Question

Suppose a star that is 100 light-years away explodes today. Will you be able to see the explosion. Why or why not?

Answer 1

Answer:

A light is the distance that light travels in vacuum in one year. If a star is at a distance of 100 light years then it would take light, 100 years to reach earth.

Therefore, after 100 years the explosion will be visible to people on earth.
