Multiverse Theories

mattityahu · 28-May-2009, 05:16 PM (17:16)

What are you opinions on Multiverse theories?

Are they a part of science?
Is it reasonable to believe in other universes?
Which theory (if any) do you prefer?
Will such theories ever be testable?

I would like to think they existed, but in a practical way it's irrelevant to me and life.

Theorising about them? Yes. Like any theoretical maths. You never know what might eventuate.

Yes. IMvHO.

Me personally? I've got no preferences in this area.

Most probably, no. Some steps may be testable. OTOH, who can say?

Perhaps I should have added "...and why are you of this opinion?" as this will hopefully lead into a deeper discussion as to the implications of whether these theories are likely to be true or not.

Personally, I'm not convinced either way on the issue (which is why I wanted to ask you all

). But there are definitely huge implications about whether our universe and human life really is 'special' (as my intuition seems to tell me), about the significance of so-called 'fine-tuning', and so on.

Quick Q: I guess I got my terminology mixed, but are these theories or hypotheses?

mattityahu · 29-May-2009, 09:16 AM (09:16)

They are theories in the sense of maths, but hypotheses in the sense of science, so they're pretty interchangeable at the moment until they have some evidence to work on.

Ah I (sorta)* see.

*I'm taking a math course, and an essay they gave us went over hypotheses and theories in math, so, since I skimmed it, it rings a bell in the depths of my memory.

"Hypothesis" is only really used in statistics, and is something you apply a statistical test to; in pure maths "conjecture" is the word used for an unproven statement (that's not an axiom). A mathematical theory is a particular axiomatic system (or sub-branch of an axiomatic system) such as set theory, number theory, etc.

Have you thought much about multiverse theories, Fizzle?

Ah, clearer, I think, thanks.

Well, not really. It's kind of irrelevant. I mean, interesting, as all such theories are, but I don't think about it much before something far more "close" drives it off.

atheist of peace · 30-May-2009, 02:53 AM (02:53)

Fizzle what do you mean by, "something far more "close" drives it off," especially the, " something far more "close," part . Could you explain.

Closer to my life, as in stuff that affects it (i.e. friends, homework, college*,etc) and this stuff tends to take my mind off of things that don't (multiverse or universe makes no difference; I'll still be the same guy either way, with all the problems, memories,etc.)

*I can say college now
