The detection of this baryonic matter will tend to lend strong support to MOND as opposed to DM theories.
The above result is consistent with cosmological findings indicating that the percentage of Baryonic matter in the Universe is [approximately equal to] 4.
McGaugh said that their work indicates that the largest bound structures, rich clusters of galaxies, have 14 percent of ordinary baryonic matter, close to expected 17 percent.
The baryonic matter, which produces the light and other radiations we observe, must go to the center of each galaxy, leaving outside of itself a sizable halo composed almost entirely of the dark matter.
Moreover, this proposal is not in conflict with the existing theories, because it does not claim that whole of the measured "cosmological red-shift" is due to this "cumulative-phase-alteration-mechanism"; some 5% of the red-shift must be really due to "metric-expansion-of-space", reducing requirement of total-mass-of-the-universe to the observable baryonic matter, making it sufficient for the required "closer-density".
However (5) is strongly violated by the data: the observed baryonic matter density is some 20 times smaller than [[rho].
3], with only a 5% contribution from known baryonic matter, i.
The baryonic matter in a single QCM quantization state produces the correct rotational velocity for the cluster.
