Saving civilization from the end of the universe

[everman]

I just read an interesting article about how eventually it looks like the universe is going to end in a kind of great freeze. The temp of everything will be absolute zero thus intelligent life ceases to exist. The only way to survive would be to escape to a parallel universe.

Theoretically "our universe may be a membrane floating in 11-dimensional hyperspace, while we remain oblivious of the parallel universes hovering nearby." A Type III Civilization (the highest level proposed by Nikolai Kardashev), may posses the technology to do this.

Several ways to create a wormhole are proposed, including a ten light-years long particle accelerator :Q


It seems like it would be more likely to create or find very small wormholes (the size of molecules). One idea is to send over nano-machines to re-create everything in the new universe.

The craziest idea of all was to simply create your own universe...


Very interesting stuff overall, considering we can barely leave our own solar system or even planet. But I guess that's what it all comes down to if parallel universes really do exist (and a means of getting to them which I assume is yes if they do exist).

if it were up to me i wouldn't want to save over half the people on this planet.

Check this out:

Good Book

It is written by a phycist who considers this very question.It changed my life at the age of 13.

Apparently, at the end of Akira, Akira creates a new universe. I think the Japanese are holding out on this technology until the deep freeze strikes, then they'll sell it to the highest bidder.

I don't think humans have to worry about such things. Our species will be long extinct by then. Heck I doubt that any civilization from the planet earth is going to make it permenantly out of the solar system before the sun goes out in 3 billion years or so.

There's the idea that our own perceptions of the universe are actually our own universes.

I'm not that worried about the universe freezing over. I'll probably be dead by then

It's absolutely true! Infact, they're using this technology in the Nintendo "Revolution" console. That's innovation for ya.

It doesn't really matter...the world is going to end in 2012 anyway...just ask the Mayans :shocked:

I heard about that 2012 thing and its sited in a lot of places.But, will it happen?Only >8 years until we know!

That's if you subscribed to the Big Bang theory. If you don't, you'll believe that matter is infinite (which I believe in, as we can observe matter recycling itself). A dying star becomes a nebula that builds new stars. Stars form into galaxies. Galaxies into clusters. Clusters into Super clusters. Eventually space won't be space anymore, but a "living" plasma (which might just be the Big Bang in the first place).

We'll probably never know, because as a species, we'll be long gone to appreciate the idea.

Going to have to find a good, empty Universe though. I don't know how it would go if we had several hundred thousand billion civilizations pouring into this one from loads of wormholes, escaping their doomed Universe.

Professor Farnsworth did this - created a whole bunch of Universes too. Eventually, we wound up with a box in this Universe that contained our own Universe.




All I know is, it's going to be a damned long time (5 billion years, thereabouts) until our sun transistions into a white dwarf, toasting the inner three planets in the process. And it's going to be a LOT longer until anyone starts to notice the deep freeze from the Universe's expansion.

This dark energy they propose....it's almost like anti-energy. There was an imbalance of it at the Big Bang - the explosion annhialated much of the antienergy, but not all of it. Just like a lot of antimatter formed, but there was just more matter than there was antimatter, so we're stuck with it today. Just a thought.

That's if you subscribed to the Big Bang theory. If you don't, you'll believe that matter is infinite (which I believe in, as we can observe matter recycling itself). A dying star becomes a nebula that builds new stars. Stars form into galaxies. Galaxies into clusters. Clusters into Super clusters. Eventually space won't be space anymore, but a "living" plasma (which might just be the Big Bang in the first place).

You can't just create matter out of nowhere, save for the singularities like the Big Bang. And even that might have just been a conversion of energy from the impact of two branes.
The dying star becomes a nebula, but only a small planetary nebula. It won't form any new stars. It just dissipates; a star farting in the interstellar wind. "Puff" and then it's gone, save the little white dwarf that's left over, and the frozen planets nearby.
However, this gas can coalesce into larger nebulas, which can create new stars, but you won't get more than what you put in. If it took 1000 stars to make one big nebula, you won't get 1000 new stars out of it. A lot of energy has been lost, emitted into the emptiness of space, and a lot of matter was just blown away. So yes, matter does recycle itself, but nothing is 100% efficient. Some matter is even converted into energy - black holes do that really well, yielding X-rays and gamma radiation. And that energy is headed to the outer fringes of the Universe, with very little to stop it from just leaving.

From the article:

Relativity theory rules the world of the very large?of black holes and expanding universes.

That's something I don't think is right. Standard relativity breaks down in singularities, which include black holes and the site of the Big Bang.

Fascinating article. Either way, there's going to be a loooong time to ponder these things, and I doubt that this species will be around to find the answers. Not that I'm saying that we'll wipe ourselves out, though sometimes that seems like the most probable thing, but that we'll become some different species. At some point in the distant future, we'll have to redefine "homo sapien," or what it is to be human, and if that distinction really does matter.

 

[Chaotic42]

Man, imagine where we'll be in hundreds of billions of years when that will be a concern. Just think about how far we've come in the last 100 years.

 

[Polishwonder74]

Just getting your feet wet in theoretical physics? Hyperspace by Michio Kaku helped me a lot back in the day.

 

[joe4324]

do you think Duke Nukem Forever will be out by then?





OMG sorry I couldnt resist!!!!!!


I thought the universe was constanty expanding outward and outward, and that eventually it could poteintially 'sling' back like a rubberband, into a singularity then POP, here we go again

 

[Pr0d1gy]

I sure hope my son gets to see that one!!! lol

What you say is true for now. The problem is hydrogen. You get energy in converting hydrogen->helium. But they are not making any more hydrogen. When it is all used up, stars will have no more fuel.

 

[thelostjs]

ok for the record im 17...
fusion is putting together 2 small atoms hydrogen = h /helium = he

h+h=he simple as that
fission is breaking apart one large into 1 less large and one small
i dont feel like finding the actual "formula" for this
but it stands to reason that you can get many atoms of hydrogen out of one atom of something heavy...

and stars can fuse helium as well as hydrogen i believe this is the red giant stage..
im gonna go read up on this and post later

She may be as ignorant on this topic as she is on the topic of biology.

Impressive.

Fission doesn't really work that way. We don't end up with a bunch of hydrogen.

And stars can fuse a lot more than just hydrogen and helium. Stars eventually end up with a core of Iron--that's the basic fusion limit of a star. Anything above that needs a supernova.

right, but the point was that this isnt true --->

What you say is true for now. The problem is hydrogen. You get energy in converting hydrogen->helium. But they are not making any more hydrogen. When it is all used up, stars will have no more fuel.

for that star maybe but in my book it says that 98% of the universe is made up expressly of hydrogen and helium

Haha! Werd... we screw up our own planet enough. Now we want to screw up a parellel universe as well?

Erm...and your point? We're not talking about anything that's going to be happening soon. We're not talking about billions of years--that's much too small a time span. Nor are we talking about ever having a time when hydrogen is not the most plentiful element--it'll just be spread out enough to not be able to coalesce into stars.

Try this wikipedia link for an idea on the time frame involved.
