The Universe is impossible, and quantum foam is a way of making it happen while ignoring this fact.

The control systems were trying to shove the molehole back down into the quantum foam where it belonged, and failing.

Geons, black holes and quantum foam: A life in physics.

And don't even get me started on quantum foam and superpositions.

Smoke pours from the computer, and space and time themselves dissolve into a quantum "foam."

"I am confidently making a bet that quantum foam will be detected."

It went spiraling off into the quantum foam somewhere.

"And what's the point of this quantum foam, Kevin?"

Thus experimental evidence so far has given a range of values in which scientists can test for quantum foam.
