Jean-Pierre Petit is a French scientist, senior researcher at National Center for Scientific Research (CNRS) as an astrophysicist in Marseille Observatory, now retired. His main working fields are fluid mechanics, kinetic theory of gases, plasma physics applied in magnetohydrodynamics power generation and propulsion as well as topology and astrophysics applied in cosmology. He is a pioneer in magnetohydrodynamics and has worked out the principle and techniques of parietal MHD converter. In cosmology, he worked on the bi-gravity theory.
Besides his adventure in the UFO topic as well as his assertions about the existence of Ummo, Petit has succeeded in pursuing a scientific career within the CNRS.
Now retired, he is involved with UFO-Science which he co-founded and LAMBDA (Laboratory for Applications of MHD in Bitemperature Discharges to Aerodynamics) which he founded. He claims a true scientific study of the UFO phenomenon would improve our scientific knowledge and help mankind.
