In a day to day situation, if we want to find how much time does it take a person to go from Point A to Point B, we can use the equation T= D/V. In this equation, D represents the distances in meters between Point A and Point B, and V represents the speed (meter/ second) of how fast a person walks. In mathematical terms, it uses the total distance traveled to divided by the time to get an estimation of the average speed(second). But, if we want to find out the age of the universe ? Then, we need to take it into the universe’s perspective. In 1929, Edward hubble discovered that distance of the galaxies is proportional to the speed of our galaxy. Later, this discovery was confirmed with with what scientists saw through the telescope. Thus,
