Naveen congratulates Odia scientist for validating Einstein’s relativity theory

Bhubaneswar: In a major breakthrough in the field of gravitational deflection, a group of astronomers led by Odia scientist Kailash Chandra Sahu have successfully validated Albert Einstein’s general theory of relativity by measuring mass of an isolate object in the galaxy.

The scientists and researchers from the US-based Space Telescope Science Institute (STSI) have finally been able to see this asymmetric phenomenon in action in a star other than Sun by using the superior angular resolution of the Hubble Space Telescope (HST).

Sahu and his team applied the concept to a white dwarf Stein 2051 B which crossed close in front of a more distant normal star. They measured the tiny shifts in the apparent position of the background star through astrometric micro-lensing with the help of HST.

The apparent motion matched the prediction of general relativity and it helped them determine the mass of the white dwarf. A native of nondescript coastal village Bellagam in Ganjam district, Sahu (57), fondly known as planet hunter, was a gold medalist in Physics from Berhampur University in 1977.

Chief Minister Naveen Patnaik has congratulated the scientist. “Odisha born astronomer Kailash Sahu creates history, does what Einstein himself said was not possible,” he tweeted.
