The Genesis of Gravity

Let’s start with the origins of gravity. When a star explodes, the energy and remnants disperse into space until tiny particles begin to attract each other due to their inherent magnetic fields. Some of these particles come together, while others remain neutral or are pushed apart. The more matter that coalesces, the larger the resulting object becomes. This cosmic dust contains various elements that eventually form visible celestial bodies. These bodies can range from simple rocks to meteoroids, planetoids, planets, gas giants, and even stars, with some gas nebulas acting as incubators for future suns.

So, what is gravity? It begins with the attraction of particles that grow into larger entities. But it doesn’t stop there. The aggregated particles—metals and gases—form solid bodies that continue to attract additional materials and magnetically charged rocks. Over time, these conglomerates evolve into larger asteroids and meteors until their mass becomes substantial enough to resist floating in the developing solar system, drawn in various directions by other forming planetoids. When the weight of the material becomes great enough, the center of the object experiences crushing pressure, leading to intense heating and the melting of iron within.

As this accumulating mass collides with other objects of varying sizes, it grows even larger. Even if the object fractures and integrates new materials with its iron core, it continues to expand and strengthen its magnetic pull. As this object travels through space, unable to escape the sun's grasp, it has the potential to traverse to the edge of the solar system or wander within the sun's gravitational field. When it reaches a significant size and speed, it stabilizes into what we recognize as an orbit.

Through collisions and orbital movements, the mass begins to spin. This rotation is often rapid due to the collapsed core of iron and rock heating up to extreme temperatures, causing surrounding rocky matter to melt into molten slag. This molten layer envelops the magnetically charged iron sphere, allowing it to absorb more iron and other metals, thus forming a core—a mixture of iron, metals, and rock, shaped by heavy impacts, rotation, and potentially orbit.

In essence, gravity is a form of magnetism. Every component of a planet originates from the remnants of a star's death. Any material added to a planet is simply part of the same matter that initially formed it, and everything contributes to its mass. The gravitational force of Earth reaches far, pulling in meteorites, comets, asteroids, and even other planets, alongside every celestial body within the universe.

The Relationship Between Gravity and Planet Size

Interestingly, higher gravity does not necessarily indicate a larger planet. Once a planet exhausts its material, its growth ceases. Earth possesses a gravitational pull rated at "1," which reflects our evolutionary path. The moon, with its significantly lower gravity, allows us to jump higher. If Earth were twice its current size during our evolutionary history, we would have developed differently, jumping higher on the moon if it remained unchanged.

It’s all about perspective. Nothing truly falls to Earth; rather, everything is drawn toward its center. Similarly, a dark star pulls matter toward it, showcasing that gravity is fundamentally a magnetic force, collecting anything that comes within its reach. While the Earth's superheated core maintains high temperatures within the planet, its surface remains cool. Without this intense gravitational core, continents would be immobile, akin to moons or planetoids like Pluto, which have solid surfaces marked only by significant impacts.

I appreciate you taking the time to read this. I hope it aids in your understanding of gravity and its origins. Reflecting on how planets form may also inspire curiosity about gas giants: what lies beneath those thick clouds? And consider the magnets on your keychain—do they pull at you? You encounter them quite often. Thank you, and take care!
