The experiment used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and frame-dragging, the degree to which a spinning object pulls space and time with it as it rotates. GP-B was launched in 2004, designed specifically for this test. 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.
Ten years later a space in time how to#
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. Survivors include his wife, Evi, and his daughter, Jasmin.Einstein was right: There is a four-dimensional space-time vortex around Earth, and the spin of Earth does twist space-time. Lee’s most recent album, “Still on the Road to Freedom,” came out in the fall. Fontana, who had both worked with Presley in his early years. Lee recorded a solo album, “In Tennessee,” with the guitarist Scotty Moore and the drummer D. The name was a homage to the emergence of Elvis Presley about a decade earlier.
The band changed its name to Ten Years After in 1967. Two years later he was performing with the bassist Leo Lyons, and by the 1960s they were playing in a band called the Jaybirds in small clubs in England and Germany. 19, 1944, in Nottingham, and began playing guitar at age 13. After that, it continued to tour and record with a new guitarist, Joe Gooch.Īlvin Lee was born on Dec. Lee played with the band off and on until 2003. Ten Years After regrouped in 1983 and Mr. By the end of the decade he was touring as a solo act and at one point put together a band he called Ten Years Later. He even recorded an album, “On the Road to Freedom,” with a gospel singer, Mylon LeFevre, accompanied by George Harrison, Ron Wood, Steve Winwood and other big names. To me it was a pop song.”īy the mid-’70s Ten Years After had disbanded and Mr. “By then I was rebelling, and I never played it live.
“I hated it because it was a hit,” he said in 2003.
