Einstein is Right!
A survey of the stars using the Hubble Space Telescope has confirmed the accelerating expansion of the universe and Einstein’s ideas about gravity, a team of astronomers said. ………..
The survey, published this week in the journal Astronomy & Astrophysics, confirmed that the universe is expanding at an accelerating rate, propelled by a mysterious force called dark energy. “Our results confirmed that there is an unknown source of energy in the universe which is causing the cosmic expansion to speed up, stretching the dark matter further apart exactly as predicted by Einstein’s theory,” said Van Waerbeke in a statement.
The astronomers were able to find where the dark matter is using a technique called weak gravitational lensing, where light from distant galaxies is observed to bend as it travels through space.
The General Theory of Relativity, a manuscript published by Albert Einstein in 1915, holds that gravity arises because matter warps space and time, meaning that light bends near massive objects, such as the core of a galaxy.
