The most boring text ever.
Quantum physics is a subarea of Morden physics about the smallest possible particles in the universe existing in a state of superstition (2 or more forms at once) before being directly destroyed after being observed by a living lifeform. This theorem leads to many new theories like quantum suicide, and the multiverse. The most famous example of quantum physics is Schrodinger’s cat, with the theory that if you put a cat in a box, with poison in it. The poison is linked to an atom and is released when the atom decays. Since when an atom decays is entirely random, if the cat dies or not is pure possibility. If you had shut the lid and did not directly observe the cast, the cat would be both alive and dead at the same time, due to quantum mechanics. Summarised, whenever a something is possible, it is happening, but when it is directly observed and made not possible, the superstition collapses creating a universe where it very well did happen, and one that it didn’t. But certain things can’t be possible, they are always happening. As an example, there is an invisible dragon behind you, about to bite your head off. And according to quantum physics, that IS true, but the chance that when the superstition collapses, it actually ends up in that universe  is extremely low 
Now I will explain what a quantum actually is, they are the smallest possible particles in the universe, constantly fluctuating.
