A space in time4/6/2023 ![]() In the opinion of the committee that I chair, this effort was truly heroic. One day, this will be written up in textbooks as one of the classic experiments in the history of physics. Louis and an expert in Einstein’s theories, said: The space-time around Earth appears to be distorted just as general relativity predicts.Ĭlifford Will of Washington University in St. Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission, said: Artist concept of Gravity Probe B orbiting the Earth to measure space-time, a four-dimensional description of the universe including height, width, length, and time. The findings are online in the journal Physical Review Letters. NASA’s Gravity Probe B (GP-B) confirmed these two key predictions, derived from Albert Einstein’s general theory of relativity. What’s more, as Earth spins, it should cause a twist in the fabric of space-time. Objects moving near that mass roll toward it, much as a ball would roll toward a heavy person sitting on a trampoline. In other words, according to Einstein, mass causes space-time to curve. ![]() The curved lines are caused by the presence of a mass, for example our Earth or sun. What does it mean? As Einstein suggested in his general theory of relativity, published in 1916, gravity can be described as the motion of objects following curved lines in space – or rather space-time, as Einstein more accurately depicted it. NASA announced confirmation of the four-D space-time vortex around Earth on May 4, 2011. ![]() That’s according to NASA, in an announcement made 52 years after scientists first imagined how to test Einstein’s theory on space-time – before the technology to test it had even been invented. ![]() Einstein was right: There is a four-dimensional space-time vortex around Earth, and the spin of Earth does twist space-time. ![]()
