Gravity is the fundamental force best known for keeping things grounded — literally! Live Science guides you through the history of gravity's discovery, keeps you in the loop about new weighty research and answers all your gravity-related questions.
Whether it’s weird theories of gravity, lost sketches revealing how Da Vinci understood gravity centuries before Einstein, how the tiniest ever gravitational force was measured, or what our universe would look like if gravity just didn't exist, our expert writers and editors keep you down to Earth with the latest gravity news, features and articles
Latest about Gravity
Dead stars sometimes shine again — and gravity itself may be responsible
Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests.
Elusive Planet Nine could be an alternative form of gravity masquerading as a planet, study claims
Astronomers suggest that an alternative concept of gravity, known as modified Newtonian dynamics, could explain orbital inconsistencies that have previously pointed to the existence of a ninth planet in the solar system.
Major CERN experiment proves antigravity doesn't exist — at least when it comes to antimatter
New research showing that elusive antimatter falls downward toward the Earth proves Albert Einstein right yet again.
Rare 'Einstein cross' warps light from one of the universe's brightest objects in this stunning image
Einstein predicted the existence of these crosses back in 1915. Now, they are used to study distant galaxies.
Da Vinci understood key aspect of gravity centuries before Einstein, lost sketches reveal
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.
Scientists reveal 'invisible' galaxy from the early universe, using space-time trick predicted by Einstein
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.
Physicists want to use gravitational waves to 'see' the beginning of time
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.
Something is wrong with Einstein's theory of gravity
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.
