Physicist Proposes Alternative to Black Holes

[KG3]

This article caught my eye.

"What do you get when you cross two hypothetical alternatives to black holes? A self-consistent semiclassical relativistic star, according to Raúl Carballo-Rubio (International School for Advanced Studies, Trieste, Italy) whose recently published results in the February 6th Physical Review Letters describe a new mathematical model for the fate of massive stars..."

Repulsive Gravity

"Now, Carballo-Rubio adds an extra force into the mix: quantum fluctuations. Quantum mechanics has shown that virtual particles spontaneously pop into and out of existence — the effects can be measured best in a vacuum, but these fluctuations can happen anywhere in spacetime. These particles can be thought of as fluctuations of positive and negative energy that under normal conditions would cancel out. But the extreme gravity of compact objects breaks this balance, effectively generating negative energy. This negative energy creates a repulsive gravitational force."

To this total layman, this sounds a bit like Hawking radiation.

Yah, I know!  When I read "repulsive gravity" I just wonder if this is for real.  The article says that the theory should be testable with the next generation of gravity wave detectors. 

Is repulsive gravity the same as antigravity?
