- Three spacecraft flying three million miles apart are to fire laser beams at each other across the emptiness of space in a bid to prove Einstein's theory of general relativity http://www.telegraph.co.uk/science/space/7695994/largest-scientific-instrument-ever-built-to-prove-einsteins-theory-of-general-relativity.html 197 comments science
- A computer model has shown how singularities – which are normally only found at the center of black holes and hidden from view – could exist as in highly curved three-dimensional space. These so called "naked singularities" challenge Einstein's general theory of relativity. http://www.cam.ac.uk/research/news/saddle-shaped-universe-could-undermine-general-relativity 4 comments science
- Satellite test shows objects of different mass dropped in space fall at a rate within two-trillionths of a percent of each other proving the equivalence principle of Einstein’s general theory of relativity & the theory that the absence of air resistance, two objects will fall at the same rate. https://journals.aps.org/prl/abstract/10.1103/physrevlett.123.231102 8 comments science
