Is the Vacuum Polarization Creating an Event Horizon?

It's possible that the background, which has a larger vacuum polarization than usual, disrupts the formation of the event horizon. 's not able to say whetheror not that happens. But even though ther there may be no van horizon forming in the scenerio, he still drives like a hawking like flux of plankean radiation,. So you still end up with some sort of radiation. This is from the vacuum polarization that you're creating.
