QUESTION:

If you travel at high speed, then compared with your friends who “stay at home,” you are

(a) older.

(b) younger.

(c) neither younger nor older.

(d) longer.

ANSWER:

Step 1 of 2

If you travel at speeds close to the speed of light, then, compared with your friends who "stay at home" you are younger.

When traveling at a rapid rate away from the observer, one's clock slows down. As a result, we saw that we were younger than our friend who stayed at home when we traveled at a high speed due to time dilation.Time stretches at high speeds so for the person moving at high speeds, time will slow down hence he will appear to be younger than his friends at home.
