By accurately measuring w {\displaystyle w} , it is hoped that the cosmological constant could be distinguished from quintessence which has w ≠ − 1 {\displaystyle w\neq -1} . 45 rows 2018-10-10 The research in inflationary cosmology represented below ranges from the original foundations of the theory -- the first working examples, the first gauge invariant derivation of scale-invariant density fluctuations, the first complete computations of the scalar and tensor microwave background predictions -- to exposing the flaws of the theory -- the multiverse problem, the initial conditions problem, and the failed prediction of cosmic gravitational … Inflation (cosmology) has been listed as a level-4 vital article in Science, Physics.

This is assuming that there is some mechanism to bring about the negative pressure state needed for quasi-exponential growth of the scale factor. The role of inflation is just to set up the initial conditions for the conventional Big Bang theory. Now there's a little caveat here. Inflation ends because the material is unstable, but it only ends almost everywhere, not quite everywhere. And this is basically the way exponentials work.

In the classical Big Bang theory this was a problem because the uniform expansion would mean that objects would have to travel many times the speed of light to maintain temperature balance. Inflation is a period in the very early Universe between about [math]10^{-36}[/math] and [math]10^{-32}[/math] seconds after the Big Bang during which the Universe expanded by at least a factor of [math]10^{60}[/math] in size. known as a scalar field, which, in the particular case of inflation, T hirty years ago alan h. guth, then a struggling physics postdoc at the Stanford Linear Accelerator Center, gave a series of seminars in which he introduced “inflation” into the lexicon of cosmology. The term refers to a brief Inflazione (cosmologia) -. Inflation (cosmology) In cosmologia fisica , l'inflazione cosmica , l'inflazione cosmologica , o semplicemente l'inflazione , è una teoria di esponenziale espansione dello spazio nel primo universo .
