Why is quantum theory so strange? The weirdness could be in our heads

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.
#
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.
#
We don’t know the extent to which it can or should apply to macroscopic objects.
#
“Whatever that underlying reality turns out to be, it is almost certainly ‘strange’
relative to our classical experience,”
