- Was the Big Bang an explosion? Explain your answer.what is the scientific concept used in the test? how old is the rock in years? scientist agree that the age of the universe is about 4 billion years old, does the age of the rock referred in the problem support that? why?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)
