Ultrahomines: Rules

== General rules ==
* Spleehae is the founder of Ultrahomines and he has the final word at any debate or discussion regarding the settings.
* Do not try to find loopholes in the rules. Instead, point them out.
* Constructive suggestions are encouraged.
* Be civil, reasonable, and polite.
* If you are intending to add something that you think others might disagree, start a discussion regarding the topic before incorporating it to the timeline.
== Realism ==
* Be plausible.
* A logical explanation for even the most fantastic elements within the setting must be provided.
* New theoretical concepts and models are only permitted to be added to the timeline if they do not contradict other things that are already in the setting. Relatively recent discoveries and hypotheses are not allowed to be incorporated unless they have substantial and conclusive proof. Even if a concept has no evidence to support it, it can be added to the timeline if it passes the test of time (for example, if hypothesis A is here for some years and there is no evidence to prove or disprove it, someone could add it to the timeline).
* Those concepts regarded above need at least a mathematical basis, however. You cannot simply throw random unsupported ideas that come to your mind into the timeline.
* Be aware of the scope of space and time.
* The setting must conform to what is known and observed now.
== Point of view ==
* This scenario is written from the point of view of the modosophont (i.e., not transapient) populace, from the perspective of what sapients in the Civilized Galaxy know, don't know, and think they know and don't know. Knowledge of much of what exists outside this circle of safe sapient-friendly civilization, as well as knowledge of post-singularity entities, is therefore ambiguous, and deliberately left vague.
== Astronomy ==
* Planetary systems comparable to the Sol System are common, but many other planetary systems are quite different from our own.
* Rocky worlds are widespread, as are many other types of world.
* Brown Dwarfs are at least as common as other types of stars.
== Information Theory ==
* Reversible computing allows computation and computronium without excessive heat, though it doesn't do away with heat output altogether.
* The Bekenstein Bound holds, but can be circumvented by expensive wormhole buses.
* Bremmerman's Limit holds only for nano and larger scales, and given advanced clarketech is bypassed.
* The Holographic Principle holds. All of the information contained in a volume of space can be represented by a theory which lives in the boundary of that region.
== Physics ==
* The laws of physics cannot be broken. If you see something that might contradict our current knowledge of physics, please notify the administrators of the setting.
* Matter and energy are conserved.
* Relativity holds.
* Causality holds.
* Any form of faster-than-light motion or communication which breaks causality is not possible.
* Alcubierre drives are unable to move faster than light, but they can approach the speed of light.
* The Laws of Thermodynamics hold (on the macro scale).
* Exotic matter exists and, given transapient metric engineering, can be made stable.
* Wormholes are possible and are best be described as a modified Morris-Thorne-Kuhfittig metric.
* Lorentzian traversable wormholes are possible.
* Wormholes cannot break causality. If matter or information moves through the wormhole in such a way that it breaks causality, well, it will not. It will be ejected.
== Sociology ==
* Technology changes the nature of social issues.
== Technology ==
* Other species, societies, cultures, and individuals might find different solutions to the same problem. Try to make original technologies when addressing aliens or similar things.
* Picotech, femtotech, and even smaller technologies can only be operated by advanced post-singularity intelligences (usually AIs) and are rarely used.
* Clarketech may seem to break the laws of physics, but it doesn't. It is just too advanced for sapient minds to comprehend.
* Bionanotech is relatively easy to make and maintain.
* Dry (nonbiological) nanotech and its mature descendant hylonanotech are viable.
* No device is 100% efficient.
* Wormholes, space-time engineering, "reactionless" drives, and so on are viable, but require archailect-level technology (godtech) and intelligence to construct.
* Megascale engineering projects of many sorts can be achieved.
== Xenology ==
* Aliens do exist.
* Humanoid aliens are a minority in the cosmos. Body plans differ a lot, depending on the conditions that led to the evolution of said species. The galactical biosphere (or anything equivalent to it) is very diverse.
* There are no big obvious nearby alien civilizations, as implied by current negative evidence from SETI. They are rare and far away, but they do exist, and contact is viable.
* Life (at least the equivalent of prokaryotic-grade life) is common in the universe.
* Most life evolved naturally on its planet of origin.
* Panspermia is rare, but has occurred more than once.
* Natural Garden Worlds (i.e., Earth-like planets) and the equivalents of eukaryote-grade life are rare.
* Intelligent life is possible even in extreme environments.
* Most alien races are recent or only reasonably old; much older races are rare.
