A: yes. Precisely. Which means ----- are you seated?
Photons have no ticking time at all, which means, as far as they are concerned, they are absorbed the instant they are emitted, even if the distance traveled is across the universe itself.
- fragsworth 15y agoAnd we, as humans, are emitting photons right now. Little pieces of us are right now instantly traveling across the universe and colliding with other stars, planets, etc., or flying through the void - instantly - to who knows where?
- Jach 15y agoThis answer bothered me. Is he just saying that any supposed delays of "light" we can set up through experiment are really just delays in instantaneous absorption/emission pairs, or is he talking about entangled photons, or some preferred space of simultaneity, or photons not being particles but vectors in a timeless configuration space?
- galadriel 15y agoMost probably he is talking about the fact that proper time for all events in Photon's own frame is zero, i.e. a frame that move with speed of light will notice that all events are instantaneous.
- teamonkey 15y agoI loved this reply. Clarifying and correct, as far as I can tell. http://www.reddit.com/r/IAmA/comments/mateq/i_am_neil_degrasse_tyson_ama/c2zga4o http://www.reddit.com/r/IAmA/comments/mateq/i_am_neil_degras...

- retube 15y ago> Photons have no ticking time at all, which means, as far as they are concerned, they are absorbed the instant they are emitted, even if the distance traveled is across the universe itself Yes. Or another way of looking at it, from a photon's perspective the Universe has no size at all! I love that.
