Question

The distance light travels in one year is called a light year. It is about 5.88 trillion miles and is used to measure stellar distances. At present, it is thought that the edge of the universe is about 14 billion light years from earth. Traveling at the speed of light, how long would it take you to reach the present edge of the universe? O 600 trillion miles O 14 billion miles O 14 billion years O 5.88 trillion light years

Answer 1

Answer:

14 billion years

Explanation:

The distance of the edge of the universe = 14 billion light years

Light year is used to measure the distance which is equal to the distance traveled by the light at the speed of approx $3\times 10^8\ m/s$ in one year.

It means that to reach the edge of the universe which is 14 billion light years apart , if one is travelling at the speed of light which is $3\times 10^8\ m/s$, it will take 14 billion years to reach there.
