Show Notes & Research
From the Show
Broadcast: 30th August, 2015
Last update: 2nd September, 2015
- Read the feedback, notes from the last show
- Begin recording
- Introduction and description of the podcast, goals, modus operandi.
- What An investigation of everything from a British perspective by two brothers (who consider themselves to be relatively normal chaps), one topic at a time.
- Who Geoffrey Campos (engineer and devil’s advocate),
Benjamin de-Campos (designer and believer).
- How Choose a topic of interest, spend a little time researching it, have a discussion then publish the notes.
- Why The main benefits are the fostering of a greater understanding of the world before we die and hopefully, to prompt further thought and discussion from our listeners.
- The topic we will be nibbling on in this oddcast is Extraterrestrial Life
From the most corpulent blue whale down to the tiniest viral particle—everything that has ever lived has done so on our very own tectonically plated, watery shrouded, iron cored four billion year old mote of dust. Or maybe not. Perhaps, despite the disappointing lack of findings from the SETI programme, there is a single planet or moon orbiting one of the 200 billion or so stars in the galaxy harbouring what we would recognise as life. Are we alone? Would we ever detect alien life given the distances involved? What are the odds?
What we’re not talking about
- Peter Stringfellow
- Planned obsolescence
Each bullet is a talking point. Sub-bullets are topics that may or may not be covered. Usage: Read the bullet and sub-bullets then talk about some or all sub-bullets.
- According to Booble: life is the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death. It’s so profoundly annoying that there isn’t even a ‘paste and match style’ option in this god forsaken whatever it is.
- Tardigrades - can withstand vacuum, super high temperatures. Typically 8 legged, over 1,000 species. Can get up to 1mm in length.
- Extremophiles e.g. Archaea
- The God damned vastness of the universe
- I simply cannot comprehend it
- Milky Way 100,000–120,000 light-years across
- Andromeda Nearest (Proper) galaxy to Milky Way, 2.5 million light-years from Earth - largest of our local group (population of 55 galaxies)
- Nearest group is M94, 13 million light years
- Our local cluster is Virgo, 110 million light years across and contains at least 100 galactic groups - including ours
- SETI - Search for Extraterrestrial Intelligence
- 19th century first searches were conducted
- Interested in extraterrestrial intelligence, not life per se. Not sure I understand the difference.
- UFO sightings and anecdotes
- I want to believe
- desire for there to be life on other planets
- 2013 Puerto Rico UFO, one of the better sighting videos
- Weird stories about our origins
- we’re originally from Mars for example
- Panspermia theory Intelligent seeders
- von Neumann probe - self replicating machine
- What does Ken Ham think about all of this?
- He says: ‘we should stop exploring space because the bible says aliens would go to hell’
- Confirmation bias
- ALH84001 Meteorite found in Allan Hills, Antarctica in 1984, fossils of Martian bacteria on carbon structures
- Comet 67P The Philae lander/robot, complex organics on a dust covered water ice ball.
- Drake Equation 1959 Astronomer Frank Drake used a 25m dish in Virginia to search for intelligent signals. Failure.
- It’s non-conceivable that there isn’t life elsewhere in the universe. If you doubt that proposition, you simply aren’t grasping the sheer scale of the universe. Scientists probably think the universe is ten infinities wide (in miles). Maybe twenty.
- Rare earth hypothesis vs. Mediocrity principle
- Planetarium or zoo hypothesis
- Fermi paradox Physicist Enrico Fermi, ‘1950 Where is everyone?’
- Gaia theory
- Arecibo message Broadcasting our existence
- Super predators
- Would we recognise alien life?
- Linear A is an ancient written language from Greece that has yet to be deciphered
- 2001: A Space Odyssey, 1968 Stanley Kubrick
- Close Encounters of the Third Kind, 1978 Steven Spielberg
- Independence Day, 1996 Roland Emmerich
- Dark Star, 1974 John Carpenter
Terminology specific to the topic
- Fermi Paradox
- String Theory
- Details about site, contacts, next show: femininism
- Outro music choice - something open source or out of copyright so we don’t get sued
- Wow! signal recorded in 1977 by Jerry Ehman on SETI’s ‘Big Ear’ radio telescope which was pointed at the Sagittarius constellation near the centre of our galaxy.
- Recording ends, postmortem recording begins
- Add intro music, outro, any editing
