is string theory true? explain your opinion.?

Answer 1

Maybe a couple hundred people even understand the thing.

And not two of them agree on the particulars.

What I've heard-- string theory requires 5,11, or 637 dimensions of space/time in order to work mathematically. Since we don't experience those dimensions, the theory has worked out a way to "hide them".

To me--this is problematic. Like a child caught in a lie, the theory is working too hard to hide inconvenient data.

But I am not a physicist. Just a guy who used to read Omni magazine...

Answer 2

First of all, if there ever was such thing as blind faith in science, string theory is it. Unlike other scientific theories which have ways to poke, prod and observe to test the evidence to support them, we scientists do not even have a theory on how we can ever test string theory. As such it should not be categorized by the scientific method as a theory, it should however still be categorized as a hypothesis. The only thing string theory has going for it is the math that has been proven accurate individually for the areas of quantum mechanics, theory of relativity and theory of gravity fit together perfectly as a complete string theory formula just like pieces of a puzzle. These pieces will not fit together in any other way as an all encompassing unified theory. The conundrum is that for string theory to be correct, parallel universes as well as a whole slew of other extremely bizarre never observed phenomena must exist. Some scientists believe that the vibrating strings of energy described in string theory is what people call god. Do I believe it? I don't know, there is not enough evidence for or against it to make a judgment. Is it possible? Maybe. Will mankind ever come close to being able to test string theory to prove it one way or another? I have no clue. BS Physics MS Quantum Mechanics PhD Nuclear Engineering Atheist

Answer 3

11 dimensional string theory, (and 26 dimensional M theory), has not produced anything.

It is possible that the extra 7 dimensions of space in string theory, (that are not perceived), are mathematical deception that first appeared with 5 dimensional Kaluza-Klein Theory.

String theory is possibly deception involving adding dimensions of space to the already existing 3 dimensions of space one dimension at a time at 90 degree angles to the previous dimension.

That string theory is possibly invalid is stated at the end of the wikipedia article on string theory.

Answer 4

nothing in science is true. thats not to say its not the best thing we have to learn about the world. a theory by defintion isnt truth. science is an ever evolving approximation of reality. we can never know if out understanding lacks some fundamental aspects. string theory may one day be pretty well supported, but it will always be a theory.

Answer 5

Determining the validity of a theory is not a matter of opinion. It is a matter of evidence. Period.

There is currently no evidence consistent with string theory that is also inconsistent with conventional particle theories.

Answer 6

string theory is outdated. there are 5 different kinds and scientists didn't like that. the more recent version is m-theory. its semi-popular, but its nowhere near proven. you cant prove m-theory because we cant interact with any other universes and the 11th dimensional membranes are too small for us to notice.

Answer 7

according to string theory in at least one parallel universe string theory is true.

Answer 8

The jury is still out on that.
Unfortunately, my math isn't good enough to make a decision. But then neither is that of 99.9999 % of the rest of the human race. I can handle General and Special Relativity, so I am not ashamed.

Answer 9

a very very good question to ask!!!!!!!
it could be true but no one has proved it completely like the one
theory of general relativity
grand unified theory

Answer 10

No one knows yet. It is still being examined and scientists are looking for more evidence that will verify it one way or the other.
