Question	—	Can free-space holograms exist? Holograms are a real thing. But what science-fiction TV shows and movies call holograms are something different entirely. From a classical geometric optics standpoint, in order to create the illusion of an object there must be some sort of light-emitting or light-modulating surface along the line f...

Question	—	Traffic in Space (a traffic controller for low earth orbit) In a future where space travel is common, how would access to space be regulated? From what I know, currently the International Telecommunication Union (ITU) assigns slots for geostationary satellites (since the range of geostationary is essentially one-dimensional and otherwise interference would c...
