Textbook Question
Chapter 1, Problem 14EAP
Does it Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is cleanly false). Explain clearly: not all of these have definitive answers, so your explanation is more important than your chosen answer.
Example: l walked east from our base camp at the North Pole.
Solution: The statement does not make sense because east has no meaning at the North Pole—all directions are south from the North Pole.
14. The universe is billions of light-years in age.

Describe the purpose of the formula below. Then create a question about the universe
that can be answered using the formula. Calculate the answer and give the accurate
result. Make sure to show
your calculations.

Suppose we look at two distant galaxies: Galaxy 1 is twice as far away as Galaxy 2. In this case,
A.
Galaxy 1 must be twice as big as Galaxy 2.
B.
we are seeing Galaxy 1 as it looked at an earlier time in the history of the universe than Galaxy 2.
C.
we are seeing Galaxy 1 as it looked at a later time in the history of the universe than Galaxy 2.
D.
Galaxy 2 must be twice as old as Galaxy 1.
What is spacetime? Explain in most simplest way with illustration. Like using a garter as an example.

- Part I. We will leam in this class that the distance from the Earth to the Sun is approximately 1AU = 150,000,000 kilometers. a. Convert this number to meters (1 kilometer = 10° meters) and express it using scientific notation: 150000000000 meters How else might you express this number? (Millions, billions, etc. ?) b. A car on the highway drives at 55 mph = 25 meters per second. How long would it take to drive to the Sun? (Assuming you have a car that works in outer space.) Use the equation distance = velocity x time, or time = distance / velocity. Time = distance/velocity = , seconds (don't forget to use scientific notation.)

This is why we don't see light from the edge of the universe in every direction. Friend 2: No, Olber's Paradox describes only light from stars, not from galaxies, and why you can't use light from distant stars to see at night. Friend 3: You're both right and you're both wrong. The paradox concerns itself with the expansion of the universe, and explains why light from the early universe was able to be released. Are any of them right, in part or in whole?arrow_forwardContra Parmenides and a previously universally accepted idea, at the end of his life, Stephen Hawking made the argument that a. the universe can and will create itself from nothing b. the cosmos is an illusion c. the cosmos does not exist d.
