There are two points against your argument:jackle said:I've come into the arguement a bit late here but, on this scale couldn't you consider your electrons to be in a gravitational potential well in addition to an atomic potential well?
This leads me on to think that no two particles will be in the same state due to minor differences in other types of potential unless they are in the same atom.
1. There hasn't been any gravitational effects that has been observed in atomic, molecular, and solid state structures. Gravity, when compared to the electrostatic potential, is so exceedingly weak, that in those areas of study, it is never taken into account as far as I am aware of. There hasn't been any crystal structure grown in zero-g environment that cannot be grown here on earth.
2. If gravitational potential does really come into play, then H2 molecule on earth would behave in a different manner than H2 molecules in space, on another celestial body, etc, whenever the gravitational potential is different. Have you heard of any such observation or correction to any of our celestial observation?
