Easier Gravity Measure

Authors: George Rajna

Instead, a kilogram will be defined by choosing an exact value of Planck's constant, a quantity that relates weight to electrical current. [10] A team of researchers affiliated with several institutions in China and one in Russia has devised two new ways to measure the gravitational constant. [9] The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. [8] Using data from the first-ever gravitational waves detected last year, along with a theoretical analysis, physicists have shown that gravitational waves may oscillate between two different forms called "g" and "f"-type gravitational waves. [7] Astronomy experiments could soon test an idea developed by Albert Einstein almost exactly a century ago, scientists say. [6] It’s estimated that 27% of all the matter in the universe is invisible, while everything from PB&J sandwiches to quasars accounts for just 4.9%. But a new theory of gravity proposed by theoretical physicist Erik Verlinde of the University of Amsterdam found out a way to dispense with the pesky stuff. [5]
