“The only rational solution, in terms of conceptual coherence (the only thing we can judge here), to give a realistic meaning to the notion of "imaginary time" is to abandon the notion of time. We would then have to opt for the idea of atemporal time. A reformulation of Hawking's theory would be to say that below the Planck Wall, we arrive at an atemporal universe. But this hypothesis itself seems difficult to sustain. Firstly, because an atemporal physical reality would have to be absolutely immutable, unchanging, and therefore absolutely cold. The problem is that the initial physical state of the universe, however quantum, is anything but cold. On the contrary, it is extremely hot. But it gets worse: such a state of the universe, if it is atemporal, cannot be in a temporal relationship with the temporal universe, so it cannot exist "before" the Big Bang, but must coexist with it eternally. This would presuppose that this original atemporal universe continues to exist today in this atemporal state, which is contradictory to the hypothesis, since it is supposed to have "transformed" itself into our universe. What's more, since this atemporal state never began, the universe should have sprung from it an infinite time ago (a temporal reflection of timelessness), which is clearly not the case, since our universe has a finite past. Surely, in place of the = 0 singularity of standard theory, we can conceive of an immutable, simple, atemporal, universe-producing and truly subsistent reality. But as this cannot be a physical reality, we are simply describing a non-physical, timeless, immaterial, all-powerful reality with a free will. And we call it "God".”
