Gravitational lensing

Référence de la vidéo 11927256
Animation showing how gravitational effects from dark matter distorts the shape of a distant background galaxy. The light leaving the galaxy has a circular cross-section initially, but gravitational interactions cause it to be elliptical by the time it leaves the dark matter. Analysis of the changes in the shapes of distant galaxies allow maps to be built up of the distribution of dark matter in that line of sight.
