Volume 10

Matt and Jamie dive headfirst into the cosmic foam to explore the Bubble Universe, the mind-bending idea that our universe might be just one of countless “bubbles” in a vast multiverse. From the physics of cosmic inflation and the mysteries of the cosmic microwave background, to the philosophical head-scratchers of infinite realities, they mix hard science, playful analogies, and a touch of pop culture chaos.

#319 Bubble Universe

Andy Saunders joins Matt to talk about his new book Gemini and Mercury Remastered. We dig into the forgotten missions that paved the way for Apollo, the astonishing images he’s restored from NASA’s archives, and the human dramas behind them from blown hatches to dangerous spacewalks.

In this episode, Matt is joined by acclaimed science writer Brian Clegg to explore the dazzling world of the multiverse.  Brian unpacks the science and speculation behind one of physics’ most mind-bending ideas. Together, they discuss why the multiverse has captivated scientists and storytellers alike, the fine line between science and philosophy, and what it all means for our place in the cosmos.   Brian Clegg is expanding our minds and what’s possible in his upcoming title The Multiverse: When One Universe Isn’t Enough (23rd October 2025).

#321 - Brian Clegg - The Multiverse

In this episode, Matt opens with forgotten space hero John Bevis’ birthday and a cosmic musing on relativistic dust, black holes, and the unimaginable energies hidden in tiny things.

Then astrophysicist and author Ethan Siegel joins the show to discuss his new book, The Grand Cosmic Story, a sweeping journey from the birth of the cosmos to the emergence of life and intelligence. Together they explore the importance of critical thinking, evidence, and scientific honesty in an age when misinformation moves faster than light itself.

In episode 323, Matt sits down with filmmaker Mark Craig to talk about his new documentary Apollo 1 the film that revisits the story of Gus Grissom, Ed White, and Roger Chaffee, and the tragedy that reshaped NASA on the road to the Moon.  Mark shares what drew him to the project, the moments that surprised him most during research, and why the Apollo 1 story still matters especially for audiences who know Apollo mainly through the later triumphs.

Philae’s SESAME-CASSE instrument ‘listened’ to the lander’s MUPUS instrument hammer the surface of Comet 67P/Churyumov-Gerasimenko last November. 

Note: Access full description of this audio file via:
http://blogs.esa.int/rosetta/2015/11/12/the-sound-of-philae-conducting-science/

** SESAME-CASSE is the Cometary Acoustic Sounding Surface Experiment located in the lander’s feet in the form of three accelerometers, each of which records acceleration in three directions (one vertical and two horizontal)

** MUPUS comprises the Multi-Purpose Sensors for Surface and Subsurface Science – including the MUPUS penetrator that was activated towards the end of Philae’s first science sequence on 14 November 2014

It was recognized early in the preparation of both experiments that the hammering mechanism of MUPUS, which drives a thermal probe into the comet’s surface, would serve as an acoustic source for sounding the subsurface with CASSE. The determination of the propagation velocity of sound would allow scientists to look at possible layering in the comet’s surface/subsurface materials, important for understanding its evolution.

The CASSE instrument listened to the hammering of MUPUS for 2 hours and 15 minutes. Due to memory limitations, CASSE was not able to take continuous recordings, but only recorded a few seconds in one go. 

A total of 15 hammer strokes were recorded; this audio file contains two signals. The time between the two strokes fits to the charge time of the hammer mechanism expected at that time, thus this particular recording proves that CASSE was really recording hammer strokes.

When recorded, the Philae lander and the comet were about 510 million kilometres from Earth.

This week on our 11th Podcast we cover another exciting week in space. We cover the Soyuz/Progress MS-04 Disaster. Asteroid Mining including an Interview with John Amabile a West Point Graduate and Airspace and Missile Defense Officer in the US Army, who lays out a clear approach for moving mankind into space profitably and with minimal interference from the government in a single human lifetime. We take a look at ExoMars and the TGO.  Astronaut Eye Problems and will USA overtake Russia for the first time with number of rocket launches?
Water on Mars!

#11 - Soyuz/Progress MS-04 doesn't make it and John Amabile - Interview

Cherin

This is a 10-minute live audio excerpt of ESA astronaut Thomas Pesquet and NASA astronaut Shane Kimbrough conducting a ‘spacewalk’ outside the International Space Station on 24 March 2017. They installed a new computer, disconnected a docking adapter to allow its move to a new location and maintained the Station’s Dextre multipurpose robotic hand - among other tasks.

Besides the voices of Thomas Pesquet and Shane Kimbrough, CAPCOM Jessica Meire and PAO Dan Huot can be heard.

Audio is unedited except for normalising. Occasional muting is thus normal.

Space is for everybody. It's not just for a few people in science or math, or for a select group of astronauts. That's our new frontier out there, and it's everybody's business to know about space.
