What about M-theory?

In my honest opinion, M-theory is total BS.

Your veiws on this universe sounds like the model of the hypothetical universe you posed in your first post.

But you can see where not all of contemporary science agrees, because m-theory does have a fairly strong group of supporters.

Well I definitely don't think the universe is infinitely big, and I only say that we don't know if the universe necessarily had a beginning.

They live in imaginary world. Science must rely on evidence, otherwise it's not science.

Oh come on, you're being a little hyperbolic.

Nice math pun. While we are on the subject of math, maybe vktr is right. I think one of the problems with quantum mechanicist is their reliance on higher math like Probablity and Statics. There is a difference between fact gathering from observing and predicting something on paper based on formulae.

Of course :) But have you read this book by Lee Smolin?

The Trouble With Physics: The Rise of String Theory, The Fall of a Science, and What Comes Next

Scroll down that page and look at the review by Peter Shor.

String theorists: We've got the Standard Model, and it works great, but it doesn't include gravity, and it doesn't explain lots of other stuff, like why all the elementary particles have the masses they do. We need a new, broader theory.

Nature: Here's a great new theory I can sell you. It combines quantum field theory and gravity, and there's only one adjustable parameter in it, so all you have to do is find the right value of that parameter, and the Standard Model will pop right out.

String theorists: We'll take it.

String theorists (some time later): Wait a minute, Nature, our new theory won't fit into our driveway. String theory has ten dimensions, and our driveway only has four.

Nature: I can sell you a Calabi-Yau manifold. These are really neat gadgets, and they'll fold up string theory into four dimensions, no problem.

String theorists: We'll take one of those as well, please.

Nature: Happy to help.

String theorists (some time later): Wait a minute, Nature, there's too many different ways to fold our Calabi-Yao manifold up. And it keeps trying to come unfolded. And string theory is only compatible with a negative cosmological constant, and we own a positive one.

Nature: No problem. Just let me tie this Calabi-Yao manifold up with some strings and branes, and maybe a little duct tape, and you'll be all set.

String theorists: But our beautiful new theory is so ugly now!

Nature: Ah! But the Anthropic Principle says that all the best theories are ugly.

String theorists: It does?

Nature: It does. And once you make it the fashion to be ugly, you'll ensure that other theories will never beat you in beauty contests.

String theorists: Hooray! Hooray! Look at our beautiful new theory.

^Haha, haven't read it but I'm intrigued.

-Head explodes-

.... Yes? ._.
