?String theory.....provable or disprovable?

Question

are there strings vibating away in there and what about the eleventh dimention?

Answer 1

As of now, neither provable or disprovable. We would need instruments of many factors higher precision than we currently have in order to have a hope of "finding" a string. However, the reason people find it a good theory is it MATHEMATCIALLY MAKES SENSE as long as there are somewhere from 9-13 dimensions +time. Hard to believe, yes, but it explains why gravity is so weak compared to the other universal forces.

Answer 2

I read that it is losing some of its appeal lately in the crazy world of the small and cosmic. Personally I am still trying to get around five dimensions let alone ten or your eleventh. I did see a good explanation on the web the other day, but still..... Is it provable? Damned if I know. It seems no-one can disprove it at this time although that is no reason to assume anything. Frankly I don't like it all that much, but I am still arguing against the Big Bang, so what do I know.
Personally I am happy to believe it (the universe) is all just one big ball of nothing. It is the only thing that makes sense to me.
If you do work it out - let me know won't you.........

Answer 3

The problem with String Theory is that it works mathematically, but it requires the existience of many dimensions to do so. The question is whether such dimensions actually exist in reality. Theoretical physicists are uncomfortable with the idea that they can reach a solution only by arbitrarily adding dimensions into the equation.

The counter argument is that, if the theory explains a lot what we see, or deduce, about time and matter, and it needs 10 or so dimensions to work, then there must be 10 dimensions!

Certainly neither provable nor disprovable at present, but string-universe is theoretically possible.

Answer 4

The simple answer is yes, radio waves for example. You can't see them, touch them or hear them but you know they exist as otherwise nothing would come from your radio. These exist in a dimension beyond the sight of human's 3d capabilities. Particle generators are being used to try to create cosmic strings. The theory is that our universe was the result of a collision between two cosmic strings and that the particles, planets etc left in our universe was effectively dust ripped from each string. This doesn't explain gravity though which is a flaw with string theory, however, by creating a big bang in a particle accelerator it is hoped that a graviton will be created then disappear and will prove string theory by its absence.

Answer 5

String theory is completely speculative. It certainly isn't provable, in the sense that it can concretely support the idea of multiple dimensions. It does allow (if it could be proven) for multiple (additional) dimensions.

But it doesn't necessitate that they exist. So string theory could be completely legitimate and there could still at the same time be no other universes, and no extra dimensions we don't know about.

It wouldn't prove anything, but it itself hasn't been proven yet. It probably never will be completely proven because before you can prove something you have to start with starting assumptions, which aren't proven themselves. You start by assuming things that aren't themselves proven (and can't be).

Answer 6

I do not subscribe to strings.

It doesnt sound right and it is completely way off beautiful.

Nature and the universe works on spheres, and it depends on how you describe a sphere that matters.

The surface is one dimensional 1 dimension is always beautiful in nature.

but the volume is 3 dimensional, 4 with time.

We are looking at how we get from energy to mass.
e=mc²

If you use more dimensions you can twist things around a little more. But you must identify what the dimensions are.

Answer 7

The same theories that say they exist also say they are so indescribably small that by no means could they ever be investigated. Well, no known means.

However, with the M-theory version (at least) strings can take very high energies, which would make them observable. (Becomes 'branes' if you get high enough (if memory serves) which are more-than-one-dimensional strings)

Answer 8

Not provable yet but it's a good theory, I thought there were 14 dimensions though.

Answer 9

How do you're making a cello sound appropriate? sell it and purchase a violin. A violinist says to his spouse, "Oh, infant, i can play you basically like my violin." His spouse replies, "i might extremely have you ever play me like a harmonica!" A harp is a nude piano. Johnny comes residing house from college, and says to his mom, "Mommy, I discovered the alphabet at present! something of the class snarled around F, yet I made all of it the way by using!" Johnny's mom says, "very stable, son. this is on account which you're a violist." Johnny comes residing house day after at present and screams, "Mommy, Mommy, I counted to a hundred at present! everybody else could not get previous 60, yet I made all of it a thank you to a hundred!" And his mom says, "impressive. this is on account which you're a violist." day after at present, Johnny comes residing house and says, "Mommy, the instructor measured everybody's top in college at present, and that i grew to become into taller than everybody. Is that 'reason i'm a violist?" His mom shakes her head and says, "No, honey; this is on account which you're twenty-six."

Answer 10

I think we might need a bluring of the edges between spirituality and science to answer this one properly. We havnt advanced enough just yet.
