He was awarded the 2017 Fundamental Physics Prize in recognition of his contributions to theoretical physics. 2007 erhielt er den Dannie-Heineman-Preis für mathematische Physik und 2008 die Dirac-Medaille (ICTP). There is a general philosophical consensus on the arrow of time (see Reichenbach). As in physics, paradoxes in biology really are just unsolved puzzles. Phys. Biologist Richard Peto noticed in the 1970s that mice had a much higher rate of cancer than humans do, which doesn't make any sense.

[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.
