Most people are aware of the twin paradox, schrodinger's cat, and the double slit experiment. What are some of your favorite, lesser known, counter intuitive facts or thought experiments about physcis?
Banach Tarsky paradox is the most insane paradox in the entire history of insane paradoxes and I’m certainly not smart enough to summarize it or do its justice but it’s something to the effect of take a sphere, cut it in two and you can make another sphere out of the two pieces that’s twice as big with no hollows in it.
But that's more a mathematical paradox is it not?
There is no way such sphere could ever be cut up in that manner.
Idk maybe something similar happens at the singularity of a black hole but that just speculation.
Uh no schrodingers cat though originally intended as a criticism of quantum mechanics is an analogy for superposition which is a very much so real thing that happens within the atomic to subatomic scale range.
