Lets say I make 2-slit interf. experiment with slow (low enegry) electrons. I make their path as long as possible so they have time to fall in the Earth's gravitational field while they are flying.
So electrons are attracted to the Earth, hence the Earth is attracted to the electron beam. Even it is far beyond the precision of any experiment, it can give a 'which path' info and break the interference.
However, all experiments are made in the Earth's gravitational field, in our slightly curved space-time and it seems that it does not affect the experiments
As an ultimate example: can an interference pattern be obtained from a gravitational lensing? Depending on the path, the central body is attracted to the right or to the left...
