Wait, so my life may not have disappeared down a black hole after all?
There is a chance for it to emerge and bloom like the career of David Hasselhoff?
It’s charming when a phrase enters the language and we think we all know what it means. In the case of “black hole,” we think of an infinity of black nothingness that swallows everything that slips into it.
But now, in a new paper called “Information Preservation and Weather Forecasting for Black Holes,” Stephen Hawking has cast the cat among the black, holey pigeons and caused a scattering of incomprehension.
His precise words were: “The absence of event horizons mean that there are no black holes — in the sense of regimes from which light can’t escape to infinity.”
It seems clear. There are no forever and ever holes of blackness. There is always the chance that light might emerge.
Hawking continued, however: “There are however apparent horizons which persist for a period of time. This suggests that black holes should be redefined as metastable bound states of the gravitational field.”
So there are black holes. It’s just that we should redefine them a touch. So what’s this apparent horizon?
