I was just wondering if light can pressure onto of light, perhaps in a blackhole and what would be the effects of light pressuring together on itself ?

What do our equations say will happen to light if it pressures on top of itself, is this theoretically possibly by our current theories/understanding ?

Perhaps light falls into the blackhole so fast that it never pressurises on top of itself or maybe it does, I don't know ! ;)

(Could be interesting to dump some light equations into this thread so maybe it can be computed on a computer =D)

Bye,
Skybuck.

Our current best model of light is the standard model. In it, light
(photons) does not directly interact with other light, in any way. It is
possible for there to be indirect interactions, but they are very, very
small and have not been observed.

So light generating pressure on other light does not happen to any
significant extent. This is so both inside and outside any black hole,
except of course right at a singularity we don't know what happens.

I thought the indirect interaction (photon-->virtual e+e-, photon2+e-->something
interesting) were observed in intense radiation fields and was responsible
for certain interactions observed in particle accelerators? I am wrong?
