Current Events > can babies being conceived and raised in low/0 G environment live?

(+) Yeah! (+)

we are speaking of trying to colonize other planets but if it turns out fetus needs earth gravity then hope for human being able to take off to the stars died instantly.

also there's really no moral way to test if babies would be born healthy in 0 G environment.

this is what i found on mice tests:

In the STS-80 space shuttle mission, mouse 2-cell embryos were collected on the ground, launched into space and cultured for four days in G. The control embryos on Earth developed to normal blastocysts, but in the space flight group, none of the embryos showed any sign of development, and all degenerated (Schenker & Forkheim, 1998) . A more reliable experiment was done on the Cosmos 1129 mission in 1979, when mature male and female rats were sent into orbit and then allowed to intermingle in a common breeding chamber (Serova & Denisova, 1982). However, none of the females gave birth, although postflight examinations revealed that ovulation had occurred. Two of the females were reported to have achieved pregnancy, but the embryos appear to have been resorbed.

but humans can't reabsorb fetus like other mammals can.

If you nut in a spaceship going lightspeed can that nut pierce the ship?

---

It's unlikely, and unethical to attempt any particularly relevant tests.

---

so humans will die with our planet's death that we accelerated ourselves. pretty nice comeuppance

How could it if the nut only floats around and doesnt go anywhere

they be floating into eggos

Just have to settle somewhere with decent enough gravity, or build stations and spin them for gravity.

In wherlchairs maybe. Being in zero g for extended time reduces bone density.

That's why we should really be looking into generating artificial gravity via centrifugal force for orbiting space stations. Or even for deep space human transport. You could also generate artificial gravity via sheer acceleration too, which would be useful for deep space rocket ships.

to do that in such a way that you're not going to sheer the ship apart or make everyone viciously ill because of the difference in force between your head and your feet, you'll have to make the ships absolutely gigantic. we'll need an infrastructure system in space to build these giant ships, and that's well over 100 years away.

Good thing mars doesn't have 0g

Raised, no. Without gravity development is fucked.

Yeah, but it only has ~38% as much gravity, which will mess with things. Probably a lot, but I don't know really know.

There're probably answers to be had, we're just not investing much in finding them out, let alone in even more pressing problems.

Space colonies and even spaceships or stations can simulate gravity using gravity blocks or other forms for artificial rotation

You mean centrifugal? Admittedly I don't know too much about it, but NASA and JAXA planned to have a centrifuge module to the ISS to experiment with biological organisms less than a meter tall to gravity levels between iirc 0,01 and 2 G. So I'm not really entirely sure how true that is.

Centrifugal force does not exist

Without lightspeed travel, we're only getting to local planets and anywhere else via cryostasis anyway, so it's not a particular concern. It's not like we'd build permanent space colonies with no gravity.
