Will the universe ever end what do you say about it?

Question

if yes how

Answer 1

I've pondered on this statement in my life for a loooong time. In my opinion, I understand how the universe began, I believe it started from the big bang, and the universe is continuously expanding. It will eventually collapse upon itself causing, what scientists have named, the big crunch as opposed to the big bang. This will then once again create the big bang as it falls into itself, and the universe will start over, and by this time different compositions of material will change the universe, this process will continue for "X" years, and as we know when something is reused over and over, it loses it's original composition, and eventually becomes null, just like chewing gum. Thus making the universe end because of the lack of materials in space.

I have a lot of time on my hands.

Answer 2

Of course, nobody knows. But there are theories. The most current one, based on the observation of the accelerating expansion of the universe, is the Big Freeze. All galaxies move away except for those in the same clutter like us and Andromeda. We'll end up in a big black hole that will eventually empty its energy so that what's left is particles with not enough proximity to form atoms that will continue expanding for ever.

Some think that it will end up in the Big Crunch, i.e. everything will move together again to form a new Big Bang.

Some think of the Steady State where nothing is changing or, perhaps, matter is lost and created, in an ever looping enclosed universe.

But the truth is: we don't know.

Answer 3

there are  diffrent theories....

the big crunch and the big rip are two of them...

in the big crunch, dark energy can no longer push the universe outwards, and it all comes flying back in, like a deflating balloon, and it's thought this creates a singularity, from which the big bang is reborn again, and so is the universe

the big rip, space just keeps expanding.. and at the same time stars have mostly all died and rebirthed smaller stars, incapabale of going super nova, thus no more stars are born... and the few stars that are left are red giants, producing minimal heat and the universe becomes even more cold and lifeless then it already is.... this continues, until eventually space is so vast, matter can't collect to build anything new... thus the universes is deviod of life and stars, with just a thin scattering of particles of what used to be us, planets, stars, and everything else that currently 'is'

Answer 4

No it could never end and here's why: It never had a beginning and it is continuously expanding at a faster rate. No projectile ever accelerates after it leaves it's source.

Our part of the universe may have started from an initial local  expansion but that doesn't mean there aren't other parts of the total universe also initiating from similar expansions or big bangs.

We can only observe light from about 13 to 15 billion light years away. (the jury is still out on the exact age of our part of the universe) That is the limit of our scope for now so that is the limit of our universe for now.

Answer 5

There are three ways that the universe ends...

1)  Big crunch, where everything is drawn back towards a singularity and matter as we know it "crunches" back up to a single point.

2)  The Universe continues to expand, and everything eventually cools off to a few degrees above absolute zero.  

3)  The universe continues to accelerate its expansion, and matter is torn apart from this.  

The end all be all is that we better hope that we aren't around for #1 or #3.  We might be able to to something about #2 if we continue to become technologicaly advanced.  But this will happen in a few billion years....the human race will most likely not be around at that time.

Answer 6

i had a theory

if something can start it can also end

i've tried to prove it wrong but i can't find anything that contradicsts it

Answer 7

Scientists say it will be one of these:

Big Freeze or Heat Death-The Big Freeze is a scenario under which continued expansion results in a universe that is too cold/hot to sustain life. It could, in the absence of dark energy, occur only under a flat or hyperbolic geometry.

Big Rip: Finite Lifespan-In the special case of phantom dark energy, which has even more negative pressure than a simple cosmological constant, the density of dark energy increases with time, causing the rate of acceleration to increase, leading to a steady increase in the Hubble constant. As a result, all material objects in the universe, starting with galaxies and eventually (in a finite time) all life forms, no matter how small, will disintegrate into unbound elementary particles and radiation, ripped apart by the phantom energy force and shooting apart from each other.

Big Crunch-The Big Crunch theory is a symmetric view of the ultimate fate of the universe. Just as the Big Bang started a cosmological expansion, this theory postulates that the average density of the universe is enough to stop its expansion and begin contracting. The end result is unknown; a simple extrapolation would have all the matter and space-time in the universe collapse into a dimensionless singularity, but at these scales unknown quantum effects need to be considered

Big Bounce-The Big Bounce is a theorized scientific model related to the creation of the known Universe. It derives from the oscillatory universe or cyclic repetition interpretation of the Big Bang where the first cosmological event was the result of the collapse of a previous universe.if the universe is closed, this theory would predict that once this universe collapses it will spawn another universe in an event similar to the Big Bang

Multiverse: no complete end-The multiverse hypothesis states that our universe is but one universe among infinite parallel universes, possibly with different physical laws. Whatever the ultimate fate of our universe may be, almost all parallel universes will have different fates.The multiverse as a whole may never end completely.

False vacuum-This has the potential to fundamentally alter our universe; in more audacious scenarios even the various physical constants could have different values, severely affecting the foundations of matter, energy, and spacetime. It is also possible that all structures will be destroyed instantaneously, without any forewarning.

Answer 8

Surely the universe as we know will end but not in our lifetime.Life on earth will surely stop to exist first than the end of the universe. We are on an expanding universe, imagine what will be the effect of great distance to gravity.

Answer 9

I think probably not the universe will end soon but the human race will. Because the aztecs predicted the earth will end on 12-21-12 and nostradamus's last prediction said "the newly elected dark one will lead the final battle" so im guessing thats Obama lol.

Answer 10

Implosion.The voids that are known as black holes will suck  everthing in,bringing an absolute end to existance.

Answer 11

i say no it wont end.

Answer 12

How and when is unknown.  Complete conjecture; totally guesses.  

There is one thing, though, that is pretty sure . . . .

you won't be here to know about it.
