The Big Bang singularity is indistinguishable from an Act of Creation

June 11, 2017

Most modern physicists and cosmologists who believe (note – believe) in the Big Bang theory of the Universe believe implicitly in an Act of Creation (the Big Bang Singularity) but then usually ignore the question of how and why the singularity occurred. They focus on the Act of Creation and after but do not address the cause of the singularity or a Creator. Religions of all kinds have their own Creation myths but focus on the presumed Creator much more than on the Act(s) of Creation.

(My own belief is that all religions live in the space of ignorance and physics – like all religions – is ultimately dependent upon Magic).

Stephen Hawking describes the Big Bang Singularity thus:

The situation was different, however, when it was realised that the universe is not static, but expanding. Galaxies are moving steadily apart from each other. This means that they were closer together in the past. One can plot the separation of two galaxies, as a function of time. If there were no acceleration due to gravity, the graph would be a straight line. It would go down to zero separation, about twenty billion years ago. One would expect gravity, to cause the galaxies to accelerate towards each other. This will mean that the graph of the separation of two galaxies will bend downwards, below the straight line. So the time of zero separation, would have been less than twenty billion years ago. 

At this time, the Big Bang, all the matter in the universe, would have been on top of itself. The density would have been infinite. It would have been what is called, a singularity. At a singularity, all the laws of physics would have broken down. This means that the state of the universe, after the Big Bang, will not depend on anything that may have happened before, because the deterministic laws that govern the universe will break down in the Big Bang. The universe will evolve from the Big Bang, completely independently of what it was like before. Even the amount of matter in the universe, can be different to what it was before the Big Bang, as the Law of Conservation of Matter, will break down at the Big Bang. 

Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang. Events before the Big Bang, are simply not defined, because there’s no way one could measure what happened at them. This kind of beginning to the universe, and of time itself, is very different to the beginnings that had been considered earlier. These had to be imposed on the universe by some external agency.

He goes on, however, to make an unsupportable conclusion.

There is no dynamical reason why the motion of bodies in the solar system can not be extrapolated back in time, far beyond four thousand and four BC, the date for the creation of the universe, according to the book of Genesis. Thus it would require the direct intervention of God, if the universe began at that date. By contrast, the Big Bang is a beginning that is required by the dynamical laws that govern the universe. It is therefore intrinsic to the universe, and is not imposed on it from outside. 

Genesis requires time to begin at 4004 BC and the Big Bang is no different in concept. It too defines the start of time and takes us back to 13.8 (give or take a few) billion years ago. Time is not defined before the Act of Creation – whether by the Big Bang or by the hand of God.

(Note that if the flow of time has a beginning then the concept of a before or an after has no meaning before the beginning of time.  The magical speed of an inconstant time).

Hawking concludes:

The conclusion of this lecture is that the universe has not existed forever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down. Nevertheless, the way the universe began would have been determined by the laws of physics, if the universe satisfied the no boundary condition. This says that in the imaginary time direction, space-time is finite in extent, but doesn’t have any boundary or edge. The predictions of the no boundary proposal seem to agree with observation. The no boundary hypothesis also predicts that the universe will eventually collapse again. However, the contracting phase, will not have the opposite arrow of time, to the expanding phase. So we will keep on getting older, and we won’t return to our youth. Because time is not going to go backwards, I think I better stop now. 

It seems to me that he contradicts himself when he says “The beginning of real time, would have been a singularity, at which the laws of physics would have broken down. Nevertheless, the way the universe began would have been determined by the laws of physics, …..” 

The Big Bang singularity where the laws of physics do not apply is just another Act of Creation. If the laws of physics do not apply at the singularity then, which laws or whose laws do? Or do the laws of physics change? Do they vary in different universes such as that which may have existed before the Big Bang?

Even a singularity must follow some laws. It is disingenuous of physicists and cosmologists to claim that the laws of physics break down at the Big Bang singularity and not address which or whose laws apply at the singularity. If, however, no laws apply at the singularity then the Singularity is Omnipotent (or Magic or God or whatever other label suits you).

I prefer to think it’s Magic.

The fundamentals of physics are just magic.
