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.
Gaia space observatory , which finished its mission in March, is the best way to possibly detect something like this. It already detected the Gaia BH1, a rogue black hole in the neighbourhood.
The final DR5 data release should be published by the end of 2030.
Earth is located near the center of the Keenan–Barger–Cowie Void, which is rather unusual, and lowers the chance of collisions. We would need a very close flyby, within a few AU, for black hole to pull apart the Moon, or some other very precise stellar billiard to fatally affect us. Something on a highly elongated orbit, coming from an Oort cloud, might be more probable and harder to detect than a massive interstellar object, but also potentially easier to deal with, as we could try to redirect it.
We just bought a boat. It must be a black hole. 🙂
Well, boat is good for solving some problems, but a black hole would solve them all. 🙂
Boat is good for going from prison block A maximum security to prison block C semi open, but it's still a prison block.
