AST 101 Lecture Notes - Lecture 25: Solar Mass, Lorentz Factor, Main Sequence
Document Summary
To an observer outside the train, the ball appears to move faster. Now lets consider jackie moving by at close to the speed of light. She bounces light instead of a ball. The outside observer can not see the light moving faster than c. As jackie moves past you at high velocity . She tries to measure the diameter of your ship. But time moves more slowly for here. So she measures a shorter length than you do (distance= velocity*time) Objects appear shorter to you in the direction which they are moving. As jackie moves by at high speed. You give both her & her identical sisters a push. Time runs more slowly for jackie, so she feels the push for a shorter time. Jackie accelerates less than her sister does. 4 hydrogen into one helium, get one out. Pushing pressure out while bringing other pressure in. 10 m (circle with a dot in it) msun.
