I just had a quick question; I’m an armature so please excuse my ignorance. But can photons be attracted to one another? And if so how? Thanks for all your help :)

I am afraid the question is more complicated. After reading a comment in this thread, I searched about this subject and found this: http://arxiv.org/gr-qc/9811052 . There it is shown that two parallel light beams do neither attact nor repel, since their gravitoelectric field cancels their gravitomagnetic field. (If you want to avoid the whole calculations go directly to chapter 4). In case of antiparallel light beams there is indeed an attraction.Tom Mattson said:I've never worked this out, so forgive me if it sounds dumb, but can't photons attract in GR?

hellfire said:I wonder how to figure out the bending of spacetime produced by a photon.
No i am not.dextercioby said:Marlon,are u trying to "assemble" classical GR with quantum electrodynamics...?
If u succeed,then the Nobel for 2005 may be yours...

Yes, photons can be attracted to one another. This phenomenon is known as photon-photon interaction or photon-photon scattering.
Photons interact with each other through the electromagnetic force. This force is responsible for all interactions between electrically charged particles, including photons.
No, photon-photon interaction is not a common occurrence in everyday life. It typically occurs in extreme environments, such as high-energy particle accelerators or the early universe.
Yes, when two photons interact with each other, they can produce new particles such as electron-positron pairs. This process is known as pair production.
Yes, scientists have been able to observe photon-photon interaction in laboratory experiments. However, it requires high-energy photons and specialized equipment to create the conditions necessary for this interaction to occur.
