Question

a) She will be younger.

b) She will be older.

c) She will be the same age.

d) It depends on the direction of her journey.

Answer 1

The astronaut who goes on a space voyage at near the speed of light will age slower compared to her twin who stayed on Earth due to time dilation.

Step-by-step explanation:

The astronaut who goes on a long space voyage near the speed of light will age slower compared to her twin who stayed on Earth. This is due to the phenomenon of time dilation, which occurs when an object or person is moving at high velocities. Time dilation causes time to slow down for the moving object, resulting in the astronaut aging less than her twin.
