string theory?

Question

String theory predicts all material in the galaxy from the smallest subatomic particle to the grandest star is made of strings. The string vibrate like music note giving atoms their uniqueness. Most physicist don't accept this theory since their are five formulas. The formulas are quite similar. Is it possible this five formula represent five equally similar worlds us ours; but except for a small insignificant difference like a parallel world.

Answer 1

Its possible but again... just a theory.

Answer 2

The M-theory, or Master Theory, is the unifying string theory that suggests the existence of an integrated functionality of the five, and that all of the different string theories may now be thought of as different limits of a single underlying theory. It is representative of the connectness AND the duality of the ENTIRE universe.

The reason scientists have yet to accept string theory is that it remains to be confirmed. No version of string theory has yet made an experimentally verified prediction that differs from those made by other theories. In this sense, it is not a proper PHYSICAL theory. It possesses many features of mathematical interest and may yet become important in our understanding of the universe, but it requires further developments before it is accepted or discarded. Since string theory may not be tested in the foreseeable future, some scientists have asked if it even deserves to be called a scientific theory: it is not falsifiable in the sense of Popper (see Karl Popper).

There is nothing that alludes to five separate, equally similar worlds as ours among the theories--this is a misinterpretation on your part. And if there were a parellel world, the difference would not be small nor insignificant.

(an excerpt from the encyclopedia)

Prior to M-theory, strings were thought to be the single fundamental constituent of the universe, according to string theory. When M-theory unified the five superstring theories, another fundamental ingredient was added to the makeup of the universe - membranes. Like the tenth spacial dimension, the approximate equations in the original five superstring models proved too weak to reveal membranes. A membrane, or brane, is a multidimensional object, usually called a p-brane, with p referring to its spacial dimensional makeup. The p-branes can be any number of spacial dimensions ranging from zero to nine.

(The inclusion of p-branes does not render previous work in string theory wrong on account of not taking note of these p-branes. P-branes are much more massive ("heavier") than strings, and when all higher dimensional p-branes are much more massive than strings, they can be ignored, as researchers had done unknowingly in the 1970s.)

Answer 3

An intelligent question to be asked - no doubt, but the answer in not known, the theory is just that - a theory - it still hasn't been proved to a reasonable doubt to physicists. Or, the class is still is session.

To get into the mathematics is beyond such a forum such as this, but explaination of SOME of the particals postulated have been should to be POSSIBLE, although we, as scientist, have still not proven the existence of any of them.

To speak of strings (in string theory), we mustn't forget that we are actually dealing with particals and the hardest of them to grasp is the Quantum Gravitron, and partical with no mass but with two units of spin.

Let's let the Theoretical Physicists figure this one out - because my knowledge is about spent at this point. Never-the-less it is an interesting theory - rooted way back in time by that old genius Pythagoras.

Answer 4

I read "the elegant universe" and started out impressed, because it said everything could be explained so much more simply if we didn't need to understand that there are photons, and neutrons and protons and electrons and muons and quarks, etc...
But then, I had to learn in string theory about curled-up dimensions, not one of them but 11 or so!
Anyway, I don't find it an easier explanation so I'm giving up. There is a nice NOVA on-line set of videos based on the book that I may try when I get the energy up to think about it again:

Answer 5

Ed Whitten has fused the original 5 theories into one, and given the entire field credibility. I seriously doubt any of the theorized parallel universes obey the laws of physics as we know them in this universe. An interesting subject with fuel enough for another generation of physicist.

Answer 6

11 dimensional string theory has not produced anything.

It is possible that the 7 dimensions of space that are not perceived are mathematical deception, and therefore string theory is a theory of nothing, as you will find if you read the wikipedia article on string theory all the way to the end.
