To take things a step further..
Eddington's "Space, Time, and Gravitation" is a book I read repeatedly, as a young man, and one thing that jumped out at me was that a difference of Einsteinian with Newtonian gravity is that the lines of force - forming a gravitational well - converge not to a point, but to a ring the gravitational radius away from the exact center. But this latest work by George F.R. Ellis and colleagues suggests a further generalization that makes sense of the rest.
What if the sphere defined by the gravitational or Schwarzschild radius has no spatial volume, no space-like interior to speak of, and is purely a sphere or ball of time? This sphere that contains a parcel of time could be what sets the duration of mass-bearing objects, in general! It could be said that, in all cases, the existence of mass will cause a sphere of time to arise, which is a place keeper allowing it to persist with locality in space.
This, of course raises questions about whether photons or gravitons, usually thought to be massless, must actually have a minimal rest-mass to fulfill their function - but I'll leave that aside. The real question is how what Ellis calls the formation of an IMOTS or Marginally Outer Trapped Surface, which is purely time-like, might hold the door open while not actually allowing anything to enter - forbidding a Black Hole event horizon from forming. This has the effect of giving ECOs the property of duration in time, or allows them to persist in our universe. In effect; the event horizon contains a finite piece of eternity. This is the embodiment of an old saying from Plato, often attributed to Diogenes, 'Time is the Image of Eternity.'
