"_Ekpyrotic Model_ (http://en.wikipedia.org/wiki/Ekpyrotic_universe) " of the
Universe that describes our current universe as arising from a collision of
two three-dimensional worlds (branes) in a space with an extra (fourth)

because it is the precursor to a more powerful and explanatory theory, the
_Cyclic Model_ (http://en.wikipedia.org/wiki/Cyclic_model) .
The term ekpyrotic derives from``ekpyrosis" meaning ``conflagration" in
Greek, and refers to an ancient Stoic _cosmological model_
(http://en.wikipedia.org/wiki/Physical_cosmology) . According to the model, the universe is
created in a sudden burst of fire, not unlike the collision between
three-dimensional worlds in our model. The current universe evolves from the
initial fire.* In the public mind, the _Big Bang model_
ilated-into-newly-formed-universe-todays-mo.html) means that the universe
began from a single point, underwent an explosion, and has been flying
apart ever since. However, the big bang is not an explosion at all, rather the
big bang is the expansion or stretching of space with all things are moving
away from each other.The beginning of the big bang picture was the _cosmic
(http://www.dailygalaxy.com/my_weblog/2012/07/new-singularity-in-space-time-found.html) , when the universe has nearly infinite density
There are some skeptics, Steinhardt notes, who have written "the Big Bang
never happened", by which they mean that the universe is not expanding today
and it never has been. They say this despite overwhelming evidence in
favor of expansion and cooling today and for the last 15 billion years.
The Ekpyrotic model does amends the earliest moments of the Big Bang story.
"Instead of beginning with nearly infinite temperature and density,"
Steinhardt writes, "the universe began in a very different state - cold and
nearly vacuous. The hot expanding universe we know came as a result of
collision that brought the universe up to a large but finite temperature and
density. The rest of the story is as the Big Bang model would have it, but the
beginning is different."
The Big bang model, with no amendments, he emphazies, "would tend to
produce a universe that is highly inhomogeneous, with a warped and curved space,
and no natural mechanism for making stars, galaxies and larger scale
structures in the universe. Cosmologists have been trying to correct these
deficiencies by amending the early history of the universe - within the first
billionth billionth billionths of s second or less. One proposal is the
"_inflationary theory_ (http://en.wikipedia.org/wiki/Inflation_(cosmology)) " of
the universe, which proposes that the universe began hot and dense, and
underwent a period of hyperexpansion. The ekpyrotic model is a new alternative,
which is, in many ways, a more radical departure from the Big Bang
The voices in my head may not be real, but they have some great ideas!
