Where is the light generated?
The sun. How did the sun form and why does it produce light? Gravity pulled some hydrogen into a ball, enough of it was there that gravity forced it to fuse.
- boomboomsubban 4y agoSure. Our energy is still derived from the photons released by the sun, even if the sun needed gravity to form. Gravity is necessary, but isn't the source of the energy.
- washbrain 4y agoI mean, I guess. The fusion that causes photons doesn't happen without gravity though.
- boomboomsubban 4y agoAnd fusion happens through an interaction of the weak nuclear force. Finally, without the strong nuclear force there wouldn't even be hydrogen atoms for any of this to happen. All four are necessary, the energy we use comes from electromagnetism.
