I believe you understand the reason why David Scott dropped hammer and feather, not 15 kg dumbell and .15 kg baseball. 1 part in 10^25 is a ridiculous claim. Variance that small you can not say it is the result of gravity, magnetic field, temperature, humility, spiral momentum of the...

Can you explain: - How abut the surface and shape? - Didn't David Scott's hammer fell in sync with feather, the mass, size, shape, and surface are clearly very different? - The different size, and weight, of the balls fall in uniform acceleration in all experiments I have learned, when the...

Correction, magnetic slime. David Scott's hammer feather drop, along with all other falling body experiments, shows: The gravitational acceleration of an object is independent of it's shape, size, and surface; in addition to it's own mass, isn't it?

Do you mean performing the same experiment on different moon (a), or dropping a moon along with the hammer and the feather on our Moon (b)? (a) I believe the difference is the atmosphere and the strength of it's gravity field of other moon. If there was no atmosphere, the hammer and the feather...

First of all, I appreciate and enjoy this discussion very much. Thank you! (a) Indeed, the experiments showed nothing new as many historical experiments. However, I believe the universe does not lie to us, but interpretations could vary from time to time and person to person. (b) You said the...

Doesn't the hammer and feather drop performed by David Scott in Apollo 15 show the independent of mass and gravitational acceleration?

Free fall and inclined plane experiments since Galileo show the uniform acceleration of falling bodies regardless of their compositions, shapes, sizes, and distances. The important fact that has been overlooked is, gravitational acceleration is independent of composition, shape, size, and...
