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?
Give four ways to see Einstein's Theory of Relativity in real life. Provide a brief explanation of each and how these impact the life of humans.
What does Special Relativity tell us about physics in Nature?
Pick those that are true.
That energy and mass are equivalent measures of the same thing.
That magnetic forces are really only electrical forces seen in a moving frame of reference.
That we could travel to stars and it would only seem to take days, or less, but it would take speeds nearly equal to the speed of light.
The gravity and electromagnetism are the same thing.

- 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_forwardState and explain the postulates of the special theory of relativity.arrow_forwardIdentify Einstein's two postulates for the Special Theory of Relativity and include evidence that supports them. Include a diagram and relevant physics terminology in your answer.arrow_forward
- Define the theory of relativity? State the two theories of relativity. Differentiate the two theories of relativity. State two features of the Earth that enables life to exist.arrow_forwardWhy do scientists consider Einstein's General Theory of Relativity to be a better theory of gravity than Newton's theory of gravity? a) Newton's theory was never useful, so it had to be replaced by something. b) The two theories always make very different predictions, and only Einstein's theory works. c) Einstein's gravity makes correct predictions in a few cases where Newton's theory does not. d) Einstein's theory is newer, and scientists always prefer newer theories.arrow_forwardHubble'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.arrow_forward
- Give five IMPACTS OF THEORY OF RELATIVITY TO HUMAN and provide brief explanation of how the relativity changed the world.arrow_forwardThe most significant validation of Einstein’s Theory of General Relativity required the observation of stars that appear near the Sun in the sky. Due to the predicted curvature of space caused by the Sun, what were the stars expected to do when the Sun appeared near them in the sky? Why couldn’t astronomers just go out at any time and take pictures of this effect? So what did they have to wait for? Did astronomers validate Einstein’s prediction?arrow_forwardDefine special relativity and give an example.arrow_forward
- How do we define the time interval of one "second" now, and keep track of elapsed time accurately enough to navigate spacecraft through the solar system, or place you on Earth with a GPS receiver? What place in space is our absolute reference point from which we measure distances in physics? If I climb a ladder more than a few feet I am clearly in danger if I fall. Being foolish, I think I can react fast enough to not hit the ground hard if I have more than 1 second to react. How high would that be when a fall to the ground takes 1 second? Hint: The distance of fall is (1/2) a t2, where a is the acceleration of a falling body and near Earth it is about 10 m/s2 for anything.arrow_forwardWhen asked about his thoughts on a new scientific hypothesis, Wolfgang Pauli once said: “That's not right, that's not even wrong.” What fundamental principle of science was he alluding to? And why is the second part of this quote more important than the first?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
