Weird stuff these quantum effects:
Neutrons could test Newton's gravity and string theory
A Nature Physics report outlines how neutrons were made to hop from one gravitational quantum state to another.
These quantum jumps can test Newton's theory of gravity - and any variations from it - with unprecedented precision.
The "quantum states" of atoms, light particles known as photons, molecules and even objects big enough to be seen have been extensively studied.
They are called quantum because it takes a packet of energy of a very specific size - a quantum - to create the states.
However, of the four fundamental forces, gravity is by far the weakest, and it took until 2002 before gravity's quantum nature was proven. ...
Which reminds me of the question:
Does time exhibit quantum behaviour? Do we experience time as a steady continuous flow, or as discrete jumps?
Does the plank length suggest we can never discern anything finer than a fundamental time step? Yet does that say anything for how time flows for the existence of our universe?...
