Question A7
State three pieces of evidence that support the idea that the Universe began in a hot Big Bang,
and explain how each piece of evidence supports the hot Big Bang model. Describe the ob-
servational evidence that supports the idea that the Universe is pervaded by Dark Energy, and
explain why each piece of evidence you cite supports the Dark Energy model.
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.
Suppose we look at two distant galaxies: Galaxy 1 is twice as far away as Galaxy 2. In this case,
A.
Galaxy 1 must be twice as big as Galaxy 2.
B.
we are seeing Galaxy 1 as it looked at an earlier time in the history of the universe than Galaxy 2.
C.
we are seeing Galaxy 1 as it looked at a later time in the history of the universe than Galaxy 2.
D.
Galaxy 2 must be twice as old as Galaxy 1.

- I'm having trouble understanding this. Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about 130 million kilograms, and we want to accelerate the ship to a speed of 12 % of the speed of light. Suppose you want to generate the energy to get it to cruising speed using matter-antimatter annihilation. How much antimatter would you need to produce and take on the ship? Express your answer using two significant figures.arrow_forwardI need help with one circledarrow_forwardFor the graph shown above, a) what quantity would you label the y-axis with if the distance is between galaxies and the Earth? Explain your answer. Think through what we know is happening, motion-wise, out there in the galaxy. b) Also explain why you think there are dots and a solid line, on the graph.arrow_forward
