  Astronomers have used the sharp vision of NASA’s Hubble Space Telescope to repeat a century-old test of Einstein’s general theory of relativity. The Hubble team measured the mass of a white dwarf, the burned-out remnant of a normal star, by seeing how much it deflects the light from a background star. This observation represents the first time Hubble has ...

Pune-based physicist Thanu Padmanabhan propounded the theory that dark energy in cosmology is the root cause of accelerated expansion of the universe and threw a challenge to peers to prove him wrong giving them a decade in 2006. Now that the ten years are over, research could not prove him wrong and he won the challenge. A renowned scientist from ...

The phenomena of an Einstein ring that was predicted by Einstein’s theory of General Relativity but remained a mystery has recently been discovered by researchers. An Einstein ring is a distorted image of a very distant galaxy, which is termed “the source” that produces the bending of the light rays due to a massive galaxy, termed “the lens”, lying between ...

Star Trek-style ‘warp speed’ space travel between galaxies is theoretically possible, based on Einstein’s Relativity theory, insists astrophysicist from the University of Sydney in Australia. Professor Geraint Lewis, from the University of Sydney, says the futuristic concept is possible if we know how to build a warp drive. “It’s theoretically possible, but can we ever build a warp drive? We ...
