PHOTONS and SR |
a muon travelling close to the speed of light gets heavier , it gets
contracted and its lifetime increases.
if we imagine a photon at sub light speed :
a photon has no rest mass
as it velocity approaches c its mass is unaffected.
take gamma = sqrt (1 - v^2/c^2)
at v=c , gamma = 0
at c it still has no mass as gamma * zero is still zero
its lenth is contracted until it becomes zero at c as l * gamma = l * 0
= 0
its lifetime becomes infinite as t/gamma = t /0 = infinity
therefore a photon has zero mass, infinite life and takes up no space
whatsoever just like a point in a cartesian co-ordinate system.

that should read
mass = 0 / gamma = 0/0 which is an indeterminate form which can be
zero in some cases .

Nothing changes in its own reference frame. Special Relativity is a
point of view effect defined by the finite propagation speed of
information: lightspeed. Spheres do not contract, they Terrell rotate
unles they are coming right at your nose. Leptons are
zero-dimensional particles. Muons are leptons.
if we imagine a photon at sub light speed :
Idiot, by definition.

Meaningless drivel. Leptons have rest mass and they are still point
particles - including muons. You cannot use an assumption to prove
its derivation. Tommy Aquinas was the expert in doing that, and he
was voluably full of *****.

Imagining that is equivalent to assuming that SR is incorrect.
In SR, all massless particles always move at c.
