Speed ya light ni 3 x 10^8/s kwa observer anayeiangalia ray of ligh, kama wewe na mimi.
Kutoka kwa perspective ya ray of light, per relativistic calculations, if a ray of light had consciousness, moving at that speed (speed of electromagnetic waves in a vacuum), the universe would appear timeless.
From the perspective of a ray of light, time stands still.
If you are familiar with relativity, per relativity, the more you approach the speed of light, the more you slow down the passage of time (time dilation).In a purely theoretical thought experiment, if you were able to reach the speed of light, time would stand still.
From there, moving faster than the speed of light is similar to moving backwards in time.
For a photon moving at the speed of light, it is equally valid to say that time does not exist or distance does not exist, it is everywhere along it's path at once.
Hapa wameelezea kwa mfano mzuri wa kutafuta muda unaochukuliwa na photon kutoka kwenye jua mpaka duniani, kutoka kwenye perspective ya photon.
Einstein's relativity tells us how motion through space affects how our clocks run. But it all breaks down when you move at the speed of light!
