Can we detect relative high ground-levels of radiation from Orbit? Would an Astronaut on the ISS holding a geiger-counter into the general direction of Earth when passing over Tschernobyl or Fukushima get a heightened response compared to the Amazon rainforest?	1643
Does space expansion occur uniformly in all directions and dimensions?	42
Are the oceans that are connected all equally salty, or do the salt contents differ by region? If they do, why haven't they "balanced" within the million years of their existence?	1
What is the largest (read most faced) non-platonic solid that approximates a sphere that has been described mathematically?	1
If a meteorite of cataclysmic size were to hit the moon, would there be immediate consequences for earth, or is the moon at a somewhat safe distance?	1
Based on all information we have from previous impacts to the lunar surface, what are commonly agreed upon consequences to life on earth if a meteorite of cataclysmic size impaced on the moon? Have there been studies on the entanglement of lunar surface activity and terrestrial activity?	1
Has there ever been a verified instance of a real-life self-destruct-system? Or is it one of those totally made up movie/game tropes?	1
Will a body submerged up to its neck in drinking quality water dehydrate?	1
Is there an equation that describes a cratered sphere? Can similar to adding N sinous graphs of different amplitudes to create infinite different 2 dimensional shapes the cartesian formula be theoretically altered enough to (almost) perfectly describe the shape of the moon?	1
The Earth is shielded from harmful solar radiation by the magnetic field generated by the planet's core. Would it be possible to artificially generate a similar magnetic "shield" to protect future manned space missions that go beyond earth's orbit?	1
