Indranil Banik is a physicist at the University of Portsmouth who
studies λCDM cosmology, the standard model of physics that tells
us the Big Bang happened, that it happened something like 13.8
billion years ago, and that the modern universe is replete with
undetectable cold dark matter (the CDM of the theory). Listeners
of the show will know that there are compelling reasons to
believe that these conclusions are based on questionable
assumptions at the very heart of physics. This conversation,
between a liquid sun proponent, a scientist who has spent his
career studying the mainstream, and an appreciator of finely
crafted theories, is an opportunity to lay these questionable
assumptions on the table and to see how they hold up to scrutiny.
Dr. Banik is also an invited speaker at our Beyond the Big Bang
gathering in Portugal this summer, and has graciously agreed to
serve as a counterbalance to those who say that the Big Bang
Theory doesn’t have much life left in it. National Astronomy

https://bit.ly/3v3kz2S PODCAST INFO: Anastasia completed her PhD
studying bioelectricity at Columbia University. When not talking
to brilliant people or making movies, she spends her time
painting, reading, and guiding backcountry excursions. Shilo also
did his PhD at Columbia studying the elastic properties of
molecular water. When he's not in the film studio, he's exploring
sound in music. They are both freelance professors at various
universities.
