Explained: Einstein's theory of general relativity | Science & Tech News

By Alexander J Martin, technology reporter Albert Einstein's theory of relativity – but what exactly is that theory? Dr. Matthew Bothwell, an astronomer at the University of Cambridge "I do not think it's an exaggeration to say that Einstein's general theory of relativity completely revolutionized our understanding of the universe." Nothing about modern cosmology can be Einstein's theories, "Dr. Bothwell …

Einstein's equivalence principle tested near a supermassive black hole

Galactic center photograph. Picture credits: European Southern Observatory (ESO). The GRAVITY Collaboration, a research team of several renowned institutes, including the Max Planck Institute, the LESIA Paris Observatory and the European Southern Observatory, has recently tested part of the Einstein Equivalence Principle, namely the Local Positon Invariance (LPI) in the Near the galactic center supermassive black hole. Their study, published …

Albert Einstein's Theory of Relativity was inspired by the Scottish philosopher

Einstein was suggested to propose his theory of relativity after reading the works of an 18th-century Scottish philosopher. The born theoretical physicist had studied David Hume's A Treatise of Human Nature shortly before proposing a special theory of relativity in 1905. The groundbreaking theory suggested that the speed of light remained the same, even if the observer accelerated or decelerated. …

New equations go beyond Einstein's general theory of relativity

Artistic representation of the effects of gravity on loop quantities in a black hole. The lower half of the picture shows the black hole that captures everything, including light, according to the general theory of relativity. Loop quantum gravity, a theory that expands Einstein's general theory of relativity with the help of quantum mechanics, overcomes this enormous magnetism and frees …

Einstein's "Time Dilation" is precisely measured thanks to groundbreaking satellites

The elliptical orbits of Galileo satellites 5 and 6 enabled researchers to measure gravitational time strain with unprecedented precision. The relativistic eccentricity reaches a peak amplitude of approximately 370 nanoseconds, driven by the shifted height of the satellites (and hence gravity). Periodic modulation of this magnitude is clearly visible given the relative frequency stability of the atomic clocks aboard the …

Einstein's "God Letter", a viral missive from 1954

Peter Klarnet, a leading specialist in American manuscripts at Christie, said science was one of the major growth areas in collecting books and manuscripts. He said the most valuable Einstein letter was a typed copy of his 1939 note to President Franklin D. Roosevelt, which was sold to Christie's for $ 2.1 million in 2002, warning of the possibility of …

Einstein's Theory of Relativity is the first black hole test

Get the Mach newsletter. SUBSCRIPTION More than a century has passed since Albert Einstein gave us the general Theory of Relativity, and scientists are still testing thought-bending theory. In the last test an international team of astronomers used a huge telescope in Chile to observe a star as it moved through the intense gravitational field of a black hole – …

Kids News: Scientists have observed how a black hole distorts light around a star, supporting Einstein's theory of relativity

Scientists know that theory still does not explain everything about the universe. So keep testing it. So far no one has succeeded in replacing it with a better theory. Although the effects of general relativity have been seen before, this was the first evidence * made by observing the motion of a star near a supermassive black hole. 19659002] "That's …
