Hartwig Poth, born 21.03.1950 in Heidelberg, Germany, Dipl. Phys., Dr. rer. nat., Patentassessor. I am living in 85521 Riemerling, Germany, and have the email address hupothATposteo.de.
I am interested in gravitation. Therefore I am drafting theories of my own, cf. for a scalar theory Gravitation/Scalar_gravitation/Poth and a four potential theory Gravitation/Four_potential_gravitation/Poth. The four potential theory is better.
Both theories seem to be interesting in themselves - apart from being used for the phenomenon of gravitation.
