I just read a few rambling articles about black holes, but I am none the wiser. The articles suggest that humans are still in the dark about the subject. Even though great discoveries seem to be beckoning, they strike me as highly questionable at best. But does the current ignorance matter in this particular case? Hardly. Humans are not in position to colonize space at this stage of their evolution. The next chance will present itself after the coming glaciation, but there is hardly any way for the extant knowledge to be passed onto our progeny thousands upon thousands of generations ahead of us. Given all the givens, black holes should be left alone. If there is a scientific subject worth understanding right now, it is planet earth. Climate change comes first to mind, but glaciations are not far behind. The two combined represent the greatest threat that humans face at present. And the next dip into the ice should be uppermost on our minds at this time. In addition, the human species itself needs much more scientific research. All sciences brought together need to come up with a better understanding of humans—their strengths and weaknesses, as well as threats and opportunities they face in the fullness of time. Most important, their evolutionary potential needs to be understood much better than is currently the case. For instance, are humans capable of space colonization at all? Returning to black holes, they are not likely to have any palpable bearings upon any of these subjects. They can thus wait for a hundred-thousand years or thereabouts, if not much longer.
