Theories on the Origin of the Universe

• Various theories exist to explain the universe's beginnings.
• Steady State Theory proposes a constant density of matter over time.
• Planetesimal Hypothesis suggests planets formed from small solid particles.
• Tidal Theory involves gravitational interactions leading to the formation of celestial bodies.

Life Cycle of a Star

• All stars originate from a nebula, a vast cloud of gas and dust.
• Gravity consolidates material in the nebula, forming a protostar, the initial stage of a star.
• Nuclear fusion ignites when the protostar becomes hot enough, marking the birth of a main sequence star.
• As a main sequence star exhausts hydrogen, it becomes a red giant or red supergiant.

Death of a Low or Medium Mass Star

• A red giant sheds its outer layers, creating a planetary nebula.
• The remaining core cools and becomes a white dwarf.
• Eventually, the white dwarf depletes its fuel and becomes a black dwarf, marking the end of its life.

Death of a High Mass Star

• A red supergiant can end its life in a dramatic supernova explosion.
• Post-explosion, remnants may form a neutron star, composed mainly of neutrons.
• The most massive stars may collapse into black holes, representing the ultimate endstate of high-mass stellar evolution.
