huh?!? there are GR corrections to Newton which include terms like 1/r^3 iirc
- ahazred8ta 2y agoThere are (ȓ/r^3) terms involving unit vectors, but that works out to 1/r^2 in practice. There are cubed terms in string theory and Quantum General Relativity (QGR) / Loop Quantum Gravity, but these do not apply at macroscopic distances. If you know of a url link to a non-theoretical inverse-cube effect which has actually been confirmed in lab experiments or actual observation, please post it.
- Iwan-Zotow 2y agoHuh!?! Classic GR test of Mercury periphelon precession is mainly due to inverse cube correction to Newton
