Latest Equivalence principle Stories

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...

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...
