The red shift The Red Shift is a phenomena where light coming off of distant galaxies appears to be 'redder' in color than they should be. Astronomers usethis data as evidence that the universe is expandingUse what you know about the Doppler Effect to explain why this red shift phenomena provides evidence that the universe is expanding

Concept explainers

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.

If you use an Earth-based telescope to project a laser beam onto the Moon, you can move the spot across the Moon's surface at a velocity greater than the speed of light. Does this Violate modern relativity? (Note that light is being sent from the Earth to the Moon, not across the surface of the Moon.)

Figure P38.21 shows a jet of material (at the upper right) being ejected by galaxy M87 (at the lower left). Such jets are believed to be evidence of supermassive black holes at the center of a galaxy. Suppose two jets of material from the center of a galaxy are ejected in opposite directions. Both jets move at 0.750c relative to the galaxy center. Determine the speed of one jet relative to the other. Figure P 38.21
