New Unified Theory of Dark Matter & Dark Energy

Mathematicians Offer Unified Theory of Dark Matter, Dark Energy, Altering Einstein Field Equations


Sichuan University professor Tian Ma, left, and IU Department of Mathematics professor Shouhong Wang have developed a unified theory of dark matter and dark energy they believe could change our view of energy, gravitational interactions and the structure and formation of the universe.


ScienceDaily (Sep. 6, 2012) — A pair of mathematicians -- one from Indiana University and the other from Sichuan University in China -- have proposed a unified theory of dark matter and dark energy that alters Einstein's equations describing the fundamentals of gravity.

Shouhong Wang, a professor in the IU College of Arts and Sciences' Department of Mathematics, and Tian Ma, a professor at Sichuan University, suggest the law of energy and momentum conservation in spacetime is valid only when normal matter, dark matter and dark energy are all taken into account. For normal matter alone, energy and momentum are no longer conserved, they argue.

"In a nutshell, we believe that new gravity theory will change our view on energy, gravitational interactions, and the structure and formation of our universe," Wang said.

Kevin Zumbrun, chair of the Department of Mathematics at IU Bloomington, said the new unified theory looked sound in principle.

"It is speculative at the cosmological level, since one must match with experiment, but the math is solid," he said. "It's a new and elegant angle on things, and if this does match experiment, it is a huge discovery. Quite exciting!"
