“In fact, if you have a very large volume of mass at constant density, then it is guaranteed to become a black hole if the volume is large enough — no matter how small the density! [13] This means that if we had a large volume of soft cotton wool, with a uniformly low density, it would collapse to form a black hole as long as the volume was large enough.”

“We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance.”

“So the vacuum energy can result in negative pressure. And this is very interesting, because pressure is a form of energy. General relativity predicts that not only is mass gravitationally attractive, but positive pressure is also gravitationally attractive. And so, quite incredibly, negative pressure is predicted to result in gravitational repulsion! As Alan Guth says in The Inflationary Universe: "According to general relativity, a positive pressure creates an attractive gravitational field, as one might guess. A negative pressure, however, creates a repulsive gravitational field." So next time someone says that gravity is a force which is always attractive, you can correct them: negative pressure results in gravitational repulsion!”

“But it is this peculiar behaviour of the gravity spring which enables the universe to have zero total energy.”

“The Schwarzschild radius of the universe is the huge distance of 1.5 × 1027m (calculated from the mass of 1054kg) — a distance which is larger than the radius of the current observable universe. So the whole mass of the universe is contained within its Schwarzschild radius. This means that, for the universe as a whole, the repulsive effect becomes highly-significant. Gravity would act to expand the universe.”

“Though the nature of this missing mass was completely unknown, Zwicky gave the German name "dunkle materie" to the material, which translates to "dark matter". It is now believed that 90% of the mass of the Coma Cluster is in the form of dark matter. Unfortunately, Zwicky was a difficult man to get along with (he was dubbed "borderline psychopathic" in a BBC documentary Most Of Our Universe Is Missing, available on YouTube). Zwicky referred to his colleagues as "spherical bastards" — because they were bastards no matter which way you looked at them. As a result, Zwicky's work was ignored for many decades.”

“relativity, and how to make sense of bizarre quantum mechanical behaviour — were considered in my previous book. I am pleased to say that this new book is going to propose a potentially simple solution to many of the remaining problems. Forces”
