The Theory of Parallel Universe - Documentary

[longship]

19. Strings are not a theory.

It has no supporting evidence. As far as I am concerned it is mathematical legerdemain.

All the advances in theoretical physics for the last several decades -- since the 1930's -- have been in quantum field theory, the standard model, the most accurate and successful theory ever. (Well, that plus relativity.)

What have strings added to this dialog? Not much beyond mathematical techniques (which should always be valued). Strings are basically untestable, no matter what its adherents claim. If their claim is true that it is testable, there certainly are not many jumping into the fray to do the requisite work. This after decades of which I predict will be fruitless.

It might be true, but I wouldn't put much money on it.

Note that I am not against people studying the string conjecture. However, not to the exclusion of more demonstrably productive areas.

My best to you.

And I have been aware of the many worlds hypothesis for decades. So far, no evidence for that either.
