Star ship building: What elements are needed to build the ship?

AI Thread Summary
The discussion centers on the essential elements and considerations for future space travel, particularly in the context of creating a fictional setting similar to Star Trek's starship Enterprise. Key points include the importance of cheap faster-than-light (FTL) travel, which is crucial for maintaining industrial outposts at interstellar distances. Participants emphasize that the specifics of materials needed for spacecraft, such as carbon or titanium, depend on the intended use of the ship and the fictional science that underpins the setting. The conversation highlights that defining the capabilities and limitations of technology is more significant than the technical details themselves. Additionally, the feasibility of mining colonies is questioned, with suggestions that asteroids or small planets would be more practical sources for materials than traditional mining on larger planets. The discussion concludes that the focus should be on available resources and their applications rather than strictly on what elements are necessary for spaceflight.

Okay I have two questions that I plan to post separately. The first question is simple: what elements will be needed to further space travel in the future? Does anyone care to comment on what base elements would be necessary to build the starship Enterprise? I should explain the reason why I'm interested is because I like the idea of using mining colonies as a background for stories, and it would be a good idea to know what those miners might be mining.

If you want a setting with starships like the enterprise then you’re looking at a soft SF setting. In this situation defining capabilities and limitations is way more important than technical detail. The biggest thing is cheap faster than light travel. Not only is that a staple of how ships in Star Trek are used and designed it would allow for situations where it is economically feasible to maintain industrial outposts at interstellar distances.

All other detail depends on your setting. For instance: do you want there to be FTL communication separate to travel? If not then communication will be by courier and any polities will be more akin to age of sail nations.

Oh come now, certain elements are going to be necessary for spaceflight under any circumstances; Carbon come immediately to mind for building hulls. I don't know about Iron, but it occurs to me that if you need to hold your energy matrix in a magnetic field some element needs to be the base for that magnetic field. There have to be other elements and other applications that the folks here can reasonably speculate about.

Technobabble: you are doing it right! Exactly those elements are what's needed the most :wink:

Just tell a story, no one cares to read details about made-up technology. You are writing space fantasy (which is what star trek is) as it does take some real scientific background to write good hard SF

If you invoke the 'ONE impossible thing' waiver on 'Hard-ish Sci-Fi', choose your tech carefully, and be sure to map out the cascade of consequence...

Why should hulls be carbon rather than iron?

You don't need carbon for the hull. Metals can be used as well. In Star Trek: First Contact it was mentioned that the Enterprise is made from titanium. I don't think that there is an element that is essentially reqired for building a space ship.

Very broadly yes-ish. Life support, an airtight hull, electrical systems etc. Exactly what is needed depends entirely on what kind of activities one wants to engage in. The requirements of a transport designed to take astronauts between two different stations in orbit of the same world are going to be very different to a habitat capable of transporting a self-sufficient society across interstellar space for thousands of years.

Whatever fictional science exists in a given setting will change both the capabilities in demand and how they can be fulfilled.

The only defined activity you've stated is "make the enterprise". I'm not sure what makes you think that "carbon" would be needed automatically for the hull, beyond the fact that carbon is a very commonly used material. A fictional setting with a starship like the enterprise would also have to have a lot of fictional science to allow for faster than light travel/communication, artificial gravity etc. As I said above deciding on the limits and capabilities of these things are more important to a good story than the minutiae of how they work.

"Energy matrix" doesn't mean anything. It's technobabble. What it does and what it requires have to be defined by the author. Give it some capabilities (i.e. converts matter to energy) and some limitations (i.e. is 90% efficient) and you can begin filling out the details of how a starship would work in the setting (capable of being powered by any matter fed to the matrix but requires extensive radiators to deal with the 10% waste heat, furthermore starships are forbidden to approach populated planets to reduce the risk of an attack where in several kilos are fed into the matrix at once creating a devastating explosion. The social and political consequences of this are...).

Given starship-building of the Star Trek kind, it's unlikely that you're mining on planet, or that anybody could fund a mining colony because it's not economic. Expect asteroids, or even small rocky planets such as Mercury, being subsumed by nanofactories. The mined materials from an asteroid could be delivered via mass drivers with very little human oversight. Getting out of the gravity well of a small planet is harder, but energy overcomes gravity, and if you pick one in close orbit to its sun, you've a lot of solar radiation to power everything.

I'm not sure it's a matter of "what's needed", so much as "what's available and what can we do with it".
