Did the universe begin as a slender thread?

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.


Hubble's deep view of the sky showed myriad galaxies, reaching back to the early history of the universe. The image was assembled from several different exposures taken over 10 days in December 1995. A new proposal suggests that the universe evolves dimensions over time, and that so-called 'dark energy' may be a result of the new fourth dimension.

A universe expanding faster than it ought to be? What's up with that?

To Dejan Stojkovic, the phenomenon astrophysicists discovered in 1998 and labeled "dark energy" may not be as complicated a puzzle as many scientists make it out to be.

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.
