Relativity.
Some random key ideas.
1.
In shaping modern cosmology, Galileo articulated the relativity principle in 1632, Newton made gravity universal in 1687, and Einstein revealed gravity as the curvature of spacetime in 1915.
2.
From History: born 1879
Einstein taught us that mass and energy are two forms of the same thing and that gravity is better understood as the curvature of spacetime that guides motion.
3.
Historical belief should rise only as high as the evidence behind the story. Watch for contemporaneous evidence, testimony, and surviving relics.
4.
When thinking about the speed of light, remember that gravity never waits. Light can be delayed by matter, but gravity propagates freely through spacetime.
5.
The universe is likely to expand forever toward a cold, isolated end known as the Big Freeze, but that’s trillions of years from now.
6.
Gravity is universal: every mass influences every other mass, no matter how small.
8.
Sound does not change pitch when it moves to a new medium. Frequency remains constant. Speed and wavelength adjust, revealing a deeper consistency.
9.
Emptiness belongs to philosophy. Physics reveals a universe where a true voids do not exist.
10.
ΛCDM remains the leading cosmological model because our current best measurements indicate gravity is not strong enough to stop the universe’s expansion.
Done. Refresh for another set.
