If the theory of quantum mechanics is right, does it mean that life is really meaningless?

If quantum theory is completely correct. Then god also exists. Since God exists, life is naturally meaningful.

Then I will answer your question with what I have seen and heard.

Quantum mechanics holds that a person's state or his physical system is just a bunch of wave functions. It can be said that you may be invisible to the big physical system of the universe. If you are not seen, you will not leave any trace on the world boundary. Here comes the idea of human soul, which dimension the soul exists in has not been decrypted so far. Quantum theory holds that when you are observed, your soul is projected into a three-dimensional world through other people's dimensions, so it exists. But we are not observed by things other than human beings, so we don't exist, so the problem in the problem arises.

But I read this passage from a book:

When you can't see the moon with your back to you, the moon is just a wave function, so the moon doesn't exist. It will only appear when you turn around and look at it, and determine its specific position and shape. Here it is definite, not fixed.

Experts in quantum mechanics believe that the process of "measuring the position of the moon" itself will have a huge impact on the physical system where the observed object is located, resulting in a random state rather than an accurate value. Because in the current world framework, everything is like a big net, and they are all interrelated. Once the "measuring" end changes, the measured end in the same physical system will also change.

If quantum mechanics is completely correct, we can find that there is a "hand of God" at this time, observing our world in an invisible dimension, which may also be our "dimension of soul existence" and may do something that cannot be explained by existing science.

For example, there are two people in the room, and you are so absorbed in one thing that you forget that there is another person next to you, and this other person has packed up the things in the room, so you can take it as a non-existent person. You will be surprised when you look carefully, because you know this person clearly, but when you concentrate on your work, the whole physical system is static relative to you, and the surrounding objects and your physical system are static, but when you turn around, you find that the position of things has changed. Don't worry, take your time. Maybe at first you don't think this example makes sense.

Let me give you another simple example. We often put something somewhere when we are alone, but when we look for it for the second time, we find it is not there, but somewhere else. For example, we clearly remember to put our exercise books in our schoolbags, but we can't find them when we get to school. This will make us doubt our memory, but what if "God" moves behind us? You can't see god.

Therefore, if the theory of quantum mechanics is completely correct, then God exists.
