Equivalence Principle Tests

The Equivalence Principle assumes a constant 1g acceleration:

  “ Another clarification needed is that the equivalence principle assumes a constant acceleration of 1g without considering the mechanics of generating 1g. ”

Physicists also often assume a uniform gravitational field. Professor Vincent Buonomano at the State University of Campinassays:

  “ We always assume a uniform gravitational intensity unless stated otherwise. ”

Searching for Extra Dimensions

From the introduction of Searching for Extra Dimensions and New String-Inspired Forces in the Casimir Regime (Archive), its authors Dr. Dennis E. Krause (bio) and Physics Professor Ephraim Fischbach (bio) tell us:

  “ When Isaac Newton formulated his law of universal gravity over 300 years ago, he provided the first mathematical description of one of the fundamental forces of nature. Yet, physicists have realized only relatively recently that tests of Newtonian gravity can still provide a unique window into new physics [1-7]. Within the past 20 years, experimentalists have put Newtonian gravity to the test for distance scales 10^-3-10¹⁵ m by searching for violations of the weak equivalence principle (WEP) and inverse square law (ISL). The fact that no such violations have been observed places stringent constraints on extensions of the Standard Model that would naturally lead to such effects [1]. ”
