Webb24 juli 2024 · The usual theory of inflation breaks down in eternal inflation. We derive a dual description of eternal inflation in terms of a deformed Euclidean CFT located at the threshold of eternal inflation. The partition function gives the amplitude of different geometries of the threshold surface in the no-boundary state. 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.

I will discuss eternal inﬂation ﬁrst in the context of new inﬂation, and then in the context of chaotic inﬂation, where it is more subtle. 2.1.

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 ]. ricky cucalonWebbEternal in ation [1] refers to the near de Sitter (dS) regime deep into the phase of in ation in which the quantum uctuations in the energy density of the in aton are large.

Our conjecture: The 4D theory describing the evolution of the multiverse is equivalent to a 3D Euclidean theory at the future infinity (suitably defined). dS4 i+ But dS space is metastable, so there is no such thing as asymptotically dS space. 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.
