Using an atom interferometer, scientists have tested one of the foundations of Einstein's general theory of relativity: that time slows down in a gravitational field. Their experiment proves that ...
INTERFEROMETERS for the testing and corretion of prisms and of lenses (for axial pencils) have been described in the Philosophical Magazine (vol. xxxv., January, 1918, p. 49). In its simplest form the ...
A team of researchers from the University of Glasgow and the University of Southampton has devised a novel way to test quantum mechanics in a non-inertial reference frame by using a rotating ...

Three spacecraft, six telescopes, and 1.6 million miles: Here’s NASA’s plan to detect hidden gravitational waves
NASA is moving forward with a new all-glass telescope for the Laser Interferometer Space Antenna (LISA), a mission designed ...
Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources. They use two or more flat mirrors to split off or pick off beams from a light source such as a ...
Figure 1: The basic elements of point source interferometry are depicted here. (a) The method starts with a small cloud of ultracold atoms (blue), which is launched upward inside an evacuated ...
A lot of what I write is about measurement, not because I’m in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...
A method that increases the precision of atom interferometers could lead to improved force and energy measurements for testing physics beyond the standard model. An atom interferometer measures very ...
Arvix paper contends the spacetime distortions resulting from the experimentally obtainable electric field of a parallel plate capacitor configuration cannot be detected by the White-Juday Warp Field ...
