Yes I've tried that. What if an observer watches the two photons travel at each other. Will that observer see the two photons traveling towards each other at 2c?
Hello. I have little knowledge on relativity but I have read the fundamental concepts. What has been confusing me was the following problem:
If a photon A is traveling towards another photon B which is traveling directly into photon A (a head on collision). What will be the speed of photon B...
