≪The study of gravity has led to many revolutions in science, from Newtonian Dynamics to General Relativity to Quantum Field Theory. Despite these advances, however, gravity continues to puzzle scientists. In the 17 century, Sir Isaac Newton was able to successfully model the gravitational force on a macroscopic scale, but in the succeeding 400 years physicists have made little progress in unde...

Extreme-mass-ratio inspirals (EMRIs), stellar-mass compact objects (SCOs) inspiralling into a massive black hole, are one of the main sources of gravitational waves expected for the Laser Interferometer Space Antenna (LISA). To extract the EMRI signals from the expected LISA data stream, which will also contain the instrumental noise as well as other signals, we need very accurate theoretical t...

We apply the principle of energy conservation to the motion of the test particle in gravitational field by requiring that its energy, gained by gravitation, has to be balanced by decrease of its rest mass. Due to the change of mass in gravitational field Newton's force law between gravitating bodies is modified, too. With this modified force law we build up the the classical field theory of gra...
