Dan Scolnic, a Professor at Duke University and an expert in near-field cosmology, discusses exhilarating advancements expected in cosmology by 2025. He tackles the Hubble tension and its implications for our understanding of the universe’s expansion. Upcoming projects, including the James Webb Space Telescope's findings, promise to shed light on dark energy and the cosmic microwave background. Anticipation builds around new astronomical data and the potential for groundbreaking discoveries that could redefine cosmological models.

A discovery last year reveals our galaxy in a whole new light - except it's not light, it's neutrinos! Learn what this discovery can teach us about the Milky Way and beyond.

Sean Carroll, a renowned physicist and philosopher, dives deep into the enigmatic question of why our universe exists at all. He explores the intricate relationship between physics and philosophy, revealing how both fields challenge and inspire one another. The conversation touches on the concept of 'brute facts' versus necessary truths and delves into Kurt Gödel's theorems, questioning the very nature of mathematical realism. Ultimately, they ponder whether our universe could simply be a brute fact, defying complete explanation.

There has been some criticism of the process scientists use to check each other's work. Today we take a deep dive into peer review to determine how broken it really is.

Dive into the revolutionary Noether's theorem, where symmetries unveil the foundations of conservation laws like momentum and energy. Explore the legacy of Emmy Noether, a trailblazing mathematician who broke barriers in a male-dominated field. Discover how gauge symmetry underpins key principles in particle physics, including charge conservation. The interplay between symmetry and physical laws not only reshapes our understanding of the universe but also highlights the intricate dance of mathematics and physics.
