Horava Lifschitz theory and Lorentz Invariance

[windy miller]

As I understand it Horava Lifschitz theory breaks lorentz invariance at high energies.
Does this mean we should see photons from gamma ray bursts leave a signal of varying speeds of light for different frequencies?

 

[Demystifier]

Not necessarily.

 

[windy miller]

Not necessarily.

Cn you elaborate? Why not? What does it depend on?

 

[Demystifier]

Horava theory is a theory of gravity with some free parameters. The phenomenological consequences may depend on the exact values of those parameters.

 

[windy miller]

Thanks for that , can you elaborate on the nature of these free parameters,?sorry to be a pain just trying to understand a bit better.

 

[Demystifier]

It's quite technical, so I would suggest to take a look at the Horava's paper.
