- chaps 3y agoThanks for sharing! Some interesting things -- "And one would like to launch hundreds of spacecraft (at least) in different directions so that some would come within dozens of AU of Planet 9, rather than hundreds of AU." Their example of a neat-but-good-luck project could actually achieve the goal is [1]. The spec requires ground lasers that's powered by a 1GW nuclear power plant for propulsion. And, "According to The Economist, at least a dozen off-the-shelf technologies will need to improve by orders of magnitude."

- kristianp 3y agoWould gravitational lensing be usable to detect one of these tiny black holes?
- codethief 3y agoI don't think so. The black holes are, by assumption, tiny and only light passing by very very closely would experience significant lensing. Farther away, the lensing would be the same as near any other planet.
