In a previous paper, we demonstrated that the
linearized general relativity could explain dark energy (the experimental
values of parameters ΩΛ, the cosmological constant, the recent acceleration
of the expansion of our Universe) offering an amazing image of our universe at
an incredible scale. This explanation of dark energy relies on the assumption
of the existence of a negative gravitational mass (with always a positive
inertial mass meaning that gravitation could be repulsive). This article demonstrates
that this assumption is not only compliant with general relativity but even
that the repulsive gravitational interaction is inscribed in the equations of
the general relativity. The absence of negative gravitational mass should then
be justified because nothing forbids its existence and until now repulsive
gravitation has never been observed. This natural possibility of general
relativity must be then avoided by adding an ad hoc paradigm.
In a way, the principle of masses’ equivalence plays indirectly this role. We
will show why this principle can be verified with a great accuracy but we also
propose experiments that could violate this principle, allowing at the
same time rejecting its status of theoretical principle. This
frame of explanation (general relativity released from this ad hoc constraint)
opened then
the way of the negative gravitational mass with its natural corollary, the
repulsive gravitational interaction, and of the following major predictions: the antimatter should have a negative
gravitational mass, the neutrino should
not be a Majorana particle, the principle of equivalence of masses
should be violated for the antiprotonic helium, the apparent
disappearance of antimatter could be explained. We recall some other
consequences: an “initial” cosmic inflation
would be unavoidable, dark energy (or cosmological constant) might not
be constant in time (causing accelerating universe). Several experiments are
testing some of these predictions: NEMO experiment tests if neutrino is a
Majorana particle, and AEgIS, ALPHA and GBAR experiments at CERN test the
behavior of the gravitational interaction on anti-matter and the sign of its
gravitational mass. First results could be obtained in 2018. Experiments are
proposed to test the violation of the principle of equivalence of the masses.
