Background (CMB) undertaken by the COBE satellite. Use this diagram to estimate the
current temperature of the CMB. Based on your estimate, what would the temperature of
the CMB have been at a redshift of z = 5000?

Please explain the theory also. I need to understand the concept. Thank you in advance.
A light of wavelength 620 nm is emitted from 5 Schwarzschild radii from a 20 solar mass black
hole. What wavelength is observed for this light by an observer a long distance away? (The
objects are not moving with respect to the observer)
Astronomers are always seeking to build bigger, more powerful telescopes, which will allow them to study faint galaxies that are very far away. Which of the following is the main reason they're so obsessed with studying very distant galaxies?
Group of answer choices
Light traveled much faster during the early history of the universe, so we can study how the speed of light has changed through time.
Very distant galaxies are more likely to contain planets than the Milky Way is, so we have a better chance of detecting life in those galaxies than we do in our own galaxy.
Since the light from these galaxies took so long to reach us, we're seeing them as they were when the universe was very young.
Strangely, distant galaxies are more like our Milky Way than the Milky Way's `neighbor' galaxies are, and astronomers would like to figure out why this is.
