After a recent post discussing zero-g imagery (https://forum.tfes.org/index.php?topic=10232.0), conversations led to shielding from the direct force of UA.  More specifically, breaking free of the shielding might account for zero-gravity.

The Wiki doesn't seem to contain anything about this beyond the following:

The mass of the earth is thought to shield the objects atop it from the direct force of UA.

So my question is this, should the Wiki attempt to explain this theory OR does current FET have a different explanation for zero gravity / dispute it all together?

I guess that depends on what zero-g you refer to.  Do you mean the kind experienced in free fall, like inside an airplane flying a parabola or in a spacecraft in orbit?    The former is easily explained with gravity or UA, the later can only be explained with gravity.   

Shielded from UA would do what, hover, float, fall?  I am confused.

Hey TomInAustin - the other post might provide some further info.

I was talking about the kind of zero-gravity astronauts would experience whilst in orbit/space, as opposed to almost-zero-g in parabolic flight. 

JHelzer made the suggestion that zero-g might be explained by leaving the Earth's shielding from UA: "If a small mass, for example a rocket, escaped the UA shielding provided by the earth, would it not follow that the UA force would have direct effect and accelerate the mass along with the earth producing the effect we see in the OP video.  What I am suggesting is that what is called low earth orbit could instead be stepping outside the UA shielding above a flat earth."

I would argue that an object in orbit would prove UA incorrect.  Since orbit, as we know it goes around a spherical object UA would have to be accelerating in all directions at once.

Technically, they are the same thing.  Objects in orbit feel a sizable fraction (about 90% on the ISS) of their normal gravitational pull, but they are in a "perpetual parabolic arc", so to speak.  To be free from significant gravity, you would need to be a few light years away from any significant mass.

Thanks all for your contributions, but we seem to be going down a different path.  I suppose what I'm interested in is whether astronauts (such as in the video below) are experiencing zero - or almost zero - G because they are no longer being shielded by the Earth's mass, as per JHelzer's hypothesis.

In particular, I'd be interested in the consensus from FE'ers (because I expect RE'ers to share my view).

I think most FEers would say the video is fake what with NASA being fake and all.
