I think you mean "below". Or, is there a mountain of Dark Matter 172 meters above the floor of Death Valley? Did you see it? Your are all about Dark Matter, right? Were you standing on the Dark Matter to make your measurement? Could you tell us how you do that? It's almost like there is water in Death Valley :-). BTW: there are other places hotter. Read the book "The Uninhabitable Earth" by Wallace-Wells. Good book.

Opposition errors are common in human language which linguistics notes that word opposites have nearly exactly the same meaning except for one bit of information, the 'not'. It's how we can lie a lot and so easily if we don't care to tell the truth.
