A more necessary conclusion might be the phenomena is mislabeled.
And since kinetic energy is a function of both mass & speed, the impact energy may be different in amount, but should scale evenly, and the "energy they fall with" should be likewise equal.
None of which addresses the actual challenges.
Get some background:
1. The Mainstream version of Gravity
The NASA website states:
"Because of gravity, if you drop something, it falls down, instead of up. Well, everybody knows that! But, what does this really mean? What is gravity?
Spiral galaxy Gravity has played a big part in making the universe the way it is. Gravity is what makes pieces of matter clump together into planets, moons, and stars. Gravity is what makes the planets orbit the stars--like Earth orbits our star, the Sun. Gravity is what makes the stars clump together in huge, swirling galaxies."
The Universe Today website states:
"Gravity is one the four fundamental forces of the universe and is considered a noncontact force. It is what holds the planets in orbit as well as the very universe itself. It is what keeps us from floating off into space and plays a crucial role in almost every nature process from the ocean tides to the body’s circulatory system. Gravity comes from mass. The more mass an object has, the more gravity it will exert on objects around it."
In 1687, the Occultist and Magus, Sir Isaac Newton, published Principia, which hypothesises gravitation, and included all the efforts of Copernicus, Brahe, Kepler and Galileo before him.
In 1797–98, The Cavendish experiment was performed by British scientist Henry Cavendish. He played with some led balls in his shed, and declared 'gravity' with some pretty
flaky formula.
By the late 1800's, others had found error in Newton's theory (most known is the errors with the movement of Mercury).
By 1915, Einstein believed he had fixed the errors in Newtons' work, with his Theory of Relativity. He theorised that gravity is what happens when space and time (the same thing) is curved or warped around a mass, such as a star or a planet. Thus, a star or planet would cause kind of a dip in space so that any other object that came too near would tend to fall into the dip. Einstein basically explained how gravity is more than just a force: it is a curvature in the space-time continuum. Einstein was pretty cool though, with quotes like, "Nothing will end war unless the people themselves refuse to go to war."
The Theory of Relativity is still taught today. It teaches that in our own Solar System, not only does the Sun exert gravity on all the planets, keeping them in their orbits, but each planet exerts a force of gravity on the Sun, as well as all the other planets, too, all to varying degrees based on the mass and distance between the bodies. And it goes beyond just our Solar System, as actually, every object that has mass in the Universe attracts every other object that has mass — again, all to varying degrees based on mass and distance.
But this theory of Gravity is not complete, the maths is super complex, and no man on earth truly understands it.
From Universe Today:
"
Gravity still remains one of the biggest mysteries of physics and the biggest obstacle to a universal theory that describes the functions of every interaction in the universe accurately.
If we could fully understand the mechanics behind it, new opportunities in aeronautics and other fields would appear."
