Article says:
- Similarly, the amount of time it takes a photon to travel one Planck length is Planck time: 10-43 seconds. This is the smallest meaningful division of time.
Shouldn't that be more accurately the amount of time it takes for a particle travelling at the speed of light in a vaccum one Planck length? Photon's can travel slower than the speed of light in a vaccum in some circumstances, can't they? --
