Further Constraining of Dark Matter Candidates

Scientists continue to narrow a significant gap in a key component of RTB’s cosmic creation model—namely, big bang cosmology. While scientists almost universally agree on the existence of dark matter, its identification and properties remain elusive. Consequently, physicists have proposed many different proposals for the nature of dark matter. One such dark matter candidate, known as massive compact objects (MCOs), has been ruled out by observations of type Ia supernovae (exploding stars). Had MCOs comprised the bulk of the dark matter, they would have left a particular signature in the observed properties of a large ensemble of type Ia supernovae. That signature was not seen; thus, dark matter does not consist predominantly of MCOs. The pool of dark matter candidates continues to dwindle and scientists are optimistic that dark matter will be directly detected in the near future. These and future results continue to fill in the details of RTB’s model.
