This was the best worst thing we’ve ever seen. I’m sorry. You’re welcome?

Leaving whole rocket stages to just kinda be in orbit and hit stuff. Talking in space by providing your own atmosphere thanks to your incredible, super lung capacity. Also, how that doesn’t work and Superman needs to be a close talker and hold conversations by vibrating his mouth directly on someone else’s spacesuit helmet.

The hair that can hold at least a half ton. How does Superman cut his hair? Introducing weird gnarly alternate Superman with really long hair and uncut fingernails. Donating Superman’s bits to materials science. Making things out of hair. Totally realistic space elevator musings. Superman as a launch platform. Dissecting the Man of Steel for fun and profit. Using Superman for “free energy” (Saturday Morning Breakfast Cereal).

Superman’s built-in orbital mechanics skills. The tiny bit of nothing that would be all of 1987’s nuclear world arsenal against the power of the sun. The relative tiny-ness of the only nuclear weapons ever used in war. Proposals for nuclear de-proliferation. Going Dr Manhattan on the problem.

A bunch of stuff oh god this movie was silly

Nuclear Man’s totally fab nails. The golden crotch-trim on his super suit. Plugging a volcano. Superman’s “brick vision.” Slowing things down, because the moon has “less gravity.” It’s obvious, really. The actual disasters that await us if Superman pushed the Moon away.

A hundred years to uninhabitability is a little bit quicker than we thought. Timelines here to red dwarf and all the unpleasantness in between.

The surprising difficulty of actually reaching the sun. The Parker Solar Probe. Taking a close peek at the corona and the young solar wind. Close as in millions of miles.

Shifting circumstellar habitability zones. Moving the planet out nearer Jupiter as our sun expands. Throwing moderation to the wind and ditching the solar system. Tidal forces.

Relativistic impact vulnerability. Appreciating Earth’s protected position within the heliosphere, blocked from impactors by two gas giants and its own moon.

You folks asked us a bunch of questions. And we gave a bunch of answers!

I’ll leave the actual Questions and Answers to be listened to in the episode, but we did mention some resources etc which I’ll link below…

To whet your appetite if you’re as excited as us about the possibility of Decipher History:

“Just make stuff!” But then for technical details for other Linux podcasters, my dotfiles (application configurations) are shared openly on Github. Files and scripts relevant specifically to our podcasting are probably all mentioned here.

Creative Commons and free software and making the world better by helping more people make their stuff.

We like this show lots! Thus, our continuing coverage:

The oft-overlooked actual difficulties of space settlement. Not technology and logistics, but like, how hard it will likely be for the humans doing the job at first. And second. And then for a while after, too.

Growing fresh food in space habitats. Poop-potatoes. Wide-spectrum LEDs. Self-contained hydroponics/aeroponics.

People in spaaaaaaaaace. Dealing with microgravity. Bro, do you even lift in space? Eyeball un-squishing. Figuring out how to burp. Fluid-pooling and major injury.

Turning people into jelly. Differing human sensitivity to sustained g-forces in different directions. The wonderful engineering concept of the ship with omnidirectional seating that reconfigures on-the-fly for optimal g-resistance (The Razorback).

Turning into jelly and then having your jelly explode your ship, because physics. Relativistic baseballs. Long-haul space-racing and how to be your own butt-wiping pit crew.

Nuclear non-proliferation treaties in space. Orbital kinetic weapons and cloaked nuke-ships playing the role of the submarine as deterrent.

Minimum viable star system bootstrap answering machine. The Fermi paradox. The odds that most of the signs of alien civilization that we might discover would be past.

Ahhhhnold! Your average Joe, working construction just like any other regular guy who is a giant bodybuilding monster-person. We really missed this in our coverage of Total Recall 2012.

Memory “insertion” and memory “deletion” or “blocking” in mouse studies. The great distance from where we are now to trivial memory “vacations” a la Recall. Semantic memory, autobiographical memory, and muscle memory.

Ideal tracking-implantation locations. The incredible utility of the anus for tracker storage, weighed against the small time window.

Building Martian settlements with as much radiation exposure as possible: glass! glass everywhere! Radiation exposure on the Martian surface. Burying your dead on Mars: a tasteful resource-wasting mausoleum indoors, a giant pile of bleached-out mummies outside the door, or arrange them in awesome poses?

Natural resources in space. Calculating mining cost vs cost to get it where it will be useful. Mining and transporting Helium-3 for fusion energy. Harvesting oxygen from frozen water and getting rocket fuel as a bonus. NASA’s Moxie and inventing trees for spaaaaace. Making your Martian habitat smell like a dirty fish tank, for science.

Well, we don’t normally do this sorta thing, but oh man this was so good! What the film is about, how it is about, and why it was so special. Appreciating those who do the best work of making history relatable (cough Dan Carlin cough).

Film degradation. Scratching, exposure, shrinkage, physical tearing. The crapshoot that is video frame rates in early 20th century film footage. Crank cameras and gearing and compressed-air constant-framerate cameras. Correcting for all of this and the challenge of bringing it all up to a standard 24 fps.

