How crazy I am to think this of the universe?

[SSSnail]

Alright, so supposedly the universe came from a singularity of immense density, exploded. Fast forward 13 or so billion light years, we have what we have today, with stuffs and galaxies.

Now, each galaxy is supposedly revolving around a giant black hole. Would it be logical to say that eventually everything will come back to be a singularity of immense density?

Discuss.

 

[Atomic Playboy]

Yes.

mhm

 

[venkman]

No one has ever though of that before. Give the man a nobel prize.

 

[40Hands]

We all is gonna die?!?! I'm sure God is cooking up a somethin' for us.

Let's make it a Royal prize, just for him.

crazy you are to think that about the universe.

gak! That is the last time I trust firefox spell check.

lol that's what Iheard too, that the universe could possibly be contracting and expanding all the time. Nobel prize, STAT!

true, ff spellcheck needs a huge overall, like, badly....

Hawking radiation, bitches. Read it, love it, live it -- in summary, no.

 

[RESmonkey]

That would take a long time, but everything is drifting away from everything else...so, the universe would probably drift away forever.

 

[MikeyLSU]

yes and what will really blow your mind is the idea that this has happened many times before.

Universe explodes(big bang)

Universe implodes back on itself

Rinse and repeat..


Maybe it has happened a billion times already, maybe humans have existed a few times then went extinct during the imploding of the universe...

What are the chances of everything reoccuring? Wouldn't things be different everytime?

Or, if there is no difference between each explosion (every single particle does what it's supposed to), then everything reoccurs in the same spot...over and over...

Hmm...

 

[AmpedSilence]

Yes, It's called "The Big Crunch"

This was a theory a while ago, but it has since been proven that the universe is still expanding - in which case it is less likely to implode back on itself than it is to pop like a balloon.

So how long is a light year compared to a normal one?

in summary, no... until it's disproven by some other discovery.

frankly, i like blindly believing in the big crunch. makes me feel like i have something in common with all of those christians.

That's the great thing; it's the same length, but only half the calories. Now you can age without feeling guilty!

 

[dainthomas]

The universe will continue accelerating outward until all the stars burn out and even the black holes evaporate, leaving only infinite cold nothingness and death.

But Jesus will fly down from heaven and take all true Christians back with him WAY before all that!

 

[Jeff7]

Maybe. There's also "dark energy" - they don't quite know what exactly it is, maybe it's some property inherent to space itself. But the expansion appears to be accelerating.

Maybe it's a repulsive force that is generally weak, but when it's not overcome by gravity, it can be rather powerful.


So if not the "Big Crunch," then we'd be looking at "Heat Death." Everything with a temperature above absolute zero produces electromagnetic radiation. Think about what metal does when it glows red-hot. That's just because the temperature increased the frequency of the EM output enough such that it entered our visual spectrum.

But since everything is radiating energy out into empty space, eventually everything is going to cool off to nearly absolute zero. In a LONG time, elements will undergo radioactive decay, and even protons will likely decay too, though they've got an insanely long (theorized) half-life, something like 10^36 or 10^38 years, which is much older than the age of the Universe.

Pretty well the same thing you'd expect of an explosion on Earth. Big, violent eruption of energy, followed by an expanding shock wave, full of turbulent matter and energy behind the wave. Eventually, it all dissipates and cools.

 

[antyler]

no.

 

[Arkaign]

Mmm. entropy.

The drifting away part is tied in with the Heat Death.

And yeah, Proton Decay would leave everything gone except subatomic particles floating here and there...unless they somehow decay?
