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 ].
