Scientists studying a supermassive black hole at the centre of the Miky Way have finally confirmed Albert Einstein's theory of general relativity a 100 years after he first proposed it. By accurately recording the orbits of stars around the black hole, referred to as Sagittarius A*, that's 26,000 light years from Earth and four million times the mass of the sun, the scientists suggest that Einstein was right all along. Einstein's general theory of relativity, introduced to the world in 1915, hypothesised that gravity was due to the curvature of space and time, produced by the distorting effect of massive objects like stars and planets, in much the same way as a bowling ball placed on a trampoline curves its surface. The researchers analysed around 20 years of observations from the European Southern Observatory's Very Large Telescope (VLT) in the Atacama Desert of northern Chile as well as other sources to analyse the movements of three stars in orbit around Sagittarius A*, and found it doesn't match up with the predictions of Newtonian gravity. Although it's a significant result, the researchers admit that due to the limited precision afforded by the historical observational data used in the study it is only preliminary for now.
