The photo above is the closest humanity has ever come to creating Medusa. If you were to look at this, you would die instantly.Friendly reminder that this blob of core material was so hot and dense, it melted/burned through three floors of the building before coming to rest in the lowest basement.
The image is of a reactor core lava formation in the basement of the Chernobyl nuclear plant. It’s called the Elephant’s Foot and weighs hundreds of tons, but is only a couple meters across.
Oh, and regarding the Medusa thing, this picture was taken through a mirror around the corner of the hallway. Because the wheeled camera they sent up to take pictures of it was destroyed by the radiation. The Elephant’s Foot is almost as if it is a living creature.
And there’s now a unique species of black mold that feeds off the gamma radiation it produces.
