SUMMARY
The discussion centers on the relationship between the recessive velocity of distant galaxies and the mass of the universe, as described by Hubble's law. It establishes that galaxies beyond the Hubble sphere can recede faster than the speed of light, with velocities reaching up to 3c. However, this recessive velocity is not an inertial velocity and does not imply an increase in mass due to inertia. The mathematical implications of these velocities are explored, emphasizing that they are consequences of separation distance rather than true motion.
