Why This Universe?

Physicists Daniel Baxter and Alexandra Rahlin discuss their experiences collecting data in extreme locations, such as deep underground in a mining facility and from the South Pole. They explore topics like working with dark matter, the challenges of conducting experiments in remote locations, the use of duct tape and zip ties for scientific purposes, and the psychological challenges of living in isolation without sunlight. They also reflect on the awe-inspiring nature of studying the universe in extreme locations.

Explores the geometry of space and its relation to Einstein's theory of general relativity. Delves into the concept of Euclidean and non-Euclidean space, highlighting their differences. Discusses non-Euclidean geometry and its connection to physics, including how it relates to Einstein's theory of relativity. Explores Einstein's theory of general relativity and how it revolutionized our understanding of gravity. Explores the concept of a finite universe and Einstein's solution.

Historian Aviva Rothman discusses the Copernican Revolution and its impact on society. Topics include the transition from Earth-centered to sun-centered cosmos, Tiko's myths and Kepler's beliefs, Kepler's geometrical universe, parallels between Copernican and Darwinian Revolutions, lessons from the history of science, Aviva Rothman's book, merchandise, and support options.

Physics professor and musician, Tim Cohen, joins the hosts to answer questions about the physics of music. They explore the 12-note scale, overtones in instruments, the physics of rhythm, the connection between number theory and music, and the physics of musical instruments like the flute, organ pipes, and saxophone.

The podcast explores the development of the Universe's structure, starting from the Big Bang. It discusses the cosmic microwave background and its consistent temperature, revealing density variations and the role of gravity. The significance of dark matter in formation is explored, along with the differences between hot and cold dark matter and their impact on structure formation.

Why This Universe hosts it's first ever live episode taping featuring guests Daniel Holz and Diana Powell. We discuss the possibility of intelligent life out in the Universe, the existential risks faced by humans on Earth, and the chance the intelligent life can persist in the Universe.This conversation took place during the University of Chicago Podcast Network festival.For access to ask-us-anything segments and other exclusives, join us for just $3 a month on Patreon: https://patreon.com/whythisuniverse.Support the show

While physicists overwhelmingly agree about the existence of dark matter, a select group of people aren't convinced. Instead, they believe we must be wrong about gravity, and claim we need a theory of modified gravity (MOND) instead. Recent press releases have claimed "smoking gun" evidence for this underdog theory, should we take them seriously?Did you know this episode was inspired by a Patreon question?
