Dr. Sarah and Dr. Danica Marsden are here with me in Seattle, Washington for our live show at the AAAS! We talk about how quantum computers do their quantum computer thing. Our guests are Old friends of the show: Matt Sheehy (from Lost Lander), and Brent Knopf (From Ramona Falls and El VY)

Our Guest Today is Ted Leo, of "Ted Leo and the Pharmacists" Fame. Our experts today are Dr. Danica Marsden and Dr. Stephanie Simmons. Our topic is QUANTUM COHERENCE and DECOHERENCE: how a quantum superposition will not stay that way forever. The Environment will start asking it questions until our system loses coherence.

The topic of this Episode is O-type stars, the biggest, brightest stars in the universe! Astrophysicists Dr. Benjamin Brown and Hannalore Gerling-Dunsmore break it all down for our guest Ryan North (of Dinosaur Comics, and Squirrel Girl).

Today's guest is a marvel! It's the host of the Drabblecast: Norm Sherman! Norm joins Dr. Ken Clark and Dr. Katelin Schutz, experts in dark matters. today we talk about dark matter candidates: our best guesses for what is causing the crush we feel but cannot see.

Andray Domise joins Dr. Sabine Stanley from Johns Hopkins University and Erin Wenckstern from the Weather Network to learn about NEPTUNE! Home to the fastest winds in the solar system, where it rains diamonds, and mysterious "superionic water," the ice giant slowly trudges around its orbit, the farthest planet from the sun!

Humorist and Podcaster Benjamin Ahr Harrison (Greatest Generation, Friendly Fire) Join me and Dr. Joey Shapiro Key and Dr. Jocelyn Read to talk about THE NEXT GENERATION of gravitational wave detectors: LISA (the Giant Tumbling Space Triangle) and NANOGRAV our pulsar timing array system!

Adal Rifai from "Hello From the Magic Tavern" joins us to talk about the first PHOTOGRAPH of a black hole by the Event Horizon Telescope. Our guide through this amazing story are Dr. Leo Stein and Dr. Katie Bouman. We learn the basics of Black holes, and the interferometry performed by the Event Horizon Telescope, and then about the complicated image processing which needed to be done to interpret all of that amazing, messy data!

Particle physicists Dr Erica Caden and Dr. Ken Clark are my physicists today. Our guest today is Author, musician, composer and novelist Cecil Castellucci. Today we're talking about the MinniBooNE experiment and the possibility of Sterile Neutrinos.

Dr. Katie Mack and Dr. Robert McNees team up to explain the heat death of the universe to Award Winning Author Ken Liu.

A supermassive blackhole at the centre of a galaxy can cause the gas that falls into it to glow SO BRIGHT that it stops the creation of new stars. What? How? Courtney Brooke Davis is here to ask the questions! Dr. Victoria Scowcroft and Dr. Carolin Villforth are here to give the answers! and I'm here to talk about pudding.
