth. This is still a very new finding though, and they may be wrong. As for aliens being like humans, highly improbable due to the theory of human evolution from single celled protists. An alien life form that has the same genetic makeup of humans that are lightyears away is literally right next to impossible unless God really does exist and has worshipers on other planets that he made the same us as. (I'm Atheist, so this does effect my thinking)

Universe (http://en.wikipedia.org/wiki/Universe)

If you can understand it, that sums it up. The universe is endless as in it keeps expanding forever, but if you freeze time (lol) it technically does have an "end".

[japanman]

who knos just think about our earth we spend too much time on therios and the galaxies et when will we are doing this our planets dieng pay attion to earth:cool:

[ThatCanadianGuy]

I think we're really just too small to contemplate something so amazingly BIG in our lifetime. But at least concerning other planets that have life like ours.... the answer is DEFINITELY. Now I know Earth was an EXTREMELY lucky combination (ie its distance from the sun) in order to support life, but think about it. There are BAJILLIONS (lol yeah :D) of stars... its not that unlikely that this "lucky combination" has occurred even hundreds of thousands of times.

[The Entertainer]

Space is odd. Just a very brief example, if you set out towards the edge of the universe you would never get there, as its expandind faster than you could get there. Presume you could, however, and something really weird happens. Youd end up at the place you started at. Space folds over itself and does an all manner of crazy things.
I wouldnt think about it! Just accept youre incredibly lucky to exist (not only did the conditions on earth have to be perfect, but humans had to evolve, and your parents had to meet, and their parents had to meet, and their parents, and their parents parents etc...)

[chris__robin]

i believe that the universe is endless ... and if not i think it would take a very long time to prove or otherwise.
for now we only have our theories and hypotheses.

but .. you know when people here say that the universe is expanding .. into what space is it expanding into? i mean from a human understanding, if we blow up a balloon(space) inside a box ... is the room inside the box the area the universe is expanding into? is that considered something separate from space?
i think im confusing myself here.

I think that by "the universe" expanding, it means that the stars and matter are going out. So they are expanding int empty space, which goes on forever

[Chatsworth]

This universe is to big for just us to be the only ones here to enjoy it

[*Dissident*]

there are many theories that explain the existence of gravity that have to do with a "Multiverse" as opposed to a universe. Gravity, unlike the other 3 primary forces (electromagnetic, weak nuclear and strong nuclear) has no classical explanation. So far, a popular theory is that is "leaking" into our universe from another, and that explains both its origin and why it is relativly weak compared to the other 3 forces.

this "multiverse" concept -- a vast expanse of multiple if not an infinite amount of seperate universes with their own laws of physics -- seems to suggest that our universe is in some way finite.

Many other theories suggest (einstein did as well) that the universe is looped. Einstein theorized that if you traveled at close to the speed of light for billions and billions of years in a straight line, you would eventually arrive back where you started.

Many scientists believe that the universe is shaped like a 3 demensional figure eight type thing...a never-ending loop.

Man my father would probably want to read this, he loves the scientific things with the universe and Einsteins theroys:D

Do you think space is endless? I dont fully understand. So space goes on forever and ever? Or does it stop somewhere? Whats at the edge of space?

If space is endless, isnt it possible there are planets exactly like Earth in different universes? Isnt it possible that there are aliens that are exactly like humans?

If space ends, where and how does it end? A giant wall? Or like a cloud that you cannot go beyond?

thats my cue for goin back to bein a science nerd for as long as i type this response.

Space is a complicated formula of extremely large amounts of elements. Space does not simply "go on forever" it grows. It is true that every single second space will grow, because it is a growing mass of elements.

Not only did grow immensely fast at the big bang, it then slowed down immediately after a few million years the universe was forged. Due to the extreme cold of space, it is constantly slowing down, and nobody knows if it will ever stop.

but a question also comes out of that "If space is growing, can we go to the edge of it now and watch it move?" and my own answer, no. The universe contains everything that exists so it is extremely dense, compact, and fast. I believe it went about 500,000 times the speed of like (186,000 MPS) in the begginning and now it is believed to only be 10,000 times the speed of light.

the only way to go faster then light is to warp something or to have immense gravity/density.

some are also wondering "why does the universe grow" it grows because it has to expand,due to fluxuations through elements.

ok nerd mode off hope this helps any science lovers. ask me anything btw.

[The Entertainer]

I would have to disagree with the theory that the universe is slowing down. It has been proven that it is expanding exponentially, i.e. quicker and quicker.
In other words, it seems to disprove, for the time being, the theory of the Big Crunch.
To answer the above question, I havent a clue what the universe is exanding into. I always like to think of it as nothing. Everything that exists has to be in the universe (so we are told by scientists) yet anything outside of that doesnt exist. So the answer must be that it is expanding into nothing.
What does this nothing look like? Well, I suppose it would look like "nothing", though not just a black space, more...nothing (confusing!).
We would never have to worry about that though, as it is impossible, according to Einstein's General Theory of relativity, to reach the end of the universe. It is beyond the laws of physics, and, even if we did, we would end up at the place we started!

Strange place this universe...

[Mzor203]

Space has to be endless, because since every piece of matter makes some gravity, if there was a limited amount of stars eventually all would be pulled to one place, which isn't what is happenning. If there was an infinite amount of stars, all stars would exert gravity on all other stars and then even things out a bit.

Of course, there could be another force at work that we aren't sure about.

I always feel like I want to drink a lot of water and then piss it all out really fast when I think about things so big it hurts my brains. Just something odd about me. This falls into that category.

[The Entertainer]

what evidence is there that if there was a limited amount of stars, then they could all be pulled into one another? If you accept the Big Bang theory, then space cannot be endless.

[Mzor203]

The big bang theory states that an infinately large amoount of matter exploded out from a minuscule amount of matter, so who knows what could happen when something like thathappens.

[JoshDude]

Well, if space doesnt go forever, whats beyond 'space'? Just like Earth. If you keep runninging east, then swim through water, and always go east, you never escape earth. If you use a rocket ship, you can 'escape' earth, but you're now in space. Can you escape space? Probably not. But in the distant future. Maybe 1k years, scientists may work it out.

[Techno Monster]

I think it goes on forevr but that is just me.

[The Entertainer]

The big bang theory states that an infinately large amoount of matter exploded out from a minuscule amount of matter, so who knows what could happen when something like thathappens.

surely the matter would have had to have been a finite amount? If it were infinite, space would be endless, and so therefore contradicts the Big Bang theory itself

[tombstonequeen]

it goes on for ever

[BornActor]

Well, the Big Bang theory is really flawed anyway.
