Dr. Moninder Singh Modgil considers how retro-causality is possible without violating time irreversibility. On a class of spacetime called “hypertorus,” advanced waves of electromagnetism can be interpreted as retarded waves returning to their starting point after circling the closed universe in a single time cycle. This results in all of the spacetime getting causally connected by (sets of) light waves including points having space-like separation. Causality, therefore becomes an equivalence relationship between spacetime events. Non-local correlations observed in EPR type experiments can now be interpreted in this framework. Recurrence metric and Zollfrei
metric are introduced. Next various puzzles of Solar Physics are considered:
1. High solar coronal temperature: while the solar photosphere (the sun’s surface) has a temperature of about 6000 degrees Kelvin, the temperature of the Solar Corona, the tenuous atmosphere of the sun, has a temperature of 1.5 million degrees Kelvin. In the hypertorus universe all the solar energy being radiated away returns to sun after circling the closed S3 universe in a single time cycle. And these incoming fluxes collide with the outgoing fluxes at the Corona, giving such high temperatures, and the presence of highly ionized iron Fe XII, Fe XIII species.
2. Low solar neutrino counts: if the conventional nuclear fusion reaction is going on within the sun, then a specific quantity of solar neutrinos should be detected. However, what is being observed is about 0.3 of the calculated value. Where are the solar neutrinos? Neutrino oscillation is a possible explanation, but makes the neutrino massive.
Dr. Moninder Singh Modgil specializes in the “Godel Universe,” which is a rotating universe solution of Einstein’s field equations. He received his PhD in General Relativistic Physics from the Indian Institute of Technology, Kanpur, India. He did his B.Tech. (Hons.) at the Indian Institute of Technology in Kharagpur, India, in Aeronautical Engineering and has worked on the aerodynamic design of the “Tejas” fighter jet. He has also worked on a collaborative atmospheric project between the Indian Space Research Organization (ISRO) and the National Oceanic and Atmospheric Administration (NOAA) in Boulder, Colorado.
