the brightest star in the universe, a supernova, is thought to be about a million times brighter than our own sun. if polaris, located about 434 light - years from earth, were to go supernova today, why would no one currently on earth ever know it happened?\na it would take the light 434 years to reach the earth.\nb the light would be so dim that our eyes would not detect it.\nc the light would be so bright that our eyes could not detect it.\nd the light from the supernova would never reach the earth as it would travel in a different direction.

Answer

Brief Explanations:

The distance of Polaris from Earth is 434 light - years. A light - year is the distance light travels in one year. So, if Polaris goes supernova today, the light from that event would take 434 years to reach Earth. Currently, no one on Earth would know it happened because the light has not arrived yet.

Answer:

A. It would take the light 434 years to reach the Earth.
