makes damn little sense.
Hawking’s proposal is an attempt to answer a problem that has tormented
physicists about what happens to things when they go beyond the event horizon, where even light can’t get back. The information about the
object has to be preserved, scientists believe, even if the thing itself
is swallowed up — and that paradox has puzzled scientists for decades.
My problem with that: The information about the
object has to be preserved, scientists believe,
Why? Yes, I know: "Quantum mechanics, things work differently on that level!" Which still leaves me in the dark. Why would the 'information about the object' need to be preserved instead of simply going into the hole with the physical?
Now Hawking has proposed that the information is stored on the boundary,
at the event horizon. That means that it never makes its way into the
black hole, and so never needs to make its way out again either.
Stored? How and why? Is this something required by current theory, so they're trying to save it, or what?
Ah, another article on it, which contains this:
...These things cannot be lost, according to the way we think the universe
works, and physicists generally believe that they aren't really lost. But where does the information go when the black hole that's absorbed it goes kaput?
It's brainy stuff, but without an explanation for the apparent paradox,
some of the most basic laws we think exist in the universe are at stake.
At a public lecture in Stockholm on Monday, Hawking implied that our concept of time itself could fall apart if black holes proved to be exempt from such laws.
Ah, there we go.
The problem there is 'our concept of time' and 'such laws' are just that: OUR concept, and 'laws' here actually means 'How we understand things to work, based on what we've currently found. Or in some cases, we've played with numbers and said Eureka!" And a lot of people really don't like the idea that said understanding is either wrong, or incomplete enough to make real problems. Or so it seems to me.
Yes, I'm quite away that my level of knowledge of this is low, and I'm probably missing some "This is why you're wrong, you clod". Still.
