The correct answer is C. The distance to the edge of the universe
Step-by-step explanation:
The universe comprises everything that exists: our planet, solar system, the milky way (galaxy where our solar system is located) and thousands of galaxies, planets, stars, etc. that are far away from Earth. Due to this, the distance of the universe is not known because humans have only observed part of it; this observable universe is around 93 billions-of-years, but it is believed the total distance of the universe is more than the distance estimated. This means the longest distance from Earth is the distance to the edge of the universe as this edge has not been found yet and even the visible universe distance is longest than any other known distance.
