New Theory: Survivable Black Holes & “Infinite Futures”

[Escher]

A new study from Berkley University theorises not only that humans could survive going into a black hole, but that their past could be erased, giving way to “infinite futures”.

Physicist Peter Hintz argues that if a human traveller entered a “relatively benign” black hole, they might be able to shed the natural laws of physics - and survive.

It's interesting stuff (the full paper is here) but extremely conjectural. The scattering of phrases like:

...suggests
 that the metric will have similar extendibility properties
 as the scalar field. It is then tempting to conjecture, as
 was done before in Refs. [6, 23, 24]: if there exists a parameter
 range for which β > 1/2 then the corresponding
 (cosmological) BH spacetimes should be extendible beyond

the Cauchy horizon with metric in H¹
 .
Even more strikingly,
 one may be able to realize some of the previous
 extensions as weak solutions of the Einstein equations.
 
This would correspond to a severe failure of SCC, in the
 presence of a positive cosmological constant!

indicates an utter lack of actual evidence and that the authors are engaging in speculation.

SCC, BTW, is the Strong variant of Penrose's Cosmic Censorship Hypothesis
(wiki) and it's disproval would be immensely changing to current models of physics, indicating that events cannot be reliably predicted from starting conditions. Not necessarily a bad thing for time travel...
