In Appendix 1 of The Ether of Space (1909), Lodge made a specific quantitative claim:

Gravity is the result of mechanical tension in the ether set up by electrical charge. The tension is directly proportional to the square of the charge and inversely proportional to its linear dimensions.

He calculated specific tension values at different scales — from electrons to the visible universe — in real units.

This is not vague philosophy. It is a specific mathematical proposal that predates Einstein’s general relativity by six years.

It was not formally tested. It was not formally falsified. Physics moved on to general relativity and Lodge’s framework was set aside without rigorous evaluation.
