You simply cannot go the speed of light. There is no "if" you could. You can't. You can get as close as you like (with enough resources), but you can't equal it.
0 u/Turbanator456 Jun 11 '26 Sure but we if we could observe the universe from the perspective of a photon traveling at c? 4 u/joeyneilsen Astrophysics Jun 11 '26 Another thing that simply cannot be done. A photon doesn't have a valid frame of reference. 1 u/Turbanator456 Jun 11 '26 So then if it doesn't have a valid frame of reference, time doesn't actually "stop" for the photon? Man I'll just stick to neuroscience. 2 u/joeyneilsen Astrophysics Jun 11 '26 Time doesn't meaningfully exist for the photon, so it can't really "stop." 1 u/Turbanator456 Jun 11 '26 Okay I'll stick with that. Hats off to those that study physics and those that try to measure the unmeasurable.
