Is the orbit really around the object? Or around the central point of gravity for that object?
If the earth’s surface didn’t revolve around its axis, would geostationary orbit be possible as used in this reality?

“freefall along the curvature of Earth ”. It’s just free falling at a rate that keeps it above a certain point on the surface of the earth. And in reality, the geostationary satellite is moving at a greater velocity in relationship to the earth’s axis that the certain point on earth’s surface. The satellite is completing a circle with a greater radius for the same amount of time. Is that false.
That is not false, just completely irrelevant since it doesnt change the fact that it doesnt move relative to the direction of gravity, and therefore cannot orbit.
You didn’t answer to:
Due to the fact that the force of gravity is downward, it would only seem logical to define downward as a positive direction in gravity equations. This is essentially inverting the Cartesian coordinate system. Using vectors is an effective way to describe the initial and resulting motion of the objects and to set a convention for direction.

Orbital stability
Edit
A geostationary orbit can be achieved only at an altitude very close to 35,786 km (22,236 mi) and directly above the equator. This equates to an orbital velocity of 3.07 km/s (1.91 mi/s) and an orbital period of 1,436 minutes, which equates to almost exactly one sidereal day (23.934461223 hours). This ensures that the satellite will match the Earth's rotational period and has a stationary footprint on the ground. All geostationary satellites have to be located on this ring.

Because it wasnt relevant either. Did you read what I posted?

Please cite or quote where gravity has a direction.
So, a satellite in geostationary orbit has to travel around the earth at 1.91 mile/sec to maintain its orbit.

The direction is straight down. Since the Earth is curved this direction changes.

A geostationary satellite doesnt travel around the Earth. It's over.

Lol, so typical.
"Am I right guys...!"
Why dont you say something to save your debunked geostationary orbit debacle?

Give it up. You cant explain geostationary orbit. It's not an orbit. An orbit requires falling around the object. Geostationary orbit debunked.
Unless anyone else has an actual counterargument? Yeah thought so.
Techopedia explains Geostationary Orbit
A satellite in geostationary orbit remains exactly above the equator, so it does not change its position with respect to a location on Earth. A geostationary orbit is a path given to high Earth orbiting satellites to monitor weather and for observational and telecommunication purposes. High Earth orbits are orbits that are around 22,236 miles (35,786 kilometers) directly above Earth's equator. This position is ideal since Earth’s gravitational pull is exactly such that the speed of the satellite is kept equal to the orbit velocity of the Earth.

And you didn’t answer to: You do understand a geostationary satellite is still completing a circle about the earth’s axis ever 24 hours? (23 hours and 56 minutes to be more specific)
It may orbit a point in space but this is irrelevant.
