Message: <blockquote data-quote="Umbran" data-source="post: 6687698" data-attributes="member: 177">The basic notion that black holes must deal with entropy (and thus information) goes back to the 1970s.  I think the new bit here may be in some of the description of details, not the overall notion.That does not follow quite so much, in that black holes are not known for interacting much, except to draw you in and swallow you <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile    :)"  data-smilie="1"data-shortname=":)" />  A bit of the information from the black hole is carried away with every bit of Hawking radiation coming off of it.  It is not lost, but comes off in dribs and drabs, bits not associated in any way meaningful to a human.  As the article puts it, it is kind of like burning an encyclopedia - if you keep the ash and smoke, you don't actually lose anything, but good luck looking anything up. <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile    :)"  data-smilie="1"data-shortname=":)" />There are maths that, with proper interpretation, say that upon entering a black hole, you can gain access to spaces that sure look like other universes.  But that's not "another universe created at the event horizon".  If I recall correctly, access to the other spaces is found near the singularity.  In most senses, the event horizon isn't all that special a point - physics breaks down at the middle of the thing, not at the edge.</blockquote>
