As a consequence of Einstein’s theory of relativity, the rate of time passage is different for a person in a stationary position and a person in motion. (Hard to believe, but true!) To the moving observer, the rate of time passage is slower than that of the stationary observer, that is, the moving person ages slower than the stationary observer. (This fact has been proven many times by experiments with radioactive materials.) The effect is called “time dilation” and is really only noticeable when an object is traveling at near the speed of light (186,000 miles per second). Considering these ideas, try to solve the following problems:
Two people have identical clocks. One is standing on the earth and the other is moving in a spacecraft at
the speed of light, 176,700 miles per second. The moving person’s rate of time passage at this speed is about
times as fast as the person standing on earth.
- If two days of earth time pass, how many days actually pass on the spacecraft?
- If 30 years of earth time pass, how many years have actually passed on the spacecraft?
-
years have passed on the spacecraft.
- If 30 years have passed on the spacecraft, how many years have passed on the earth?
- A space traveler makes a round-trip voyage to the star Capella. The trip takes her 120 years (traveling at 176,000 miles per second). If it is the year 2000 on earth when she leaves, what earth year will it be when she returns?
(a) Step 5: The time passed in space is
days.
(b) Step 5:
years have passed on the spacecraft.
(c) Step 5:
years have passed on the earth.
(d) Step 5: Earth year when she returns will be 2387.
