Big Bang explanation.

[felipegalvez]

The Collision of 02 four-dimensional Structures would give origin to 01 three-dimensional Structure + Energy. This theory would explain many of the anomalies of the Universe that the Big Bang cannot explain. As why the material in the exterior of the universe is younger than in the center of the Universe.
The universe is created in its Edges as both four-dimensional Structures interact one against the other. It explains also the X ray Radiation that comes from the exterior part of the universe. Two four-dimensional structures interacting between each other could be expressed by the following formula: (wxyz (wxyz) = xyz E.
The point of the beginning of the collision of these four-dimensional structures would resemble an explosion or Big Bang, and as they are interacting between each other, would resemble an expansion in which the xyz space is created plus the Energy filling this space.
It is possible to have a proportional example, on having pressed two spheres (Three-dimensional spaces xyz) one against the other, a plane (Two-dimensional space xy) is created between them and an also Energy “filling” this plane.

A Brief Introduction to the Ekpyrotic Universe
Paul J. Steinhardt
Princeton University

The Ekpyrotic Model of the Universe proposes that our current universe arose from a collision of two three-dimensional worlds (branes) in a space with an extra (fourth) spatial dimension. The proposal is interesting in and of itself, but also because it is the precursor to a more powerful and explanatory theory, the Cyclic Model described in earlier links on this page.

[that our current universe arose from a collision of two three-dimensional worlds (branes)]

IF the universe started as a Planck length/size singularity or even whatever size it was at T=10^-43, THEN how could there be a collision of anything?

AND, isn't that the very definition of what size Non-Baryonic Dark Matter should be (and therefore, how could it be considered to be a 'brane'?), which is collisionless!

Hum,
it is simply saying that our universe was once a Planck length in size; it was one of many `Planck length points` on the surface of the colliding/interacting branes that inflated.

Ah, very interesting.
