The traditional conception of the Universe was that objects move on well-defined paths and have definite histories. However it was found in the 1920s that this 'classical' view could not account for the seemingly bizarre behaviour at the sub-atomic scales of existence.
Quantum (subatomic) and 'Classical' (everyday experience) are based on very different conceptions of physical reality.
According to Richard Feynman a system has not just one history but every possible history. Indeed, the universe itself has no single history, nor even an independent existence.
This would appear to violate common sense, but what is 'common sense' but as Einstein said a '...set of prejudices learned by the time you are 16."
