Title: Was there any beginning to the universe?
Speaker: Dr. Ali Nayeri
In J.J Abraham’s Star Trek reboot, a Romulan destroys the planet Vulcan. But actually it was Einstein that wiped it from existence. In reality, Vulcan was hypothesised to account for anomalies in the orbit of Mercury based on Newton’s theory of gravity. But Einstein’s new theory of gravity, General Relativity (GR), gave corrections that could account for these anomalies without supposing the existence of the hypothetical planet. It was the first of many signs of the supremacy and importance of GR. In 1922 the Russian cosmologist Alexander Friedman suggested GR implied a dynamic universe that is either contracting or expanding. But Friedman died in 1925, mostly ignored. In 1927 Lemaitre developed a similar idea implying the universe originated from a “primeval atom”. In modern terms the initial singularity is where space-time curvature, pressure, temperature and density are all infinity. Continuing the evolution of the universe before the singularity is impossible so it represents the beginning of time. Two years later Hubble seemed to find evidence consistent with Lemaitre’s model. But did the universe really begin to exist or was there a before the Big Bang? Only a thorough understanding of gravity can resolve this ultimate question.
About the speaker: After receiving his PhD in Theoretical Physics in 1999, Dr. Ali Nayeri, was appointed as a Postdoctoral Associate at the Department of Physics at MIT for two years and as a Research Fellow and Lecturer at the MIT Center for Theoretical Physics for an additional year.
He then joined the Harvard Physics Department in Cambridge. Currently Dr. Nayeri is an assistant professor and member of the Chapman Center for Quantum Studies. Dr. Nayeri is a member of the prestigious Kavli Institute for Theoretical Physics in University of California, Santa Barbara and the Department of Physics and Astronomy at the University of California, Irvine.
Dr. Nayeri’s fields of research include, string and brain cosmology, early universe and inflation, general relativity, statistical physics of semi-classical theory of quantum gravity, and alternative cosmologies. He has published numerous papers in various scientific journals in the US, UK, Europe, Netherlands and Russia. Dr. Nayeri is also among the top 100 Iranian-American Scientists and he has been chosen for Marquis Who is Who in America, 2008-2011. He is amongst the few physicists who have been chosen by the American Mathematical Society to act as the reviewer of the mathematical papers.
