PARTICLES that also act like waves; the “spooky action at a distance” of entanglement; those dead-and-alive cats. Small wonder people often trot out physicist Richard Feynman’s line that “nobody understands quantum mechanics”. With quantum theory, we have developed an exceedingly successful description of how fundamental reality works. It also amounts to a full-frontal assault on our intuitions about how reality should work.
Or does it? “It only seems strange to us because our immediate everyday experience of the world is so very limited,” says Sean Carroll at the California Institute of Technology. Intuitive-feeling classical physics is largely devoted to describing macroscopic objects – the things we see and feel directly in the world around us. “It should not be surprising that this breaks down when we push it into domains that we never experience directly,” says Carroll.
There is a big difference between seeming strange and being strange, too. “If quantum mechanics is right, it can’t truly be strange – it’s how nature works,” says Carroll. You can say something similar, after all, about other areas of physics, such as Albert Einstein’s space-and-time-warping theories of relativity. Their effects only truly kick in at close to light speed, or in humongous gravitational fields of the sort, we never experience, so their picture of the world seems alien to us.

👌👌👌✒It’s so easy to admit that everything in the world has a state. It is the ball behind us that has all the colors of the world, moves at all speeds at once, changes its state, and in the end we are able to describe it only when we see it. It’s the same with the quantification of an idea … we spin conspiracies who could do something for us, we think about how others talk and think about us …. I’m reconciled to the fact that everyone is like that ball and until the moment of seeing her I do not know anything. This is our real and definitive limit of knowledge
