David wanted to test the theory of Einstein. To that end, he measured the time perceived by an airline pilot, who naturally traveled very fast. He labeled it as case A. To compare the pilot with a slower traveler he measured the time perceived by a semi truck driver covering the same distance. He labeled it as case B. He was amazed by the counter intuitive results he got from the experiment. According to Einstein, would case B seem to gain less or more time than case A?
Ans: less
