Does light have a frequency limit?

[NateTG]

So basically there is no limit, thanks.

In GR and SR, there are no limits. In Quantum theories, there are limits imposed by the HUP.

No there isn't, which is the point I've been trying to put across, you can speculate that there may be a limit imposed by yet unknown Planck scale physics, but there's nothingin the HUP that limits the frequency of light.

The HUP is a sliding scale; you can get as accurate as you like in measuring one observable, so long as you're willing to give up accuracy on a complementary observable.

The paper does answer some of my questions..
It's true memoe above a certain energy and the photon will instaneously change into other particles on the slighest interation with any other matter, these partciles if produced by a stupendously high energy photon would be short-lived decaying into a multitude of other particles.

Well,the paper will not tell you the answer to the original question,but gives some consideration relating treatment in transition from weak fields to the high fields.
It wasn't my purpose to point that electron-positron collision at high energy will likely fail to produce cosmic rays.The mechanism of producing them beyond certain range is unknown.Highest cosmic ray energy observed up to date is about 10^20 eV.IMHO,The mechanism apart from relativistic shock must be different.
GR in it's basic form hasn't got the problems giving rise to arbitrary large or low gravitational shifts to the EM radiation trails.On other hand,cosmology
which is intimately conected with GR says there is finite gravitational energy of the universe.
There are heavy problems like vacuum energy,cosmological constant and others that bring out the problematic question of what would observer "measure" in ultra high fields.

cheers

Sorry to gravedig, but I had to clear things up a bit, especially considering this is the first result on google for the maximum frequency of light.
The hints at no upper limit far exceed a limit.
An accelerating expansion of our universe
The problem of dark matter
Nasty infinity, the infinite energy density of vacuum, which is extremely foolishly hidden
The physics community, to put it bluntly, is scared to hell of infinities, but the realization is dawning and infinity is beginning to be studied.
There are places in our universe where the rules don't apply like they usually do.
Infinitely high energy photons could exist for infinitely small timescales.
Only time will tell.
