- If you are in intergalactic space, calculate the number of CMB photons that you would absorb per second and also calculate the rate of radiative energy absorbed from CMB.a) Why do we believe there is dark matter? b) What important discoveries were madeearly in the 20th century by using RR Lyrae variables?Give examples of nonbaryonic matter.
- The discovery of the dark energy was a surprise because astrophysicists generally assumed that the expansion would be slowing down. Select one: True FalseWhat is the CMB? Group of answer choices A dense region of 4.5 million stars. A large star of 4.5 million solar masses. The cosmic microwave background of photons left over and cooled down from when the universe became transparent 300,000 years after the Big Bang. The space curvature of the universeThe Virgo cluster has a distance of about 17 Mpc from the earth. Using Hubble's law, determine the recessional velocity Vr to this cluster.
