ABSTRACT: Dark energy has been introduced in order to explain the
observed acceleration of the expansion of our Universe. It seems to be
distributed almost uniformly and it has an essential influence on the present
value of the Hubble constant which characterizes the rate of this expansion. The
Newtonian theory of gravitation is formulated so that the laws of conservation
of energy and momentum hold. However, the Universe is designed so that the
total amount of energy is slowly, but continually increasing, since its expansion
is accelerating. Our examples show that even the Solar System
and also our Galaxy imperceptibly expand thanks to dark energy whose origins are tiny antigravity forces. We claim that these forces
appear due to the finite speed of gravitational interaction, which causes
gravitational aberration effects. We show that effects of dark energy are
observable; they are not only globally, but also in local systems. These effects can be
measured and are comparable with the present value of the Hubble constant.
