So, as a person who tries to keep their science fantasy within shooting, if not necessarily shouting, distance of our locally-applicable universe's rules, I often have weird lines of inquiry in the name of """realism""" and the like. Many of these lines of inquiry are the sort which Wikipedia and its underpinning sources can assist in answering, but many others are... a little more specific. Cases in point:
How much does the average human thumb weigh less the associated bones?
At what depth in the Earth's crust can one realistically expect to have enough insulation to survive the extinguishment of the sun?
What sort of economy would evolve in a society where affection is a tangible substance which can be manufactured, consumed, or stolen?
Could a gyrocopter be designed so as to function underwater as well as in air without reconfiguration between the transition?
Are there any resources out there (and OUT THERE) that people occasion for the purposes of either getting answers or at least finding directions on pseudo-believable answers to equally stupid queries?
