What is the cosmic microwave background (CMB), and why is it essential in cosmology? What role do instruments like BICEP and the Simons Observatory play in studying the early universe? And is the multiverse real?
I had the absolute pleasure of discussing these questions with Dr. Hugh Ross, astrophysicist and founder of Reasons to Believe.
In our conversation, Hugh and I discuss my research on polarization signals in the cosmic microwave background (CMB), focusing on my work with the BICEP, POLARBEAR2, and Simons Array telescopes. These signals are key to understanding the inflationary event that shaped the early universe. We explore how ongoing data collection helps us learn more about the universe’s origins. I also share a brief overview of my spiritual journey, from a Catholic upbringing to atheism and now being a practicing Jew with agnostic beliefs.
