LECTURE 20
questions after lecture
these were challenging, so try them again
now think about these
- Compare how the swimmers' gamma factor came about with how the relativistic gamma factor came about. What is absolute and what changes in the two cases?
- Does the length of a moving object really contract along the line of relative motion?
- Does the time which passes on a moving object really go slower?
- In what sense is time like space? How do we depict the two as similar? How do they differ?
- What is a negative metric?