The optical illusion that we perceive as movement on a screen. Persistence of vision. Video framerates and the “refresh rate” of the human eye. Motion interpolation as an offense against art and all things good. Tom Cruise fighting the good fight. Motion interpolation as a really neato technology which is actually really cool when not on by default on new televisions. Motion interpolation in VR or video games.

Historian types and objections to the “enhancements” introduced by the filmmakers. Art vs education and the importance of relatability. Modernizing history. Colorization. 3d-ification. Finding it hard to complain about digital enhancement and remastering which leaves the original materials untouched.

Compounding acceleration in the relative vacuum of space. Incredible efficiencies versus chemical rockets, and the very low force produced making it only appropriate once spaceborn. The differing problems solved by chemical rockets and ion drives. The benefit of ion drive once out of Earth’s gravity well and going far away. Earth’s tectonic plates, slowly building up to escape velocity. That beautiful blue glow. “Ionic wind” aircraft in-atmosphere: a completely silent aircraft motor with no moving parts!

Methods of landing on Mars: Aeroshells, parachutes, rockets, and balloons. Past examples. Different bodies in space and their particular atmospheric densities, atmospheric conditions, and gravitational acceleration.

Nuclear power vs solar cells. People’s presumption of full-on nuclear reactors rather than the smaller and less-efficient radioisotope thermoelectric generators like on Curiosity. Wondering why we don’t use tiny nuclear robots to blow the dust off of the solar robots. NASA, call us for more great ideas.

Martian dust storms. The low density and force of Martian dust storms, contrary to popular depictions. The visual impressiveness of huge Martian dust storms from space relative to actual effect. The (low) density of the Martian atmosphere and its make-up. How 60mph dust storms are are actually not that powerful: with low gravitational acceleration, static charge, it is very very easy it is to keep dust particles aloft.

The revelation that “geocentric” and “geostationary” apply very specifically to only Earth and there are other words particular to the other major bodies in our solar system. All of the other centricity classifications, including Arecentric for Mars as in the film (though they don’t use it).

Hypoxia and inability to give detailed instructions to your AI on how to disperse the spirit of humanity into the universe.

Giving’em the old Philip K Dick joint. Cyberpunk. Adaptation fidelity.

Luminescent tattoos! Bioluminescence, electroluminescence, phosphorescence, and maybe some other -escences too! A world with three boobs. Well, maybe more than that in the whole world. Hand phones. Ubiquitous smart glass. Neck-mounted face-replacing direct-eye laser projectors. Memory manipulation and deletion.

Digging a hole through the Earth. Trying to find hard things to do when building a space elevator is too easy. Adding unnecessary rockets to your earth-faller to reach a seventeen minute trip time. Digging deep in the Earth and heat issues. Finding impenetrable hot rock stew even without piercing the crust. Atmospheric pressure in the center of the Earth. Making it work by vacuum tube. The one easy straight line through the Earth that avoids the Coriolis effect, and the actually useful curved lines between land areas.

Camera rocket grenades that explode into camera bullets. Like a camera, but more messy. IR scanning. Two-dimensional room-mapping by Roomba. Photogrammetry. Playing VR hentai sex games in your room, in your room.

Glistening, rippling man-meat. Sweaty pecs. Aggressive handshakes with biceps the size of coconuts. Longing for the good old days. Feeling unjustified disappointment when our heroes aren’t giant walking meat monsters. The inapplicability of the bodybuilder physique to actually getting hero stuff done. Bodylifting.

“Savant syndrome is a condition in which someone with significant mental disabilities demonstrates certain abilities far in excess of average” -Wiki. As opposed to someone just simply being awesome at something. Josh’s recent related coverage from The X-Files Podcast @ LSG Media. Acquired savantism. Aptitude for… alien user interfaces? Trans-cranial magnetic stimulation.

Chess club vs computer club. Afterschool D&D. Duke Nukem and Team Fortress LAN parties at school.

Predator vs prey. Linguistically, should they be called “predator” if they hunt mainly for sport? “Predator” as a label for a biological relationship in which one creatures hunts and eats another for sustenance. The deadliest cat in the world. Humans as top “predator.” How to judge top predator when the line is not so clear cut.

Survey of movie alien contact scenarios and what they reveal about us. Energy required for interstellar travel and the likelihood anyone will happen by by accident. Government secrecy. Zip tie budgets and how to keep an alien captive. irl tranquilizer dart use and the inherent dangers. Why not to shoot yourself with an alien tranquilizer dose.

Selecting desirable traits from around the cosmos. Leave enough room for my stomach. Spinal juice collection. Gene manipulation. Selecting for intellectual traits: competitive science. Interpretive flex-dancing to enable armor modes.

Reasonable solutions to the predator problem. The fix for climate change (fusion?). Arnold Schwarzenegger. The Terminator integrated with The Predator, Aliens, and Blade Runner. How awesome was the original predator?
