Why developing artificial gravity is possible right now.jpg

If we had the technology to create spacecraft or space stations with artificial gravity, or to terraform the Moon to have the same gravity as Earth, it would be a monumental achievement recorded in history until the end of humanity. But we can realize it right now.
To do that, we first need to understand how Earth came to have gravity.
Before Earth was formed, our galaxy experienced a collision between two massive objects, and as the fragments spread out, a stable galaxy was formed. At that time, our solar system likely had many more planets and asteroids.
Over time, as their orbits met over hundreds or thousands of years, they collided, creating the stable solar system we have today.
In fact, the Moon and the Earth were once a single substance. In terms of DNA, they share the same parent.
If they had changed by coming into contact with a third substance from another galaxy while separated into the Earth and Moon, different DNA would have been discovered. But the important thing is that the Moon, the Earth, and the Sun were one substance before the collision.
So, getting to the point: Earth, which was once a star, underwent nuclear fusion and fission to create a stable iron structure. By emitting heat through radiative cooling, the momentum of atoms decreased, causing space to contract and generating gravity.
Therefore, using the same principle, I intend to try making a bead with artificial gravity on Earth.
We prepare a bead with a diameter of 10M.
Then, we fill that bead with 30% water and turn it all into water vapor.
After that, we cool it down. It is said that gravity does not increase by the amount of (ratio of water vapor converted to liquid) × (mass).
The reason is that while it contracts space, the expansion pressure of the other water vapor is greater, canceling it out.
So, let's install a pressure relief valve and discharge the water vapor until it reaches an appropriate pressure.
From that point on, the gravitational force increases by the amount of (ratio of water vapor converted to liquid) × (mass).
Here, there is a concept called "Gravity Conversion Limit Mass."
If there is a substance higher than the Gravity Conversion Limit Mass per unit volume, gravity will not increase even if you convert the water vapor into liquid.
However, if you make it lower than that mass, gravity increases as the water vapor converts to liquid.
So, we put in less than 5% water, turn it into vapor, cool it into liquid to create gravity, and then take that liquid out with a pipette, reheat it externally to turn it back into vapor, spray it into that capsule at low density, and let that vapor be cooled by a refrigerant.
Even here, you can only make the gravity inside the bead increase if you spray it at a level lower than the Gravity Conversion Limit Mass per unit area.
By converting water vapor to liquid to increase gravitational force, turning that liquid back into vapor to spray it, and repeating the process where that vapor becomes liquid via a refrigerant and is then extracted and turned back into vapor, the artificial gravity inside the bead continues to grow.
In the case of Earth, gravity increases when water vapor turns into liquid in a vacuum layer where there is no atmosphere. In an atmospheric layer with a lot of air—that is, a place where there is more substance than the Gravity Conversion Limit Mass—no matter how much water vapor you convert to liquid, it cannot affect gravity.
In reality, the increase in gravity occurs not in the atmospheric layers of planets or stars, but in the vacuum layers at the gravitational boundary, such as the thermosphere.
So, when terraforming the Moon, we increase the gravitational force by converting water vapor into liquid in places that are under the Moon's gravity but are in a vacuum.
Now, we manufacture gravity beads in a factory.
We create beads with internal gravity 100 or 1,000 times greater than Earth's gravity, and we increase the gravitational force by opening these beads inside.
Suppose A is a planet, B is the atmospheric layer, and we build a massive pillar at C. This pillar is so high that air from the atmospheric layer cannot enter; it is connected to a vacuum layer.
If it were as low as the height of the atmospheric layer, it would be filled with air.
However, if we put a bead with 1,000 times artificial gravity inside and open it, the gravity of this planet increases.
But if this space is filled with air, even opening the 1,000x bead will not cause any change in the planet's gravity. It will just create atmospheric flow.
Winds will blow and the planet's atmosphere will surge.
So, the movement of Earth's atmosphere occurs when gas converts to liquid; the force that contracts space when water vapor becomes liquid and falls.
That force is what creates wind and atmospheric flow.
This force can also be used to create gravity.
I made this diagram to help explain this.
So in the future, gravity beads will be mass-produced in factories, placed into these large towers, and then opened and replaced.
We can increase the gravitational force by docking them.
A gravity bead is also a planetary capsule.
Inside a 10M diameter bead, we create something about twice Earth's gravity, add liquid, and add water vapor.
Then, we break it in the outer space vacuum layer where Earth's gravity does not reach.
The broken hole then becomes the gravitational boundary. At this time, if you melt the bead with a laser, the bead will be pulled by gravity, form a core according to density, and then become a small planet made of liquid and water vapor on top of it.
In this way, we can terraform the Moon or create spacecraft with artificial gravity. When people think of creating spacecraft with artificial gravity, they usually think of making gravity act only inside the ship.
If you build it that way, you cannot use the spacecraft properly.
Therefore, you must build a planet-type spacecraft.
The planet is about the size of Earth.
Inside, a massive amount of liquid is arranged like a planet due to gravity.
And spacecraft where people reside are attached to the surface of the spacecraft. It is in a belt form.
The center of gravity is the liquid planet. You are pulled toward it. Even if all that liquid is released, you are still pulled toward it naturally.
If you put in iron, the iron will pile up at the center due to buoyancy, and the liquid will pile up on top of it.
The space stations we know are circular, but if you create gravity inside them, the center of the interior becomes the gravity point. So, in movies, instead of walking, you would be floating in the middle. In that middle point, if you go up, you go down, and if you go down, you go up—you would be in a strange circular cave-like environment.
That is why we must build planet-type spacecraft. Technically, this can be built, but it is a futuristic technology for which we cannot simply conclude, "It will be possible in 1,000 years" or "It will be possible in 10,000 years."
However, since it is possible to travel through space faster than the speed of light, using photon propulsion, we can travel at 100 or 1,000 times the speed of light, and these planet-type spacecraft could even create colonies 100 million light-years away, beyond Earth and the solar system.
It is an achievement that will take at least 100 million years. But looking at the current rate of development, it is even possible to say such things.
If Korea achieves this, reaching a KOSPI of 1 million is also possible. But since this is such a massive project, the US, Europe, and all countries in the world must participate.
