The Theory of Relativity is Relative Even In the Far Universe

Not many scientific observations from the past have been held accurately true in the scientifically modern times of today. But the same could not be said for Albert Einstein's theory of relativity which came out a century ago.

Researchers have made a 3D guide of 3,000 galaxies that are 13 billion light years from Earth and observed that Einstein's theory of relativity is legitimate even far, much far into the universe. 

Since it was found in the late 1990s that the universe is extending at a quickened rate, researchers have been attempting to clarify why, and it has been a matter of significant discussion. 

The mysterious dark energy of the universe could be driving the increasing speed, or Einstein's theory of general relativity, which says gravity twists space and time, and could be breaking down. 

To test Einstein's hypothesis, scientists including those from the Kavli Institute for the Physics and Mathematics (Kavli IPMU) and the University of Tokyo in Japan, utilized information on more than 3,000 far off galaxies to break down their clustering and velocity. 

Their outcomes demonstrate that even far into the universe, general relativity is legitimate, giving further backing that the extension of the universe could be clarified by a cosmological consistent, as proposed by Einstein in his 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, Project Researcher at Kavli IPMU.

"Having started this project 12 years ago it gives me great pleasure to finally see this result come out," said Karl Glazebrook, Professor at the Swinburne University of Technology.

Nobody has possessed the capacity to investigate galaxies more than 10 billion light-years away, which is a great distance, yet the group figured out how to break this obstruction on account of the FMOS (Fiber Multi-Object Spectrograph) on the Subaru Telescope, which can dissect galaxies 12.4 to 14.7 billion light years away. 

Here's a video explaining the theory in short and simple steps.
