Quantum physics challenged basic assumptions of physics. E.g. experiments such as “double slit” prove that particles actually behave like waves.
Another key finding was that behaviour of electrons in an orbit is unpredictable, earlier it was thought that electron has fixed path but experiments prove that electron behave like they have “free will”.
This is against the assumption of an existence based on certain laws. There was this debate between Neil Bohr and Albert Einstein:
Einstein wrote: “I, at any rate, am convinced that He [God] does not throw dice.”
To which Bohr replied: Don’t tell God what to do and what not to do.
The same could be traced back many thousand years back as “Swatantrya” Siddhant of Shaivism. “Chaitanya is free for emanation, sustenance and absorption of the universe”.
Why it does so?
Because of its own free will.
(There are many other similarities which can be understood after study of quantum physics).
