    Is this a notable claim? You should provide sources to prove that this claim is notable. – Arcanist Lupus Dec 18 '18 at 6:35

    Why is this tagged as "life-expectancy"? Anyway, OP originally posted this on Space.SE, and the comments there include a Wikipedia page on the Black Knight conspiracy theory, so I'd say this is notable enough. – F1Krazy Dec 18 '18 at 6:41

    @F1Krazy: Using the Wikipedia page as a notability reference makes the question rather silly, because it answers the question and because there is nothing there to suggest that this is still a serious contention in 2018. – Oddthinking Dec 18 '18 at 6:52

    Welcome to Skeptics! We have a rule that only widely-held beliefs are in scope for this site (or at least, claims made by notable people and organisations that are widely seen). Please provide some references to places where this claim is being made. – Oddthinking Dec 18 '18 at 6:52
  • @Oddthinking - google.com/search?q=black+knight+satellite shows tons of links, so notability is not really an issue. (I agree that Wiki page may answer the question, but that's separate from notability) – user5341 Dec 20 '18 at 3:20
