Scientists at Durham University in the U.K. have produced massive supercomputer simulations of the universe to test whether the Chameleon Theory (f(R)-gravity) could explain the formation of cosmological structures.

This research demonstrated that the theory, which can replicate the success of General Relativity in showing the evolution of our solar system, also is applicable to galactic formation.

Rather than invalidate Einstein's relativity equation, the f(R)-gravity research suggests multiple ways of describing gravity's role in universal expansion.

Simulations like f(R)-gravity also can explain the universe's rapid expansion.

The Durham researchers think their work also could help provide clues about the nature of dark energy.
