Can virtual photons travel faster than light?
In quantum mechanics, virtual particles may travel faster than light, and this phenomenon is related to the fact that static field effects (which are mediated by virtual particles in quantum terms) may travel faster than light (see section on static fields above).
What speed are photons emitted at?
Photons are massless, so they always move at the speed of light in vacuum, 299792458 m/s (or about 186,282 mi/s)….Photon.

Do photons travel faster than the speed of light?
Science: Can photons travel ‘faster than light’? LIGHT cannot travel faster than it does in a vacuum. This, at any rate, is what Einstein postulated in 1905. The proposed effect, however, is very small indeed: the photons can exceed Einstein’s limit by only one part in 1036.
What if the speed of light was faster?
If the speed of light was, say, 100 km/h, we could experience the effects of special relativity in our day to day lives. Cars passing by would appear as pictures on a sheet of paper. Their headlights would be dark blue, perhaps even brightly violet, while their tail red lamps would be invisible.
Why photons travel at the speed of light?
Some people say that the reason a photon travels at light speed the moment it is created is because it is a massless particle, and therefore must always travel at the speed of light. All quantum objects are partly waves and therefore can have a speed the moment they are created.
Why do photons always travel at the speed of light?
How do electrons emit photons?
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
What travels faster than photons?
An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light.
