Einstein’s Theory of General Relativity Faces Challenge [Video]

Albert Einstein‘s theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable.

This is the conclusion of physicists from the University of Geneva (UNIGE), Switzerland, and the Paul Sabatier University in Toulouse, France, who studied data from a survey mapping the shape of hundreds of millions of galaxies from various points of cosmic history.

When the team analyzed how the mass of these galaxies distorts space-time, they found a slight deviation from Einstein’s predictions that they emerged between 5–6 million years ago.

This change coincides with an acceleration in the rate of expansion of the universe, and so may help shine a light on this puzzling phenomena.
