Does the Universe Bounce? A Conversation with Anna Ijjas (#236)

Was there a Big Bang? Did the universe emerge from a singularity?
Is there any evidence for a Multiverse? Anna Ijjas and I explore
these questions and much more, including her incredibly fascinating
work on bouncing cosmological models. Anna Ijjas is a research
faculty at New York University. Her research lies at the
intersection of gravitational theory and cosmology. She has
pioneered the application of mathematical and numerical relativity
to cosmology with the goal of developing novel theories that
explain the origin, structure and evolution of our universe. Her
work has already led to several advances in this new field,
including the establishment of slow contraction as a rapid and
robust smoother. Currently, she is developing novel mathematical
and computational methods for studying the effects of modifications
of Einstein's relativity theory on cosmology and black holes. Her
Website: https://anna-ijjas.com/ Topics discussed include: What
should a theorist know about experimental cosmology? Why is the
cyclic universe theory not often taught and often ignored? The
Friedman Equations. What is geodesic complete? Some alternative
theorems. Inflation and scalar fields. Quantum fluctuations in the
scalar field. About the Hubble Tension! What's Anna's take? What
should we be teaching young cosmologists? Watch my most popular
