Answer correctly and read the questions corretly, this is all one quesiton if done correclty and organized I will write a very nice review about you!
1. How did Edwin Hubble measure the distance to the Andromeda Galaxy?
He deduced it from its redshift.
He measured its parallax.
He used Cepheid variables in the Andromeda Galaxy.
He used white dwarf supernovae in the Andromeda Galaxy.
a. Describe three of the six possible scenarios for the fate of the universe. For each case, describe:
• what conditions will be like
• the curvature of the universe
• which term (gravity, expansion, or dark energy) in the Friedman equation would dominate.
b. Observationally, what scenario best describes our universe? Explain.

- Detailed explanation of each step so I could study for a test C6M.7 Astronomers currently believe that every galaxy has a supermassive black hole at its center and that a typical galaxy has collided with other galaxies several times since the beginning of the universe. Imagine that the central black holes of two colliding galaxies end up, after the collision, orbiting each other in the middle of a cloud of dust and stars. Assume that the black holes have the same mass M (which maybe millions or even billions of times that of the sun) and each is initially in a circular orbit of radius R around the pair’s center of mass (which is halfway between them), and the surrounding cloud has no net angular momentum, as shown in figure C6.14. Over time, frictional interactions with the cloud cause the black holes to slowly spiral in toward each other. If their orbits remain approximately circular as they slowly spiral in, then thespeed of each in its circular orbit will be │V│ = 1/2 (GM/r)^1/2,…arrow_forwardWhat I Need to Know Al the end of this moduke, you should be able to 1. design a research useful in daily Me 2 write research title 3. describe background of research 4. state rosoarch questions 5. indicate scope and delimitation of study 6. present written statement of the problem What I Know Directions: Read and analyze the statements below.
