What happens when you switch on a light?
Where do the photons come from?
Did they exist before you switched on the light?
Photons are created when an electron changes its energy state but when you switch off the light and the electron falls back the photon isn't sucked back in.
In effect - the photon is created out of nothing.
I thank you.
