Is is possible to do the same in visible light? Is only the CPU power the limiting factor or is there some physical limit?
Would it be possible to use similar technology to launch 2 space-based telescopes and put one on the far side of the Sun with respect to the other to get and effective mirror size of about 2 AU? Is only money the limiting factor to do something like that or is there some physical limit? Or maybe there simply is no point to push the diffraction limit so far with a 2 AU mirror?
