The mathematical predictions made by scientists tell a story of the life and death of stars.
• How the Hertzsprung-Russel diagram describes the life cycle of stars.
• Depending on its mass, how a star ends its life as a white dwarf star, a neutron star, or a black hole, and where super novas fit in.
• How the mathematical predictions of white dwarf stars, super novas, and neutron stars are slowly verified by the advancement of the astronomical equipment used by astronomers.
Spacetime tells matter how to move, and matter tells spacetime how to curve.
• Why gravity can be seen as a curvature of spacetime.
• That Einstein’s field equations describe how matter curves spacetime.
• How Sir Arthur Eddington verified Einstein’s theory of general relativity by measuring the change in position of stars during a solar eclipse.
We shift our ideas from Newton’s law of gravity to a new set of equations that describe how gravity is a consequence of the curvature of spacetime. Learning Outcomes: • John Michell and his hypothetical object called a dark star. • How to determine the mass of a planet required for the escape velocity of an object to be the speed of light.
• Einstein’s Equivalence Principle.
