The general relativistic prediction of the Lense-Thirring effect has been confirmed to a precision of less than 10%. The result was obtained by measurements of the position of two satellites over a pe...
Read article 'Do gamma rays indicate galactic dark matter?'
Is the recent detection of very-high-energy gamma rays from the galactic centre revealing the presence of dark matter? Or, is dark matter at the origin of the electron-positron annihilation in our gal...
