Comment Comment by throw0101a Tom Scott did a video on the ELT about a month ago:* https://www.youtube.com/watch?v=QqRREz0iBesMost of the video is an explanation of (a) why ground-based telescopes are still useful, and (b) why ganging up multiple telescopes (to create a large 'virtual' area) only goes so far, and then he gets into the ELT in part three of the video.It's big. The scale is remarkable. parent throw0101a 3 years ago
