Latest Equivalence principle Stories
The discovery of a superdense neutron star in a stellar triple system has made it possible for researchers to collect the best measurements to date of the complex gravitational interactions present in these types of systems, according to a new Nature study.
GARDINER, N.Y., June 23 /PRNewswire/ -- "The Universal Properties of Acceleration: Did Einstein Look the Wrong Way?" (published by AuthorHouse) is about gravity.
In the folklore of physics, no story is better known than the tale of Galileo dropping balls from the Leaning Tower of Pisa and proving that gravity accelerates all objects equally regardless of their masses or composition. But was Galileo correct?
Thirty-five years after Moon-walking astronauts placed special reflectors on the lunar surface, scientists have used these devices to test Albert Einstein's general theory of relativity to unprecedented accuracy. The findings may help to explain physical laws of the universe and benefit future space missions.
General Relativity -- General Relativity is the common name for the theory of gravitation published by Albert Einstein in 1915. According to general relativity the force of gravity is a manifestation of the local geometry of spacetime. Although the modern theory is due to Einstein, its origins go back to the axioms of Euclidean geometry and the many attempts over the centuries to prove Euclid's fifth postulate, that parallel lines remain always equidistant, culminating with the...
