How is a photon emission energy balance maintained ?
If an electron is in motion across space at 260,000 kilometers per second, and it releases a photon in that same direction of travel, the photon will be in motion across space at the speed of 300,000 kilometers per second, thus there will be a difference of 40,000 kilometers per second.
If another electron that is traveling along side the first electron at 260,000 kilometers per second, and it releases a photon in the reverse direction, the photon will be in motion across space at the speed of 300,000 kilometers per second, thus there will be a difference of 560,000 kilometers per second.
In both cases each electron will lose energy when releasing a photon. Is the loss of energy equal in both of these cases ? ( assuming each photon is is identical in its properties of course )
