A group of scientists has created a computer simulation of the universe in order to test out an alternative theory to Albertn Einstein's theory of general relativity.
Their study found that galaxies similar to our own Milky Way could still form in the universe with modified laws of gravity, suggesting that the theory of relativity is not the only way to explain gravity's role in the evolution of the universe.

Physicists from Durham University in England created the computer simulations using a leading alternative model for gravity called "f(R)-gravity," also known as the "Chameleon Theory," which alters the behavior of gravity according to the surrounding environment. The simulations showed that the modified gravity model could still lead to galaxy formation.

"Modified gravity theories, including [the] Chameleon Theory, had been studied by the community for a while, and a lot of their predictions were known," Baojiu Li, a physicist at the Institute for Computational Cosmology at Durham University and co-author of the new study, told Space.com. "However, the majority of these previous studies were conducted with a critical simplification — the assumption that the universe contains only dark matter, and no luminous matter."
One of the unanswered questions in cosmology is the reason that the universe is expanding, Li said, and other models have tried to answer that question by introducing an unknown force called dark energy. This constant force in the theory of general relativity can account for the expansion of the universe, but does so by including a vast...
