The recently popular formula concept Bell's inequality

That is, experiments related to quantum entanglement

After watching some videos
Although I still don't quite understand the meaning of this Bell's inequality

(Picture: Scientific problems require scientific methods to verify)

But it also proves one thing

That is to say, the collapse of the state of these particles
is indeed determined by observing what happens at the moment
rather than after the particle is produced

(Picture: Quantum entanglement was not initially decided)

That is to say, the real world
is related to our observation

But in fact, this observation
does not refer to human observation
, but refers to the observation of interaction with other electromagnetic waves (collapse is not necessarily called naked eye observation, but interaction with other energies)

For example, the electromagnetic waves observed in the experiment
How to detect is also the result of relying on the impact of electromagnetic waves
Because we cannot directly observe these changes with the naked eye

So we can only infer what the resulting phenomenon looks like based on another phenomenon
Therefore, there is no problem that the moon does not exist because we are not looking at the moon
Because the moon is always due to We and even the entire solar system are interacting

So
Maybe in some places in the universe
even light or even a little bit of electromagnetic wave does not pass through that place
Maybe it can really be called a non-existent place

Because there are no observations
