according to theory of relativity the time stopped for object reaching the speed of light. But it doesn't stop for light, if it does then howcome it takes 8min to reach earth from sun
Answers
Answer:
The simple answer is, "Yes, it is possible to stop time. All you need to do is travel at light speed." The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein's two Relativity Theories.
Answer:
Light travels at the speed c this speed is finite and with out using any relativity we can calculate the time it takes for something travelling at this speed to reach us: time=Distancespeed or t=dc=8 minutes in this case.
For a person travelling very close to the speed of light with velocity v from the sun towards the earth time does slows down, and he goes past the earth in a matter of seconds. But for us time doesn't slow we see the person with almost the speed of light and the time it takes to reach us is again t=dv which will be almost 8 minutes but slightly longer.
Now for light you say time freezes completely this is not really accurate, but for arguments sake I will accept it: Then the same logic applies as before. For light it seems that zero time has passed but for us it is still 8 minutes.
This might seem like a paradox, but time is relative in Einstein's theory of relativiy.
Note that your argumentation is backwards, "time reaches zero for light, because everything is at the same place". While the more "correct" way to say it would be that the photon does not experience time and therefore everything seems to be at the same place.
