Answer	—	A: How can we grow this community? I don't see a Facebook page link. Any other social media. Simply having a presence there will give some people more trust. Occasionally making a post when a new forum or feature is enabled would be cool. I have not spent much time here because so much regulations to achieve perfection instead o...

Answer	—	A: How would an interstellar spaceship's speedometer work if everything else is moving? You would send out a small laser or radar retroreflector out of the side of your ship and observe the tracking angle. Knowing the speed of your marker you can calculate the speed of your ship with reasonable accuracy. For large scale relative velocity you would use stars with known vectors and ca...

Answer	—	A: What is the most efficent way of killing prey much larger than yourself? The Honey Badger is known to kill water buffalo by ripping out their scrotum and letting them bleed out. Mostly out of spite I think for being disturbed, they mostly eat small game, honey, bee larvae, insects. Something evolved to eat large prey has to be a pack animal or it would be a waste of f...

Answer	—	A: Could grow lights on a massive scale replace 100% of sunlight for 100% of the growing season? There are multilevel automated food plant farms in existence that are artificially illuminated. Sure they may use skylights but they have many times the growing area so the plants are not getting full sunlight that way. There are lots of underground growing systems that are in old mines that are ... (more)	—	over 2 years ago
Answer	—	A: Important resources for Dark Age civilizations? Good points all and valid. Civilisations of the past have failed when they outgrew their local resources, usually wood in the limit as it is impractical to transport over large distances. However you show a medieval island that is small if the features that look like mountains are mountains. So th... (more)	—	about 5 years ago
Answer	—	A: How can my powered armor quickly replace its ceramic plates? Temporary patches to cover weak spots and crumble away after an hour or two. Provides protection while the damaged spot can self repair and patch provides additional protection while still in place after repair in direction of fire. Patches can be bulky and double thickness to be flexible and fit o... (more)	—	about 5 years ago
Answer	—	A: Why would people living inside a nebula go into space? A similar story has been written (a mini epic really over many generations) that has a civilisation living inside space that was doomed to become uninhabitable due to excessive cosmic junk in the vicinity. Scientists in your Nebula Planet may correctly surmise that conditions will change too fast fo... (more)	—	over 5 years ago
Answer	—	A: What conditions would make having them sunken into the ground the predominant way of building large structures? The most plausible reasons are solar radiation protection (sudden flares) and thermal management (less sun facing surface) as in the answers by hyperion4 and CatCat. Basically unless you decide that the environment has a inconvenient sun you will have to make some other reason that the surface must ... (more)	—	over 5 years ago
Answer	—	A: Is it possible to rule a galaxy without mastering teleportation? There is no way for a galaxy government to work without faster than light something. The obvious requirement for creating the society are faster than light travel but this can be dispensed with if the expansion is at sub-light speeds. Teleportation at FTL speeds would fix the problem as well as FTL... (more)	—	over 5 years ago
Answer	—	A: Could an advanced alien race prevent the death of the universe? This is a very deep question and from a formal scientific basis we indeed do not have adequate information to formulate an answer. However the Hindu philosophy (and some others) instructs us that there are various 'levels' of creation that encompass the respective level below. The Hindu philosophy ... (more)	—	almost 6 years ago
Answer	—	A: How to go out for a walk in microgravity? Your question related to staying down in microgravity. Without a gravity field generator or something the answer is to increase the mass. While this is not ideal from an inertia point of view it will keep you closer to the planet. You could have concrete boots, a walking frame or jump into a fluid... (more)	—	about 6 years ago
Answer	—	A: How could mankind of ancient times cause significant climate change? Redirecting rivers may be some help by causing desertification and changes in local rainfall. Directing them into blind valleys may cause salt pans that reflect sunlight locally which may not be desired. The best way to melt ice is to cover it with something that will absorb more sunlight. A black... (more)	—	over 6 years ago
Answer	—	A: How to stop a massive canal system from silting up? Have the very durable material canal meander slightly and have narrow side channels all along the length at the inside of the meander curves where the silt will collect. If the channel is 30m deep and erosion proof and the median water flow requires only 15 meters depth then the water will cut a cha... (more)	—	over 6 years ago
Answer	—	A: What abilities might each member of a 4-person planetary recon craft have? I like Sepratrixes answer as it interprets the old style question framework by OP. As a start the first thing would have been to research what the Mars colonist teams have planned and then make allowance for the fact that that is a long term exploration. Compare this with the moon landing teams and ... (more)	—	over 7 years ago
Answer	—	A: What is the least expensive way to annihilate humanity? Design a self replicating robot that consumes natural resources. Picture a machine that can convert wood and straw into plastic and carbon nanotube conductors and piezoelectric actuators and thin film printed semiconductors and all sorts of other good stuff using just wood and straw as raw materia...

Answer	—	A: Where in Europe can I detonate 100 kt (non-nuclear) not to harm anyone? A derelict oil rig is what you are looking for. At least one has burnt up and left something standing that may still be there. There may be sea forts in the north sea that are far enough away and if you put it higher you get less tidal wave. The barge proposal is still most likely to succeed. A n... (more)	—	about 9 years ago
