There is a question regarding the increasing speed that the Universe is expanding. It is stated that it is against the gravity theory. how would you address that paradox?

Light has been defined as a photon, an energy particle, and it is said to be solid. Beyond that???????????

How much mass does a photon have, though?

I donot know. I am not sure whether an estimation has been made. How much mass does solar wind have is in the same catagory.

Actually, photons have no mass, or zero resting mass. They do however have momentum and a realativistic mass can be implied.

An equation often used is; E2 = m2c4 + p2c2 for a photon, m=0 so E = pc or p = E/c.

Exactly! How weird is that?

quantum wierd. God I love QM

*L* You know that we're all probably just a dream in some Schrödinger catnap, right?

What is the c in the equation back atcha?
