After more than a hundred years of development, quantum mechanics has become one of the most accurate theories. It is not a conjecture theory, but a theory that has been experimentally verified like Newtonian mechanics .
However, because quantum mechanics is so weird that no one can fully understand quantum mechanics so far.
In the field of science, consciousness is not recognized because the object of scientific research is an objective law that does not transfer human consciousness. However, the emergence of quantum mechanics seems to imply that consciousness cannot be excluded, and human consciousness seems to be able to influence the state of the real world.
uses the real world as an example.
You are sitting on the sofa watching TV in the living room, your status is certain, you cannot appear anywhere else, this is our daily life experience, any macro object has a certain position, this certainty is not affected by human consciousness and exists objectively.
But if you are in the quantum world, everything becomes very different, because the quantum world has superposition, that is, everything is uncertain, and microscopic particle can be in two different positions at the same time. For you, you are on the sofa in the living room, but you may also be in other places, such as the moon.
If I want to know if you are on the sofa, there is only one way to do it, that is to observe. When I perform observation behavior, your state collapses into a certain unique state, and you are on the sofa. You might be anywhere before I observe.
Are you completely crazy when you see this? Not only you will be crazy, but also physics tycoons.
Physicist Schrödinger is very disgusted with this weirdness of quantum mechanics, so he proposed the famous thought experiment " Schrödinger's cat " to satirize the uncertainty of quantum mechanics.
Let me briefly talk about this experiment. The experiment itself is very simple, a sealed box with toxic gas cylinders, switches, radioactive element , and a cat.
Whether the radioactive elements are decayed can control switch . The switch controls the gas bottle. When the bottle is opened and released, the cat will be poisoned to death.
Since the decay of of the radioactive element is uncertain, that is, it is in a superposition state of decay and non-decay, the switch is also in a superposition state of on and off. The final result is that the cat is in a superposition state of "both dead and alive".
This is obviously impossible. How can a cat be both dead and alive?
And when we want to know what state the cat is, we can only open the box and observe. And when we observe, the cat's superposition state collapses into a certain state, either dead or alive.
That is to say, our observation behavior will affect the cat's state, and observation behavior will affect the objective world of reality. The result of
has completely broken people's traditional cognition for thousands of years because it implies that consciousness is also participating in the operation of the real world, and our cognition of consciousness still has a long way to go.
