If I could exceed the speed of light in a vacuum, would I be able to see photons that I previously emitted?

Would this be theoretically possible?

    $\begingroup$ How can you cross a speed? Do you mean crossing a light beam? $\endgroup$ – Exocytosis May 12 '19 at 5:59
  • $\begingroup$ yes, maybe the beam also.. the velocity/speed of light is 300,000 km/s. if I cross this number, such as 300,000+ km/s.. what would happen? would I see the quantum of light? $\endgroup$ – Shadman Shourov May 12 '19 at 6:06

    $\begingroup$ Well first from a theoretical perspective you cannot reach this speed at all, as this would require an infinite energy. There is an interesting video that show light propagation in slow motion: youtube.com/watch?v=snSIRJ2brEk $\endgroup$ – Exocytosis May 12 '19 at 6:12

    $\begingroup$ I reread your sentence, you added a plus to the speed. If your hypothesis means to go faster than the speed of light in vacuum, your hypothesis is just unrealistic and you cannot ask it here. $\endgroup$ – Exocytosis May 12 '19 at 6:46

    $\begingroup$ @Nat: the OP seemed to talk about the speed of light in the vacuum, not just the speed of light, which can be slowed down in a medium. I'm saying that because of your edit. The title is not complete, nor the rest. $\endgroup$ – Exocytosis May 12 '19 at 7:44

Apparently your comments show that you mean going faster than the speed of light in a vacuum, so the answer to your question is no, this is not theoretically possible.

  • $\begingroup$ then i wouldn't see the quantum of light ? right? $\endgroup$ – Shadman Shourov May 12 '19 at 7:08

    $\begingroup$ No but only because you cannot do this experiment at all in the first place, not even in theory. $\endgroup$ – Exocytosis May 12 '19 at 7:10
