Even though Albert Einstein’s theory of Relativity was proven accurate during a solar eclipse in Africa in 1919, the many predictions Einstein made are still being tested experimentally.
After 52 years of planning, delays, experimentation and building a Stanford University team with NASA becomes the latest group to prove that Einstein’s theory is correct.
NASA’s Gravity Probe B mission has confirmed two key predictions derived from Albert Einstein’s general theory of relativity, which the spacecraft was designed to test.
Einstein predicted that the mass of Earth, with its own gravitational force, is enough to bend space-time. Gravity Probe B proved the so-called geodetic effect. Using ultra-precise gyroscopes, NASA scientists confirmed Einstein’s prediction.
He also said that a spinning object pulls space and time with it as it rotates. He called this frame-dragging
This news is enough to make your head spin. Literally. You see in the case of frame-dragging, space around Earth turns at a rate of 37 one-thousandths of a second every year because our planet pulls it round as it revolves – and at a rate predicted by Einstein. But there is still the matter of getting Einstein's theory of relativity -- which applies to big things, like planets, solar systems and the universe -- to reconcile with the theory of quantum mechanics -- which applies to iddy biddy, sub-atomic things. The European Space Agency is already working on that project, called Space-Time Explorer Quest. Scientists are testing test the effect of gravity at the sub-atomic level and hope to have some exciting results that will help the the two theories come together to form the much-sought-after Unified Theory in about 10 years.
