Πράγματι για τον Stephen Hawking έχουν γραφτεί αντικρουόμενες απόψεις για το θέμα.Παραθέτω άποψη ενός άλλου μεγάλου θεωρητικού φυσικού Bernard d'Espagnat καθαρότατη και ενδιαφέρουσα."What quantum mechanics tells us, I believe, is surprising to say the least. It tells us that the basic components of objects – the particles, electrons, quarks etc. – cannot be thought of as "self-existent". The reality that they, and hence all objects, are components of is merely "empirical reality"." "This reality is something that, while not a purely mind-made construct as radical idealism would have it, can be but, the picture our mind forces us to form of ... OF WHAT ? The only answer I am able to provide is that underlying this empirical reality is a mysterious, non-conceptualisable "ultimate reality", not embedded in space and (presumably) not in time either." Bernard d'Espagnat (22 August 1921 – 1 August 2015) was a French theoretical physicist, philosopher of science, and author, best known for his work on the nature of reality.
