lesson 10

This lesson is one of the best ones as there isn’t much information to digest and he talked quite slowly, which was clear for me. I wish that this could be applied to all other lessons as well which would aid me in receiving more information as I’m slow at typing information into my notes, and writing in a notebook was not an option as I had to put it on the google site. Inventions that need the sky need to watch the time since time dilation exists.

notes
time dilation is the slowing down of a clock as determined by an observer who is in relative motion with respect to that clock in the theory of special relativity. Time dilation was actually first found by Albert Einstein in 1907 as a consequence of special relativity in accelerated frames of reference. Time dilation can be inferred from the observed constancy of the speed of light in all reference frames dictated by the second hypothesis of special relativity. Gravitational time dilation occurs because objects with lots of mass create a strong gravitational field. The twin paradox is a closely related phenomenon predicted by special relativity. Velocity and gravitational time dilation have been the subject of science fiction works in a variety of media. Time reversal in physics is the mathematical operation of replacing the expression of time with its negative in formulas or equations so they describe an event in which time flows backwards or all motions being reversed. The basics of time inversion is that someone in the future invented some doodad that allows time to flow backwards.
