Quantum mechanics were discovered through Schrödingers cat. A cat was put in a box with poison to be released at any time. There was no way of knowing the cats state so it was both alive and dead. It's basically being two contradicting states at a time
Lol no, it's called superposition. Einstein called it "spooky communication at a distance" because it can be used to transfer information faster than the speed of light via entangled electrons.
Ah, the models are:
The point particle (outdated) which treats every particle as an x,y,z point in space
And string theory which is still being developed and is the potential theory of everything.
Ye, I've only been studying for like 3 quarters of a year and I'm only 13 but my dad forced me to watch it and then this really cool science chanel which made it 10x easier to understand got into my recommended.
