13 Subatomic Stories: Why general relativity is definitely right

From the creator

Of the known fundamental forces, gravity stands out. Rather than being caused by force-carrying particles jumping between matter particles, gravity can be explained as the bending of space and time. In episode 13 of Subatomic Stories, Fermilab’s Dr. Don Lincoln briefly sketches Einstein’s theory of general relativity (our current theory of gravity) and mentions some tests that prove that it’s right. Can leptogenesis explain why there’s something instead of nothing? https://www.youtube.com/watch?v=PsqEcGMjEfo Relativity: How people get time dilation wrong. https://www.youtube.com/watch?v=svwWKi9sSAA Length contraction: The real explanation https://www.youtube.com/watch?v=-Poz_95_0RA Fermilab physics 101: https://www.fnal.gov/pub/science/particle-physics-101/index.html Fermilab home page: https://fnal.gov Andromeda image: Adam Evans Galileo constellation image: ESA - J.
