What fact of nature motivated the development of special relativity?  Explain why Galilean relativity is inconsistent with that fact.

What is Newtonian principle of relativity?

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.

Greetings , I asked this on Bartleby i got a somewhat straight answer . However I was told it was wrong then I asked what makes their answer wrong and not yours(to person who said Bartleby was wrong ) . Please see photos  thanks I'm also having problems with what k subscript 2 = squreroot of 2 m(mass) c^2. That's can't be speed of light it's not in the formula .

Question 6

Choose one practical example or interesting phenomenon associated with the special or general theories of relativity discussed in your text.  Give a brief description of your choice and explain how the relativity theories allow us to better understand the the associated observations.

Please solve the following special relativity question. Please explain each step with details and concepts. This is review for an exam

If the Sun was shrunk to fit the same mass into a smaller volume what would happen to the curvature of spacetime near the surface of the Sun? Spacetime curvature wouldn't change as the mass hasn't changed. Spacetime curvature would stay the same (which we would feel as the same gravity at the surface) Spacetime curvature would increase (which we would feel as an increase in gravity near the surface) Spacetime curvature would decrease (which we would feel as a decrease in gravity near the surface)

What are gravitational waves and how do they work?

Investigate the duality between space and time in Einstein's theory of relativity. How does the theory challenge classical notions of space and time?
