Hello from 2042!
(A letter from students’ future selves, narrating their lives 20 years after Senior High School Graduation and how the world looks like. There should be an in-depth discussion how the letter was able to reach their present selves by integrating concepts on the Postulates of Special Relativity and their consequences.
Nothing on the different consequences of General Relativity Theory ,What is its contribution to science and humanity?
State and explain the postulates of the special theory of relativity.

- Suppose astronomers discover a radio message from a civilization whose planet orbits a star 35 lightyears away. Their message encourages us to send a radio answer, which we decide to do. Suppose our governing bodies take 2 years to decide whether and how to answer. When our answer arrives there, their governing bodies also take two of our years to frame an answer to us. How long after we get their first message can we hope to get their reply to ours? (A question for further thinking: Once communication gets going, should we continue to wait for a reply before we send the next message?)arrow_forwardWhat 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.arrow_forwardHow do gravitational waves provide new insights into the universe and our understanding of gravity?arrow_forward
- Briefly explain the twin paradox, emphasizing what is paradoxical in the statement and how this apparent paradox is resolved.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_forwardHow 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? From the daily rotation of Earth with respect to distant stars. Counting cycles of oscillation in a cesium atom, the so-called "atomic" clock. From the daily rotation of the Earth on its axis. From the annual revolution of Earth about the Sun starting at noon on one year and ending at noon on the following year.arrow_forward

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_forwardWhat is dark energy?

As we already know, rockets travel at very high speeds.
