Sorry to disappoint you Dave. But a black hole the size of Manhattan anywhere near our little corner of the galaxy would be devastating. If a black hole that size were on Earth ...anywhere... Let alone Antarctica ... The very moment it appeared... You and everyone one else, and everyrhing else...and the entirety of the Earth and its contents would instantaneously be squashed and compressed until there was virtually no space between the atoms...and all of it and us included ...reduced to about the size of a pea...of compressed matter...most likely smaller.. Soooo... No . No black hole in the Antarctic . Bad enough it is melting at a rate not expected or anticipated .
