You could perhaps try making the "Quantum Conspiracy" argument [3]...



1. Take the Many World interpretation of quantum physics, i.e. that
	the world (in some sense) "splits" each time a decision (read
	measurement) is made.[1]

2. Each (measurement of / observation of) movement apparently due to
	gravity causes "splitting".

3. A world exists in which (just by chance) every observation of
	particle motion _appears_ to be influenced by gravity although the
	vast majority of other worlds aren't.



One consequence of this might be that, at any moment, there are
zillions of copies of ourselves finding themselves in the normal
(non-gravitational) universe and being torn apart.
