A new Stephen Hawking presentation about black holes

I don't understand what's new about these theories. Both the holographic principle and Hawking radiation have been known for years, decades even. If there's something about those theories the article doesn't explain what it is exactly.

I don&#x27;t know if there&#x27;s something new in there, but Leonard Susskind wrote a book in 2008 exactly on that matter - &quot;The Black Hole War&quot; [0]. He describes his &quot;battle&quot; with Hawking on whether the information is lost in the black hole, and Susskind is the one who&#x27;s against information disappearing.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_Black_Hole_War" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_Black_Hole_War</a>

Wait, hasn&#x27;t this holographic theory been arround for years? What&#x27;s new?

I don&#x27;t know a thing about black holes, but every time I see him I&#x27;m impressed that someone with such severe disabilities is still able to accomplish so much.

Does physics have some &quot;conservation of information&quot; laws that I missed the memo about? Can anyone recommend some introductory reading about this?

Something that is hard to mention but is worth knowing is that Hawking is not at the leading edge of his field.

It seems that matter usually doesn&#x27;t fall through the event horizon: due to time dilution it will take infinite time for matter to reach the horizon from our point of view.<p>That&#x27;s what I&#x27;ve got on Physics stack exchange. There&#x27;s those collapsars that look exactly like black holes but are made of matter around the event horizon, infinitely falling in.<p>Is this right, wrong, or irrelevant?

A video of Hawking&#x27;s presentation is available at <a href="https:&#x2F;&#x2F;www.kth.se&#x2F;en&#x2F;aktuellt&#x2F;nyheter&#x2F;hawking-offers-new-solution-to-black-hole-mystery-1.586546" rel="nofollow">https:&#x2F;&#x2F;www.kth.se&#x2F;en&#x2F;aktuellt&#x2F;nyheter&#x2F;hawking-offers-new-so...</a>

How come quantum indeterminacy doesn&#x27;t preclude information preservation?

&quot;You wouldn&#x27;t technically lose any information if you kept all of the ashes in one place, but you&#x27;d have a hard time looking up the capital of Minnesota.&quot;
