Theoretically, if a particle is accelerated beyond the speed of light would it hypothetically "jump dimensions?" Would it disintegrate, or become something else entirely?

No, current accellerators can't support M theory, but in the near future they will, hopefully.

With reagards to faster than light travel, according to current theories, infinite force would be needed to accellerate any slower than light object to faster than light. So we think that that would be impossible.

Let's assume for a minute, though, that we could accellerate something, say an electron, faster than light. It would cross the "time barrier" and begin to travel backwards in time. As a particle (from rest) goes faster and faster, it's perception of time slows down. When (and if) it hits the speed of light, time ceases to exist for it. And when (and if again) it begins to go faster than light, it would travel backwards in time, very very fast. As it went faster still, it would begin to travel more slowly backwards in time.

An electron travelling backwards in time, it turns out, is the same as a positron. So to answer your question, if an electron were going faster than light, it would become a positron. The same is true for any other particle, it will become its respective antiparticle. Richard Feynman was the first to propose this idea. He actually went so far as to suggest that all the electrons and positrons in the universe are actually just one single electron, travelling both forward and backwards in time a great number of times!

theoretically you can't accelerate a particle beyond the speed of light because of the equation e=mc2 (squared). as you approach the speed of light the mass of the particle would seem to increase causing more and more energy required to be put into the particle to accelerate it further. evetually you would not have enough energy to accelerate the particle to the speed of light because its mass would become infinite (more or less). also dont forget the fact that some people believe that the speed of light is the fastest that anything can go and some think its impossible to go faster but thats theoretically speaking. hypothetically, if you were to accelerate a particle to or beyond the speed of light, there's no real way of telling what would happen. time would stop relative to that particle and most likely would disintegrate into its basic parts under the stress

The M theory is an extension of the string theory and was proposed by Ed Witten, a professor at the Institute for Advanced Study in Princeton, NJ. The string theory proposes that EVERYTHING in our universe is composed of tiny "strings" of energy that vibrate at different rates and all matter in the universe can be composed by different combinations of these vibrating strings. The "string theory" as it was presented several decades ago came close to explaining all the forces known to us in the universe but at a rather severe price. The price was that there would have to be as many as 20 dimensions and 5 or more different string theories. Ed Witten proposed a new way to look at the problem of multiple string theories during a lecture that he was giving on the topic. Instead of viewing the many different equations of string theory as different theories, Ed proposed that all of the various string theory equations were merely different views or perspectives of the same theory, which he called the M theory.

To answer your question, according to my limited understanding of particle physics and Einstein's special theory of relativity, E=Mc2, a particle such as an alpha particle, electron, quark, or even an antiparticle accelerated to near the speed of light would experience an increase in mass and become pure energy or a force carrier such as a photon/antiphoton (Electroweak force) or a gluon/antigluon (residual strong force) or perhaps even the proposed but as yet undiscovered gravitron/antigraviton force carrier as a result of the addition of momentum energy and the conservation of mass/energy would be preserved. This tremendous amount of energy would quickly decay into other particles thus conserving the energy/mass/momentum equations again.

I believe that travel beyond the speed of light within our known universe is not possible because that would create a paradox where the particle would supercede the current expansion of the fabric of spacetime and therefore would have nothing (no universe) to travel into. On the other hand, the string theory, supersymetry, and the M and K theories all hint at the possibiltiy of extra dimensions and membranes. My humble understanding of a brane in string theory is the almost 2 dimensional (from a distance) appearing universe that we know and reside in is expanding at the rate of the speed of light since the big bang within the body of a much larger existence and these branes are like parallel sheets or slices of bread in a loaf. each slice or brane may hold entire universes similar or very unlike our own, all existing right here where we aren't even aware of them.

What would happen if matter as we know it (in our universe) were somehow to escape the velocity of the speed of light (say inside the schwarzschield radius of a black hole) then that matter would do something that as yet, is unimaginable.

It is not theoretically possible to accelerate something past speed of light due to the amount of energy required to get something to the speed of light (infinite amount). But hypothetically, if it could...I think the math shows that it would travel backwards in time. A theoretical particle that does this is called a "tachyon". It travels faster then light backwards in time, but does not accelerate there. It is just created there. M-Theory really says nothing about going past the speed of light.

i'm borrowing from the positioning below: "the main important distinction between a regulation and a theory is that a theory is a lot greater complicated and dynamic. A regulation describes a unmarried action, while a theory explains an entire team of appropriate phenomena. " "An analogy could be made employing a slingshot and an motor vehicle. a scientific regulation is nearly a slingshot. A slingshot has yet one shifting section--the rubber band. in case you place a rock in it and draw it back, the rock will fly out at a predictable velocity, based upon the area the band is drawn back. An motor vehicle has many shifting areas, all working in unison to accomplish the chore of transporting somebody from one factor to a different factor. An motor vehicle is a complicated piece of equipment. at times, advancements are made to a minimum of a variety of of element areas. a sparkling set of spark plugs that are composed of a greater proper alloy which could face up to warmth greater proper, as an occasion, ought to replace the present set. however the function of the motor vehicle as an entire keeps to be unchanged. A theory is extremely like the motor vehicle. factors of that's replaced or more advantageous upon, without changing the final fact of the theory as an entire."

Not yet.

The large hadron collider at CERN that comes on stream this year will reach energies capable of testing predictions of M theory. If within 6 months or so it has not found the expected effects then M theory is wrong.

Even then the multiple universe interpretation of the math (which is far from widely accepted) will be untestable - this means that this aspect of M theory is not really a theory in the commonly accepted scientific sense - its more like a religion.
