The Physics of Gravity


A Description of the Principles behind the Extraordinary Force of Nature 

The Gravity of the Steamopera

Background

After Newton had discovered the main principles governing the spheres of the universe, it was believed that nothing much more could be added to the knowledge of that time. This was completely wrong, as was discovered in 1767, when the Great Celestial Storm began.

In 1767, the Solar System had entered an area of inter-stellar space where a rogue object was treading its way against the galactic current. This object must have been a large, terrestrial planetoid, flung from some unknown star's embrace into the void, only to intersect with the course of our Sun. The planet, commonly known as Nemesis, was shattered as it entered the orbital space of Sol, and its pieces were scattered in an elliptic orbit around the sun in a spectacular display of astronomical gaudacity.

It did not take long for people to discover this orbit overlapped that of our own.

And thus, each year, in June-July or December, the Earth is showered with a veritable bombardment of meteors and asteroids: some years not at all and some years in devastating amounts.

But what truly marks this act of God from others was that Nemesis, unlike most of the planets of Sol, was antibaric. Though it was still attracted by the alpha-neutral gravity of the Sun, it repulsed the gravity of Earth: and people discovered that not all that goes up must come down.

Probaricity and antibaricity

Every school-boy knows what antibaricity is. Antibaric matter is a normal kind of matter with a gravital charge opposite of that of terrestrial matter: it has levity. Antibaric matter is, naturally, attracted by matter of its own gravital charge, and also by the two "neutral" charges, alpha-neutral and beta-neutral, but it repulses, and is repulsed, by the particular probaric charge of Earth stuff. These kinds of matters are often called probarides, antibarides, alphaneutrides and betaneutrides.

If you arrange nodes that represent the four different gravital charges into a diamond, and connect each corner with another (see figure), you can tell which gravity repulses and attracts another. Each charge repulses only one other charge, and attracts itself and the two others: probaric and antibaric, and alphaneutral and betaneutral charges form such pairs: our own terrestrial probaricity attracts itself, alphaneutral and betaneutral gravity, while repulsing antibaricity.

Gravital charges are an intrinsic part of matter, and we do not know any way of changing it. It is probable that graviticity is something that is created in the birth of matter, in stars and our Sun, which would mean that the energy needed for such modifications is yet out of our reach.

Behaviour of antibaric matter on Earth

In practice, most antibaric stuff on Earth is diluted, mixtures of antibaric and other kinds of matter, or otherwise held down by matter with a probaric-compatible charge. This is logical: if 'tweren't nailed down, antigravitic matters escape gravity-wells with full speed. Planets tend to be made out of one or two materials - if any more, they tend to break apart.

Naturally though, there are traces of all kinds of gravital charged matter found on all planets, only in very small amounts. Earth is made out of 98 percent Terrestrial matter, probaric, the rest of which is alphaneutral with very small amounts of antibaric matter and even smaller amounts of betaneutral matter (which is repulsed by the alphaneutral gravity of the Sun!).

Nemesis, then, was made out of antibaric matter and betaneutral. When it entered our system, it was broken apart by the simultaneously attractive (towards antibaric) and repulsive ( towards betaneutral) gravity of Sol (alphaneutral). Much of the betaneutral-rich matter of it was immediately flung out of Sol System, but some of it remains attached to antibaric matter.

When an item of antigravital charge is released on a larger object, it falls upwards. It accelerates at the same rate a progravital charge element would accelerate in the opposite direction, so if you 'drop' a ball of antibaric matter on Earth, it'll fly upwards, accelerating at about ten meters per second. As it flies further, this acceleration will lessen, and the further the antibaric object is from Earth, its acceleration will become close to zero: but naturally, it never slows down except if intercepted by some other object.

Abaricity

When an object is abaric, its gravital charge, relative to gravity field it is in, is somewhere close to zero. What this means, that the matter in question is actually a mixture, or collection, of two kinds of matter, one of which is repulsive, and the other which is attractive to the larger gravity field. Theoretically, an abaric object would not be acted by any sort of force from the larger gravital field, which would mean it would follow its kinetic tangent and fly into space due to the rotational force of planets around the axises and orbital motion around the Sun. This is in contrast with antibarides that would actively fly away from their point of origin.

In common usage, abaricity is a term used for any object which is a mixture of opposing gravities. Practically this means that an abaric mixture of probaric and antibaric matter acts as if it was an equivalent uniform object which is on a planet with lesser gravity. If on Earth you'd have an abaric ball with two sixths of antibaric content, it's overall gravity would be one sixth, and it would act like an object of the same mass would act on a planet or moon with one sixth of Earth's gravity - that is, the Moon.

Of course, there is still a further complication beyond this when you consider the effect of being submerged in an atmosphere on an abaric object. If the object is made out of light substances, or as a mixture of light materials with heavy antibaric materials, the perceived density of the object drops. This means, that even when the antibaric content of an object is much less in weight than the counterweight found in probarides, the object in question may be large enough in volume and low enough in probaric weight to become lighter than the air in the atmosphere!

This effect is used in aeronautical flight for antiballast used on flying craft. Even when an accident occurs, and the antiballast tanks are lost to the sky, they are still only buoyed by the difference in density. Thus, instead of losing precious antibarides back into space, from whence they may never return again, the antiballast tanks will stop their ascent as the pressure drops with altitude, leaving them floating on cold winds until collected to safety.

Thus the application of abaricity is an art in itself. In adorbital engineering, where abaricity is used on elevator-ships between planet surface and orbit, the creation of different kinds of uses for antibaric matter is a matter that captures many imaginations. There are dozens of standard ways devised to create abaricity on a ship, from the mixture of antibaric and probaric matter in the building elements of the ship, and the use antiballast that can be reused easily. There are good and bad sides to all these designs, and this is what makes abaricity such a fascinating subject.

Chemical mixture

Because there are no other fundamental difference between matters that have different kinds of gravital charge, they can form chemical bonds with elements of opposite baricity. Thus, as a simple example, you can bind antibaric hydrogen (notoriously hard to hold down to Earth due to the way it tends to find a way to escape vessels made out of materials that are not porous to other elements) with probaric pyrogen to form "light water", H2.Py, water with identical chemical properties to ordinary water, except for its weight which is about 40% of that of ordinary water.
