Leaning Tower of Pisa Mystery

Authors: George Rajna

Why has the Leaning Tower of Pisa survived the strong earthquakes that have hit the region since the middle ages? [9] New insights into the properties of neutron stars have come from two independent analyses of gravitational waves from the GW170817 neutron-star merger. [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]
