A new framework for the universe's formation suggests that it began as a single thready line, then evolved into a plane, and only then the three-dimensional space we now inhabit. This could simplify sticky cosmological questions, including dark matter and gravity waves.

A universe expanding faster than it ought to be? What's up with that?
Instead, he suggests, it's the signal that a fourth dimension – beyond the height, width, and depth humans are geared to experience – has opened up in a universe that is adding physical dimensions as it evolves.
This possible explanation for dark energy results from applying a new "framework" for looking at the evolution of the universe that he and colleagues have developed over the past two years. Working backwards in time, the concept also implies that the universe did not begin its existence in a three-dimensional form, but as a one-dimensional structure that added dimensions as it evolved.
Some support for this may be found in high-energy cosmic rays, according to Dr. Stojkovic, a physicist at the State University of New York at Buffalo, who along with colleagues first proposed the idea last year.
In a paper published recently in Physics Review Letters, Stojkcovic and colleague Jonas Mureika of Loyola Marymount University in Los Angeles write that further tests of the framework's validity could come from the Large Hadron Collider in Geneva as well as from planned space missions to detect gravity waves thought to be rippling through the cosmos.
