What the Hacker News discussion says — and what it does not
Discussion focus
Across the sampled HN recommendations, people specifically point to Great explanation of solar gravitational lens imaging. and Fleet of lightsails with optics imaging exoplanets..
A recorded perspective
The recorded HN source is “is a great great video on the subject. I can't recommend enough” — a useful perspective from augusto-moura in 2020-09, rather than a claim that every Hacker News reader agrees.
Evidence boundary
Alongside recommendations, the export retains a reference mention from Diederich (2020-07): “A recent video talking about what it could take to get high resolution imagery of exoplanets.” This is context, not proof; use the linked discussion to inspect the original thread.
