Answer A: Would a portal to space enable propulsionless orbital launch
AtmospheriPrisonEscape's answer in this thread gives us the equations needed to calculate velocity at any particular orbital height: Any small mass $m$ orbiting a large mass $M$ has its centrifugal force balancing gravitational acceleration exactly, so that $$g = \frac{v^2}{r} $$ and the...

Question At great altitude, what conditions are needed to support a human community?
In my part of this (Earth-like) world, there is a stable community of completely isolated pre-industrial humans, numbering perhaps 1,800. They live at an altitude of (at least) 25,000 feet (7620 meters) in a very high inaccessible valley, possibly adjoining the caldera of an extinct volcano. What g...

Answer A: How difficult would it be to turn the Asteroid Belt into a single body? What's the best method?
Probably not all in one go, but along the way why not have some fun, save your job and give the Emperor something to smile about. Say you have a sixteen space tugs to work for you - first thing first, order 12 of them to pop out to the Kuiper belt and drag in a dozen matching 100 Km diameter KBO's (...

Answer A: How much heat would a 1km asteroid release into earth's atmosphere?
When an asteroid or comet impacts the Earth, the energy released mainly depends on the mass and velocity of the impactor. Using your figure of 100m diameter, an angle of 90 degrees (ie. coming straight down) and a density approximating iron @ 2.6grams per cubic centimetre, an impact velocity of a m...

Answer A: Interplanetary/Interstellar World Blight
The organism first erodes bedrock into verticle shafts, tens of meters deep. Through a series of complex metabolic processes it begins to generate a build-up of waxy deposit at the bottom of the shaft - this grows, till it fills half the shaft then stops. Next, like an iris closing, the top of the s...

Answer A: What would make radio transmission unfeasible on a planet?
What would make radio transmission unfeasible on a planet? Fierce Geomagnetic Storms. A non lower-atmospheric solution is a very active sun that releases more or less continuous flares which beat on the upper atmosphere - as they do on Earth in an eleven year cycle - but if the ones squirting o...

Answer A: What would happen to a human body subjected to extreme water pressure?
What would a death by extreme water pressure look like? Cort Ammon's answer is quite correct, as is Andrey's. I'll add a bit more science and some idea of visuals. 1000 metres depth. The pressure here is about 100 atmospheres, Cort Ammon's answer applies as-is. 10,994 metres depth. Mariana Trench ...

Answer A: How Long Would Artifacts Last Under the Moon's Surface?
How Long? I concur with the other two answers in that everything could be potentialy functional if sufficientley shielded from hard radiation and strikes by macroscopic particles. However we need to look at several potential problems: Tectonic activity on the moon - until recentley it was thought ...

Answer A: Is it possible for an organic species to generate a steady magnetic field?
Is it possible for an organic species to generate a steady magnetic field? Hemochromatosis: The human body cannot rid itself of extra iron. Over time, these excesses build up in major organs such as the heart, liver, pancreas, joints, and pituitary. Iron is ferromagnetic in it's metalic el...

Answer A: How fast would a Martian space elevator travel?
What is the maximum G-forces someone can stand COMFORTABLY? I posit that in order for someone to experience comfort that they must remain conscious, so the method by which people are transported having been rendered unconscious is out. I would suggest a G-Suit. (More accuratley an Anti-G-Suit)...

The host takes what it needs - except the essential element that the Symbiote needs a constant supply of. The Symbiote's alien biochemistry means the same things the host needs are sustaining - but there is still one essential craving, need and urge driven by a chemical deficiency. The Symbiote's c...
