A: Factors that determine the geology of a planet (what factors determine the elemental composition of the planet) Rather than copying the list of resources to here, I suggest that interested parties browse the answer to this previous question (A list of worldbuilding-resources?) where an humongous long list of resources is to be found. You could do worse than start with this intro youtube vid to the solar syste... (more) |

A: Black hole as a storage device? Kugelblitz. If your weapon is mass/energy then yep you are in the right territory. If it's matter in a particular configuration (a complex piece that took hundreds of thousands of work-hours to make) you may be out of luck. Black-holes can be used as energy storage, using magnetic fields to spin th... (more) |

A: SFR Breeders on Small Mars Moon feasibility As I see it you have 3 issues here: Gravity. Normally sodium circulation would occur because of a temperature/density gradient which facilitates convection to carry it through the heat-exchange cycle. In minimal gravity the circulation would be crippled without a pump, both for the core->sodium h... (more) |

A: How many years before enough atoms of your body are replaced to survive the sudden disappearance of the original body's atoms? Even if they survived Zeiss Ikon's way, there's not a hope of surviving this: The neurons in the brain don't get replaced over this sort of time period. It is widely understood now that new neurons can grow, but when a nerve cell dies, it is gone for good. The nerve cells in your brain today have th... (more) |
