THE MECHANICAL UNIVERSE Name: Mai Nguyen Video 25. Kepler to Einstein Class: PHYS 2426 1. Galileo believed that his explanation of what phenomenon proved Kepler was right? Theory of the tides. 2. Who wrote “Through the Looking Glass?” Lewis Carroll 3. How many tides should we have each day according to Galileo’s theory? One high tide at noon. 4. How does the sun’s effect on the tides compare to that of the moon? Since the sun’s gravity tears at the earth, the suns effect is about half of the moons because it is farther away. 5. What does Kepler’s third law relate? The square of any planets period is proportional to the cube of it’s semi major axis. 6. Explain Einstein’s Principle of Equivalence:

Unformatted text preview: Equivalent of gravitational mass is always equal to inertial mass; equivalence of constant gravity and constant acceleration. 7. According to Einstein, what affect should gravity have on a beam of light? It would bend it slightly because light doesnt travel in straight lines because of the gravitational force of the earth. 8. What astronomical observation made Einstein famous? First great proof of relativity. 9. What is a geodesic? The shortest path between two points. 10. What object is a point of infinite curvature? Black hole 11. What is meant by the Big Crunch? The universe will become smaller and smaller, opposite of the big bang....
