surreptitious57 Posted February 9, 2016 Posted February 9, 2016 Can photons travel infinitely in a vacuum? What happens to time inside a black hole? What happens to photons inside a black hole? How can it be that energy has always existed?
pavelcherepan Posted February 9, 2016 Posted February 9, 2016 - Yes - ? - They travel to singularity like all else. What happens after we don't know. - The very existence of any object/particle implies it must possess energy. No energy = no Universe.
Strange Posted February 9, 2016 Posted February 9, 2016 (edited) What happens to time inside a black hole? At the event horizon, space becomes sufficiently curved that the time dimension changes places with the radial spatial dimension. So the singularity is no longer ahead of you but in your future. There is no escape! However, I don't think that asking questions like this, with no larger context, is a very good way to learn. If you are asking these questions, it probably means there are some deeper gaps in your knowledge that need to be filled. [edit for spelling] Edited February 9, 2016 by Strange 2
