⚫The intoxicating Katie Freese has a new ingredient for her Cosmic Cocktails, Dark Stars! ⚫

Hello, Impossible listeners!

We have some cool content from our latest episode featuring my
esteemed colleague, Prof Katie Freese. Katie shares groundbreaking
revelations about evidence of her novel idea — so-called ‘dark stars’.
Here are some of the highlights from this exclusive episode:

⚫ Dark Stars Unveiled: Delve into the mysterious world of dark stars,
which can grow to be a million times more massive than the sun and a
billion times brighter!

🔭 Observations with the James Webb Space Telescope: Learn about how
data from the JWST has revealed potentially two galaxies that may
harbor massive dark stars, along with the ongoing analysis to
differentiate them from galaxies with later generations of stars.

💡 Theoretical vs. Experimental Physics: Get insights into the
interplay between theory and experiment in cutting-edge physics, as
Katie Freese and host Brian Keating discuss the expertise needed for
experimental aspects and theoretical minimum for new grad students.

🧠 The Philosophy of Cosmology: Explore the philosophical and
theological implications of cosmology, the multiverse theory, and the
role of cosmologists in understanding the origins of the universe.

🌌 Cosmic Discoveries: Uncover the latest theories and observations,
including Katie Freese’s work on the early universe, dark matter
impact on the formation of the very first stars, and modifications to
Einstein’s equations.

🌟 Public Outreach: Gain an understanding of the importance of public
communication for scientists, the need for scientific education among
the public, and Katie Freese’s efforts in creating a course on public
speaking and communication for scientists.

Until next time, have a M.A.G.I.C. Week!

I had the pleasure of sitting down with my friend Jordan Peterson to discuss some of my favorite topics, including Olber’s Paradox and what Edgar Allen Poe has to do with it.

Katie Freese on the questions of ‘is there a God’ and ‘the origin of time’:

“In my heart, I believe all these things are physics questions, and that we’ll get somewhere with them.”

Let’s pretend for a minute that the Big Bang took place in an instant. And then let’s pretend a being in another galaxy witnessed it. I asked my favorite generative AI Artist, DALL-E, to imagine what that would look like.


Katie Freese is wonderful!

Katherine Freese is a renowned theoretical physicist, professor of physics at the University of Texas at Austin, and a member of the Simons Observatory. She works on a wide range of topics in theoretical cosmology and astroparticle physics, including her quest to identify the dark matter and dark energy that permeate the universe. She wrote The Cosmic Cocktail: Three Parts Dark Matter, published in June 2014 by Princeton University Press.

She is one of the most renowned scientists that exists today, and I’m excited to have her back on the show to discuss Hubble tension, natural inflation, dark energy, and, of course, the star of the show (pun intended), dark stars!
