Thanks for your answer, and what are these other processes? I'd be curious to look them up.

I just saw a documentary about the detection of neutrinos, and the first detection using chlorine atoms was able to detect only electron neutrinos which accounted for about 1/3 of the total number of neutrinos predicted. The muon and tau neutrinos weren't able to be detected by that method. My...

Why don't ice cubes spontaneously form in a cup of water? Someone was explaining to me that for ice cubes to spontaneously form, the water molecules would have to go to a more ordered state. I know about the spontaneous symmetry breaking that occurs when water is at 0'C, but I was wondering if...

Yes, each galaxy exerts gravitational force on every other galaxy in the local group, just like the supermassive black hole in the center of our own galaxy that causes the stars to orbit around it. Also, a cluster of galaxies can be gravitationally attracted to other galaxy clusters, which...

Thanks for answering my questions, everyone. :)

I have read somewhere that you need to have zero mass to be able to travel at the speed of light; is this true? Also, light is a wave, waves contain energy, and energy and mass are interchangeable according to E=mc^2, so wouldn't light have mass and thus contradict the first statement? Thank...
