Matter as Gravitational Waves. Dark Energy

Background: In several previous articles it was exposed the hypothesis that matter could be considered as consisting of gravitational pulses in a six-dimensional space with anisotropic curvature. These pulses interact between them through various mechanisms, one of which is based on time velocity gradient due to gravitational time dilation. As time dilation can also be achieved by speed, physical consequences of this effect are explored. Results Universe expansion, which can be expressed as Hubble's law, causes an effective time velocity gradient , resulting in a repulsive force between any particle-pulsation. This force is mass-independent and causes an acceleration that can be expressed by the relationship a=Ho^2*r ( approximation valid for distances up to 1000 Mpc).Since our best estimate of Hubble's constant value is 71 km/s/Mpc we can estimate the present value of the cosmological constant Lambda at a value of 5.89 10^-53 m^-2. This number is consistent with current observations.
