This relatively new field applies equations from string theory to solve the questions of early cosmology, since the standard picture of our universe emerging from a big bang leaves many fundamental issues unanswered. String theory, on the other hand, postulates that fundamental ingredients of nature are not zero-dimensional point particles but tiny one-dimensional filaments. This theory Dec 17, 2015 · It’s only major advances in computation that have enabled this to become a fairly well-studied alternative of late, and so work in this is both ongoing and relatively young. 4.) Emergent gravity String theory is a candidate for a unified theory of the four fundamental forces of nature: electromagnetism, the weak force, the strong force, and gravity. Particles in string theory are identified with particular patterns of vibration of a one-dimensional elementary object called a string. String theory is a quantum theory in that the mass spectrum of strings is discrete, so string theory is Jan 9, 2022 · The final theory of the origin of the universe from the late Professor Stephen Hawking, developed in collaboration with Professor Thomas Hertog from KU Leuven, argues against the traditional account of eternal inflation, proposing a simpler and finite universe. Stephen Hawking’s last theory, co-developed with Thomas Hertog, posits a simpler Dec 2, 2023 · multiverse, a hypothetical collection of potentially diverse observable universes, each of which would comprise everything that is experimentally accessible by a connected community of observers. The observable known universe, which is accessible to telescopes, is about 90 billion light-years across. However, this universe would constitute just Oct 7, 2019 · String theory defines pre big bang at Planck scale whose energy is of the order of 1028 eV, length dimension is 10-35 m, mass is of the order of 10-8 kg, time scale is of the order of 10-44 s wgay.
