A compact object captured by a supermassive black hole, named as extreme-mass-ratio inspiral (EMRI), is one of the most important gravitational wave sources for low-frequency interferometers such as LISA, Taiji, and TianQin. EMRIs can be used to accurately map the space-time of the central massive body. In the present paper, we introduce our recent progress on testing gravity theory with EMRIs. We demonstrate how to constrain gravitational wave dispersion and measure the deviation of the central body from the Kerr black hole. By using binary-EMRIs, the gravitational recoil and mass loss due to merger will be measured in a higher accuracy compared with the current LIGO observations. All these potential constrains and measurements will be useful for test of the gravity theory.

Compton Scale

We show that the rotating black hole solutions bring new effects in the particle physics, allowing to unite gravity with quantum theory. Due to extremely large spin/mass ratio (for typical spinning particles), the rotating Kerr black hole solution deforms space topologically on the Compton scale, which increases extremely effective influence gravity on quantum processes, and gravity starts to collaborate with quantum processes, instead of confront them. In particular, Kerr’s gravity defines several important structures and parameters of electron, in particular, its non-perturbative shape, the associated Wilson loop, features of the used supersymmetry and specials of the stringy system.
