The motion in a Black Hole spacetime is studied. Several new results are found, in particular about the nature of Dark Matter and Dark Energy. The energy aspect of a matter in curved spacetime is explained. It is understandable why underground detectors for particles of Dark Matter have caught absolutely nothing for so many years of work. Usually, particles have a pretty strong effect on our world. But such small corpuscles as neutrinos have the weakest effect on ordinary matter. I give convincing arguments that Dark Matter acts so weakly on our world that its direct-contact action is equal to zero. That is why Dark Matter passes through the devices that are built for its capture completely without noticing them, completely without labor and friction with these devices. Such Dark Matter is representative for the INVISIBLE world, i.e. the detectors trying to detect it locally are ''blind'', they see nothing.
