Question
In explaining the 'twin paradox' one twin on a spacecraft sees her sister's clock moving more slowly than her own, and the sister on Earth sees the clock of the sister on the spacecraft moving more slowly than her own. In explaining the true results of this 'paradox' it is concluded that...A. When both sisters are rejoined, they will have aged the same amount
B. When both sister are rejoined, the sister on earth will be younger than the sister on the spacecraft because she will age normally
C. When the sisters are brought together the sister from the spacecraft will be younger because the lack of gravity in space prevents aging
D. When the sisters are brought together the sister on Earth will be younger, because living at high speed tends to age people
E. When the sisters are rejoined the sister from the spacecraft will be younger because it was she who experienced a change in velocity.
Explanation / Answer
acc. to time dialtion,
t' = t
when moving with the velocity of light,
time happens to be running slower,
E is correct
