Take a run of the mill graviton detector: (Not yet built, nor would they be easy to build!).

Put it on a table top, on this planet. Say its detecting 1,000 gravitons per second. Now pull the table out – quickly but smoothly. How may gravitons will it see on its 0.5 second trip to the floor?

The answer is none. Or about 500, or ‘don’t ask’.

According to the equivalence principle: When it drops off the shelf, it is supposed to stop seeing gravitons.

According to QFT – the device is still in a gravitational field, so it will see about 500 gravitons on its half second journey. Note that the speed of the detector has not changed appreciably when it first starts to fall. “All experimental quantities are unchanged”.

This simple thought experiment lies at the
