My soon to be published new novel, He might be still on Mars, is set in 2586. There’s nothing magical about that year, just that it’s about 600 year in the future. probably the same time period in The Expanse, the excellent TV series now on Amazon Prime. I looked at a number of films produced in the last 100 years which tried to look at the future. This little number is about as comical as it gets. https://www.youtube.com/watch?v=U9eAiy0IGBI
Not so much for the dated reportage but the clothing, which is just a take on clothing in the 1930s, imagined as in 2000. Men’s clothing looks like a refugee from Fritz Lang’s Metropolis or a Devo costume. The bloke has a phone, but nothing like contemporary cell phones, and a belt with containers looking like they used empty Spam tins.
One of my reviewers was skeptical we’d still have some form of cell phone device that far in the future, but The Expanse, called the hand terminal. Its still primarily a communication device and function like a cell phone but a cell phone on steroids.
I wanted spaceship voyage times to be hours and days not weeks month and years. Even at the speed of light it takes nearly six hours to get to Pluto. In the book, light speed has been achieved but it requires a great deal of science and engineering to reach light speed without becoming infinitely massive. Most vessels operate ay 0.1-0.5 light speed, which are still challenging speeds to achieve. Voyages beyond the Solar System, to places like the Oort Cloud, take a year, and passengers are put into a stasis coma for a year while androids or Synths run the ship.
The story at heart is a manhunt which has diversions to Africa, and is concluded in the Russian Taiga, the coniferous forest of high northern latitudes. While researching this for the book I came across the Russian town Oymyakon, which is close to the northern Pole of Cold. You can check out the climate here, https://en.wikipedia.org/wiki/Oymyakon, which can be warm in summer, but deadly cold in Winter. Its a testament to Human adaptability, as much as living in hot desert climate or on remote atolls in the Pacific.
