Humans need Earth-like ecosystem for deep-space living

Sending humans into space at this point is purely vanity.<p>This is exactly what we should build AGI to do - explore places humans can’t.

The point around gravity is weak. We have exactly two datapoints for long-term human habitation: 0G and 1G. There is a <i>vast</i> spectrum between the two, the effects of which we simply do not know one way or the other; pretty presumptuous to assert any particular shape of that graph without even so much as a third data point. Can we get away with 0.5G? Can we get away with alternating periods of 0G and 1G? Lots of entirely-unanswered questions there. Hopefully, with new manned lunar missions on the horizon, we&#x27;ll be able to collect more data on that front.<p>In any case, both centrifugal gravity and oxygen production are readily-solvable problems. We don&#x27;t strictly <i>need</i> the artificial ecosystems in question to fully encompass what&#x27;s on Earth to be suitable for long-term habitation; they just need to be sufficiently reliable.

&quot;Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.&quot;

The number of artificial biospheres that have every successfully supported human life is zero.

Who knows, our Earth could be one of those.<p>It would certainly explain things, like why we seem to be out nowhere.. I mean there is no signs of life, against all the odds. Deep mission alright.<p>It would explain why we started agriculture, civilisation etc so suddenly. It would also explain many of the myths, such as the ones about star people visiting us.<p>I would obviously create and seed a planet first, then monitor its development upto a point before going in to live onsite. Maybe we had created some folks there to do some gardening. When you arrive and they&#x27;re treating you like a king and after you left eventually the stories started to seem like fairytales.<p>It would fit with the idea that there was an ancient advanced ciliation, who was wiped out about 12,000 years ago, because of something like flood, solar events or asteroids caused floods etc. or they decided to reboot the experiment. But few who survived were able to restart civilisation at some basic level at least.<p>Since our ancestors were wiped out there has been this state of amnesia, like Graham Hancock puts it. We have been left wondering in the dark, asking ourselves who we are, why are we here and if there is anybody out there.<p>Maybe &quot;the gods&quot; will return some day and offer us way back home, but we will probably try to shoot them. All thanks to Hollywood brainwashing the world to imagine that aliens are some space insects who want to turn us into batteries. Why not imagine it would be more like the final episode of Battlestar Galactica or the world of Expanse? But who knows, maybe they&#x27;re already here and some suspicious folks are freaking out.<p>Anyways, sorry about that. Just felt that this train of thought was supposed to be spilled out here. &lt;InsetAllTheDisclaimersRequiredHere &#x2F;&gt;

Otherwise we&#x27;d be like fish out of water.
