What is the big bang?
Most plausible explanation for the creation of the universe
Nucleosynthesis
The creation of new atomic nuclei, the centers of atoms that are made up of neutrons and protons
Big bang nucleosynthesis
produces H and He (primordial nucleosynthesis)
Stellar Nucleosynthesis
Would not be possible without the formation of stars
Supernova nucleosynthesis
Co and other elements
H + He Fusion
Product is Li
Main sequence star
H -> He (proton and proton)
Red giant star
Triple alpha process (He -> C)
Supernova
Explosion of red giant star
Black hole
Area where gravity is extremely strong (Li to Fe)
