Right from the start ... Shortly after completing his paper on special relativity, in 1905, Einstein realized his equations applied to more than space and time. From the point of view of an ...

Since the beginning of the 20th century, Einstein's theory of general relativity has been the best description we have of how gravity works. However, right around ... the test of time and winning ...

Einstein’s special relativity, which he formulated in his “miracle year” of 1905, was a theory that revolutionised our ideas of space and time ... But his equations turned up a surprise.

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

which is how general relativity gets its name. The theory is a series of equations defined by Einstein. These equations combine space and time to create space-time. Gravity is explained by these ...

he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed, but the result of a curvature of the space-time continuum -- the four ...

The greater the mass, the more extreme the curvature of space-time, and the stronger the influence of gravity. All of this is calculated with the equations that underpin general relativity ...

Optical lattice clocks, the pinnacle of timekeeping, are key to exploring the relationship between quantum mechanics and ...
