I am wondering how it is possible that we see CBR. Here's why:
When the big bang occured, there was a sea of particles that gave off radiation. Now, if we are now made out of those particles, then how are we seeing their radiation now?
The only way I see this happening is if matter travelled faster than light at some point. How else would we be seeing the radiation from the same particles we are made out of? It would be violating the light-cone rules. Can someone clarify this for me? Thanks
