On slashdot, in the context of a discussion on dark matter, I stumbled over a poster saying there were "Galaxy-sized masses causing gravitational lensing where there's no galaxy".

Never heard about that one before. The replies don't question it, but is there any source for that?
(Slashdot has made "Anonymous coward" postings a pain in the ass, so I won't ask there.)
