On July 2nd, a total solar eclipse passed over Cerro Tololo Inter-American Observatory in Chile. A team of students from the University of La Serena attemped to recreate the Eddington Experiment that provided the first experimental evidence for Einstein’s General Theory of Relativity.

Einstein published his general theory of relativity in 1915. Four years later, Arthur Eddington led and experiment to observe the deflection of starlight during a total solar eclipse providing critical evidence supporting Einstein’s Theory. Nearly 100 years later, a team of astronomers and students is attempting to recreate his experiment in Chile during a total solar eclipse on July 2nd.

Seriously, What is Gravity? Another story of gravity about How did Einstein develop General Relativity? What does it mean for different kinds of masses to be equivalent? How does gravity do what it does? Why is curvature so important in understanding gravity?
