Portable imaging rigs are all the rage right now.  Ultra portable wide field imaging dominates starparties and new moon weekends!  WE look back to when Steve and Trevor got into the weeds and with portable.

Why do people see faces in the Moon? And what actually causes these lunar features?

7/7/25 - The Man in the Moon

The Big Bang is the reigning explanation for our universe’s origin—but what if it’s wrong? This episode dives into cosmic controversies and the theories that challenge everything we thought we knew.

What If the Big Bang Never Happened?

What If the Big Bang Never Happened?

Perhaps the strongest evidence we've ever acquired in support of the Big Bang has been the discovery of the leftover radiation from its early, hot, dense state: today's cosmic microwave background, or CMB. While there were many competing ideas for our cosmic origins, only the Big Bang predicted a uniform, omnidirectional bath of blackbody radiation: exactly what the CMB is.

But it turns out the CMB encodes much more information than just our cosmic origins; it allows us to map the very early Universe from when it was just 380,000 years old, and gives us vital information about what has happened to light from that time over its 13.8 billion year journey to our eyes. It encodes information about our cosmic expansion history, about dark matter and dark energy, about intervening galaxy clusters, and about the material here in our own galaxy, along with much more. It is, arguably, the richest source of information from any one single observable in our entire Universe.

Here to guide us through what CMB scientists are working on here in 2025, including what we've learned and what we're still trying to find out, I'm so pleased to welcome Dr. Patricio Gallardo to the show. We've got more than an hour and a half of quality science to go through, and by the end, I bet you'll be more excited about the upcoming Simons Observatory, designed to measure the CMB to higher precision than ever before, than you knew you should be. Enjoy!

Forget tentacles—what matters is the mind. We explore how alien behavior might emerge from evolution, culture, and technology, and why our biggest first contact risk may be misunderstanding.

How Would Aliens Behave? (Narration Only)

This song praises the beautiful interrelatedness of everything, and the expression of that unity through individual actions and/or the scientific, symbolic, and/or metaphorical systems of alchemy, astrology, and/or astronomy.  Or, maybe it’s just a cool song on your playlist.

This SoundCloud is my Project Freeman Music 'Works In Progress' Platform.
Here are all the Demos I've captured of my Compositions to date, including my 'Songs of Freedom', which are categorised as Relating, Realisation, Remedy & Rebellion (and Revelry!) on the 'Road to Redemption', from Serf to Self, from Slave to Sovereign. 
The demos are of various quality, from the early 90's Gregorian to the present day... 
PLUS here I share audio of 'Project Freeman' presentations and interviews (these are more like podcasts, but some also include songs) 

The songs start off as rough demos in various playlists here, and are then added to the 'Project Freeman Music Official Releases' playlist once they are finished, recorded and released to the major music platforms. (You can get your own copies of these via my Bandcamp link below, with all proceeds going to support my work and causes).
Therefore the quality of the demos here varies enormously, from old 1990s amateur recordings on cassette tape, to amateur home studio demos, to raw acoustic demos on the road in the camper van, to overdubbed tracks on the move, to more polished finished works etc etc

I have over 200 songs at various stages of production. My aim is to gradually publish my complete catalogue online, so the main thing here is to 'hear how the song goes' not to be fussy about the quality of recordings or performances.
Also, 'Tracks' have not been shared here in any particular order, so more recent Tracks could actually be much older, poorer quality demos and it's not possible to change the order of the Tracks once they have been uploaded, so please bare all this in mind when listening to 'Tracks'. It's probably best to choose a 'Playlist' and go from there :)

If you're looking for the best quality versions of the songs please go straight to the 'Project Freeman Music Official Releases' playlist

Lastly, THANK YOU FOR LISTENING!
Us amateur, unsigned artists don't have big budgets behind us to promote our works so I'm very grateful to you for stopping by my little corner of the internet and checking out what I'm up to ;)
The best gift you can give a song writer is to listen to their creations, so please know that I very much appreciate any plays and or re-posts & shares that you give my 'babies' ;)

Peace, love and freedom
