Is Gravity the math formula, Fg=Gm1m2d2? Most likely, and yet, to a lot of people don’t know that unless they Ecosia it; like I had to do. I want to describe gravity in simpler terms, which might raise the current models for the formulas. I’ll try to be as short as I can.
First, and briefly, I’ll explain the birth of gravity. After a sun explodes, the energy and dust remaining floats free until the smallest particles attract each other through their own magnetic field. Some attract and some are either neutral or repelled. The most matter that collects, the larger the object becomes. All elements can be found in the dust and over time, they become large enough for us to see them as celestial bodies. These bodies can rank from plain rocks, to varying sized meteors, to planetoids, planets, gas giants and even the main event itself, a star. Some gas nebulas are primarily sun incubators.
So, what is gravity? Gravity starts as attracting particles that become something larger. It doesn’t simply end there. The collected particles of metals and gasses form into said rocks which attract other material and magnetically charged rocks. These form into larger asteroids, meteors and so on until the collection becomes heavy enough to stop floating through the developing solar system; pulled in many directions as other planetoids form. With enough material weight, the middle of the object becomes crushed. This happens as the object’s magnetized collection gains too much surrounding matter, and the most inner area heats up due to pressure. The massive amount of rock breaks down, allowing the iron inside to form and melt under the intense pressure.
The still collecting object will crash into other forming objects of varying girth, adding to itself. Even if the object breaks open and new material becomes entwined with the iron center, it only gets larger with more magnetic power. Hurdling through space, incapable of leaving the grip of the sun, this object has the potential to travel to the edge and back, or bump around the sun’s immediate gravitational zone. When the growing object gets too large, with a high enough speed, coupled with being too large to move from medium impact, it will stabilize into what we call an orbit.
Through impacts, and orbital path, the mass will spin. This spin tends to be fast as the collapsed center of iron and rock heat up many thousands of degrees. This melts all surrounding rocky matter turning it into molten slag. This covers the melted magnetically charged iron sphere, and in turn gains more iron and other metals. This is how a core is born. A collection of iron and other metals, rock, heavy impacts, rotation, and possibly orbit.
Gravity, by-in-large, is magnetism. Everything a planet is made of comes from the death of a star. All material added to this planet is merely part of the same material used to form it, and all that is used, becomes part of it. Gravity is the iron magnetic core what reaches far and pulls inward. The earth’s gravitational pull and atmosphere, reaches beyond our ever-so-slowly escaping moon. Meteorites, comets, asteroids, even another planet has been pulled towards the center of earth, as well as every other celestial body in the universe.
The higher the gravity; does not mean the larger the planet. When material run out, the planet stops growing. Earth has a gravitational pull of “1”. This simply equates to what we evolved into. The moon has far less gravity, thus we jump higher. If the earth was twice its’ size when we evolved, we would look different, and jump just as high, while jumping twice as high on the moon; if… the moon was as it is today in the supposed times-two earth scenario.
It is all about perspective. Nothing falls to earth. Everything is being pulled towards the center of earth. Nothing falls onto a dark star. The dark star pulls matter and material towards it. Gravity is magnetism, and it collects anything that comes close enough to it. While the core of the earth super heats the majority of the inside of the planet, the surface stays cool. Without the every-pulling super-heated core of planet earth, there would be no continents as land would be too hard to move. The best examples are moons, and planetoids like Pluto. Their surface is solid, marred only by heavy impacts.
I want to thank you for reading and I hope this helps people understand gravity, and where it comes from. Seeing how planets form, it may compel you to think about the gas giants. What is really beneath those heavy clouds, and more importantly, magnets on your keychain: Do they pull at you? You happen to go to them quite often. Thanks, and take care.
