On the nature of space-time, cosmological inflation, and expansion of the universe.

We propose to investigate the mechanism of cosmological inflation and expansion through the physical properties of space-time [1]. We demonstrate that a cosmological inflation scenario occurs when the bulk modulus of space-time K=1.64×10¹⁰⁹N.m^-2, and show that the dark energy density is decreased by a factor of 10¹²² while the scaling factor expands from 10^-60 to 10^-32 during a time of the order of 10^-42 s. At the end of the presentation, we discuss a microscopic interpretation of the inflation mechanism and future investigations on longitudinal waves.
