Question

a star is 100 light years away from the earth if it explodes today after how much time this explosion will be visible to the people on the earth

Answer 1

If a star, 100 light years away explodes today, the explosion will be visible to the people on earth after 100 years.

 We see what happens to the celestial objects or the heavenly bodies in relation to the light years. For example, we see the Sun 8 minutes after it has risen.

The closest star Proxima Centauri is seen by us as it was 4 years ago since it is 4 light years away from us.

 Thus, an explosion taking place in a star that is 100 light years away signifies that it shall be seen by us after 100 years.
