Life оf а phоtоn - I wаs creаted in the of the Sun where hydrogen nuclei fused into one . The difference of mass between the final product of the nuclear fusion and its initial components is transformed into energy according to Einstein's famous formula . Since the speed of light is a very large number, Einstein's formula implies that a small amount of mass can be transformed into a large amount of , which is converted into high-frequency and neutrinos. After bouncing around for 100,000-1000,000 years in the radiative zone, I lost energy and reached the photosphere as a visible photon. I then traveled for about 8 minutes before reaching my final destination, .
