Question	—	Time passes only if an observer sees Based on the situation described by this earlier question: recap If due to some strange phenomena that changed our universe laws, time stopped and can only move if a creature capable of observing is looking at a process. Everything stopped everywhere in the universe, except where creatures with eye... (more)	—	over 9 years ago
Question	—	Plants made out of metals Carbon dominates the makeup of life on Earth. But is there any way that plants could be made out of metals, or somehow integrate metals with their constitution? For example, we use calcium in our bones, which is an alkaline metal. Its there any way that a plant might use metals (alkali or otherwis... (more)	—	over 9 years ago
Question	—	Surface temperature of a icy rogue planet A certain imaginary stellar system had once a water world. But instead of evaporating away under the stellar wind, this lucky (or unlucky?) water world (made of only water and a gaseous atmosphere) interacted with a huge gas giant planet and got expelled from its parent stellar system. Now this plane... (more)	—	over 9 years ago
Question	—	Explosive plants Plants in our world evolved various kinds of defenses, like poison, urticating hairs, thorns etc. What i dont see is plants that defend themselves by means of explosions. The explosion by itself can stun or scare a herbivore and dennounce its position for possible predators, while on later stage of... (more)	—	over 9 years ago
Question	—	Taming wormholes An ancient civilization mapped wormholes when the universe was quite young and smaller. This allowed them to reach other galaxies (wormholes from our galaxy to others). They mapped it all. Humans found their maps in recent times, and now humanity is able to reach anywere in the universe thanks to th... (more)	—	over 9 years ago
Question	—	Could life in a planemo be sustained by cosmic background radiation? I need to create a race that should be utterly older than humanity (and as such, much more powerful). My idea is to have that race originate from a rock planemo - a rogue planet, orbiting the center of the galaxy without a star. The idea is that this planemo originated so long ago that the cosmic b... (more)	—	over 9 years ago
Question	—	Black hole launcher Humans developed a new weapon: Black hole launcher. How it works: A mobile particle acelerator acelerates two particles to huge speeds and collide both. A mini black hole is created. The mini black hole flies throughout a barrel containing a magnetic field, again accelerating (the original partic... (more)	—	over 9 years ago
Question	—	What is the best way to exploit the energy from a red dwarf and send it to other systems? Scenario: Earth men colonized Alpha Centauri. Barnard's Star is at range. There is a huge fleet of fission bomb pulse propulsion cargo ships. Given Enough time and space they can reach 0.8C. Question: Barnard's Star has no planets to colonize. Would it be possible to use it to collect energy? If... (more)	—	over 9 years ago
Question	—	Interstellar communication Scenario: Earth men colonized a terraformed planet orbiting Alpha Centauri. There are already industries developed there, farms, mining etc. There's a large fleet of cargo ship capable of reaching 0.8C (over long distances - nuclear pulse propulsion) serving both systems (colonies both in our Solar ...

Question	—	Interplanetary electron gun How feasible would it be to use a huge electron gun to pump electrons from a solar array positioned close to the Sun back to Earth or Mars? My idea is to create a eletrical circuit by means of using electrons discharged from a huge solar array positioned very close to the Sun. Each side would have a... (more)	—	over 9 years ago
