Students have asked these similar questions
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.
Hubble's First Attempt. Edwin Hubble's first attempt to measure the universe's expansion rate was flawed because the standard candles he was using were not properly calibrated. Look at (Figure 1)
a.Estimate the value of Ho corresponding to the solid line in the figure. Express your answer kilometers per second per million light-years to two significant figures.
b.What is the approximate age of the universe indicated by that erroneous value of Ho? Express your answer in years to one significant figure.
The 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.
