Origins of Water on Earth
There are many theories regarding the origins of the water on Earth. 71 percent of the Earth's surface is covered in water, yet we do not know where it came from.
It has been thought that the planet formed dry, as any water that was present would have evaporated in the intense heats of the Earth's early formation period and been lost to space during the process. Then, it has been thought, water rich meteoroids brought water to Earth.
This theory is extremely far-fetched, however; to say that the vast amount of water on Earth came from it being bombarded with space debris rich in water would imply an immense amount of space debris. Additionally, if this were the case, where are the other materials this space debris was made of?
The critical element that we are not looking towards is electromagnetism.
An electromagnetic field is more than just a "field", it is made up of infinitesimal particles. These particles travel as they do as a result of gravity, the one and only fundamental force. The Earth's electromagnetic field is a flow of infinitesimal particles traveling in Figure-8 orbitals by the force of gravity. Critically, the universe is infinite and comprises both infinitely large and infinitely small masses. These small masses, around a given body such as Earth, are pulled by the force of gravity. They then physically pass through the Earth, like a neutrino, and then out the other side, where the direction of gravity is then in the opposite direction. (See full description of how gravity causes all observations at https://www.cascadinguniverse.org)
When a body in space is not rotating relative to its surroundings, then when the infinitesimal particle passes out the other side of the body, it continues on a straight trajectory and reaches a distance of separation where it is no longer greatly influenced by the force of gravity of that body, and so non-rotating bodies do not produce electromagnetic fields, such as Venus.
However, when the body is rotating, all the mass around it is also pulled into this rotation. Due to the rotation, the infinitesimal particles do not travel directly away from the center of gravity. As they travel, the force of gravity then acts on one side of the infinitesimal particles' direction of travel so as to cause them to be pulled to a side and back to the center of gravity and thereby flow in a Figure-8 orbital.
Critically, when these flows of infinitesimal particles enter a given body, such as Earth, they converge at the center of gravity, as an electromagnetic field does.
It is at this convergence where the particles are most probable to combine into larger systems. Notably, these are infinitesimal particles and so in order for them to produce water, many of them must combine. At the core of the Earth, these infinitesimal masses have sufficient probability of interaction that a portion of them are able to merge together to grow into larger and larger systems due to this convergence of flows. From this, water is formed.
And so, over time, the Earth formed more and more water within its core, as hydrogen and oxygen are lighter elements their probability of being made was sufficiently high to be formed regularly. This, then, accumulated and pressures within the Earth pushed the relatively low density water outward where it would, in part, reach the surface of the Earth.
Due to this production of mass, the Earth physically expanded, in what is known as the "Expanding Earth Theory"
This is why what is known as "Pangaea", a single continent of all seven as one, fits together when the physical size of the Earth is considered smaller. The mere fact that the continents are combinable into one physically smaller mass demonstrates that Earth was a physically smaller mass.
It is generally considered that Pangaea had a large ocean, as shown here:
However, when this ocean is removed, the continents are able to be combined into a single, continuous land mass.
This is because they were a single, continuous land mass. Then, due to the production of water, and other materials, within the core of the Earth as it's rotation created an electromagnetic field which caused the creation of larger masses from the infinitesimal particles of the electromagnetic field, the physical size of the Earth grew and the oceans that we see today came to be.
The evidence is there before us; we need only be open-minded and consider possibility to see that this is the true origins of water on Earth.
