It is not clear what relationships you are talking about. If you mean gravity, that was basically discovered by Sir Isaac newton, but then it took a while longer to find out how far the stars are from us, and to confirm the gravitational attraction between them.

The relationship between a star's temperature and brightness was discovered independently around 1910 by Ejnar Hertzsprung and Henry Norris Russell. The relationship between these to parameters is depicted in a Hertzsprung-Russell diagram or H-R diagram.
This relationship was discovered by Karl Georg Ohm.
The relationship between electricity and magnetism was discovered by the scientist Michael Faraday in the 19th century.
