Step 1: Convert 72 km/s into 72,000 m/s to be able to divide by Mpc in the next step.
Step 2: Use the formula V=H0D Get H0 by itself, to use for step 3 To do that divide V by D Getting H0 = V/D
Step 3: Find the megaparsecs unit of distance Mpc = 3.086 x 10^22 m (was given) H0 =72,000 m/s / mpc H0 = 72,000 / 3.086x1^22 m
H0 = 2.33 x 10^-18 s^-1
Step 4: To find the time use the formula given T = 1/H0 1/2.33 x 10^-18 s^-1 s^-1
Step 4: Use the following formula (m/s) / m = 1/s = s^-1 = 4.286111111^17 s
Then divide 4.286111111^17 s by (1min/60sec)(1hr/60min)(1day/24)(1yr/365days) = 1.3591618^10 = 13,591,691,800 billion years Finding the calculations of the Universe was a challenging yet easy thing to do. Challenging, because one has to use many formulas and do many different calculations. Easy, because once one the numbers needed were found, they just had to be plugged into the given formulas. Finding the final answer and knowing it was right, makes one feel as if he or she is a scientist or even a genius and have more interest in the Universe.
Origins are important to scientist because it helps them understand the age of Universe more. An explanation for the universe’s origin, which has been around for decades, is the big bang theory. Stating that around 15 billion years ago a huge blast or bang made the Universe’s matter and energy. Yet, in a study done of scientists across America more than 75% of the scientist said, “ There was no origin of the Universe. The Universe was eternal.” The Origin of the Universe. A bit contradicting don’t you think?
Knowing the age of the Universe helps people define the rate of expansion. From reading, Creation of the Universe I understood that the Universe’s expansion is moving at a fast speed but due to a mysterious property of space called dark energy, it shows
