Re: APOD: Massive Black Hole Shreds Passing Star (2015 Oct 28)

(...) If it can't reduce its fusion quickly enough, its production of energy may overwhelm its rapidly shrinking gravity. The star will simply go pop. That's right, degenerate materials at high temperatures would be at the star core, so that would be a tremendous amount of energy just waiting to do...

Is that the core of the star being ejected? It looks almost as if the outer layers were yanked away lea...

Re: APOD: When Black Holes Collide (2015 Oct 20)

I was surprized to see the Einstein ring keeping turning even after the complete absorption of the smaller black hole. I would tend to think that, given that (as madtom pointed out) gravitational information travels at c, once no perturbation is noticeable in the remaining event horizon (i.e the sma...
