Multiverse Means Universe Ends In 5 Billion Years?

The clock is ticking. We've got just 5 billion years to figure out out to break out of this pocket in the multiverse into a universe with more time left to run. The last restaurant at the end of the universe will be sitting its final guests just billion years hence. That restaurant should be located at the multiverse space port for a last meal before we escape.

"We could run into the end of time," Ben Freivogel tells a seminar at the Massachusetts Institute of Technology in Cambridge. Several colleagues seem nonplussed, and one Nobel laureate looks downright exasperated. "I'm aware that this sounds like a crazy conclusion," Freivogel admits, generating a round of what sounds like relieved laughter. But perhaps their relief is short-lived.

If there is an infinite number of universes in the multiverse then doesn't this mean that a universe identical to this one has already come into existence and winked out again? Didn't Kara Thrace say something to that affect too? In how many universes did she say it? Maybe there's a universe where she said it for real too.

Of course, if identical universe recur then similar universes probably recur as well. In a trip to some similar universe what do you most want to find is different?

Multiverse is quantum baloney, filled with inedible theories about an infinite variety of possible outcomes. When it comes to defining branching and its cause, there is mumbling about quantum this and that, as if invoking the counterintuitiveness of quantum physics obviates rational explanation. Stuff and nonsense, it is.

Jim - it would be easier to argue your claim if you'd make one. Waving your hands like a creationist is not an argument.

There's vociferous disagreement among physicists about various possible implications of QM, and the debate is quite lively. But if you want to join the fun, it requires a bit more than a hearty bah-humbug.

I bet one multiverse has pink unicorns

What I don't like about the multiverse theory is there are an infinite number of universes in which I have just won the lottery.

But never this one.

lol xd, you put that so funny.

I would most like to visit a universe in which my particular phenotype is not a minority one!

(then we would proceed to conquer the rest of the 'verse in a co-operative, collective, manner)

THERE CAN BE ONLY ONE!

I have already witnessed the end of time. The battery in my wall clock ran down. The clock stopped. As far as I can tell from looking at that clock, time in my bedroom has stopped.

TheBigHenry said at September 29, 2010 9:40 PM:

Your clock may have stopped, Andrew, but it still reports the correct time twice per day. So time, in your bedroom, marches on, albeit in 12-hour leaps.

I'd say his statistical reasoning was lame, but that would require acknowledging it as "reasoning". There may be reasons to think that the universe is going to come to an end in a few billion years, but statistics being inapplicable to infinite sample sizes ain't one of them.

I want to go to a universe where liberalism is compatible with human nature.

Stop laughing. You know it'd be sweet.

Randall Parker said at October 1, 2010 8:40 PM:

Lono,

If you are a majority then there's nothing special about you. Do you really want to experience such a loss in status?

Aspirant,

Why would I want everyone to be as smart as me? I do not have a strong instinctual desire for equality. So such a universe would not be sweet to me.

Your problem is you have the instinctual desire for equality combined with a realistic view of human nature. That's got to be painful. My advice; Do not adopt delusion to lessen the pain. Find a better solution.

Lono said at October 4, 2010 9:06 AM:

Randall,

If the majority of people on Earth were strong, tall, highly symmetrical, exceedingly intelligent, generously empathetic, cooperative, and implicitly altruistic then it would be a frikkin' insane paradise here.

It might be best if they weren't all narcissistic megalomaniacs as well - but I honestly donít think that would get in the way of progress.

What good is it to be in the minority? At best I can simply attempt to impose my benevolent will on the rest of humanity until the day when I have the technology to remake our (or another) species in my image.

I'll make do with what I have - but I assumed you were asking us to consider a best case scenario.
