Poplawski, Nikodem
Senior Lecturer and Physics Coordinator
Arts & Sciences

    Nikodem Poplawski joins the University of New Haven after serving as a visiting lecturer at Indiana University Bloomington, where he taught undergraduate physics (mechanics, electricity and magnetism). He received his Ph.D. in theoretical physics from Indiana University and his M.S. in astronomy from the University of Warsaw (Poland).

    Dr. Poplawski is interested in the nature of gravity and spacetime, the origin and composition of the Universe, the nature of fields and particles, and quantum gravity. His research focuses on how gravity with spin and torsion can solve fundamental problems in cosmology. He proposed that torsion causes the formation of a new universe through a big bounce in every black hole and that our Universe is the interior of a black hole existing in another universe. This scenario was listed by National Geographic and Science magazines among their top ten discoveries of 2010. Dr. Poplawski also appeared in Curiosity on Discovery Channel, in an episode hosted by Morgan Freeman: Parallel Universes – Are They Real?



    Theoretical gravitational physics and cosmology:

    • General relativity, Einstein-Cartan theory, gravity with spin and torsion
    • Origin of Universe, big bounce, black holes, wormholes, arrow of time
    • Antimatter, dark matter, dark energy
    • Spacetime, fields and particles, quantum gravity, unified field theory
