2,000 “Schrodinger’s Cats” break record for large-scale quantum superposition
https://newatlas.com/physics/2000-schrodingers-cats-largest-quantum-superposition-tests/
The world of quantum mechanics, where particles can be in two places at once or entangled with each other across vast distances, sounds spooky to us living in the macroscopic world of classical physics. But where exactly the boundary between the two lies is still a mystery. Now physicists have blurred the line more than ever before, with a new experiment showing that massive molecules containing up to 2,000 atoms can exist in two places simultaneously.

2,000 atoms is quite big for a particle that obeys quantum laws.
I just had a ridiculous thought. What if quantum laws apply to objects as big as comets when the comets cannot be observed – in distant interstellar space where the density of the gas through which it is passing approaches zero. If it cannot be observed then it could obey quantum superposition laws couldn’t it?
Making that even more ridiculous, what if ordinary matter becomes dark matter by quantum tunnelling if it’s unobserved for long enough. And dark matter becomes ordinary matter when it possesses the chance of being observed. That way, the transition to and from dark matter becomes like puttingnon and taking off an invisibility cloak.
Then the easiest way to discover dark matter would be to leave Schrodinger’s cat alone on its own for long enough and see if it vanishes.
