Why Worldbuilding Stack Exchange recommends it

Worldbuilding Stack Exchange answerers point people to it when a question is about how humans might develop, evolve or live if born in low-gravity or zero-g environments.

Recommended by 2 people across 2 different months, 2014 to 2017.

What it is

A Vsauce explainer by Michael Stevens on what would happen to a person conceived or born in space, covering weightlessness, how zero-g affects bodies, and what is known about spaceflight and biology. The description lists NASA and Wikipedia sources on orbits, zero-g effects and the question of babies born in space.

There is some speculation on this, and our friends at NASA have some things to say. Specifically Patty Currier, from 1999, [LINK] talks about babies in space, and Michael from Vsauce [this video] talks pretty well about low-g or zero-g living in space, and finally NASA's article " Gravity Hurts (So Good) [LINK] " are good initial sources for this. Here some of the effects of gravity the body: The head will be thicker, because more fluid pressure gets to the head, because there is no gravity to pull the fluid out of the head (and into the feet). So babies will develop thicker skulls. Legs will be underdeveloped, because they don't experience the stress of holding a body up. Hands will likely be ju

This video explains what would happen to the people born in space: [this video] It shows that with out artificial gravity a colony on space stations aren't really viable.

For mammals, things like height are mostly controlled by DNA. So the difference wouldn't be huge. But there would be a few differences. Size Astronauts grow about two inches during their time in space. This is because the effects of gravity compress your spine on Earth. When gravity is no longer affecting you, your spine expands again (the spine expands because it absorbs moisture from your blood). This would also happen on Mars, because gravity is less strong. So people would probably be half an inch to an inch taller on mars.[1] Lighter gravity means less force on us pushing us down. That means our bones would likely get smaller. If our bones didn't get smaller, then we would more easily b

[this video] Maybe to throw in something from vsauce. Have seen this video some time ago, don't know how relevant/helpful this is. I can't remember much from it, just searched it really quick at work..
