PCS 181 Lecture Notes - Galaxy Rotation Curve, Vera Rubin, Cyclic Model
Future of a closed or oscillating universe: the expansion phase = statements 1-5, at some unknown future time, re-contraction begins. The number of black holes increases and they feast on everything within reach: black holes will meat and coalesce (merge) into one black hole. 5 protons per m^3 (meters cubed)of space. Calculations indicate that if there are 5 protons per m^3, the universe will collapse . Gravity will dominate and re-contract the universe. Resulting in a closed or oscillating universe. Gravitational attraction among all particles is insufficient to close the universe. The sum of all observed luminous matter. Research has concluded that there is not enough matter to re-collapse the universe (luminous matter) This is flawed however, due to the fact that they only studied luminous matter. Neutrinos (small mass moving at the speed of light0. Dark matter (vera rubin proved its existence) A galaxy rotation curve (that rubin constructed) looked at different stars.
