What in the laws of physics differentiates between past and future? Is there a physical reason that time always moves forward? Support the show

Today we explore different interpretations of quantum mechanics, from Copenhagen to the many-worlds hypothesis, in an attempt to uncover what quantum reality really is.Support the show

Some physicists have considered the possibility that dark matter might not exist - and that instead, it's our theories of gravity which are wrong. Today we take a deep dive into these theories of modified gravity.Support the show

You may have heard of the new gravitational wave discovery of September 2020. Here's everything you need to know to understand what this detection means for physics!Support the show

Get introduced to one of the most mysterious characters in physics.Support the show

Here's how a heated debate about whether our Milky Way galaxy is the entire universe led to the discovery of expanding space.Support the show

Learn how the geometry of space defies our intuition, and why it gave Einstein so much anxiety.Support the show

Dark matter has eluded physicists for years - all we know is that it's some kind of matter that doesn't interact with light. Does that sound like a black hole to you?Support the show

Entanglement, wave-particle duality, and uncertainty - here's a breakdown of the weirdest and wildest things about quantum mechanics.Support the show

We revisit some of Dan's early predictions about dark matter, and talk about the biggest dark matter ideas and experiments of the last decade.Support the show
