New Universes Will be Born from Ours
David Shiga writes "What gruesome fate awaits our universe? Some physicists have argued that it is doomed to be ripped apart by runaway dark energy, while others think it is bouncing through an endless series of big bangs and big crunches. Now, scientists have combined these two ideas to create another option, in which our universe ultimately shatters into billions of pieces. Each shard would then subsequently grow into a whole new universe. The model could solve the mystery of why our early universe was surprisingly well ordered."
Now it sounds like these guys aren't even trying anymore. I could've sworn I saw this in an episode of Star Trek.

Just ask the good Jedi how they feel about "Balance" now...
Baby come back!! No more dark matter - I promise you a Big Bang this time!
I propose that the universe is actually a cheap science kit awaiting purchase on the shelf of a hyper-dimensional Toys-R-Us. I could probably prove it too if I had the funding...
Nothing witty
We'll stick around to stay in our little galaxy's lives, as we want to pass on our knowledge and provide care for them. That and the threat of paying child support.
In Soviet Russia, dots slash you!
There has been a lot of research showing that Black Holes themselves are essentially fundamental particles. Coupled with (even if string theory isn't true the fundamental particle geometry is interesting) two concepts of measuring distance. Such that when one passes the Plank Length the 'easy' way of measuring distance becomes hard and measures the reciprocal instead, while the previous hard way becomes easy. Then throw into all of this the notion that we are all moving through space-time at constant velocity (light speed - this is why when you travel faster through space time slows down. so no-one really understands what time is, or how many dimensions (of 11, say) are time, or whether they are essentially different from space, mathematically, physically or philosophically.
So yeah, i'm just about willing to believe anything right now.
Prominent bizarro physicists believe the new universe will be inverse of our own, controlled by the indigent, and known as the hobo-verse. This new hobo-verse will be controlled by a singular omnipotent box car hobo named "Klackity Klack." Also, it will smell like pee.

Right now, the theory with the most evidence in its favor is the theory which includes a dark energy described by Einstein's cosmological constant. In that theory, the universe's expansion will continue to accelerate forever, although not at such a great rate that there is a "Big Rip" which tears atoms apart. That is the "heat death" scenario, in which the universe lasts forever and runs down until nothing much is going on. Because of the accelerating expansion, we will see fewer and fewer distant galaxies as time goes on, because they will accelerate away from us faster than light can reach us. Ultimately we will only see a few local galaxies in the cluster in which we are bound.
This scenario is explored in more detail here.
However, it's possible that the dark energy is dynamical instead of constant, and so the expansion of the universe could accelerate or possibly even reverse and decelerate. With enough deceleration, a Big Crunch is still feasible. There are also the scenarios in which our universe spawns new "universes", such as the one discussed here.
When all you have is a hammer, everything looks like a skull.
I think the work being referred to may be in this paper, in which the universes are "causal patches" which are disconnected from each other causally by the Big Rip.

Not really - you've just pushed the problem back one level. Where did the well-ordered universe shards that made this universe come from? It can't be "turtles all the way down"
If you define a different universe as being physically distinct from ours, then yes;
If parts of our universe started out in the same singularity as us but are now outside of our light-cone, then they are in effect physically separate from us, so that places them in a different universe, doesn't it? If they are outside our light-cone, and can no longer affect us, then they are not in our universe anymore but since they still exist, I think you have to consider them as being in a different universe.
Of course it means they have to be outside of our entire universe's light-cone...
