종려Am I actually insane for studying quantum mechanics just to explain it to you...
First off, quantum mechanics only applies to the microscopic world. So in the macroscopic world we can observe, it literally can't happen.
So, before you observe it, that state is a superposition—aka the red ball and blue ball coexisting state. But superposition only happens when something has wave-like properties, which means while it's flying through the air, there can't be any air friction and no light can touch it either. And how the hell are we supposed to observe that? We observe things by light entering our eyes.

Oh! So you're into quantum mechanics! It's actually super interesting. There's Schrödinger, of course, and then quantum supercomputers, but the most famous one is the double-slit experiment! So first off, a quantum is the smallest unit of matter that can be contained. Now let's get into it! The double-slit experiment shot light particles through two closely spaced slits and got an interference pattern on the screen. But that pattern can only happen if each particle somehow passed through both slits at once, which was puzzling. So they set up a camera under a concept called the "observer" and ran the experiment again. This time, instead of the interference pattern, it just showed up as plain light particles! What this experiment tells us is that when a quantum isn't being observed, it's a **wave** that can pass through two or more slits at the same time, and when it is observed, it becomes the **particle** we're familiar with. But we don't really know its exact form! Because a quantum transforms into a different state when not observed. However, since we do know one of its forms, we say we "both know and don't know at the same time." Applying that hypothesis to a cat, you get a cat that's "both alive and dead"! That's why Professor Richard Feynman said, "Nobody really understands quantum mechanics."
Still want to study quantum mechanics after all this?

You can't know whether the ball in your hand is red or blue until you check it.
