Hello, I was wondering if someone more knowledgeable in loop-quantum gravity or string theory could discuss a bit about the following topic for me:
If there is a lower size limit (or length itself is quantized), does this (or can this) mean that there would be a dispersion relation for light in vacuum (for example like the phonon dispersion relation due to the fact that there is a finite lattice spacing)?
If you are knowledgeable in other "beyond the standard model" theories, I would be interested to hear their qualitative predictions as well.
And finally, if any theories do predict a dispersion relation for light in vaccuum, have these been calculated? (if possible, can you please provide references to papers where I could read up on this)
Thank you very much.
