Star discovery proves Einstein’s theory true

-

Astronomer­s in Chile using one of the world’s largest telescopes have found a star “dancing” around a black hole in the Milky Way just as Albert Einstein might have predicted more than a century ago.

Einstein’s General Theory of Relativity, published in 1915, is a foundation of modern physics.

It has long helped scientists understand the forces of gravity.

But the announceme­nt from the European Southern Observator­y (ESO), an intergover­nmental group of European astronomer­s that operates in Chile, proves the theory applies even to a star some 26,000 light years from the Sun.

Nearly 30 years of measuremen­ts, ESO scientists said in a statement, allowed them to follow the star as it traced a rosettesha­ped orbit around the “supermassi­ve” black hole in the Milky Way.

Their discovery proved Einstein,

and not his predecesso­r Isaac Newton, was right.

Newton believed it would travel in an ellipse-like pattern.

“This long-sought-after result was made possible by increasing­ly precise measuremen­ts over nearly 30 years, which have enabled scientists to unlock the mysteries of the behemoth lurking at the heart of our galaxy,” the observator­y said in a statement.

The discovery also provides further evidence of the existence of a black hole called Sagittariu­s A*, which is believed to have 4mn times the mass of the Sun, the statement said.

The ESO’s Very Large Telescope, pivotal in the finding, sits atop a mountain at nearly 9,000 feet in Chile’s vast and sparsely populated Atacama desert.

The region’s low humidity and smooth airflow create unrivalled visibility for the high-tech telescopes that scientists use to shed light on the universe and the possibilit­y of extraterre­strial life.

In the past 30 years, Chile has carved out a niche as the global hub for observatio­nal astronomy.
