Currently two well established physical theories describe the fundamental interactions: quantum field theory - Standard Model and theory of gravity - General Theory of Relativity. Many theoretical works are conducted to combine these two theories to one "Theory of Everything". Concerning the gravity, experimental data are in agreement with Einstein theory of gravity, from the Mercury perturbation motion to time corrections of GPS satellites clocks. However, a number of questions still remains open. Gravity waves and gravitons are, till now, not observed. Another question is how fast the curvature of spacetime can change. Our proposal of the experiment can contribute to the discussion of these problems.
