We pick up the story of string theory and explore the explosion of interest it experienced in the mid 1980s. For ad-free episodes and other exclusives, join us for $3 a month on Patreon: https://patreon.com/whythisuniverse 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.

Quantum mechanics and general relativity are two of the most successful theories of science ever, but they don't necessarily fit together. Learn why physicists are trying so hard to discover a quantum theory of gravity, and why it's been such a challenge.

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.

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. 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. This episode is a rebroadcast of one of our early favorites. For ad-free episodes and other exclusives, join us for $3 a month on Patreon: https://patreon.com/whythisuniverse Support the show

A whirlwind of questions brings us to an odd conclusion: could reality be an illusion created by a quantum fluctuation of a brain? For ad-free episodes and other exclusives, join us for $3 a month on Patreon: https://patreon.com/whythisuniverse Support the show

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? For ad-free episodes and other exclusives, join us for $3 a month on Patreon: https://patreon.com/whythisuniverse Support the show

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?

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? Support the show

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? Support the show

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! Support the show
