Residents in Hiroshima observed a minute of silence today marking the 72nd anniversary of the first atom bomb usage on August 6, 1945 by the US to end World War Two, bringing peace to the world but the death toll has climbed up to 164,621 so far. The event at Hiroshima’s memorial park was witnessed by people who released thousands ...

Einstein Relativity Tehory Comes Handy to Find Dwarf Star’s Mass

Looks can be deceiving. In this Hubble Space Telescope image, the white dwarf star Stein 2051B and the smaller star below it appear to be close neighbors. The stars, however, reside far away from each other. Stein 2051B is 17 light-years from Earth; the other star is about 5,000 light-years away. Stein 2051B is named for its discoverer, Dutch Roman Catholic priest and astronomer Johan Stein.CREDIT: NASA, ESA, and K. Sahu (STScI)

  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 ...

Perfect ‘Einstein Ring’ 10000 Light Years Away Discovered

einstein ring

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’ kind of ‘Warp Speed’ Possible Theoretically: Astrophysicist Lewis

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 ...
