Distant Pulsar Lends New Support for Einstein's Relativity Theory
A recent study is providing new support for a theory that many scientists consider to be one of the two major pillars of modern physics - Albert Einstein's General Theory of Relativity.

The last time I commented on this one the Topix connection crashed.
Suffice it to say that the fact that neutron stars hover mostly around 1.3 to 1.4 solar masses indicates a difference in formation mechanism between neutron stars & stellar mass black holes.
The Magnetars may be a bridging mass mechanism between classic neutron stars & black holes but in their case they should be formed in classic type 1 supernova collapse and be dumped on by the inner part of the outer layers with the ejection velocity of the outer shell a mite lower than average for a type 1. SN 1987A appears to have produced a magnetar (will need to wait for the debris to clear a bit).
The stellar mass black holes may have a completely different core convection feeder structure to a classical supergiant. Best guess so far appears to be an infalling equatorial disc carrying cool fusible material into the core & a polar outflow rich in fusion products cycling back into the equatorial disc.
Problem rests in an upper mass cutoff for neutron stars (magnetars) and a lower mass cutoff for stellar mass black holes.
