Before the LHC turned on in 2008, many feared that it would create a dangerous black hole that would destroy the world. Were any of those fears well-founded, and how seriously did scientists take these claims? Support the show

Last time, we introduced the biggest open problem in theoretical physics - the problem of combining gravity with quantum mechanics. In this first part of a three-part series, we introduce the leading candidate for how to do that: String Theory.

For the past century, physicists have been building particle colliders as a way to learn about the fundamental laws of physics. Today we talk about why smashing particles together has proven to be such a powerful tool. Support the show

On May 12, 2022 astronomers revealed an image of the supermassive black hole at the center of our Milky Way galaxy. Today we tell the story of what made this image possible.

Just like water changing to ice when it freezes, there were times in the universe's early history when reality changed in almost an instant. Today we dive into these cosmological phase transitions, and speculate about the strange objects these types of instant changes can create.

When cosmology was still an infant science, a daring physicist wrote a theory of the beginning of time.  We revisit this theory and see what value we can still glean from it today.

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. This episode is a rebroadcast of one of our early favorites.

A whirlwind of questions brings us to an odd conclusion: could reality be an illusion created by a quantum fluctuation of a brain?

Here on Earth, we are constantly being showered by particles from outer space called cosmic rays. What do we know about where these particles really come from?

Today we are rebroadcasting an earlier episode all about extra dimensions - How many dimensions of space are there? Could there be extra dimensions that are hidden from view?

Special guest Dr. Diana Powell gives us the lay down on the field of exoplanet research, and on how these recent discoveries may shed light on the question of extraterrestrial life.

Today we attempt to break down the basics of quantum field theory - our deepest theory of physics yet.

Some people like to claim that psychology is just applied biology, which is just applied chemistry, which is just applied physics, and so on. Is there any truth to this? Or is it just our egos getting the better of us?

Dan shares one of the biggest stories of his career - his discovery of an excess of gamma rays at the center of the Milky Way. Is this a sign of dark matter, or is it something less mysterious?

When different groups of astronomers measure the expansion rate of space, they get different answers. Who's right? Or are they both right, and new physics is afoot?

Today we dive into the world's shiny new space telescope - JWST. Learn why are physicists and astronomers are so excited about it, and what new secrets of the universe it might reveal. Keep your eye out for its launch later this week!
