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.
. . . witty, and profound, but the announcement that the free bagels and donuts we get every Friday have arrived.
Just think, if only one percent of those billions of new universes repeat our time-stream, this joyous moment will be repeated . . .
whoa, they maple bars this morning. I'm out of here. Priorities . . .

Just ask the good Jedi how they feel about "Balance" now...
... is there something somewhere else blowing?
And no, that wasn't a Spaceballs reference!
I only look human.
My mother is a halfling and my dad is an ogre, so that makes me an Ogreling
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.
"Things are more moderner than before- bigger, and yet smaller- it's computers-- San Dimas High School football RULES!"
I'm a physics teacher currently teaching about the Big Bang and possible ends of the Universe. I'm just wondering if there are any research physicists in the room who could tell me which theory of the end of the Universe has the most physical evidence to support it at the current time.
Thank you,

You frequently get the question "Why is the universe {whatever}?" or "In order to support human life, the universe had to be {whatever}."
This is frequently used to support the idea of divine intervention.
If you ask such a question or make such an observation, you have to remember:
The fact that we are here to observe it greatly restricts the possibilities, so what seems like "long odds" isn't long odds after all.
To put it another way:
If you play in the Superbowl and win, and your friends congratulate you, you don't say "What are the odds of my friends congratulating me for winning the Superbowl? There are 300,000,000 million Americans and only a few dozen have friends who congratulated them for winning the 2007 Super Bowl. That is rare, this is proof of divine intervention in my life."
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
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.
Intelligent Design is not as good a theory as any, as you say, unless you think theory means "gosh all this science is hard stuff! Let's throw up our hands in reverent awe and say that some unknowable entity poofed us into existence. Alright, time for lunch."
> The model could solve the mystery of why our early universe was surprisingly well ordered.
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...
I don't know the meaning of the word 'don't' - J
Because physicists dont look shit up on WordNet.
The word delegate means different things to a security guard at the UN, and a C# programmer.
I don't need no instructions to know how to rock!!!!
See, that's why I like the Torah.
It was originally written in hebrew. Guess what? It's still read in hebrew.
I may not follow the jewish religion spiritually or even traditionally...but I still feel we have the holy text that is closest to what how it was originally written...
That doesn't explain why using electricity on shabbat is considered work but walking five miles because you aren't supposed to drive is NOT considered work. Fuck that.

I see no problem with a fourth dimension expanding relative to the three spatial dimensions.
Here's how we can define it:
"The fourth dimension is expanding rleative to the three spatial dimensions."
What laws or axioms or postulates has the above statement violated?
None that I can see.
What the author seems to be saying is that time is an emergent property of this underlying physical reality, which they then use to unify seemingly disparate physical phenomena.
"The fourth dimension is expanding rleative to the three spatial dimensions."
This would explain why everything propagates through space-time at the velocity c--this never changes.
