Do the Cosmos have the end?

Answer 1

Here's the theory. Space has been expanding for about 14.5 billion years. Everybody asks what is it expanding into? It's like asking which way is north if you're standing at the north pole. The universe, all 29 billion light years of it, is all there is. That's why they call it a universe. It's not expanding into anything, it's just expanding. There is no "outside" -- it's not expanding into black star-less space, there is nothing, not even time, beyond the expansion, and there is no center. You and me and a star billions of light years away can all claim to be in the center. This is very counter-intuitive, but so is the property of light and the properties of spacetime. Just because we can't imagine it doesn't mean it isn't what it is.

There is one provision, however. If the rate of expansion in the very first tiny fractions of a second after the big bang was much faster than it is now, the universe is not only big, but REALLY big. We can't see beyond 14.5 billion light years because light from beyond there hasn't had time to reach us yet. Alan Guth, a famous astrophysicist, estimates that if the very early inflationary period lasted longer than he thinks it did, the universe may be something on the order of ten to the twelfth to the twelfth power. The units don't matter with a number that large. Miles, inches, it's still bigger than beyond comprehension.

Answer 2

Does the Cosmos have an end? If this is your question than it can be interpreted to mean is there a wall or something out there where you can't go any further, if this is your question, then the answer is a resounding no.
If your question means will the universe ever end, then yes all the stars will burn out, all the gravity will end in all the black holes, the universe shall in all intents and purposes cease to exist but not for at lest a trillion years.

Answer 3

no.. "it's" not even a thing.. so having a word for it it what leads to these questions.. things have boundries...

if your speaking of time:
and no.. nothing has ever "began" .. at least i've never seen anything. things convert, react, change, and WE decide draw an essentially arbitrary mental line and give it a new name. thats us.. everything is in constant flux.. at all times..

but most importantly.. for a question so important we need to make sure we have the same definition of cosmos..

i will assume u mean "stuff" .. as in.. did stuff ever not exist aka matter and energy. the answer i think is no.. we cannot see past the big bang (if thats what happened).. so i suppose no one can tell you.. but i can say that there are plenty of reasons to think what is here has always been here..in a different state.. but here none the less.
and there are absolutely no reasons to think that anything ever began... given that we have never seen that..

humans just tend to naturally think that things should begin and end.. because we begin and end.. but one must realize that we are just a certain configuration of matter, and that are matter does not begin or end..

it is important to seperate the beginnings and ends of the configuations of matter from matter/energy itself.

Answer 4

For there to be an end to our universe would require it to be inside of some "thing" else. There is not one single bit of evidence that such is the case. In other words, science doesn't know.

Answer 5

I would love to know. I don't beleive in eternity or infinity, so I don't really beleive that space is endless. But I would like to know what is beyond all that blackness.

Answer 6

Yes. It's already happened many times.

Answer 7

Don't know yet because we can only see so far.

Here's what we can see.

Answer 8

nope it's infinity

Answer 9

dunno dude! that's like trying to see across town on a real foggy day!
