Gravity

Gravity is a fundamental force in the physics of Realspace.

Workings
Gravity is the attraction between two objects, dependent on their distance and mass. All celestial bodies with mass project gravity, such as stars, planets, moons, asteroids, space stations, and star cruisers, with the larger bodies projecting more gravity. Gravity pulls objects towards the gravitational center, which is what allows for orbit, causes objects to drop or stay on the ground, prevents them from floating off into space, and cause minor time dilation, although it only becomes noticeable at incredibly strong intensities. Artificial gravity well generators recreate the effects of gravity, often at very strong scales. Gravity stabilizers, such as those present within standard spacecraft, serve to both create artificial gravity and to protect the crew from the effect of g-forces, which is even present within powervators and other lifts with high speeds. Tractor beams essentially function as concentrated gravity well generators, able to pull objects towards the emitter. The gravity that sufficiently large objects emit permeates into hyperspace in the form of pullfields, which can pull crafts out of hyperspace. Particles known as gravitons are able to create sophisticated anti-gravity tech, which need no mass to push against, unlike hovertech. The gravity of a given world can have drastic effects on its natives or extraterrestrial visitors. On a low-gravity planet, native land-based species could be tall and lanky, and be quite weak when compared to a native of a higher-gravity world, although they could also gain the ability to fly and hover with the world's weaker gravity. A human on a low-gravity world could find themselves able to jump many meters effortlessly, or throw an object a long distance, and an obese or otherwise large being would find themselves under less strain and able to move with ease. However, prolonged effects of staying on such a world would cause muscles to atrophy due to reduced muscle use. On a high-gravity planet, native land-based species would require strong, dense muscles and a durable body, often appearing shorter or bulkier than other species, and possessing what could only be described as super strength. Natives of extremely high-gravity planets are not humanoid, mostly being rather flat and extremely muscular creatures with many legs that are low to the ground, although this is not the case on planets with only somewhat higher gravity than the standard. A human on a high-gravity world would feel as if they are being pushed to the ground, find inclines difficult to climb up, and find that objects fall faster and with more force. However, prolonged residence on a high-gravity world could cause immigrated species to become more durable and far stronger than the rest of their race. Standard gravity worlds, at or near 1 g, are the most common among inhabited worlds.
