This is something new on our channel where we summarize important scientific topics into one short, bite-sized video, This is the first of hopefully several more to come. I'd love to get your feedback. Thanks for your support!

At large scales, gravity is described by Einstein’s general relativity, where mass and energy curve spacetime itself. At small scales, the universe is governed by quantum mechanics, which successfully explains atoms, p
