Abstract: How to Build a Universe? Physicists looking inward and
astronomers peering outward, have increased our knowledge about the
universe, resulting in new theories & ideas, some good and some
crazy. May be our universe was build out of nothingness or vacuum. Is
this the truth or is it the figment of our imagination? Perhaps the
universe was actually constructed 5000 years, 5000 days or 5 seconds
ago? The answer to these questions is hidden in the nature of the
matter and energy which run the universe. It turns out that what we
and Earth are made of is a tiny fraction of the Visible Matter in the
universe, which is a tiny fraction of the Ordinary Matter (mainly
invisible), which is also a tiny fraction of the not so ordinary
matter called Dark Matter, which in turn is a small fraction of the
(yet unknown) substance called Dark Energy. So why do we seem so
insignificant? Are we? What are all these stuff made of and exactly
how do we measure them? What was the past and what will the future of
our universe be? The lecture will address these questions and issues.
VAHÉ PETROSIAN: Received his Ph.D. at Cornell University (1967) on
subjects related to neutrino losses in stars and on Cosmological
Constant known as Dark Energy. Since 1968 he has worked on many areas
of high energy astrophysics and cosmology. He and Roger Lynds are the
co-discoverers of giant luminous arcs in clusters of galaxies and
gravitational lensing which has proven to be a new and fundamental
method to measure mass in the universe and has led to clarification
of the nature of Dark Matter. Other areas of cosmological research in
which professor Petrosian is involved in are the studies of evolution
of galaxies and active galactic nuclei or quasars. In recent years
his research has been focused on a new acceleration mechanism of
relativistic particles which has found application in solar flares,
gamma-ray bursts, accretion disks and jets around black holes and
even in clusters of galaxies. In collaboration with Brad Efron he has
also developed new and novel statistical methods for analysis of
astronomical data.
