- 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?Does it make sense to ask, “If the universe is expanding, what is it expanding into?”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.Need help, need to know if I'm doing this rightWhich of the following can be concluded from the two premises below: 1. Whatever begins to exist has a cause 2. The universe began to exist some 14 billion years ago a. the universe must have a cause b. nothing c. the universe caused itself d. there must be a multiverse
