The assumption of a speed of travel of c leads to a pair of pulsars
approaching one and other at 7mm/day

/news/einstein/

No other speed gives that figure and that figure has been confirmed
experimentally to be correct. More recent result and more precise than
the Nobel Prize.

Gravity is associated with matter in any form. It does not matter
whether it is crushed quark, or even black holes.
