- In the reading, you were told that there were roughly 10,000 galaxies in the image of the Hubble Ultra Deep Field alone. The image is roughly 10 square arcminutes and there are roughly 1.5*10^8 square arcminutes composing the entire sky. With that in mind and assuming that the Hubble Ultra Deep Field represents an average part of the sky, roughly how many galaxies may exist in the observable universe? (Please include commas for every factor of 1,000; for example 2,343,567,890)How many times longer than the length of recorded history is the age of the universe? I was also given that the length of recorded history is 10E11 s, and that the age of the universe is 10E18 s. But, when putting 10E18/10E11 = 10E7, I get the wrong answer.Calculate the age of the universe for the following Hubble's constant, (a) 30 km/s/Mpc
