I think I may have asked this before, but I don't think I received a reply that made sense, at least to me.
Does the gravitational force between distant galaxies become larger and more significant due to their Relativistic Mass at high relative velocities and especially at luminal and Superluminal velocities near and beyond the edge of our observable universe? Would this strong gravitational pull from beyond our universe not want to cause our observable universe to expand even more?
Is the real reason why relativistic mass is not significant because "the speed of gravity" is the same as the speed of light, and so there are many Billions of years of delay in the gravitational field reaching us? And also perhaps for the same reason that we have Olber's paradox when talking about the absence of star light? Also there is a square law reduction in intensity, so perhaps relativisitic mass of individual stars and galaxies only becomes more noticeable during Galactic mergers?
I just read somewhere that since the 1950s (shows how old I am!) Physicists no longer like the term Relativistic Mass. It is still real though correct?
