I answer is not 100, I also tried 21. I need help! Thank you!
Consider three periods in the history of the Universe: one million years after the Big Bang (age = 1 million years), about five billion
years ago (age = 9 billion years), and today. What is the ranking in the expansion rate of the Universe in these three period, from
fastest to slowest expansion:
O 1 million years, today, 9 billion years.
today, 1 million years, 9 billion years.
today, 9 billion years, 1 million years.
O 1 million years, 9 billion years, today.

- What major factor determines the future of the universe? Why?arrow_forwardThe Sun is moving at 220 ??/? around the Galactic Center at a more-or-less constant distance of 8.5 ???. To appreciate how remarkable this is, consider the following questions: a) How massive would the Sun have to be for the Earth to have an orbital velocity of 220 km/s at 1 AU? b) How fast would the Earth move if it was in orbit around the Sun at a distance of 8.5 kpc? Of course, you may ignore the effects of all other stars in this calculation.arrow_forwardWhat are a couple of scientific speculations that describe the future of our universe?arrow_forward
- What is the Big Bang? What evidence do we see in the Universe that everything-which-exists exploded oddly out of nothing and for no rhyme or reason?arrow_forwardYour friends are talking about Olber's Paradox: Friend 1: When the universe was quite young, it was also quite small, and therefore light was trapped inside the universe. 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_forwardIf you will compare the balloon to our universe, with the dots / markings as galaxies or galaxy clusters, what can you say about the distances of the galaxies as continuously expands?arrow_forward
- Where is Uranium produced? Group of answer choices In the early universe after the Big Bang. In the cores of massive stars. In the outflowing material from supernova explosions. In molecular clouds.arrow_forwardIs the universe open or closed?arrow_forwardThe Milky Way grew through merging with many smaller galaxies. What are the observational signatures of this process? O The motion of old stars in the bulge and halo of our galaxy are randomly orientated, meaning they were formed from collisions of small, accreted, galaxies all on different paths. O The ordered motion of the bulge / halo stars means that they came from many objects. The random motions of stars in the disk means it was formed from collisions of small, accreted, galaxies. O The motion of young stars in the disk are all in the same direction, meaning they came in as seperate objects.arrow_forward
