Einstein curved space4/6/2023 ![]() ![]() Gravity, argued Einstein, was not an attractive force between bodies as had been previously thought.įew scientists need the final results, which will be revealed in December, to convince them of Einstein's genius. A marble moving along the sagging cloth will be drawn towards the ball, as the Earth is to the Sun, but not fall into it as long as it keeps moving at speed. Everitt's aim was to prove to the highest precision yet if Einstein was correct in the way he described gravity.Īccording to Einstein, in the same way that a large ball placed on a elasticated cloth stretches the fabric and causes it to sag, so planets and stars warp space-time. The joint mission between Nasa and Stanford University uses four of the most perfect spheres - ultra precise gyroscopes - to detect minute distortions in the fabric of the universe. It was Everitt's determination that stopped it being cancelled. The Gravity Probe B project was conceived in the late 1950s but suffered decades of delays while other scientists ran tests corroborating Einstein's theory. 'A scientist starts with a bulldozer, follows with a shovel, then finally uses dental picks and toothbrushes to clear the dust away. 'Understanding the details is a bit like an archeological dig,' said William Bencze, programme manager for the mission. The other, 'frame-dragging', stated that as the world spins it drags the fabric of the universe behind it.įrancis Everitt, the Stanford University professor who has devoted his life to investigating Einstein's theory of relativity, told scientists at the American Physical Society it would be another eight months before he could measure the 'frame-dragging' effect precisely. But this - what is referred to as the 'geodetic' effect - is only half of the theory. ![]()
