Sentences with phrase «inflationary cosmology»
Inflationary cosmology is a concept in astronomy and physics that explains the rapid expansion of the universe shortly after the Big Bang. It proposes that the universe underwent a brief period of incredibly fast and exponential growth, similar to a balloon being blown up quickly. This theory helps us understand why the universe appears so uniform and why the galaxies are spread out the way they are. Full definition

Similarly inflationary cosmology doesn't claim that the entire universe derived from a point, not even that the observable universe did.
The fashion is string theory; the fantasy has to do with various cosmological schemes, mainly inflationary cosmology [which suggests that the universe inflated exponentially within a small fraction of a second after the Big Bang].
Carroll's model of the multiverse depends on a speculative interpretation of inflationary cosmology, which is itself only loosely verified.
Observations show that the universe is in fact flat (there is just enough matter to slow its expansion but not to halt it), has zero total energy and underwent rapid inflation, or expansion, soon after the big bang, as described by inflationary cosmology.
In other words, we need to know the statistics of variation in the laws of physics of pocket universes — and in inflationary cosmology there is no principle that guides the choice of physics in each of them.
During the early 1990s Smolin proposed a multiverse model that differs strongly from inflationary cosmology's pocket universes.
This attractive force between branes would in fact be a special case of the kind of force that inflationary cosmologies posit to explain the early universe's blowup.
Invoking inflationary cosmology, he submits that each of these theoretical possibilities has actually bubbled into existence as a «pocket universe.»
Such inflationary cosmologies have worked so well they've crowded out all the competition.
But inflationary cosmology has shown that the putative «magic seed» of creationists is diluted at least 10 ^ 150 times!
Inflationary cosmology, currently the dominant model of the early universe, holds that the entire observable cosmos began as a speck within a far larger (perhaps infinite) existence emerging from the Big Bang.
Of course, Lucretius had never heard of quantum mechanics and inflationary cosmology, 20th - century fields that contest his bold claim.
Inflationary cosmology, which is our best theory for what happened right after the Big Bang, says that a tiny chunk of space underwent a period of rapid expansion to become our universe.
When coupled with an inflationary cosmology, the authors» approach predicts that a charge asymmetry should have been produced at ultra-minute fractions of seconds after the Big Bang.
