According to our theory, once we cross this distance, the physical constants and parameters change and the physical laws become completely disturbed. At that moment, the speed of the expansion of the universe will reach, according to our theory, approximately 299792.4642 km/sec. This speed of 299792.4642 is slightly higher than the speed of photons (CODATA 299792.458 km/sec). The speed 299792.4642 is not calculated by chance but derived from its connection that we established with the Euler number e=2.718... This connection makes us think that the speed 299792.4642 km/sec is the speed of gravitational waves. In other words, according to our theory, it is very likely that when the speed of expansion of the universe exceeds the speed of photons, and therefore enters a hostile zone, all the cosmological constants and parameters change, notably the gravity which retains the objects in the local zone, etc.!
