Gravity Physics

 Newton's Law of Gravity is still in effect. No flying without use of an aircraft, no defying gravity in any way without the use of an aircraft.

 Synthesiser Physics

 The synthesiser does not violate the Law of Conservation of Matter. Simply put, the law means that a particle cannot be created or destroyed. Synthesisers can only put together objects using the particles that made up that object stored within a special datastream. Usually, only small objects up to the size of an M16 assault rifle can be synthesised. But industrial-strength synthesiser pads allow for larger and heavier objects to be synthesised. Only industrial-strength synthesisers can synthesise duranium (though when it does, the duranium is not synthesised completely and becomes a thin 'field' of strong particles while the rest depart into the air). Synthesisers can never desynthesise a person and reput him/her back together YET. It could be possible, but more detailed scanners for the synthesisers have to be invented and a larger memory capacity would have to be built. Even so, synthesisers cannot be transporters except to transport between two CONNECTED synthesiser pads.

 Weapon Physics

 Projectile weapons act the same way as real life guns do. Neurolasers on the other hand defy real life physics because of split-second antigravity. Normally, anti-gravity cannot be emitted from a small source, but the neurolaser rifle fires off a small beam of anti-gravity around the actual neurolaser beam to keep it intact against the forces of the atmosphere. Special exception to the rule of anti-gravity is shown in the anti-grav physics paragraph

 Anti-Gravity Physics

 Anti-gravity disables gravity inside it's 'bubble' field. Gravitons and anti-anti-gravitons therefore do not work within an anti-gravity field. Gravitons pull objects, anti-anti-gravitons push them away. Both are stronger closer to the source. Anti-gravity normally cannot be emitted from a small device, UNLESS: 1) the anti-grav field is small, like half-dollar sized small. 2) it is used in quick flash bursts that do not last longer than .001 seconds. Anti-anti-gravitons and gravitons can be emitted to any size depending on the generator. Anti-gravity, in order to create a stable field about the size of a standard hoverjet would require an emitter just about half the thickness of said jet. Anti-gravity pads are used in the floorboards of many space-born vessels to allow people to walk about like they would on the planet instead of floating around. These pads do not emit a field, but rather just a thick concentration of artificial gravitons within a single room. They can spread throughout the ship, though unless anti-gravity pads are placed under the floorboards of every room, the further one gets away from the pads, the more effect gravity will have on them. Anti-gravity fields are dangerous when in an environment where gravity is present ONLY when someone tries to leave the field bubble while in a place of gravity. The sudden change from floating to gravity can cause half of a person that is exiting the field on the side of the gravity to succumb to the forces of gravity and 'fall' while the other side floats unperturbed. This could result in severely breaking or losing a limb. Anti-graviton fields can be stabilized to almost any length with the addition of light particles, which would create a transparent looking field or object, such as the Ghost holograms that Shadow used in taking control of Area 41. These fields emitted from so small a source have to be empty on the inside, and in order to maintain the illusion of solidity, constant anti-anti-graviton pulses must be fired from the holoimager at regular intervals, especially when the hologram is interacting with any solid matter.

 Nanobot Physics

 Nanobots are the size of particles. Thus they have to use a source of sub-electrons to run. Since nanobots use a type of electricity smaller than the normal EMP can effect, special EMPs have to be used that could only affect small ranges and only nanobots. Otherwise, nanobots usually have strange disattachment effects when put under a normal EMP pulse or field, such as the case of Scarlet Ortensia. Nanobots cannot have a form of propulsion as there is no sub-particle known that can push an object forward. Normal anti-grav thrusters require a large amount of space for the engine. Both of these reasons keep the nanobot from flying through the air, but they can still quickly move by walking along a surface, or moving through a substance. Nanobots may even be able to use whip-like tails to 'bounce' themselves off of particles in the air towards a target, given the amount of particles in the air at the time and the rate at which the nanobot hits them (that can also be calculated into their speed)

 Anti-grav Thruster Physics

 The anti-grav thrusters used on the space ships rely on anti-gravity fields. When in the atmosphere, the thrusters alone can be used because there is an atmosphere of particles in which the anti-anti-gravitons being emitted from the thrusters can push off of. But in space, the anti-anti-gravitons must push off an anti-grav field. This usually means that when engines on a ship are off, they are unprotected by any sort of forcefield, though the power of the engines' anti-anti-gravity thrusters can usually crush a fast-moving projectile or energy orb very quickly. Smaller engines go slower, larger engines go faster, size being a determining factor along with mass of the ship in question to come up with an exact speed.

 Shield Physics

 There are two types of protective shielding used mainly by space vessels: Synthesised duranium and anti-anti-graviton shielding. Synthesised duranium is more powerful though more costly. It requires many large industrial synthesisers with at least 1 or 2 duranium walls desynthesised in each individual synthesiser. Since synthesised duranium is, in essence, a second (but invisible) hull, it can take more damage than anti-anti-graviton shielding can. But if the synthesiser from which the synthesised duranium is coming from is damaged or destroyed, the entire field breaks down. It is not electronic, and thus cannot be affected by EMP, though the synthesisers themselves can be (but only after the field is down so that the EMP particles can actually reach the synthesiser pad). Synthesiser fields have been used on the planet's surface since 2064, and the light particles tightly compacted in the atmosphere is what caused the field to glow, while in space it is normally invisible (though can be reflective like a crystal against the sun). Anti-anti-graviton shields are the kind that require the use of large emitters. They can quickly recharge, are not electronic (not even the emitters themselves are), and anything up to the size of a sidewinder missile would have little to no effect. Anything going slow, they push off, but anything going fast usually gets crushed (to the object being crushed, it's like a wall moving towards the projectile). Like a jello, fast and powerful hits against the shield will cause the part hit to 'squish' inward a bit, but after a number of seconds or minutes (depending on the power of the emitter) replaces this 'dent' with more anti-anti-gravitons. The shield therefore can be reused extensively even after hit, and can sometimes (if specially built to do so) spread the kinetic force of anything hitting against it across the entire length of the field, lowering it's damage effectively and spreading the damage thinly but evenly across it's surface. This would allow the shield to quickly replace the thin 'sheet' of anti-anti-gravitons taken out in the shot. Even after the emitters are destroyed, they can be recharged quicker than the synthesiser, since they are not electronic and do not require a slow and careful process of putting together particles in the right places. All anti-anti-graviton emitters do is emit anti-anti-gravitons to a set distance in big groups. All shields require large emitters and cannot be carried around by people.
