Study Notes

### Fusion

Fusion occurs at extremely high temperatures, approximately 15 million °C.
At these temperatures, electrons have enough energy to break free from protons, resulting in plasma, a state of matter composed of ions and free electrons.
Despite the repulsive forces between protons, gravity brings them close enough to fuse.
During fusion, one proton transforms into a neutron, releasing a positron (a positively charged antiparticle of an electron) and a neutrino.
Positrons annihilate upon contact with electrons, releasing high-energy gamma rays.
The fusion process results in the formation of deuterium, an isotope of hydrogen with one proton and one neutron.
Deuterium can undergo further fusion reactions.
The overall outcome of these reactions is the conversion of hydrogen into helium, neutrinos, and energy.
