Improved geodetic European very-long-baseline interferometry solution using models of antenna gravitational deformation
very long baseline interferometry antenna deformation signal path variation crustal deformation height bias
2015/8/28
Very-long-baseline interferometry (VLBI) is used for establishing global geodetic networks where the coordinates attain a 1-mm level of precision. Technique-dependent bias can degrade the VLBI positio...

While airplane and rocket experiments have proved that gravity makes clocks tick more slowly — a central prediction of Albert Einstein's general theory of relativity — a new experiment in an atom inte...
A new gravitational model for dark energy
dark energy de Sitter gauge theory of gravity torsion
2009/8/17
A new gravitational model for dark energy is presented based on the model of de Sitter gauge theory of gravity. In the model, in addition to the cosmological constant, the homogeneous and isotropic to...
Gravitational waves are vibrations of space–time predicted by the general theory of relativity. A number of experiments are trying to detect gravitational waves by measuring tiny changes in the separa...
