Introduction The fundamental idea of the MWI, going back to Everettis that there are myriads of worlds in the Universe in addition to the world we are aware of. In particular, every time a quantum experiment with different possible outcomes is performed, all outcomes are obtained, each in a different world, even if we are only aware of the world with the outcome we have seen. In fact, quantum experiments take place everywhere and very often, not just in physics laboratories: There are numerous variations and reinterpretations of the original Everett proposal, most of which are briefly discussed in the entry on Everett's relative state formulation of quantum mechanics.
Stealth technology, small cargo hold, and a propulsion bus with high acceleration You get the idea. A warship's payload section can include anti-spacecraft weaponsorbital bombardment weapons for revolt suppression type spacecraft as wellweapon mountsweapon control stations, combat information centerarmorpoint defenseweapon heat radiators and heat sinksand anything else that can be used to mission-kill enemy spacecraft.
Pirate ships and privateers might forgo defenses if they only expect to be engaging unarmed cargo ships. But they will regret this if they have the misfortune to encounter armed enemy convoy escort ships or are surprised by a Q-ship.
One section is the propulsion bus — drive engine, reactor if any, solar wings or radiator fins, propellant tankage, and a keel structure to hold it all together. The other is the payload section that it pushes along from world to world.
There are both conceptual and economic reasons to treat them separately.
Conceptually, because a propulsion bus might push many different payloads for different missions, such as light payloads on fast orbits versus heavy payloads on slow orbits. A little noticed but important feature of deep space craft is that you cannot overload them. They do not sink, or crash at the end of the runway, or even bottom out their suspension.
They merely perform more sluggishly, with reduced acceleration and for a given propellant supply less delta v. Conceptual logic is also economic logic. The outfits that build drive buses would like to sell them to lots of different customers for a broad range of assignments.
This is not necessarily an argument for true modular construction, with drive buses hitching up to payloads on an ad hoc basis like big-rig trucks and trailers. Building things to couple and uncouple adds complexity, mass, and cost — plug connectors, docking collars, and so forth.
Moreover, drive buses intended for manned ships need to be human-rated, not just with higher safety factors but provision for supplying housekeeping power to the hab, etc.
The trigger event has to be North Korea North Korea is the most rogue element in the world and yet it’s been given a pass by the U.S We don’t do anything to stop its nuclear progress, unlike Iran. Now is an appropriate time to carry out a new Situation Analysis, as UNICEF and The Government of The Gambia Country Programme of Cooperation – is in its second half of implementation and preparations for a new country programme have been initiated.

But these things, along with differing sizes or number of propellant tanks, and so forth, can all be minor variations in a drive bus design family. The payload we are most interested in is, naturally, us.
The main habitat section of a deep space ship closely resembles a space station. It is likely that habs intended for prolonged missions will be spun, for health, efficiency, and all round convenience.
The design of a spin hab is dominated by the spin structure and — unless you spin the entire ship — the coupling between the spin and nonspin sections. Because ships' spin habs have the features of stations they may be used as stations, and again we can imagine design families, with some variants intended for ships and others as orbital platforms having only stationkeeping propulsion.
Habs are the one major part of a deep space ship that correspond fairly well to our concept of a hull. Spin habs are entirely different in shape, but the shape is constrained; once you build it you can't easily modify it, beyond adding another complete spin section.
For those with bank cards at the ready, buying a deep space ship might be not unlike buying a computer. If your mission needs are fairly standard, you check off options on a menu. Those with more specialized requirements can select major components — perhaps a drive bus from one manufacturer, a main crew hab from another, along with custom payload sections, service bays, and so forth, assembled to your specifications.
In fact, both technology and probable historical development suggest that fabrication and overall assembly will be two distinct phases, carried on in different places, quite unlike either shipyard or aircraft assembly practice.
In the early days, large deep space craft will be built the way the ISS was, assembled on orbit out of modules built on Earth and launched as payloads. In time fabrication may move to the Moon, or wherever else, but final assembly at least of larger craft will continue to be done at orbital facilities.
I call them cageworks, on the assumption that a cage or cradle structure provides handy anchoring points for equipment.
For game or sim purposes, my advice would be to treat drive buses and hab sections as the primary building blocks for ships, whether these components are permanently attached to each other or simply coupled together. Both approaches might be in use.
A couple of provisos.How many nuclear power plants are in the United States, and where are they located? There are 61 commercially operating nuclear power plants with 99 nuclear reactors in 30 U.S.
states (the Indian Point Energy Center in New York has two nuclear reactors that the U.S. Energy Information Administration counts as two separate nuclear plants). In the section Ship Design Analysis we will examine what spacecraft warships will need, what they won't need, and what sort of tasks they will likely be required to perform.
In the section Ship Types we will examine the thorny issue of the terminiology of the various types of spacecraft. Asymmetric warfare; Broken-Backed War Theory; Court-martial; Cold war; Deterrence theory; Horses in warfare; Irregular warfare; Law of war; Mercenary; Military campaign.

Nuclear Basics our analysis shows the potential contribution nuclear can make as a dispatchable low-carbon technology. WEC’s World Energy Resources report released in the same month showed that total global renewable energy.
This is strikingly beautiful – one of the best I’ve read from you. One somewhat rambling thought I took away from this post, oddly enough, is that – in the face of a potential superintelligence – the status quo is not the only alternative to trying to build a Friendly AI.
