Einstein's Theory of Relativity Is Credible Even For Galaxies 13 Billion Light Years From Earth

Scientists recently created a 3D map of 3,000 galaxies located 13 billion light years from our planet, according to a report. Interestingly, the researchers discovered that the general theory of relativity by Albert Einstein holds true and even applies to far off areas in the universe.

In the 1990s it was discovered that the universe is expanding at a fast rate, and since then scientists have been trying to find an explanation for the occurrence. As per reports, the acceleration or fast paced expansion could be driven by mysterious dark energy or Einstein's theory of relativity could be breaking down. Incidentally, the theory says gravity warps space and time, i.e. what we comprehend as the force of gravity actually arises from space and time curvature.

To test Einstein's theory, researchers from the University of Tokyo and Kavli Institute for the Physics and Mathematics (Kavli IPMU) in Japan analyzed the clustering and velocity of more than 3000 distant galaxies. The study report suggests that the concept of general relativity is valid even in the remote universe, and its expansion can be explained by a cosmological constant, as forwarded by Einstein's theory of general relativity.

"We tested the theory of general relativity further than anyone else ever has. It's a privilege to be able to publish our results 100 years after Einstein proposed his theory," said Teppei Okumura, from Kavli IPMU. Until now, no one has been able to observe galaxies that are located more than 10 billion light years away. However, the team of researchers from Japan managed to achieve this feat by using the Fibre Multi-Object Spectrograph (FMOS) on the Subaru Telescope, which can study galaxies located as far as 12.4 to 14.7 billion light years away. At present, the Prime Focus Spectrograph is being built that will allow scientists to observe galaxies at an even greater distance.
