Let us explain the above with examples. Spontaneous electromagnetic radiation by atoms or spontaneous fission of heavy atomic nuclei occurs due to the instability of their energy (or other) state. The time of this event cannot be precisely determined, but is described probabilistically, according to the corresponding distribution function.
However, can we talk about the spontaneous emergence of the laws of physics (as Krauss says)? Of course not. For spontaneous occurrence of a photon, at least a hydrogen atom is needed. If the atoms (matter) themselves do not exist, then there will be no phenomenon of spontaneity, no wave functions of electrons, etc. The same can be said about the vacuum, which has energy and is capable of producing particles. Krauss wrote in his book A Universe from Nothing:
“The existence of energy in empty space-the discovery that rocked our cosmological universe and the idea that forms the bedrock of inflation-only reinforces something about the quantum world that was already well established in the context of the kinds of laboratory experiments I have already described. Empty space is complicated. It is a boiling brew of virtual particles that pop in and out of existence in a time so short we cannot see them directly.” [20]
But this means that the “empty space” that cosmologists study is not “nothing” at all, but a physical (material) object under the conditions of space-time and the existing laws of physics.
Cosmologists talk about quantum fluctuations of the physical vacuum, about the spontaneous emergence of particle-antiparticle pairs in very strong electric fields from “nothing”, about fluctuations of the scalar field (which allegedly gave rise to the universe). However, all these examples are taken from the material world with already existing physical laws. Thus, by “nothing” cosmologists mean, as it were, a special “pra-matter” that existed outside space and time. All theories that talk about the possibility of the emergence of the universe from “nothing” require the preliminary existence of the laws of physics and a special “nothing” that has the potential to give birth to quantum particles.
However, it begs the question: how did the laws of physics themselves emerge if there was nothing material yet, and why the original “nothing” could have any potential. Krauss quotes Richard Feynman in Preface of A Universe from Nothing: “The laws of physics could be like an infinitely layered onion, with new laws becoming operational as we probe new scales.” In addition, a little earlier, he recalled about the famous “story of an expert giving a lecture on the origins of the universe (sometimes identified as Bertrand Russell and sometimes William James), who is challenged by a woman who believes that the world is held up by a gigantic turtle, who is then held up by another turtle, and then another . . . with further turtles ‘all the way down!’” [21]
In fact, there are not only turtles, but a whole zoo: an elephant, a boa constrictor, a tiger, wild boars and a whale that swims in a bottomless and endless ocean. Krauss and those to whom he refers are arguing with representatives of the Abrahamic religions, in whose cosmogony there is nothing of the kind. But for the sake of argument, wanting to ridicule religion, Krauss mentions this “zoo” of Hinduism. However, he does not realize that he is ridicule of himself.
Only someone who is very stupid will take the ancient metaphor literally. The opposition of ancient myths and scientific cosmogony is already a myth in itself, a method of demagoguery.
