Within a pretty short period of time, we had three extrasolar objects of significant size (1I/ʻOumuamua, 2I/Borisov and 3I/Atlas) pass through the inner solar system. How much of a coincidence that is would depend on whether this happened before and we just didn’t have the technology to notice, but let’s assume this is indeed a new occurrence.

Some people are trying to see aliens there, but I don’t see any evidence of that. However, I think something more dangerous might be at play. I think we are passing through the Oort cloud of something massive enough to have one, and dim enough not to register on our telescopes.

Furthermore, since the comets are intersecting with the inner solar system, and not, for instance, the Kuiper belt, it means it’s coming straight at us.

Is it a black hole, or some other dark object of stellar mass, I can’t tell, and this is all a hypothesis, but still, I wanted to write it down.
