Hey I'm getting muddled deciding which forces are responsible in individual particle decays. I'm looking at the hyperphysics page: http://hyperphysics.phy-astr.gsu.edu/hbase/forces/funfor.html Here it says that the photon mediates the EM force. So does that mean that if photons are...

Thanks guys, I think I'm clearer now... So; any fundamental observer in their own frame of reference sees their clock running at the cosmological time. But then if they were to observe another observers clock which was moving relative to theirs, they would observe tau, the proper time. So...

Hey If you have the Minkowski line equation of -ds^2 = c^2 d tau^2 = c^2 dt^2 - dx^2 - dy^2 - dz^2 I don't understand how you can assume from this ^ that each observer in different reference frames will experience time changing at the same rate 'dt'. I thought that tau was the relative...
