The theory was first unveiled at a conference in University of Cambridge in July 2017 to commemorate Hockings 75 birthday. Hertog, a professor of theoretical physics at Leuven University in Belgium (ThomasHertog), is a co author of the thesis. They carried out a lot of complicated mathematical calculations based on string theory and concluded that the so-called Pluralistic Universe is finite. According to the theory of cosmic inflation, time and space expanded exponentially in the very short time after the big bang. Some scientists have deduced that, on the whole, the universe will expand forever, stopping in only a small part of the universe, and forming an infinite bubble like universe. The visible universe of mankind is one of the bubbles in the expanding space and time. In an interview last autumn, Hocking said, the conventional theory of eternal expansion predicts the universe is an infinite fractal, inlaid with a different pocket universe in the expansive ocean. The physical laws in the bubble, such as the speed of light, are 300000km/s, which can not be applied to other bubbles. These diverse universes constitute a multiverse. I never liked the concept of pluralistic universes. If the different universes in the multiverse are infinite, then the theory can not be verified. Hocking said. In the final paper, Hocking and Horton proposed that the narrative of multiple cosmology is wrong, or, in terms of the metaphor of the title of the paper, to find a smooth exits for eternal expansion. We predict that the universe as a whole is smooth and finite. This is not an infinite fractal structure. Hocking said about the paper. How did this smooth exit be found? The traditional perpetual theory of expansion assumes that the universes overall background is based on Einsteins general theory of relativity, which provides some fluctuations on the basis of the quantum effect. However, the inherent power of eternal expansion eliminates the division of classical mechanics and quantum mechanics, and the theory of relativity collapses. Hocking and he used chord theory to unify relativity and quantum mechanics, so as to recalculate the problem of eternal expansion. String theory is a theory that attempts to unite four kinds of forces. The basic element of nature is a tiny string, which produces basic particles in the process of vibration and motion. Specifically, they borrow the concept of holography in the string theory: the whole universe is a huge and complex hologram, and the physical reality in the three-dimensional space can be mathematically simplified to a two-dimensional plane. Hocking and holog developed a branch of the concept of holography, projecting the time dimension of the theory of eternal expansion, so as to get rid of the dependence on Einstein theory. In this model, the permanent expansion is simplified to a spatial surface on the starting point of time and space. Hockings earlier prediction of the universes boundless conditions predicted that if the universe began, the universe would be closed like a hemisphere. But this paper gives different results: when you go back to a node, you will reach the threshold of eternal expansion. Beyond that threshold, the concept of time well known to mankind will lose its meaning. Now we have to find that there are still boundaries in the past. He said, he said. This new method is used by Hocking and herb to calculate a smooth exits of the theory of eternal expansion, which leads to a limited universe, which is much simpler than the infinite fractal structure constructed by the previous theory of eternal expansion. We have not reduced to a single universe, but our results have greatly simplified the multiverse, and the universe of possible existence is much smaller. He said, he said. This also increases the verifiability of the theory. March 4, 2018 is the last modification time shown in this paper. 10 days later, Hocking died. He will continue to explore on the basis of the paper. He believes that the scale of the new theory may be within the scope of the observation of the human space telescope. In particular, the original gravitational wave, the time ripple produced by the expanding exit, may be the best evidence for verifying the new model. With the expansion of the universe, the wavelengths of the original gravitational wave have exceeded the range of LIGO detection, but the future ESA space gravitational wave detection satellite LISA is expected to hear these rhythms. Just like some of his achievements, Hockings last cosmological theory has been questioned. Professor NeilTurok, of the Canadian Institute of circular theoretical physics, said: I am still confused. Why is Hawking going to think this idea is interesting? WillKinney, a professor at the University of Arts and Sciences in Buffalo, also cautioned that there was no way to find a multiverse in the papers of Hocking and herb. In any case, Hocking and holg used holographic projection to provide a way of thinking to solve the problem of bubbles. AviLoeb, a astrophysicist at the Harvard University, said that the new paper uses mathematics to overcome the mathematical and philosophical bottlenecks and to predict the type of universe that allows the existence of a multidimensional universe. The theory of cosmic inflation has been verified by numerous astronomical observations today, but there are still some final questions to be answered. How does the expansion start? What is the presupposition starting condition for expansion? How does inflation form the present universe? Is inflation everlasting in the past, in the past? Hocking left his last paper, pure theory, pure calculation, pure hypothesis; no observation results, no verification object, no road to the parallel universe. On the ultimate question, it buried a seed that did not know whether it could germinate or rooting.
