Are clocks ticking slower for the people on Earth or for the astronauts on the spaceship?

Answer 1

Explanation & Answer

• Humans measure everything relative to the earth & accordingly the limit of speed is the speed of light.
• As something approaches the speed of light, things happen to seem different than observed in day-to-day life.
• According to the great discovery about the concept of time dilation, time seems to run slower for those who are at speeds near the speed of light.
• As mentioned above, this is according to the earth: earth dwellers.
• As seen from the earth, clocks tick slower for the astronauts (answer).

• Things to know in extra, Since everything is relative, the astronauts see that their clock runs faster than those on earth. But that is a sensation only, as they see they are stationary while the earth appears to be moving.
