Germani's alternative, unveiled at a cosmology conference at the
University of Sussex, UK, last month, is based on a string-theory
model in which the three visible dimensions of space are confined to
the surface of a membrane, or brane, floating in a 10-dimensional
space. The extra dimensions are wrapped up into a complex shape known
as a Calabi-Yau space. The forces and particles in
our 3D world are shadows of the motion of branes and strings in the
Calabi-Yau space.

The problem with the simplest versions of this model is that the
Calabi-Yau space is unstable, constantly vibrating and changing size.
Each wobble of the surface creates unwanted particles and extra forces
in the universe - none of which have ever been observed. Attempts by
string theorists to stabilise the space always warp it, forcing
strange spikes and throats to pop out, Germani says. This warping, he
believes, is the key to explaining the evolution of our universe.

"We don't have any fundamental physical explanation for how or why it occurred," he says. "Yet cosmologists today accept it as though it is a religion."

But science leaves open the arms for further investigation by all, so it can get better and closer to the truth. Religion is the opposite. It starts with a supposed truth and then closes its ears to everything else.

Big difference.

This theory has been around a while. If I'm not mistaken, Stephen Hawking cited this as a possibility in his 1980something book.
