Quantum physics describes the basic building blocks of the stuff we can see around us. In fact, many scientists over the years have questioned if quantum physics can really be true. Probably the most famous critic was Albert Einstein, who helped to discover quantum physics over 100 years ago but then spent the rest of his life arguing it was incomplete. Nowadays, scientists don’t take Einstein’s ideas about quantum physics seriousl,y and it is widely accepted that superpositions are real – along with Santa Claus. Even if we agree that Santa uses quantum physics to bring gifts to all the children in the world on the same night, we still don’t understand exactly how he does it, the scientists admit.
