168 (No, I didn't count them; I used a wee bit of programming.)

So is there any debate on whether this was an artificially induced "flicker" or if it's completely random (or somewhere in between)?

Artificial? Certainly not. Random- not really. It was a naturally occurring, semi-periodic event.

Thanks for your thoughts, neufer. I love the look and feel of that image.

Only the accretion/collision of matter from another star can cause
a neutron star to pass the mass limit so as to collapse into a black hole.
So you're saying radiation pressure simply doesn't/can't apply as it did with the "normal" matter in the star, and that further degeneration into black hole state relies solely on an increase in matter. Interesting.

That matter can collapse into degenerate states sure "feels" to me like what might happen in a mathematical model... In other words, could we and all this be just one big "Universe Simulation 7.0" on a powerful 11-dimensional computer at Supreme Being U?
