Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Check Your Understanding The light of a galaxy that moves away from us is “redshifted.” What occurs to the light of a galaxy that moves toward us?
Suppose you measure the red shifts of all the images produced by gravitational lensing, such as in Figure 34.12. You find that the central image has a red shill less than the outer images, and those all have the same red shift. Discuss how this not only shows that the images are of the same object, but also implies than the red shift is not affected by taking different paths through space. Does it imply that cosmological red shifts are not caused by traveling through space (light getting tired, perhaps)?
Large quanti?es of antimatter isolated from normal matter should behave exactly like normal matter.
