Slower than the speed of light
WebbThe momentum of a particle which is traveling at a speed v less than c is given by p = m 0 *v*sqrt(1/(1-(v/c)**2)) This equation works for particles traveling at speeds less than c. For v=c, it involves dividing zero by zero. Suppose that a massless particle is traveling at a speed v less than c.

WebbI'm really science dumb, so I don't understand how or why this is true. But assuming it is true, then if a super speedster moved their head at the speed of light (or vibrated, I guess, since they couldn't really move their head apart from the rest of their body), would their brain and head age slower than the rest of their body?

WebbThe slowing down of light that we observe in free space should also not be confused with slow, or indeed fast, light associated with propagation in highly nonlinear or struc-tured materials (3, 4). Even in the absence of a medium, the modification of the speed of light has previously been known. For example, within a hollow waveguide, the Webb21 jan. 2024 · The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.
