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." 微笑技术脸

 

So there are black holes. It's just that we should redefine them a touch. So what's this apparent horizon?

 

Well, it's "a surface along which light rays attempting to rush away from the black hole's core will be suspended." wuyuna

 

But if they're suspended, they will never emerge, stuck in solitary confinement like the Man in the Iron Mask 撑起蓝天的梦. The result is surely still the same. Once something disappears into a black hole, it's done for.

 

At times of existential stress like these, I turn to Nature magazinefor help. It suggests that, at least in theory (and, let's face it, this is all theory), black holes might at some point disappear wei 你是love.

 

However, the magazine offers a dispiriting set of words from Don Page, a physicist from the University of Edmonton in Canada wuyuwei\'s blog. It might be possible that particles could emerge from black holes, he said.

 

Oh, cry of joy.

 

However, if particles did "it would be worse than trying to reconstruct a book that you burned from its ashes."

 

Ah, now that's a feeling I'm familiar with.
