redOrbit Staff & Wire Reports - Your Universe Online 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 study in Nature. Using the National Science Foundation's Green Bank Telescope (GBT), the study authors were able to locate the pulsar along with two white dwarf stars in a compact area...

GARDINER, N.Y., June 23 /PRNewswire/ -- "The Universal Properties of Acceleration: Did Einstein Look the Wrong Way?" (published by AuthorHouse) is about gravity. Author Barry Lebost proposes a new law in physics stating "that all acceleration and its intimate partner inertia have the same general properties everywhere in the universe including the surfaces of planets and stars." Lebost demonstrates that when universal property tests are performed upon the surface of planet Earth, the test...

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. This is called the "equivalence principle," and it is a cornerstone of modern physics. But was Galileo correct? NASA -- Standing on the Moon in 1971, Apollo 15 astronaut Dave Scott held his hands out at shoulder height, a hammer in one hand and a feather in the other. And...

NASA -- 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, which also confirm theories from Galileo Galilei and Isaac Newton, may help to explain physical laws of the universe and benefit future space missions. "Our research with the Lunar Laser Ranging experiment probes the equivalence principle, a foundation of...

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...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
