Re: [Phys-l] teaching different descriptions of "reality"



Hi all-
Brian Blais writes, in part, with respect to the trajectory of a thrown ball:
> 5) quantum gravity: the ball exchanges gravitons with the Earth,
which influe$> path

Sorry, Brian. This is a complete misconception. "Gravitons" represent the interactions of gravitational waves which are far too weak to perceptibly influence the trajectory of a thrown baseball.
Regards,
Jack
