What should your hypothesis be for the life cycle of a star?

Answer 1

A hypothesis for the life cycle of a star could be that a star forms from a dense cloud of gas and dust, undergoing gravitational collapse until nuclear fusion ignites in its core. This process leads to the star entering the main sequence phase, where it fuses hydrogen into helium. Eventually, as the hydrogen depletes, the star expands into a red giant or supergiant, depending on its mass, before shedding its outer layers to form a planetary nebula or collapsing into a supernova, ultimately leaving behind a white dwarf, neutron star, or black hole.
