Read the Blitzer Bonus attached herewith. The future is now: You have the opportunity to explore the cosmos in a starship traveling near the speed of light. The experience will enable you to understand the mysteries of the universe in deeply personal ways, transporting you to unimagined levels of knowing and being. The downside: You return from your two-year journey to a futuristic world in which friends and loved ones are long gone. Do you explore space or stay here on Earth? What are the reasons for your choice?
If Elon Musk landed on a planet made of antimatter, there would be an explosion and
A. the planet would annihilate (i.e. be converted into energy)
B.
an amount of planet matter equal to that of Elon Musk would annihilate (i.e. be converted into energy)
C. Elon Musk would annihilate.
D. Elon Musk and an equal amount of the planet would both annihilate.
Cruise Ship Enery. Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about l00 million kilograms, and we want to accelerate the ship to a speed of 10% of the speed of light.
a. How Inuch energy would be required? (Hint; You can find the answer simply by calculating the kinetic energy of the ship when it reaches its cruising speed; because 10% of the speed of light is still small compared to the speed of light, you can use thsi formula kinetic energy = 1/2 x m x v2)
b. How does your answer coInpare to total world energy use 5 x 1022 Joules?
c. The typical cost of energy today is roughly 5¢ per 1 million joules. At this price, how much would it cost to generate the energy needed by this spaceship?

Specifically, take the Galaxy at r1 as a New origin and show that Hubble's law is still obeyed.arrow_forwardHubble's First Attempt.

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
