Question:
If a twin having age 20 years and one of them went to the space-craft and other
one stayed at earth surface. After ten years what will happen to them with their
age? Explain.
Thanks

Answer 1

There exist age difference between a twin where one stay on earth while the other spends on space. after ten years the one who was in space will be younger than the one who stayed in the earth surface. the twin in low orbit on space age slightly slower than the twin on the earth surface since the velocity component of time dilation is greater than the effect of reduced gravity.
