Theory of eternal inflation summary
WebbInflation answers many of the unresolved questions of the Big Bang and predicts the observable universe that we see when we look up on a clear night. Although there have been many models of inflation over the decades, the most enduring is Linde’s chaotic inflation. His theory of “eternal chaotic inflation” followed in 1986. Webb19 sep. 2024 · The inflationary scenario [ 1, 2, 3, 4, 5] is the current paradigm of early universe cosmology. In addition to explaining the homogeneity, spatial flatness and large size of our universe, the accelerated expansion of space provided by inflation yields a mechanism to explain the origin of structure in the universe [ 6, 7 ].

WebbIn 2000, Raphael Bousso and Joseph Polchinski proposed using the regime of eternal inflation and transitions between many different vacua in string theory for solving the cosmological constant problem. At that time, no stable or metastable vacua of string theory were actually known. ap seminar performance task 1 2023Webb2 jan. 2024 · In this paper, we propose that cosmological time is a quantum observable that does not commute with other quantum operators essential for the definition of cosmological states, notably the cosmological constant.
