Interstellar travel

Mon May 27, 2019 3:37 pm

Computing the minimal crew for a multi-generational space travel towards Proxima Centauri b
https://arxiv.org/abs/1806.03856
By allowing the crew to evolve under a list of adaptive social engineering principles (namely yearly evaluations of the vessel population, offspring restrictions and breeding constraints), we show in this paper that it is possible to create and maintain a healthy population virtually indefinitely.
Under the set of parameters described in this publication, we find that a minimum crew of 98 people is necessary ensure a 100% success rate for a 6300-year space travel towards the closest telluric exoplanet known so far.
Too bad these bugmen don't account for planned parenthood, hypergamy and monkey-branching. In a real world scenario they'd be lucky if any babies were born at all, unless the bugmen on the ship went full sharia on the females.

You're never going to get people to give up on choosing who they fuck. Especially after one generation. I also don't know who you get past the Westermarck effect without creating a whole ship full of degenerates.

Cryogenics is the better pursuit. Or just building space stations at progressively further and further distances until you get to where you want to be.

The problem with cryo is that radiation damage to the frozen bodies will slowly render them unviable over a few thousand years. But if you get your ship to go faster you have the problem of shielding from induced cosmic rays as incoming particles have higher relative mass striking your ship and photons get blue-shifted into nasty radiation. So more radiation damage to the bodies.

Ideally what you want to do is send an automated ship that has a store of frozen embryos, artificial womb technology, and robot nannies. You can heavily shield the embryos since they don't take up much space, plus you can ship thousands of genetically distinct people which will prevent inbreeding. Plus any kind of disaster will just be an expensive waste rather than a tragedy where lots of people die. Plus people are more likely to contribute to the project with the idea of "your progeny will colonize the galaxy" rather than "go die in an underground aluminum box on Proxima b".

Space colonization is impossible without genetic engineering, we are simply not adapted for it and you cannot rely on technology all the time to survive.

We could maybe send a machine to another planet that would go on to create human like creatures, also we need to have something to eat on the new planet.

Do you have a source for this? I'm interested and want to read more.

Check out the Science and Futurism with Issac Arthur channel on youtube. He does videos on space colonization and the fermi paradox.
