Main Question or Discussion Point
How much mass does the sun add to the earth each day?
It would contribute thermal energy, though. While the mass of any individual particle doesn't increase, the mass of the system does, doesn't it?2) e = mc^2 doesn't just happen.
Solar wind or not, our atmosphere does "evaporate," which is why it doesn't have much in the way of lighter elements - like hydrogen.Originally posted by FZ+
I thought the solar wind was removing matter from Earth's atmosphere...

2) You have to have a specific event, such as a photon producing an electron and a positron. But in order to do that, the photon has to have enough energy to cover the masses of the two particles, 1022 electron volts. And the only photons with that kind of energy are up in the gamma ray range. Very few solar gamma rays (there are a few), make it down to the surface of the earth.
