Measuring propagation speed of Coulomb fields

Marcello Piccolo (LNF)

8 Novembre 2017 @ 11:00 - 13:30

In planetary systems, the problem arises whether gravity attracting the planets towards the central star has an instantaneous action or propagates with finite velocity. Laplace noticed that, if gravity propagated with finite velocity, planets motion would become unstable due to a torque originating from time lag of the gravitational interactions. Given that equations describing gravitational …
