Einstein has once again been proven right, thanks to the findings of a 16-year-study of a pair of 'extreme stars' known as pulsars, with the results matching what would be expected under his theory of general relativity.

General relativity is the best theory of gravity we have come up with so far, but is not compatible with the other fundamental forces, described by quantum mechanics. 

Scientists are constantly trying to prove all or part of the theory, proposed by Albert Einstein in 1915, to be wrong, as this would 'change physics as we know it'.

The latest attempt came from experts at the University of East Anglia and the University of Manchester, who used binary pulsars as a gravity laboratory.  

Not only did their findings back up Einstein's predictions, but they were able to witness light being delayed by the strong curvature of spacetime caused by gravity.

The British researchers were part of an international team looking at the pulsars through seven radio telescopes located around the world.

The study, published in the journal Physical Review X, reveals new relativistic effects that, although expected, have now been observed for the first time.
