If you were to take a coffee cup, and break it in half, then in half again, and keep carrying on, where would you end up? Could you keep on going forever? Or would you eventually find a set of indivisible building blocks out of which...

The Higgs Boson. What more need be said?

Proving something right isn’t just about quantity. It’s also about quality and over the years, scientists have made measurements proving that we understand ridiculously well how the universe works.

In this episode, welcome in Matt O'Dowd as the new host to rigorously take you through the mysteries of space, time, and the nature of reality. We're starting off this new season with perhaps one of the most mysterious things of all -...

We've misplaced the building blocks of the cosmos -- and particle physicists like Claire Malone are on a mission to find them. Despite scientists hitting a "major snag" in uncovering what exactly makes up dark matter and dark energy, she...

Since the discovery of the Higgs boson, physicists have searched and searched for any hint of new particles. That search has been fruitless. Until, perhaps, now. Today on Space Time Journal Club we'll look at a paper that reports a...

Our laws of physics are equations of motion, along with some associated constants. We've talked about the symmetries of these equations, and how they lead us to conserved quantities. But this is just the tip of the theoretical iceberg -...

James Beacham looks for answers to the most important open questions of physics using the biggest science experiment ever mounted, CeRN's Large Hadron Collider. In this fun and accessible talk about how science happens, Beacham takes us...

Hank brings us up to date on the latest in the search for the Higgs boson and interviews Fermilab physicist Rob Roser.

Scientists picked up two unusual signals that seemed to be coming up from the ground instead of down from space. They're still working on understanding why, but despite what you may have heard, they aren't evidence for a parallel...

"Rock-star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive project.

With the large hadron collider running out of places to look for clues to a deeper theory of physics, we need a bigger particle accelerator. We have one - the galaxy.

Our fundamental picture of the universe seems pretty nearly complete these days, to the point that some people are suggesting that we’ve arrived at some version of “the end of physics.” And sure, physics is at a turning point, but it...

In 2012, scientists at CERN discovered evidence of the Higgs boson. The what? The Higgs boson is one of two types of fundamental particles and is a particular game-changer in the field of particle physics, proving how particles gain...

Neutrinos are weird. But all the big unsolved problems in physics are somehow connected to one unsolved mystery: Why do neutrinos have mass?

A brief intro to the current theory of (almost) everything - the Standard Model of particle physics. It's like cake, only universal.

Hank talks to some VIPs from CERN about the question on everyone's mind: does the Higgs Boson particle exist? And describes how CERN is going about finding the answer.

Hank interviewed Sergio Bertolucci on October 11, 2011 and Rolf...

No one has ever conclusively seen a proton turn into other, lighter particles, but fifty million liters of water in Japan might change that and our ideas about subatomic particles forever.

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what's all this nonsense of extra dimensions?

Researchers have made some unexpected readings of mysterious particles called muons, which may make us reexamine the Standard Model in physics.

What is matter, anyway? What does it have to do with math? And why aren't you made of Jesus? Delving deeper into the theory of (almost) everything - the Standard Model of particle physics.

What is reality? What is the standard model trying to tell us? Are we living in the 11 dimensions of string theory?



The holy grail of physics is a theory of everything. It may show the...

Is dark matter real? What is dark matter made of?Axions, Wimps, Machos explained. (Part 2 will be "why dark matter may not be matter at all") One of the biggest questions in science is: What is the...

Ask 10 physicists what a particle is: you'll get 10 different answers. Quantum mechanics showed via the Schrodinger equation, that quantum objects are not particles but waves smeared out in space, until the moment...
