This is possibly the most misleading headline I have ever seen anywhere. It's not the headline of the linked article, it doesn't resemble the headline in the linked article, and it makes a ridiculous claim about a central issue in modern physics.

The linked article discusses a hypothesis that is contradicted by much observational evidence for the existence of black holes. The hypothesis deserves a hearing, but it's merely someone's pet theory that has no evidentiary support (a requirement for something to be called science).

To extrapolate this hypothesis, this speculation, to the claim that quantum and relativity theories have been brought "into harmony" is embarrassingly ignorant of the most basic physical principles.
