What will happen to our universe?

Question

does this boggle your mind, or is it just mine? when the outcome of our universe comes, whether it be the "big crunch" (where all the galaxies are compressd together forming a giant black hole), or whether the galaxies keep moving away from each other, which will result in all the stars dying out making it a cold and dark place. what will happen to the human race? will there be nothing? someone please help me understand this..

Answer 1

That is billions of years away and by that time we will have evolved beyond the need for physical existence.

Answer 2

Im not sure if ill help you understand better but ill tell you what i think.

Im pretty sure that the universe will end the Big Crunch style. I dont know why and i definitely dont know when, but its the most reasonabele theory, in my opinion because if the Universe keeps expanding, i dont think itll end it will just get bigger..

Answer 3

I think we're doomed either way, but we might not even last that long anyway. The Earth will be long gone before either one occurs.

This will explain a lot

Answer 4

The human race will be gone eons before that happens, so don't worry about it.

Answer 5

It has been known for some time that the Universe is expanding. This lead to the question, will it eventually slow down, stop, and then begin to contract(the big crunch)? Or will it just keep on expanding forever?

Astronomers have recently discovered that, not only is the Universe expanding, but that the rate of expansion is accelerating! At present, there is no known explanation for why this should be happening. With all the gravity containing within it, we would intuit that it would eventually slow and contract. But that is not the case. Not only is it not slowing, the rate of expansion is accelerating. At this time, we can only speculate about why this is so. Some have postulated the existence of some form of matter that we do not yet know about or understand, and that this matter(often referred to as 'dark matter') is exerting some sort of repelling force that is counteracting the gravitational force that we know exists.

Whatever the reason, the expansion of the Universe IS accelerating. This suggests that there will never be a 'big crunch', but that the Universe will expand forever. We don't need to worry about this much though. The Universe won't expand enough for anyone to begin to notice for at least a few 100 million years.

Answer 6

know one knows, christians don't know the whole truth, atheist don't know the whole truth, so basically what ever you want to happen is the truth b/c they've already proved the first second of the evolution theory wrong. and unless you have faith (by your question I'm asuming not) then you cant be a christian. So believe what you want that's the only choice you have left!

Answer 7

uh, the universe is 14 billion years old.

the sun and earth are 4 billion years old.

homo sapiens are 100,000 years old.

industrial homo sapiens are 200 years old.

technological homo sapiens are 40 years old.

40 years is .0000001% of the age of the earth.

keep in mind that 99% of all species that ever lived are extinct.

many of those are the result of cosmic impacts, which, if they were to happen today, would result it the complete collapse of civilization, industry, technology, the world as you know it, and, quite likely, the demise of homo sapiens.

in 5 billion years, the sun will flare up and engulf the earth, then contract, and explode.

we wouldn't survive that.

if you were to take the space shuttle to the nearest star, alpha centuri, it would take you 175,000 years to get there.  if you were to take the fastest spacecraft that man has ever launched, it would still take you 50,000 years to get there.

we're just a fleeting inhabitant of this world.

enjoy it.

show your kids the wonder of it.

don't worry about what's gonna happen in 5, 50, or 500 billion years.

trust me, it won't matter.

Answer 8

Long before the Universe dies, our sun will exhaust its hydrogen supply and be extinguished.  Unless humans (if you mean earthlings) have discovered the means of space travel at speeds approaching that of light or have overcome the laws of physics in order to emigrate to distant planets which may support life, while being unpopulated, our race will not survive the extinction of the sun.  Whether or not the Universe's fate is eternal expansion as you describe it or collapse is apparently dependent upon the amount of so-called "dark matter" present in the cosmos: the greater its quantity the more likely the great crunch will transpire.
