Two wild thoughts:
Could a technique evolve someday where you don't even need the mirror but just the sensor and the collected data is then processed as if it was focused by a mirror?
Could a liquid be developed based on a molecule with near perfect reflectivity, a few liters of it is taken into space and then pulled out like a soap bubble at molecule-level thinness?
- icegreentea2 4y agoFor your first thought - if we could capture the phase information of the incoming light, then yes. We actually already do this for radio waves- you may have heard of synthetic aperature radar, or AESA/PESA radars in a military context, or the event horizon telescope network (the thing that got us the 'first picture of a blackhole'). For your second thought - as literally described, such a thing would probably be badly impacted by solar wind.
