- 1. Which of these is true about the Big Bang model? Â a. The singularity is an established, well-defined part of the model. Â b. Cosmic expansion stopped at some point in time. Â c. Part of its proof is the amounts of H and He we have in the universe today. Â d.

(Like the solar system, Saturn's ring, black hole accretion discs) Let's focus on our galaxy. Originally, the galaxy was a huge spherical cloud of gas and dust, much larger than it is today, and rotating much more slowly. Explain using gravity and the conservation of angular momentum, why the galaxy today is a flat disc that rotates faster.arrow_forward
- There is still some uncertainty in the Hubble constant. (a) Current estimates range from about 19.9 km/s per million light-years to 23 km/s per million light-years. Assume that the Hubble constant has been constant since the Big Bang. What is the possible range in the ages of the universe? Use the equation in the text, T0=1H , and make sure you use consistent units. (b) Twenty years ago, estimates for the Hubble constant ranged from 50 to 100 km/s per Mps. What are the possible ages for the universe from those values? Can you rule out some of these possibilities on the basis of other evidence?arrow_forwardWhat is Lorentz law? Give definition, background, uses and examples of it.arrow_forwardThe law of conservation of energy states that energy can be converted from one form to another but cannot be created or destroyed. Therefore, the amount of energy in the universe is constant. In your initial post to the discussion, respond to the following prompts: What do you think would happen if energy were not conserved? Think of (and share) two scenarios in which our lives would be drastically altered if this law of conservation was not in place. At least one of your scenarios should be at the molecular level. Would the implications be positive? Negative? Explain.arrow_forward
