Lately I've been intrigued by the concept of "dark matter" and "dark energy." Wiki those topics and just read the synopsis. It's the idea that something is holding our universe together. It's the foundation and structure that defines how fast a galaxy spins, where space gas accumulates, or how stars burn.
Gravity, light, energy, mass, wavelengths, etc. I think there's a few more "real world" phenomena that has yet to be discovered and it involves the 90% of our universe that we don't understand.

I'm an ex-amateur astronomer, but still an enthusiast. I know about dark matter and energy,

and of course there are things we don't understand in cosmology, that's not in question. But we don't have to know everything about the universe before we can begin to understand individual parts of it. Black holes=real.
We aren't guessing at the existence of black holes, we know they're there - we're just unsure of all their properties.
