This is the type of saves I like. Also, w h o o s h .
FINALY!!! a front page save about nuclear science!
before remove: Cherenkov Radiation after remove: Fukushima Radiation (no offence to the japanese with their lovely fish) I like science. WOOSH.
Remove the NSCN 4 teh lulz. By the way, I love science. not that anyone cares but i decided to do something useless today.
No, photons do not have mass, but they do have momentum. The proper, general equation to use is E^2 = m^2c^4 + p^2c^2 So in the case of a photon, m=0 so E = pc or p = E/c
Astro, photons don't really have mass, because when objects collide, the photons push off of eachother. It is the nuclear forces that cause collisions, as well as electron collisions.
well, photons do have mass, otherwise the solar sail wouldn't work
@astro-nomical its in vacuum I had the thought that bcause of the high speed and quantum fluctuations it could be possible that light actually gets some mass by chance and then time dilation kicks in and you have light at infinite speeds ^^
cherenkov radiation is formed in water, and gives a blue glow I thought?
e-man, look at the comments below...
