In a few thousand years of recorded history, we went from dwelling in caves and mud huts and tee - pees, not understanding the natural world around us, or the broader universe, to being able to travel through space, using reason to ferret out the hidden secrets of how the world works, from physics to chemistry to biology, we worked out the tools and rules underpinning it all, mathematics, and now we can see objects that are almost impossibly small, the very tiniest building blocks of matter, (or at least we can examine them, even if you can't «see» them because you're using something other than your eyes and photons to view them) to the very farthest objects, the planets circling other, distant stars, that are in their own way, too small to see from here, like the atoms and parts of atoms themselves, detected indirectly, but indisputably THERE.

There are two different black hole scenarios proposed to explain these objects: (1) they contain very «big» black holes that could be more than a thousand times more massive than the Sun (Note 1), or (2) they are relatively small black holes, «little monsters» with masses no more than a hundred times that of the Sun, that shine at luminosities exceeding theoretical limits for standard accretion (called «supercritical (or super-Eddington) accretion,» Note 2).
