Einstein predicted the existence of these crosses back in 1915. Now, they are used to study distant galaxies.
Sketches found inside Leonardo da Vinci's sketchbooks, show that he had already grasped the essence of Einstein’s 1907 ‘Equivalence Principle’ centuries before the physicist.
Using the ALMA telescope in Chile and Einstein's theory of relativity, scientists observed a young galaxy in the early universe that is invisible in nearly every wavelength.
Gravitational waves are ripples in the fabric of space. Waves that originated in the early universe could carry important information about the phenomena that occurred there.
Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales.
The test chamber will enable scientists to test technologies and structures on Earth before sending them to the moon.
Physicists turned on a new type of gravitational-wave sensor and saw two intriguing results, but they aren't yet ready to claim a discovery.
Certain weird gravity conditions would make it possible to travel through a wormhole and back.
