Actually, I always thought of as the Big Burp after eating too much cold

pizza and kimchi.

First few paragraphs

"The big bang may not have been the beginning of the universe, but merely

the beginning of one of an infinite series of universes. Two fundamental

concepts in physics, both of which explain the nature of the Universe in many

ways, have been difficult to reconcile with each other. European

researchers have developed a mathematical approach to do so that has the potential to

explain what came before the Big Bang.

The big bang singularity --the single point from which the entire universe

is supposed to have sprung-- is the major sticking point in the big bang

theory; the calculations just can't account for such a singularity. Without

evidence associated with the earliest instant of the expansion, the _Big

Bang theory_ (http://en.wikipedia.org/wiki/Big_Bang) does not provide any

explanation for such an initial condition.

According to Einstein’s (classical) _theory of general relativity_

(http://www.dailygalaxy.com/my_weblog/2012/05/is-there-a-fifth-force-that-alters-grav

ity-at-cosmos-scales-.html) , space is a continuum. Regions of space can

be subdivided into smaller and smaller volumes without end.

The fundamental idea of quantum mechanics is that physical quantities exist

in discrete packets (quanta) rather than in a continuum. Further, these

quanta and the physical phenomena related to them exist on an extremely small

scale (_Planck scale_ (http://en.wikipedia.org/wiki/Planck_scale) ).

So far, the theories of quantum mechanics have failed to ‘quantise’

gravity. Loop quantum gravity (_LQG_

(http://en.wikipedia.org/wiki/Loop_quantum_gravity) ) is an attempt to do so. It represents space as a net of quantised

intersecting loops of excited gravitational fields called spin networks.

This network viewed over time is called spin foam.

Not only does LQG provide a precise mathematical picture of space and time,

it enables mathematical solutions to long-standing problems related to

black holes and the Big Bang. Amazingly, LQG predicts that the Big Bang was

actually a ‘_Big Bounce_ (http://en.wikipedia.org/wiki/Big_Bounce) ’, not a

singularity but a continuum, where the collapse of a previous universe

spawned the creation of ours.

European researchers initiated the ‘_Effective field theory_

(http://en.wikipedia.org/wiki/Effective_field_theory) for loop quantum gravity’

(EFTFORLQG) project to further develop this exciting candidate theory reconciling

classical and quantum descriptions of the Universe.

Scientists focused on the _background-independent_

(http://en.wikipedia.org/wiki/Background_independence) structure of LQG which requires that the

mathematics defining the system of spacetime be independent of any coordinate

system or reference frame (background)."
