Thus, to be able to travel 13.7 billion light years in one day, a person would have to go at approximately the square root of (1- 10^-26)multiplied by the speed of light. The figure that you arrive at is the distance from Earth to the edge of Earths visible universe, which is the portion of the universe that an observer on Earth could possibly observe. The Cosmic Perspective – A textbook on Astronomy.Īpply the time dilation formula of special relativity that you shall find in the book The Cosmic Perspective and calculate how fast a person would have to go in order to travel 13.7 billion light years which in their relative time they would perceive as one day.That distance which is about 13.7 billion light-years away.
The objective of this investigation is to scientifically be able to calculate the constant velocity, one at which a human being who is in a spaceship would need to travel in order to go from the earth to that portion of the universe that is visible from Earth.
