    M theory Theory
Click For Summary
The discussion centers on the relationship between F-theory and M-theory, particularly exploring the implications of F-theory's concept of two time dimensions. Participants express skepticism about the feasibility of two time dimensions, questioning how this would affect entropy and time travel. Some argue that if two time dimensions exist, it could allow for simultaneous existence of past and future, potentially resolving paradoxes related to time travel. However, others counter that this idea contradicts the definition of the future as something that has not yet occurred. The conversation also touches on entropy, with participants debating whether it can increase in two directions simultaneously. Ultimately, the discussion highlights the complexities and speculative nature of these theoretical frameworks in understanding time and entropy within the universe.

Mentat, assume the universe is unbalanced=disorderly. If it is unbalanced, then it could be both at onece. That's what makes it disorderly.

Are you saying that, if it is disorderly, then it can be orderly?

I assume that by "two time dimensions" they mean two timelike dimensions, in the sense that the radial dimension of a black hole is timelike (it forces you to move forward, never backward.) I doubt it's much of anything to worry about and more than likely has nothing to do with entropy.

No, not orderly as in completely orderly. What I mean is 'portions' could be orderly, and others wouldn't be orderly. And that's what makes it disorderly, disproportional. BUT, don't take what I'm saying as factual; I'm speculating at the top of my head.

Majin, whether it's altogether disorderly or orderderly is not really important. What I'm saying is that if it is getting more disorderly then it is getting less and less orderly, isn't that right?

Precisely!

But what does 'disorder' imply about the universe? Chaos?

Then the idea of entropy's "increasing in more than one direction" is nonsensical, is it not?

I guess.

Alas, there are quite a few people who hold to the idea of two time dimensions, and so there may be some good reasoning behind it. Don't just take my reasoning, learn as much as you can about them (if your interested) and make your own conclusion.
