The Banach-Tarski paradox is one of the most surprising results in mathematics. It says it is POSSIBLE to take a ball, cut it into five pieces, rearrange these pieces and assemble two balls identical to the original. That is, it is possible to create things from NOTHING!
In this video, the Banach-Tarski paradox is explained. We will see how the axiom of choice and the existence of various types of infinity (enumerable and non-enumerable), together with the existence of unmeasurable sets, make it mathematically possible.
The result is also known as the pear and sun paradox, and we talked about the possibility of applying Banach-Tarski to the real world. Is the infinite chocolate bar possible? Are there any physical theories that use Banach-Tarski? Did the universe originate from it?
