One possibly overlooked problem with this is that alien races / robots may be able to see this sun shield from a vast distance. They will know that we are primitive people who have not yet figured out quantum dot solar and who still die from cancer.
No wait... if we put it up then we'll still have 50 or so years before this information reaches such alien planet. So we should be OK if we can figure those things out soon.
Sorry for the alarm.
- pavel_lishin 11y agoGiven our current telescope technology, and assuming that others in the galaxy have the same thing, they could probably easily figure out that we're here - in the same amount of time. (Limit of light speed, and all that.) And unless they've got FTL, it'll take awhile for them to do anything about it, anyway.
