A new code of numerical simulations have been developed which offers a glimpse of the complex process of the formation of structures in the universe. Based on Albert Einstein’s equations, the physicists at the University of Geneva were able to integrate the rotation of space-time into their calculations and calculate the amplitude of gravitational waves, whose existence was confirmed for the first time on February 12, 2016.
Until now, scientists studied the formation of large-scale cosmological structures based on numerical simulations of Newtonian gravitation. These codes postulate that space itself does not change and is said to be static, while time goes on.
The simulations, that it allows, are very precise if the matter in the universe moves slowly i.e. about 300 km per second.
Further, it does not describe the fluctuations of dark energy. Constituting 70 percent of the total energy of the universe, it is responsible for the accelerated expansion of the universe. Therefore, it was necessary to find a new way to simulate the formation of cosmological structures and allow the study of these two phenomena.
This study has been published in the journal Nature Physics.
