“Even today, there persists… a feeling that the creation of the Universe out of nothing must violate some basic conservation law that stops one from getting something for nothing. Nevertheless, there is actually no evidence that the Universe as a whole possesses a non-zero value of any such conserved quantity. The total mass-energy of all the constituents of a finite Universe appears to be always equal in magnitude but opposite in sign to the total gravitational potential energies of those particles. …Similarly, there is no evidence that the Universe possesses any overall net rotation or electric charge.”

“It turns out that the energy of a gravitational field—any gravitational field—is negative. During inflation, as the universe gets bigger and bigger and more and more matter is created, the total energy of matter goes upward by an enormous amount. Meanwhile, however, the energy of gravity becomes more and more negative. The negative gravitational energy cancels the energy in matter, so the total energy of the system remains whatever it was when inflation started—presumably something very small. …This capability for producing matter in the universe is one crucial difference between the inflationary model and the previous model.”

“The existence of matter and energy in the universe did not require the violation of energy conservation at the assumed creation. In fact, the data strongly support the hypothesis that no such miracle occurred. If we regard such a miracle as predicted by the creator hypothesis, then the prediction is not confirmed.”

“The Law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it.”

“In 1963, when I completed my PhD, it was mostly on the steady-state theory using mathematical formulations to describe creation of matter. People always argued that you cannot have matter coming out of nothing, what would happen to the law of conservation of matter. It is a normal criticism of the steady-state theory. One could answer it either in one sentence by saying what is the big-bang theory where the entire universe came out of nothing, so you are violating the law of conservation of matter and energy in a big way. But that would be to point out the weakness of the other theories and not answering your own theory.”

“The universe would have expanded in a smooth way from a single point. As it expanded, it would have borrowed energy from the gravitational field, to create matter. As any economist could have predicted, the result of all that borrowing, was inflation. The universe expanded and borrowed at an ever-increasing rate. Fortunately, the debt of gravitational energy will not have to be repaid until the end of the universe.”

“So it was better to think of formulations which could explain the creation of matter without violating the law of conservation of matter…For that we used what is called as negative energy, which at that time was considered unrealistic. There was a good example of negative energy, mainly Newtonian gravity. Newtonian gravity is a negative energy system because gravitational potential energy is negative and we i. e, Fred Hoyle and me, worked out a fairly consistent method of describing this whole thing. Today what people call phantom fields, an idea which is catching up with people trying to explain some problems of the big-bang, these phantom fields are what we had proposed way back in the 1960’s.”

“Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.”

The Grand Design (2010)

“A precept claiming infallibility should certainly possess the universality of the law of gravitation and the perfection of the arithmetical table. If it fails to possess these undeviating qualities, its imperfection is self-evident and its value either greatly diminished or useless.”

“There was always something left: a vacuum energy that permeated every fibre of the Universe.”

John D. Barrow (1952–2020) British scientist

Context: The quantum revolution showed us why the old picture of a vacuum as an empty box was untenable.... Gradually, this exotic new picture of quantum nothingness succumbed to experimental exploration... in the form of vacuum tubes, light bulbs and X-rays. Now the 'empty' space itself started to be probed.... There was always something left: a vacuum energy that permeated every fibre of the Universe.

“In both the solutions A and B the curvature is positive, in both three-dimensional space is finite: the universe has a definite size, we can speak of its radius, and, in the case A, of its total mass. In the case A… the density is proportional to the curvature… Thus, if we wish to have a finite density in a static universe, we must have a finite positive curvature.”
