A: Could DNA Survive in Outer Space? Traveling outwards from the Earth in plastic bags in a tube, it would survive minutes, 'till the bags heated up in the solar radiation, burst and the whole of the inside of the tube was filled with mixed blood clotts, melted plastic and superheated steam (over 200C - 390 F in direct sunlight), the pr...

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...

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... (more) |

A: Need a specific event that wrecks the surface, allows the race to survive in bunkers, and affords an aftermath suitable for them to rebuild Nearby Supernova. Dr. Mark Reid, a senior astronomer at the Harvard-Smithsonian Center for Astrophysics stated: "¦ were a supernova to go off within about 30 light-years of us, that would lead to major effects on the Earth, possibly mass extinctions. X-rays and more energetic gamma-rays from... (more) |

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... (more) |

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... (more) |

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 ...

A: Asteroid material that can cause signal distortion Asteroid material that can cause signal distortion. Antimatter clusters at the Heliopause Physicists have long puzzled why there is so little apparent antimatter in the universe - surely equal ammounts of matter and anti-matter should have been created at the big bang yes? It turns out that in... (more) |

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.

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... (more) |

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)... (more) |

A: How can an individual that consumes the biomass of others not experience any weight gain? 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...

A: Would a society with two different species that can interbreed be viable? Would a society with two different species that can interbreed be viable? Sure it's possible, by a number of processes the most obvious being hybridisation. The process by which two distinct species combine to form mostly infertile offspring (Vis-a-vis mule)- but just occasionally they are viable. ... (more) |
