NS-Capture Theory predicted the existence of dark matter in 1974
1974 was the year that the NS-Capture theory was discovered as seemingly the only plausible way to explain the spin behavior of Cen X-3 and Her X-1 in the context of information at the time of previously discovered pulsars and their relation to supernova explosions as exampled by the Crab Pulsar and the Crab Nebula.
Once I was convinced that the theory appeared to be correct, I needed to understand the implications of the theory, in particular, to determine how many isolated neutron stars need to be floating around in the Galaxy in order to produce systems like Cen X-3 and Her X-1 on a regular basis to sustain a population of these obviously short-lived (millions of years as x-ray sources or less) objects. I have done some rough calculations recently to review my original conclusions and the result is still that there needs to be approximately (within an order of magnitude) ten (10) or more neutron stars in the Galaxy uniformly distributed among all the other stars.
This requires the Galaxy to have on the order of 10 times as much mass in the form of not yet visible neutron stars, which is roughly same quantity of mass that other researchers have predicted based on other evidence, primarily relating to galactic structure.
Interestingly, the NS-Capture theory predicts both:
- That dark matter must exist making up 90% or more of the total mass of the Galaxy, and
- What that dark matter consists of: namely neutron stars mixed among the normal stars of the Galaxy.
The bottom line is that if one accepts the validity of NS-Capture Theory, then one must also accept the existence of dark matter in the form on neutron stars and NS-Capture theory predicts that it should be possible to observe some of these neutron stars, because they should show some x-ray emission as a result of interacting with material in the interstellar medium.
