When does space End?

Question

I know this is an age old question. But time to bring up the question again. Someone told me it was like a ring, but then I said, whats outside the ring, he did not know what to say. He just looked puzzled and he said to me, ''yeah right'' I mean if there was a brick wall a billion light years away, then what would be behind the brick wall?? There has to be something out there so far we cant even imagine it, like another world maybe, if not, what a waste of space.

Answer 1

Where would you end space?

Answer 2

When space will end is anyone's guess. There are many educated guesses, but as of now, still just a guess.

Where does space end is another guess. There are different thoughts regarding this issue, but maybe somewhat easier to answer.

Currently there is evidence to support the idea that space is flat and expanding at an ever increasing rate, which would suggest that eventually the universe will expand so far that everything will burn out and our universe would become a cold dark universe.

According to quantum physics, our universe, observable and otherwise, is finite with definite boundaries; some call branes. One hypothesis is that there are multiple different universes bounded by branes. This is suggested by the study of gravity, which may be the only force that may be able to pierce the brane into other universes - all other forces and matter are unable to penetrate the brane - so we will probably never know if branes are a fact.

There are other ideas that include such things as different dimensions of space and time, multiple realities, etc.

One underlying theory of possibilities, according to quantum theory, is that reality, human experience, may not even be a reality at all. All that you experience may just be a random electrical discharge somewhere at sometime and that is all. Your universe may not even exist other than within the boundaries of this momentary discharge.

There is a new particle accelerator that is scheuled to be completed in 2007. It is believed that it may be capable of creating momentary microscopic black holes, which will shed some new theories of space and time.

I've heard it said that "space is a vacuum", but there is a lot of debris floating around in space. Comets lose material constantly, and there are alot of other heavenly bodies of all sizes and description just floating around.

The furthest reaches of the universe haven't been discovered by mankind. We're trapped here on this planet for the time being.

I'm not so much worried about where space ends. I'm concerned about the nature of the border between our dimension and other dimensions. Parallel universes could exist in the same physical space that we inhabit.

Back to my original thought, if space is a vacuum, that means that where there is no matter floating around, there is simply NOTHING! So, in reality, space ends where matter ends.

We think in terms of distance, like the distance between the earth and the moon, or the earth and the sun. But the distance from the outer edge of our atmosphere to the edge of the atmosphere of the moon or sun is not filled with anything. It's empty . . . it's nothing . . . so in effect, space ends at the edge of our atmosphere, and begins again at the edge of the moon or sun's atmosphere.

I'm just surprised all the gravitational masses, including the earth, moon, sun and planets, don't just crash into one another and pile up into a big ball!

That's why I believe in God. Unless there is an intellegence that designed the order of the universe, there's no way it could function so perfectly.

If you go to the planet praxalapretoriolominous they're very proud of the fact that their planet is egg shaped and the furthermost bit of the little end of the egg is in fact outside space and in nothing whatsoever. It's rather disconcerting being in nothing as you can't go up, down, sideways, forwards or backwards, only nothingwards. There's a certain kind of tree that grows in there that's invisible as it's growing in no direction and the native tour guides use these to navigate by; they hang big red signs on the invisible branches to see where they aren't. As the area is in nothing whatsoever there isn't any time in it and so it's not been unknown for a man to spend eight hours hanging big red signs on trees and returning to find that 30 million years have passed in real time and somebody's decided that the signs need replacing.
Because there's no time the locals have taken to using a large part of the area for storing perishable goods in and it's actually possible to have a steak from cows that haven't existed on praxalapretoriolominous for the last 4 billion years, mainly because the butchers slaughtered the lot to store as steaks.
Just before you go in to the little end of the egg there's a pub called the Fvsapdok and Whistle, and they've built a conservatory actually into the end of space so you can get a lovely view of the trees that aren't visible and enjoy a sumptuous panorama of nothing whatsoever whilst sipping your daquiri.
I believe that Lufthansa run a flight every Tuesday from Berlin Schoenefelde airport.

Answer 5

Listen up smart *** earthlings. Consider this. Something that your guru Einstein did not. What if you are a colony of microscopic bugs living in the hairy canals in the ridge of a giant beings a**e? What think est thou? All that space travel to the moon is nothing than a hop to a blob of poo on white Y front rears? And crude oil is nothing but drilling into a pimple? All metals are solid grit in the pores of sweat. Coal at the coalface? Get off the high horse for it too may be sub atomic bacteria. And climate change is just a hot flush?

Answer 6

this question drive me mad! and i and others don't know the answer to it and never will. But i believe that its about time we really put this question to bed and i will tell you why! its not where does space end? its when will the human race accept that there does not have to be and end to anything or a start or an up nor a down these are just words to try and describe something but in space terms there is no up nor no down nor no end nor a start! its just a gaping black expanse that are small narrow minds will never be able to comprehend. and we float around on this tiny ball we call earth thinking we are so big and important and wonder if there is other life out there? well i my mind 100% yes. and i only hope they are a more peace loving race of beings than we are and they steer well clear of our war torn, polluted ball of space junk called earth.
lol anyway that's my brain fried!

Answer 7

Space never ends so our view of how big/small it is will always be changing. The more we learn the more we know. And the more we know the more we can learn. The difference is in how much you can remember of what you have learned and know at any given moment. The universe could be able to remember everything it learns but can it do it all at once? One thing seems clear to me love exists and will always exist. Meaning the darkness can never overcome the energy that fills the universe. And we are all children of the universe and its energy becomes us as much as we become it. I hope none of that made any sense :)

Answer 8

Well it's like "The Truman Show" when he discovers the edge of the film studio. When we get enough brainpower together, obviously it will have to be a private project, we will discover the edge! At that point the "next dimension's" version of Jeremy Beadle will have no option but to show us what we've been missing!

I truly believe that universes live in my fingernails, just because atoms are the smallest things that we can see with our human eyes, does that really mean that they are the smallest things around?

Answer 9

I could give you the answer, but I feel that it would only result in more questions, and therefore you are not ready for it.

It's like - black holes suck in matter, and have been around for trillions of years, so why haven't we all disappeared into one by now?

So ... just accept your little part of the universe for what it is, and let the rest take care of itself.

Answer 10

According the most theories space is expanding at the speed of light, what its expanding into isn't quite none, perhaps its expanding in to nothing. In any case, it doesn't end, unless you can go faster than the speed of light, which you, I or anyone else can't.

Answer 11

Space doesn't end, it is pretty accepted within the scientific community that the universe has no boundary.
