Interstellar Travel Could Be Possible Even Without Spaceships, Scientist Says
- rbanffy 4y agoStill a spaceship, regardless of the building materials. Hauling a planetary mass, however, is far from practical. Ideally you'll try not to carry too much extra mass and planetary masses increase at a power of 3 while usable volume increases by a power of 2. You want something where the usable volume scales with the mass. OTOH, if you can use the planet itself as reaction mass, then you can afford a lot more initial mass, but there won't be much of a planet left when you finish braking.

- rbanffy 4y agoI'm done with terrible bosses.
- graderjs 4y agoTho thinking about what you said more, how do you figure? Mass = Density * Volume, so they increase at the same rate. I think you may have meant surface area. When I read this article I assumed they would be using the space inside the body, like a hollow or honeycomb moon
- rbanffy 4y ago> like a hollow or honeycomb moon That's an interesting idea, but it means a significant effort in reshaping the planet. By then, it's definitely a spaceship.
