The differential cross-section of a collision process in center-of-mass frame of reference is given by
ds/dW=Ar^2sinq.
What is the total cross-section in the laboratory frame of reference?

I was watching manswers last night and they were talking about how the bomb squad dis-arms bombs.
It got me thinking about Einstein idea of how when you're traveling on a beam of light holding a clock in front of you the clock would be still because time doesn't exsist relative to the speed that light travels I at(I think).
So what would happen if you were holding a ticking time bomb while traveling in a straight line on a beam of light? In theory of course
my teacher is giving me extra credit if I can get at answer for this


Would it ever explode sense the detonation of the bomb is purely dependent on time?

How did increasingly sophisticated technology lead to better understanding of the behavior of electrons associated with atoms?

Can you pause energy like light and electromagnetism and if so would other similar energy slam into it or pass threw it and what would be the effects of both?

Astonishing claims that need to be reviwed by experts:

I'd love to hear expert opinions on the info on the link above.

General consensus is that Nuclear FUSION is safer than Nuclear FISSION. We know Fission process is by spliting atoms. Present Nuclear Bombs work on FISSIONprocess. My question is: Is FUSION (safer process) is incapable of producing Nuclear Bombs? If FUSION process is incapable of creating Nuclear Bombs, we can eliminate the threat of Nuclear war by abandoning FISSION technology and adapting FUSION technology (if successful).
