Polchinski's paradox was what if you sent a billiard ball through the wormhole into the past such that it collides with its previous self, deflecting it so that it never enters the wormhole in the first place. [5][6] Die Firewall wurde ursprünglich als Lösung von Verschränkungs-Paradoxa der Hawking-Strahlung eingeführt,[7] wird aber (da dem Äquivalenzprinzip widersprechend) auch selbst als „Paradoxon“ aufgefasst und führte zu einem wissenschaftlichen Diskurs, in dessen Verlauf unter anderem Stephen Hawking 2014 vom Konzept eines strikten Ereignishorizonts in der ART abrückte.
