Time travel technique
Buying The almanac. Varieties of time travel: mutable, immutable, and branching. The way BTTF mixes these options at its leisure. The butterfly effect. Coping with the scale of possibilities. Strategic infanticide and Godwin’s Law.
Taking into account frames of reference. Appearing suddenly in near-vacuum if you don’t properly calibrate your time machine to also account for space travel. The importance of accurate time measurement e.g. Doctor Who The Movie. Destroying “the universe” but only the local area as causality here could not affect far away galaxies due to expansion. ¯\_(ツ)_/¯
Bricking your self-lacing shoes. Keeping your shoes from joining a botnet. Self-smoking shirts. The periodic nature of futurism where “the future” always looks basically like now but with neato accessories. Hoverboard hoaxes and disappointments.
A hundred years to uninhabitability is a little bit quicker than we thought. Timelines here to red dwarf and all the unpleasantness in between.

Planetary travel in deep space
Relativistic impact vulnerability. Appreciating Earth’s protected position within the heliosphere, blocked from impactors by two gas giants and its own moon.
Earth’s new home
Traveling across deep space with no sun. If you dig deep enough, mayyyyyyybe Kelvin’s “secular cooling” would keep everybody warm for the trip. Signing up for some eye shine. The three-body problem.
Living underground. Shielding from the radiation and frigid cold of deep space with kilometers and kilometers of Earth. Learning to eat lots of algae, crickets, and fungus. Taking advantage of geothermal energy at depth. Dealing with Earthquakes while being under some of them. The safety of tunnels.
Smuggling pickles in your pants into space. And maybe some vodka or cognac. “Who wants a warm pickle?”

Universal translators. A visit from Nick Farmer from the past, when we asked him about universal translators in our Q&A #2.
Space is big
Mind-bogglingly big! The bigness of space and the difficulty in finding a sense of scale from a human perspective.
Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.
Doors deriving sexual pleasure from providing their service. Polar opposite extreme AI demeanors. Deep Thought and AI constraints.
