I'll make one more attempt freshstart. I am referring to gravitational field (little g) NOT to gravitational constant (big G). I'll use a visual to make my point.
Here is the video of the hammer and feather dropped on the moon. Hammer vs Feather - Physics on the Moon - YouTube
Notice the RATE at which both fall. Now look at the RATE that which both fall in the OP's video clip. Slower on the moon right? Whys that? BECAUSE THERE IS LESS GRAVITY THERE. And WHY is there less gravity? BECAUSE THE MOON HAS LESS MASS than the earth. This is the effect of gravitational field! Little g. This is what I'm talking about, little g, NOT big G.
The gravitational force between two objects is directly proportional to the product
of their masses, and the greater the force the greater the acceleration.
Here is your thought experiment. You take two different spaceships and go to two equally remote parts of the universe. That is, places equally remote from all gravitational influences. You have two bowling balls in one spot and two feathers in the other. You place the two bowling balls exactly 1 inch from each other and stabilize both, so they are perfectly still. You do exactly the same thing with the two feathers in the other equally remote part of the universe and at exactly the same time. Which pair of objects will bump into its twin first? The two bowling balls or the two feathers? (here's a hint, think little g).
AGAIN, from the initial example, the difference in time between bowling ball and a feather hitting the earth in a vacuum (or in the moons vacuum) is EXTREMLY tiny, but if you understand the principle
involved you understand that the bowling ball wins the race, even if its only by the width of an atom, simply because it has more mass.
I can't make it any simpler, and with that I give up (unless you can cite the reference for that magic number that mass needs to attain before it begins to produce gravity. I would be very interested in knowing that.
