This is what light can have mass and momentum despite having zero rest mass. -
minecraft-physics 25th Oct 2014Most mathematicians will tell you this: when you multiply zero by infinity, you get a finite result.
-
minecraft-physics 25th Oct 2014Which, you'd think would be a divide-zero error. However, according to most mathematicians, 1/0 isn't just an error- as v--> 0, L--> infinity.
-
minecraft-physics 25th Oct 2014You see, when v=c, Lorentz Factor L=1/sqrt(1-c^2/c^2) =1/sqrt(1-1) =1/0
-
minecraft-physics 25th Oct 2014Light (photons) have been shown to have zero REST mass- meaning that if you weighed a photon using a set of scales travelling at c, you wouldn't measure any mass. However, something very weird happens to the m=(Lorentz factor)m0.
-
minecraft-physics 25th Oct 2014However, in order for momentum to be conserved, mass must also increase with velocity according to the Lorentz factor. m=(m0)/sqrt(1-v^2/c^2)
-
minecraft-physics 25th Oct 2014When a particle has velocity relative to an observer, it was shown through special relativity that time dilates (slows down) according to something called the Lorentz factor, 1/(sqrt(1-v^2/c^2))., where t=(t0)/sqrt(1-v^2/c^2) where t is measured time, t0 is proper time, v is velocity and c is the speed of light.

minecraft-physics 25th Oct 2014sentinal-5, I'm sorry but I must beg to differ. The key problem in this discussion has been that people haven't differentiated between rest mass and mass- these are two different things.

Ferne, by definition, matter is anything that has volume AND mass. So yes, matter does neccasarily have to have mass -

if anyone tries to contradict that, surely you are saying you can prove Einstein wrong. good luck when the entire scientific community comes smashing through your door.
