Abstract For decades, two aspects of nature have been overlooked and poorly / not understood. The one is an Anisotropic Dark Flow Acceleration (DFA). The other is Relativistic Resistance against Motion (RRM). The consequences for our picture of the Universe are tremendous. (This is a beta version)..   PART 1 Anisotropic Dark Flow Acceleration. In order for even a rather significant Anisotropic Acceleration to be measurable on Earth (e.g. with a gravimeter), it requires rather specif
