Our Black Hole predicament

 



I never liked black holes. I like the idea of black holes evaporating even less. So first they destroy everything, including "information" itself, and then they just disappear? Wtf...

Can anyone plz debunk their very existence???

Meanwhile, I suppose we will have to settle for the lesser evil: Sabine Hossenfelder´s explanation for why "the Black Hole Information Problem" is unsolvable. Not in principle, but for all practical purposes, since it would presumably take thousands of years for humanity to make the required empirical observations to prove or disprove some particular theory about the problematique.

And this is Hossenfelder´s main point: sure, the Black Hole Information Problem can be solved mathematically ("the math works"), but this doesn´t mean much without empirical backing from the real world. Yet, many scientists confuse what "works" mathematically with what´s actually the case IRL. And in this case, many different mathematical "solutions" apparently "work", so how do you tell the good from the bad (or the really ugly) based on equations alone? 

Which somehow confirms my suspicions about mathematics, while making its ontological status even more opaque. Perhaps even more opaque than black holes...

  1. Jag har inget emot svarta hål, däremot retar jag mig på att Hawkings teori om att svarta hål sänder ut en mycket mycket mycket svag strålning som gör att det om ett stort antal eoner kommer att upplösas kallas för en upptäckt.

  2. Just det. Den tyska kvantfysikern som håller i kanalen verkar acceptera Hawkins upptäckt, men menar att de problem den leder till är olösliga. Annars är ju hennes kritik av Matematiken med stort M väldigt intressant...

    Hennes syn på matematik kanske är lite annorlunda vad jag trodde, men den är ändå intressant. Se länk ovan.
