Summary
... Earth is round because of gravitation. Earth attracted itself together before it became solid. Any “corners” of Earth have been pulled in so that Earth is a giant sphere. The solar system began when a slightly rotating ball of interstellar gas contracted due to mutual gravitation. To conserve angula ...

Introduction Contact Weak Lensing: Method The NOAO Deep Wide
... There are two types of gravitational lensing: strong lensing occurs when the curvature is great enough to cause multiple imaging—the same background object is seen in multiple directions! This yields very detailed information about the mass, but requires a significant mass density. In weak lensing, ...
