Ahh, Zachary Vorhies. I remember your bizarre internal posts literally claiming that Obama's birth certificate was fake. I wasn't surprised at all when you leaked a pile of confidential information to a far right conspiracy theorist group (Project Veritas), and were subsequently fired.

I wouldn't trust a single word that comes out of this guy's mouth.

Getting a little off topic here, but general relativity is based on there being no observable difference between inertial motion and free-fall within a gravitational field. The weightlessness from free-fall isn’t just apparent. It’s identical in every way to the weightlessness experienced if you were sitting in one of the universe’s vast voids.

It is of limited meaning to say the gravity in LEO is 0.89G. That’s an Earth-centric statement, and ignores the gravitational contribution of the sun, the galaxy, the local group, and so on.... At best, you can say “a body initially at rest relative to the Earth at altitude 300km experiences an acceleration of 0.89g towards Earth”. Earth itself is in free fall around the Solar System’s barycenter, which in turn is in free-fall around the galaxy’s center of mass, which in turn is in free-fall around etc... etc...

The only gravitational experiment that could be done on the ISS to determine they were orbiting Earth (vs sitting in empty space far from any other bodies) would be to measure gravitational tidal forces.

When you create a drop of water and let it free-fall, it forms a sphere precisely because, from its frame of reference, there is zero gravity.
