Why This Universe?

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?

Shortly after the Big Bang, space was densely packed with enough stuff for sound to travel through it. What was producing sound in this era, and how can we hear it today?Todays episode is sponsored by the International Space Station.
