General relativity is founded on the experimental fact that in a gravitational field all bodies fall with the same acceleration regardless of their mass and composition. This is the weak equivalence principle, or universality of free fall. Experimental evidence of a violation would require either that general relativity is to be amended or that another force of nature is at play. In 1916 Einstein brought as evidence the torsion balance experiments by Eotvos, to 10-8–10-9. In the 1960s and early…

On the universality of free fall, the equivalence principle, and the gravitational redshift

Through the contributions of Galileo, Newton, and Einstein, we recall the universality of free fall (UFF), the weak equivalence principle (WEP), and the strong equivalence principle (SEP), in order

Methodology and instrumentation for testing the weak equivalence principle in stratospheric free fall

The use of the GiZero free-fall facility for testing the weak equivalence principle is discussed in this article. GiZero consists of a vacuum capsule, released from a balloon at an altitude of 40 km,

The MICROSCOPE experiment, ready for the in-orbit test of the equivalence principle

Deviations from standard general relativity are being intensively tested in various aspects. The MICROSCOPE space mission, which has recently been approved to be launched in 2016, aims at testing the

‘Galileo Galilei’ (GG): space test of the weak equivalence principle to 10−17 and laboratory demonstrations

The small satellite ‘Galileo Galilei’ (GG) will test the universality of free fall and hence the weak equivalence principle which is the founding pillar of general relativity to 1 part in 1017. It

Torsion-balance tests of the weak equivalence principle

We briefly summarize motivations for testing the weak equivalence principle and then review recent torsion-balance results that compare the differential accelerations of beryllium–aluminum and

IMPROVED TEST OF THE EQUIVALENCE PRINCIPLE FOR GRAVITATIONAL SELF-ENERGY

The lunar-ranging test of the equivalence principle for gravitational self-energy is ambiguous. Although the Earth has more gravitational self-energy than the Moon, its sizable Fe/Ni core also gives

Design and characteristics of a WEP test in a sounding-rocket payload

We describe SR-POEM, a Galilean test of the weak equivalence principle that is to be conducted during the free fall portion of the flight of a sounding rocket payload. This test of a single pair of

Improved determination of G using two methods.

The apparatus has been completely rebuilt and extensive tests carried out on the key parameters needed to produce a new value for G, which confirms the discrepancy of the results with the CODATA value and highlights the wide divergence that now exists in recent values of G.

Abatement of thermal noise due to internal damping in 2D oscillators with rapidly rotating test masses.

This work indicates that proof masses weakly coupled in 2D and rapidly rotating can play a major role in very small force physics experiments.
