CHAPTER 8 THE ORIGIN AND FATE OF THE UNIVERSE

Einstein’s general theory of relativity, on its own, predictedthat space-time began at the big bang singularity and wouldcome to an end either at the big crunch1 singularity (if thewhole universe recollapsed), or at a singularity inside a blackhole (if a local region, such as a star, were to collapse2). Anymatter that fell into the hole would be destroyed at thesingularity, and only the gravitational effect of its mass wouldcontinue to be felt outside. On the other hand, when quantumeffects were taken into account, it seemed that the mass orenergy of the matter would eventually be returned to the restof the universe, and that the black hole, along with anysingularity inside it, would evaporate away and finally disappear.
Could quantum mechanics have an equally dramatic effect onthe big bang and big crunch singularities? What really happensduring the very early or late stages of the universe, whengravitational fields are so strong that quantum effects cannot beignored? Does the universe in fact have a beginning or anend? And if so, what are they like?
Throughout the 1970s I had been mainly studying blackholes, but in 1981 my interest in questions about the origin andfate of the universe was reawakened when I attended aconference on cosmology organized by the Jesuits in theVatican. The Catholic Church had made a bad mistake withGalileo when it tried to lay down the law on a question ofscience, declaring that the sun went round the earth. Now,centuries later, it had decided3 to invite a number of experts toadvise it on cosmology. At the end of the conference theparticipants were granted an audience with the Pope. He toldus that it was all right to study the evolution of the universeafter the big bang, but we should not inquire into the big bangitself because that was the moment of Creation and thereforethe work of God. I was glad then that he did not know thesubject of the talk I had just given at the conference - thepossibility that space-time was finite but had no boundary,which means that it had no beginning, no moment of Creation.
I had no desire to share the fate of Galileo, with whom I feela strong sense of identity, partly because of the coincidence ofhaving been born exactly 300 years after his death!
In order to explain the ideas that I and other people havehad about how quantum mechanics may affect the origin andfate of the universe, it is necessary first to understand thegenerally accepted history of the universe, according to what isknown as the “hot big bang model.” This assumes that theuniverse is described by a Friedmann model, right back to thebig bang. In such models one finds that as the universeexpands, any matter or radiation in it gets cooler. (When theuniverse doubles in size, its temperature falls by half.) Sincetemperature is simply a measure of the average energy - orspeed - of the particles, this cooling of the universe would havea major effect on the matter in it. At very high temperatures,particles would be moving around so fast that they couldescape any attraction toward each other due to nuclear orelectromagnetic forces, but as they cooled off one would expectparticles that attract each other to start to
