Above is the Kola Superdeep Borehole, the deepest hole ever dug by man (without hand tools.) Astoundingly, the hole reaches 7.6 miles which is deeper then the Mariana Trench and Mt. Everest is tall! It is located in Murmansk, Russia.
Here's the Kimberley Big Hole! It's the biggest hand dug hole on earth. (It was dug using pick axes and shovels). Located in Kimberley, South Africa
Here's the Sarlac Pit!
It is a carnivorous pit... it slowly digests its prey after 1000 years.
This is TON 618. The biggest BLACK HOLE we have found SO FAR... (Ominous tone).
