[Sherlock Holmes] Can there be a mystery that can only be solved by knowing about heliocentricism?

Holmes and Watson famously had the following exchange:
> That any civilized human being in this nineteenth century should not be aware that the earth travelled round the sun appeared to be to me such an extraordinary fact that I could hardly realize it.
> 
> “You appear to be astonished,” he said, smiling at my expression of surprise. “Now that I do know it I shall do my best to forget it.”
> 
> “To forget it!”
> 
> “You see,” he explained, “I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose…”
> 
> “But the Solar System!” I protested.
> 
> “What the deuce is it to me?” he interrupted impatiently; “you say that we go round the sun. If we went round the moon it would not make a pennyworth of difference to me or to my work.”

That said, *could* there ever be a mystery that Sherlock would not be able to solve if he didn't know this fact? Are there any that he didn't solve because he forgot something that he thought something too unimportant?

I think this comes up in this decade's TV show (set in the 21st century). He detects that a painting is a forgery because of random astronomy trivia it took him a while to dredge up. It makes him really angry because they had the heliocentrism discussion earlier that week.
