hi,
I have trouble to understand something in special relativity.
Heres my question.
How can two light particles approach eachother and not exceeding the light speed ? because both particles are travelling with light speed so they should approach with 2xC but according to relativity they approach each other with 1xC.
How ?????

Why should they?

to an observer the two photons would appear to be traveling at the speed of light. they would pass each other, both going the speed of light. there is nothing wrong with this. no single object is going faster than light.
if you are talking about one of the photons as an observer, well photons are traveling at light speed so they don't experience time, and therefore cannot observe other objects traveling at all!
