string theory and time dialation

[36grit]

Perhaps time dialation is the key to proving string theory, or Mtheory. Maybe faster than speed of light velocity causes these strings to expand. Heat expands atoms. Maybe these strings have a rest state that is excited by movement, after all these strings are supposed to be gravity, and isn't gravity all about weight and momentum?

String theory is invariant under the (9+1) Lorentz group, if that is what you are hinting at? There are then various other nice symmetries on their world sheets.

 

It is true that string theory contains the gravition as one of its states. This is a wonderful property. You start of with a theory that initially has no obvious contact with gravity and then you are forced to consider a theory that contains gravitons.

I guess this is beyond me. Are you saying that time dialation is pretty much irrelavant to string theory?

As the theory uses Lorentz groups, then there will be such a thing as time dilation in string theory. Time dilation is an "artefact" of splitting space-time into space and time. The true important invariant is the space-time interval.

 

Apart from "relativistic billiards" and some effects in collider experiments time dilation does not feature heavily in the formulation of relativistic theories. One is interested in things that are invariant under Lorentz transformations as these are the things that have true deep meaning in physics.
