An Italian man found out the hard way that a very realistic-looking painting of a black hole was, in fact, an actual black hole.
The man tumbled 8 feet down into the art installation at a Portuguese museum.
The piece, called Descent Into Limbo, features a hole, covered on all sides with extremely black paint, to give the illusion that it has no depth at all.
The museum says there are a number of warnings, telling visitors the hole is real and not to step on it, but there are no ropes.
Fortunately, the man who tested the art out is going to be OK.
He's now at home recovering from a back injury.
