3 days ago · Their investigation builds upon a theorem proved in 2003 by Arvind Borde, Alan Guth (one of the first people to propose the idea of inflation) and Alexander Vilenkin. This theorem, known by the authors’ initials as BGV, says that inflation must have had a beginning — it can’t have been going on ceaselessly into the past.
5 hours ago · Alan Guth, a professor at the Massachusetts Institute of Technology, proposed the idea of cosmic inflation 45 years ago, in part to explain the bland homogeneity of the universe. No matter in what ...
3 days ago · I remember reading about Alan Guth’s idea of inflation to explain the smoothness of the early universe, but if a billion and a half times the energy we currently see as matter was there at the ...
1 day ago · The theory of cosmic inflation, proposed by physicist Alan Guth in the 1980s, suggests that the universe expanded exponentially shortly after the Big Bang. This rapid expansion could have created multiple space-time "bubbles," each of which could be a separate universe with its own physical laws.
1 day ago · Loop quantum gravity ( LQG) is a theory of quantum gravity that incorporates matter of the Standard Model into the framework established for the intrinsic quantum gravity case. It is an attempt to develop a quantum theory of gravity based directly on Albert Einstein's geometric formulation rather than the treatment of gravity as a mysterious ...
22 hours ago · The other key event in the 1980s was the proposal by Alan Guth for cosmic inflation. This theory of rapid spatial expansion gave an explanation for large-scale isotropy by allowing causal connection just before the epoch of last scattering.
4 days ago · The complexity of this equation does not appear justified, since it resolves to: Ʊ=2(4π/T P) 2 /t P. where T P is Planck temperature and t P is Planck time. This follows from T P =E P /k b where E P =m P c 2 is Planck energy and k b is the Boltzmann constant, noting that m P =√(ħc/G), so that:
