The Schrodinger's cat experiment is the source of many arguments in quantum mechanics, mostly because that was the whole point of it.

Spacetime is the idea that the universe is 4-dimensional, but what exactly is a dimension? Let's get figure it out by making a better spacetime diagram.

E=mc² is probably the most famous equation ever, and it's repeatedly misunderstood. It's not even the whole equation!
