Since our gravity is also one big mystery, to me at least; let me try and unravel what it is and how it may be connected to our own way of life. There are different elements known in the universe with different hardness in property.
These elements, when interacted with electricity, in any form it may be, may conduct electricity and some may not conduct electricity. For those that can conduct electricity also produces magnetism and the strength of the magnetic force is determined by the density of the conductible element. For example, stainless steel when connected to an electric current, will conduct electricity. Also, carbon steel when connected to an electric current will also produce electricity. Stainless steel and carbon steel have different hardness properties. Now, I’m proposing that the strength of magnetism between stainless steel and carbon steel differs, in which the attraction of magnetic force in a carbon steel is stronger than the attraction of magnetic force in a stainless steel.
Now, we might think that a piece of wood is not magnetic. We might think that it is just falling to the ground because of gravity. This is where it gets a little weird. The piece of wood we think is not magnetic is in fact, magnetic. The strength of the magnetic force is too small for us to detect. It also conducts electricity but in very small quantities that we fail to detect even with our gadgets, like electricity sensors, which in turn fail to start because of the strength of conductibility.
When a particle like a piece of wood, is interacting with another wood, or something else, we fail to detect the force of magnetism because the piece of wood, which used to be alive, is now dead and preserved. Because of density of the whole piece of wood, we will never sense the force of magnetism, but it is there. We’ve just never really cared or considered about it, because of the current situation which puts our attention to a more urgent matter, the stomach.
Now, since the earths core is made up of hard core iron or something like that, it is very big and very magnetic. Earth is also a very big place. With a lot of matter, interacting with each other, magnetically, but we never sense it that way. Because we think that the forces that we see are the result of our own doing, which in fact, it is the essence of the earth itself.
Different elements, with different hardness tend to act differently. We all know how water reacts when it is met with a mountain side, it goes down. If you try the same thing with a piece of 2 x 4, it will fall on it’s side because it is longer, and the more magnetism interacts with the earth, it will act, hence the result, the knock down of the 2 x 4 on it’s side. The strength of the gravity is constantly the same, but it should react differently, if there was a big magnet such as another planet like Jupiter, in space that was passing by us besides the moon. Then the earth will react in movement succumbing to a stronger force. Thus, any matter which is not magnetic to our standards is weak, and will always succumb to a stronger magnetic force.
This is why an exact same volume, distance, size of any matter differs; ie) same dimensions of lead and silicone will weigh different, because of variation of stregnth of magnetism.
To conclude, every matter in the universe is magnetic, and can conduct electricity but to a certain extent. Hence, the reality is, we fail to detect them most of the time.

This gravity is magnetism at a large scale. It has three distinct characteristics. First, everyone knows the "Attraction and Repelling" properties of the magnets. Second) For non magnetic objects, weight is noticeable. Two different elements will weigh different despite having exact same dimension. Third, the attraction at a microscopic scale, the attraction between cells in living things and atoms in non living things. As we all know, we're consist of cells that are capable of multiplying. These, despite that they're two different cells, are connected to each other by this same force.

When you consider these, this magnetic force is controlling the aging process, and the size of the physical living thing.

I'm saying that the holes in the newtons law and einsteins law will be patched using this theory. I don't want no scientists to be limping so I'm revealing the secret that Inuit knew all along. All we need to figure out now, is how to quicken the elements with Magnetism, and I bet only God knows how just yet.
