Gravity still can't be measured so Gravity has never verified.
Why do you keep telling lies even though you have been told the truth so many times?
The term
Gravity means the local gravitational field, and varies a little with location and altitude (up to 0.5%) and it is comapritively easy to measure.
So your claim that
"Gravity still can't be measured so Gravity has never verified" is totally incorrect and ridiculous.
All you need is a Gravimeter as in
Gravimeter
A gravimeter is an instrument used in gravimetry for measuring the local gravitational field of the Earth. A gravimeter is a type of accelerometer, specialized for measuring the constant downward acceleration of gravity, which varies by about 0.5% over the surface of the Earth. Though the essential principle of design is the same as in other accelerometers, gravimeters are typically designed to be much more sensitive in order to measure very tiny fractional changes within the Earth's gravity of 1 g, caused by nearby geologic structures or the shape of the Earth and by temporal tidal variations. This sensitivity means that gravimeters are susceptible to extraneous vibrations including noise that tend to cause oscillatory accelerations. In practice this is counteracted by integral vibration isolation and signal processing. The constraints on temporal resolution are usually less for gravimeters, so that resolution can be increased by processing the output with a longer time constant. Gravimeters display their measurements in units of gals (cm/s2), instead of more common units of acceleration.
Gravimeters are used for petroleum and mineral prospecting, seismology, geodesy, geophysical surveys and other geophysical research, and for metrology. | |

But when you, so ignorantly, claim that "Gravity still can't be measured so Gravity has never verified."
You are really claiming the the
Universal Gravitational Constant,
G still can't be measured.
This claim of yours is not only wrong, but deceptive and
totally dishonest as you have been informed numerous times that such measurements have been performed numerous times.
Accurate measurements are still not easy, but here are some reports of modern experiments in the lab:
Scientific American, Puzzling Measurement of "Big G" Gravitational Constant Ignites Debate [Slide Show]Phys.org, New measure of gravitational constant higher than expectedNature, Precision measurement of the Newtonian gravitational constant using cold atoms - and not always will heavy lead balls!
Phys.org, Why do measurements of the gravitational constant vary so much?And before you go into raptures over the "the gravitational constant varying so much", look at the variation observed:
A set of 13 measurements of G exhibit a 5.9-year periodic oscillation (solid curve) that closely matches the 5.9-year oscillation in LOD
measurements (dashed curve). The two outliers are a 2014 quantum measurement and a 1996 measurement known to suffer from drift.
The green dot is an estimate of the mean value of G after the 5.9-year periodicity is removed.

Can you show us
any Flat Earth experiments with accuracy approaching that?
Yes, there is plenty of experimental verification that masses, even single atoms, are attracted to other masses.
And here are the results all the "Cavendish type" measurements up to the year 2000:
Results of gravitational constant measurements till 2000.Here is a simple demonstration that a force is produced, though no attempt is made to actually measure
G, the
Universal Gravitational Constant.There is this article with an explanation of the effect gravitation with
a very simple set-up to demonstrate it:

G with this crude experiment, just to demonstrate that there is a force.
So don't claim anymore that
"Gravity still can't be measured so Gravity has never verified."Gravitation has been verified and measured numerous times and you are being totally dishonest if you claim otherwise!
