This paper proposes a physical solution to primordial inflation. It occurs by a scalar field with a slow-rolling period. It starts at the phase transition giving rise to the gravitational interaction at time t_i ~ 10^-44 s, Planck time, and ends at time t_f ~ 10^-42 s (or more exactly about 70 e-folds later). This scalar field is carried by a primordial particle of inert mass m_p ~ 10^-8 kg, and size r_p ~ 10^-35 s. This mass and this time are compliant with the energy density expected at this date, namely 10¹⁹ GeV, obtained from the potential of this scalar field. This solution assumes the existence of particles with negative gravitational mass and positive inert mass, a hypothesis compatible with General Relativity. The incredible adequacy of this solution with what is expected and required by the theory of inflation appears as a strong indication of the validity of both this hypothesis of negative gravitational mass and that of primordial inflation.
