Space-Time in a Bottle.


‘This is an epic result,’ adds Clifford Will of Washington University in St. Louis…’One day,’ he predicts, ‘this will be written up in textbooks as one of the classic experiments in the history of physics.’

Using “the most perfect spheres ever made by humans,” a NASA experiment known as Gravity Probe B finds evidence of space-time curvature, as Einstein predicted under general relativity. “Everitt recalls some advice given to him by his thesis advisor and Nobel Laureate Patrick M.S. Blackett: ‘If you can’t think of what physics to do next, invent some new technology, and it will lead to new physics. Well,’ says Everitt, ‘we invented 13 new technologies for Gravity Probe B. Who knows where they will take us?’
