"... Big Bang model does not fit into the mapped universe. ... It is time now for the re-examination of Big Bang cosmology." According to Famaey and McGaugh,
"Either (i) there is a vast amount of unseen mass in some novel form--dark matter-- or (ii) the data indicate a breakdown of our understanding of dynamics on the relevant scales, or (iii) both."

Please consider 4 questions:
(1) Does MOND have many empirical successes?
(2) How likely is it that dark-matter-compensation-constant = 0 ?
(3) How likely is it that dark-matter=compensation-constant = (3.9±.5) * 10^-5 ?
(4) How likely is it that dark matter particles exist?
