Grab your yardstick for the multiverse

Apparently, measuring the multiverse is harder than you might think. You don't just go down to Portal Corps and say, "just chuck me over that Dark Energy Scanner would you?" In fact, scientists (they don't even realise the word should have an exclamation mark) don't even like the idea of a multiverse, because they couldn't figure out how to measure it and that might have been a problem.

Luckily, some nice person has figured it out:

The comment at the top of page two saying that the entire universe could just collapse any time it likes into a lower energy state is a bit of a downer, but there you go, Portal Corps could have a future afterall.

(I'll leave out my rant about scientists disliking theories because they don't agree with how they think things should be. Save that for a later date. )

Very interesting. I have to ask though, because now I'm curious - why did you post this in the roleplaying section?

There are other sections of the boards?

The issues of alternate universes and multiverses comes up most in roleplaying? :P

Several of my characters have interactions with such, either from being power-hungry, socially minded scientists (Give them a wave, Zortel!), a fixed point in the fabric of time and space with a robotic body built around it (Take a bow, Number Nine!), a dimension hopping tourist with a sweet hat and nice boots (Lady Miller, you go girl!) and so on. :P

While the real answer is Zortel's, I'd have to go with Omy's one.

Well, luckily science is a self-correcting process so, in the long run, personal opinions of specific scientists on how the universe should be don't matter a jot. Einstein, even though he was instrumental in laying its foundations, didn't like quantum theory but, in the end, it didn't matter.

Regardless, this was a very interesting article you've pointed to. I especially like how Bousso's causal patch measure unexpectedly ties together with boundery conditions for a multiverse giving us a whole set of predictions we can actually test. Which has been lacking in theoretical physics as of late.
