How would the "Hardness vs Toughness" dynamic of gems apply if it were possible to make shields out of them?
Toughness is more important in a shield
Toughness refers to the amount of energy necessary to deform a material. A tougher material will be able to absorb harder blows without being damaged, and if it ...

How would the "Hardness vs Toughness" dynamic of gems apply if it were possible to make shields out of them?
There are several issues when designing a shield.
What is a shield? It is something that protects you against some incoming weapon. It can do that by deflecting the weapon, by absorbing it, or by ...

Would the calculus change if we went from medieval weaponry to say, cannons or modern firearms?
Yes.

Speed of light in higher-dimensional space
If there are more dimensions, it won't change the speed of light. How hyperspace works is that you shift to a space where the distance between two points is shorter.
Consider a person running across ...

It depends on a technology level, intended audience and required longevity. E.g. you could drill a hole into the base and hide a flash disk or a nfc tag inside.
Or you pick up your chisel and hammer ...

Would the discovery of a room temperature superconductor with a high critical current improve ion drives?
The real issue with things like VASIMR and other electromagnetic thrusters is not so much the rocket bit, but the amount of power it takes to operate the things. Unless you're visiting the inner solar ...

This is possibly a frame challenge answer.
The point of a hiding place for something is to distinguish between intended and unintended end users of the thing. Actually storing ...

How close to a star could a dense asteroid belt reasonably form?
There are a few misconceptions in this question. The first is that there's anything that we could call a typical stellar system, but we'll ignore that in favor of the popular idea that systems will ...

Would the discovery of a room temperature superconductor with a high critical current improve ion drives?
Probably!
The really cool thing about superconductors is that they have exactly zero resistance - hence the superconducting properties they have. In an ion engine, you’re dumping kilowatts of power ...

Its mostly gravity and the outcome of planets forming or gas-giants preventing the same, that affects the stability of asteroid belts.

Would the discovery of a room temperature superconductor with a high critical current improve ion drives?
Why wait for 'room temperature' superconductors? The background temperature in space is about 2.7 Kelvin. If you shield from the sun, this is cool enough for most conventional superconductors.
Don't ...
