I know in special relativity the velocity addition formula isn't just v1+v2=v3 .
But what I fail to understand is why ??
How come that V1+V2 is not V3 if V1 and V2 are traveling at light speed.
ok, but you did understand my question.
I you turn your flash light towards me and I do towards you how fast do the two light beems reach each other ?
1xC or 2xC ? I guess 1xC, but why ?
Theres something I don't understand.
Assume we have two light particles that approach each other. (obviously with light speed)
Logically since each of them are traveling with the speed of light they should approch to each other with 2xC, but according to relativity theory they approach...
