What are some commonly known facts that are too bizarre for you to believe to be true?
For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some 'organic element' since I couldn't accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

Observation in quantum physics isn't about a consciousness being able to see it happen, but about it interacting with the universe in a way that could potentially be measured. There doesn't need to be a physical observer, just a theoretically measurable result of it interacting with something.
Copied from my other reply because I’m curious what you might think too:
Yea I didn’t convey myself well.
Our ability to observe the effect, at this point in time, results in us disturbing the thing.
Like with Schödinger’s cat, in order to observe the outcome we have to open the box which may result in the poison being released and killing the cat. So if we open the box and the cat is dead, it may be due to our interference rather than the gas being released by the radioactive decay. In order to know the position of the cat, we’d have to be able to see through the box in a way that doesn’t impact the outcome of the experiment. Yet, the cat is either dead or alive, it’s just unknowable to us due to our inability to observe the cat without disturbing the scenario. Only the cat really knows if it’s alive.
Similarly, we largely don’t have great ways to observe quantum happenings because our technology to measure the outcomes disturbs whatever we’re observing. Yet, the thing a we’re looking at either are or are not happening the way we posit, our ability to know doesn’t change that.
Ah, I see what you mean - that the superposition is a model of our uncertainty of unobserved actions, rather than the actual state of the particle. While that was my understanding initially too (because it makes sense) our testing, things like the double slit experiment, has shown behaviours that only make sense if they do occupy both states simultaneously. Quantum computing is actually reliant on qubits being in a 0/1 superposition for it to work. It's what makes the entire thing so maddening, because experimental evidence has disproven every attempt to make it make sense.
First thing my quantum mechanics professor told us was that if you think you understand quantum mechanics you definitely do not understand quantum mechanics. He was at the time one of the world's leading experts on quantum applications, and had just proven the existence of an additional state of matter that quantum theory predicted, and straight up told us to our faces that he didn't understand it, he just knew that it works.
