"Dark matter (DM) may have its origin in a pre-big-bang epoch, the cosmic inflation
. Here, we consider for the first time a broad class of scenarios where a massive free scalar field unavoidably reaches an equilibrium between its classical and quantum dynamics in a characteristic timescale during inflation and sources the DM density," he (https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.123.061302) wrote .
'According to the model of cosmic inflation
, the decay of the false vacuum triggered the Big Bang in one part of expanding space.
The team of cosmologists using the sensitive telescope and array of sensors known as BICEP2, based at the South Pole, announced the discovery of evidence for cosmic inflation
confirming the Big Bang theory of the creation of the universe.
The other, much more recent theory that predicted gravitational waves is called cosmic inflation
. Developed in the 1980s, it starts with the well-accepted idea that the universe began in a Big Bang, an explosion of space-time, 13.8 billion years ago.
Our understanding of the early universe is based on the phenomenon of cosmic inflation
Maybe all the action was just after the Big Bang, lots of life forms feeding off the energy of cosmic inflation
This model of isotropic coordinates of the universe as a black hole could explain the origins of cosmic inflation
, Poplawski contends.
The first of these, cosmic inflation
, was developed in response to the flatness and horizon problems.
The theory of cosmic inflation
, in which the early universe expanded rapidly, bears a mathematical similarity to Hoyle's creation of matter, and in some variations it places the Big Bang's universe inside a larger, older cosmos.
He notes with approval the argument that it is more likely there is a God who designed the universe with us in mind than that cosmic inflation
led to us naturally Considering that the God assumption has no physical evidence to back it up, this is a leap of faith indeed.
"They want to talk about neutrino oscillations, Higgs bosons, cosmic inflation
, and quantum weirdness-the things that excite them.
So, the very early universe could have filled with such knotty flux tubes, the paper's authors speculated, and then found that the amount of energy contained in a tight network of knotted tubes was enough to power the initial cosmic inflation
- a time comprising less than a trillionth of a second during which the universe is thought to have expanded from the size of a single proton to about that of a grapefruit.
