Physics Colloquium with Jan Loeber

Jan Loeber will present at this week's Physics Colloquium. Loeber's presentation is titled "A New Take on Gravity".

The seminar will be presented at 4:00 p.m. on Thursday (Oct. 15) in Fisher 139. The coffee hour will be held at 3:30 in the Fisher Hall Lobby.

Abstract This talk explores a conceptual alternative to conventional models of gravity and cosmology, beginning with the induced-gravity model proposed by W. Stanley and G. Vezzoli, in which gravity emerges from the collective effects of external neutrinos interacting with matter. The model provides a different perspective on gravitational attraction, inertial mass, and atomic structure by considering neutrino collisions, interaction cross sections, and the “shadowing” effects produced by massive bodies. Building on this framework, the talk develops a broader conceptual model of a cyclic, potentially infinite multiverse. In this picture, universes evolve through stages of expansion, stellar and galactic evolution, matter aggregation into black holes, and the eventual dissipation and interaction of matter and antimatter on cosmic scales. Collisions between massive black holes and their antimatter counterparts are proposed as possible mechanisms for initiating new universes without requiring an initial singularity. The presentation is intended to be interactive and exploratory, examining where humanity fits within the cosmic continuum and considering fundamental questions about matter, antimatter, neutrinos, gravity, black holes, cosmic evolution, and the possible origin and fate of universes. The proposed model is presented as a conceptual framework for discussion rather than as an established replacement for general relativity or the standard cosmological model.

Bio Jan Loeber earned a B.S. in Physics from Michigan Technological University and an M.S. in Business Administration from George Washington University. He had a distinguished career in telecommunications, serving in executive positions at companies including Nokia Americas, Unitel UK, and GTS Carrier Services. After retiring, he founded Surgent Networks and became active in technology startup investment. He has a continuing interest in physics and astrophysics and is the author of The Radical New Theory of Gravity.
