Portable Hole in a Bag of Holding

It is generally accepted that placing a Portable Hole inside a Bag of Holding would result in a catastrophic explosion. This is because the two magical items have opposing extradimensional spaces that cannot coexist. When the two spaces come into contact, they would create a rift in the fabric of reality, causing a massive explosion that would likely destroy everything in the vicinity. This is often referred to as the "Bag of Holding Bomb" or the "Portable Hole Catastrophe."
