"Planet Nine is a compelling explanation for the observed clustering of some objects beyond the orbit of Neptune. If the existence of Planet Nine is confirmed through a direct electromagnetic search, it will be the first detection of a new planet in the solar system in two centuries, not counting Pluto, said Siraj, adding that a failure to detect light from Planet Nine -- or other recent models, such as the suggestion to send probes to measure gravitational influence -- would make the black hole model intriguing. "There has been a great deal of speculation concerning alternative explanations for the anomalous orbits observed in the outer solar system. One of the ideas put forth was the possibility that Planet Nine could be a grapefruit-sized black hole with a mass of five to ten times that of the Earth."
The focus on Planet Nine is based both in the unprecedented scientific significance that a hypothetical discovery of a planet-mass black hole in the solar system would hold as well as the continued interest in understanding what's out there. "The outskirts of the solar system is our backyard. Finding Planet Nine is like discovering a cousin living in the shed behind your home which you never knew about," said Loeb. "It immediately raises questions: why is it there? How did it obtain its properties? Did it shape the solar system history? Are there more like it?"

Been wanting to know what that is for a while.

When do we send Matthew McConaughey through?

Primordial black holes are a hypothetical type of black hole that formed soon after the Big Bang. In the early universe, high densities and heterogeneous conditions could have led sufficiently dense regions to undergo gravitational collapse, forming black holes. - Wikipedia
A conundrum that I’ve never seen addressed in physics is the density and mass of the Universe at the time of the Big Bang. That it exceeded even the most supermassive black hole in existence seems a foregone conclusion.
We know how black holes form in our post-Big Bang Universe, and we can theorize how they may have formed shortly after the Big Bang, as in the example we’re discussing in this thread, but speculation seems to falter at the point of the Big Bang itself. Was it the greatest black hole of all?
Was the Big Bang caused by a black hole that over ate, to put it simply? Do they have capacity limits? Can they become so dense that they can even absorb spacetime?

They know it wasn't that.

I don’t think they do. Anytime a singularity is reached in the maths of a theory, it means the theory has broken down. This is the case for both black holes and the Big Bang. Until the maths are sorted out I think any speculation is as valid as any other.

This is part of a conspiracy. A bunch of mischievous astrophysicists are planning a super scientific troll (targeting their observational astronomer padna's) to get somebody to use Black Hole and Uranus in the title of Scientific Journal Article.
Why the hell would we have left over singularities from the big bang hanging out around the Oort Cloud? That seems weird.

I thought about this some time ago and have come to believe it.

I think so. I think that is the origin of the Big Bang. So our universe would not be the first nor the last.

Not sure about this...perhaps. I think that maybe when a Black hole consumes enough (too much) matter it actually rips through space time to the other side (Big Bang). Everything starts over. The Universe initially expands as a result of the Bang. Over eons new black holes form, slowly eat worlds, merge, get larger, and eventually are strong enough to cause the Universe to contract back through the Singularity. BOOM! Start all over.

I think Black Holes leak ( via Hawking Radiation if nothing else ). A death scenario for a black hole is might involve it gobbling up everything nearby, then evaporating as all the incoming matter is depleted.
While their gravity does pull things in, to feed them, this nourishment brings angular momentum with it. Black Holes absorb this energy, powering their rotation which pushes things away from it at the same time. So, they don't absorb everything unchecked, or else we'd have no galaxies.
The path to prolonging their lives (Black Holes) lies in achieving unity. e.g.: our galaxy will merge with Andromeda eventually. What will really make the union official is when the event horizons of the Big Black Holes in the cores meet to form one giant-arse Black Hole. That combined singularity will outlive either Andromeda or Milky Way's holes would alone.

Never thought about that possibility. There would have to be a huge ripple throughout the cosmos if it happened.

I think it's funny they call it Planet Nine. I swear it's like they purposely downgraded Pluto for the sole purpose of not having to call it Planet 10(X).
Because them nutters have been claiming Planet X was out there for years along with a bunch of other stuff. I think they claimed it was a brown dwarf, but 5 times the earths mass doesn't fit that.
Never spent much time on the topic as they quickly start talking about aliens and shite, so I just tune them out. But it's kind of weird that I never heard anything real about an extra planet until years after they downgrade Pluto. Previously they always claimed the mass out there was just a bunch of small things.
I suppose a black hole would explain why they can't seem to find it. But even if it's not a black hole, shouldn't they be able to use the paths of things affected by it to find this like they do other black holes?
