That is Physics 101. Even in Earth's low orbit, a spacecraft and everything in it, including a baby in a pregnant astronaut, will still be under the influence of the Earth's gravitational field of a strength of only slightly less than the 1G on Earth's surface, all while they're in weightlessness.

A key word here is "weightlessness". What does Physics 101 tell you about the gravity when you are weightless? Your mass doesn't change and weight is zero. So...

Also what does that have anything to with potential gravitational situation in a woman's womb on earth, which is what we have been arguing?

Floating in a water environment, weight is also zero due to the buoyancy effect as opposed to the free fall effect in orbit.



I didn't argue about the potential gravitational field effect to begin with, only the potential effect of weightlessness. You can check all my previous post. My last post about it was in response to your post talking about how a tiny object experiences the same G as a much bigger object.

All my discussion was about the potential effect of weightlessness, and the similarity of the effect floating in a liquid environment and in free fall in Earth's orbit.

You need a gigantic 10-15 ft deep pool to simulate near orbit gravitational conditions. NASA actually has facilities like this to simulate space conditions. A woman's womb is nowhere close to that kind of condition. A female Hulk might be able to do that but not normal sized human being...

Like I have said many times, you won't have enough liquid in the womb to have any effect on G.

End of discussion for me. Have a good day.

I don't think anyone on earth, NASA or whoever else, is trying to, or for that matter will be able to simulate "near orbit gravitational conditions".

At a depth of 15 ft of a pool of water, the Earth's gravitational pull is only infinitely smaller than that at the pool surface. As an example, even at the depth of the deepest part of the Indian Ocean, the gravitational pull is going to be reduced by less than 1/100th of that at the ocean surface, i.e effectively almost the same G.

Then why did you insist an embryo in the womb would experience different gravity than the mother?

Quickie said:

I suppose the liquid environment in the womb has much, but not 100%, similarity to a micro gravity environment.

I think the problem really starts when the baby is born into a space environment. We know that bone strengthening works in direct relation to the stress created on the bone structure working against gravity but how would the baby's bone structure develop and grow in zero gravity?

I never did.

Show me the post that I've posted that I even entertained such a crazy idea.

Aughhh, you still feel the pull of gravity even in water with neutral buoyancy. Go scuba diving and you'll see what I mean.
