Primordial black holes (PBHs) are old and relatively small black holes that emerged soon after the Big Bang. They are thought to have been formed as a result of density fluctuations in the very early universe. It is believed that PBHs with the lowest mass have likely evaporated. However, those with larger masses may still exist, evaporating at the present epocheven though they have been never directly observed.
Astronomers Jakub Scholtz of Durham University and James Unwin of University of Illinois at Chicago, assume that PBHs could reside even closer to us than we think. In a recently published paper, they ponder the possibility that the elusive Planet Nine, theorized to be orbiting the sun at a distance between 300 and 1,000 AU, could be such an old and compact black hole.
Explaining their intriguing hypothesis, the researchers focus on two unsolved gravitational anomalies of similar mass: anomalous orbits of trans-Neptunian objects (TNOs) and an excess in microlensing events. What is interesting is that both events are due to objects with masses estimated to be between 0.5 and 20 Earth masses.
The anomalies of TNO orbits are assumed to be triggered by a new gravitational source in the outer solar system. While it is widely accepted that this source could be a free-floating planet, Scholtz and Unwin argue that the PBH scenario is not unreasonable and should be taken into account.
However, it could be difficult to confirm this theory, as such a hypothetical PBH, with a mass of around five Earth masses and a radius of about five centimeters, would have a Hawking temperature of approximately 0.004 K, making it colder than the cosmic microwave background (CMB). Therefore, the power radiated by a typical PBH alone is minuscule, which makes it hard to detect.

“Your stupid minds! Stupid! Stupid!”—Eros
“The grief of his wife’s death
-became greater and greater agony.
-The home they had so long shared together,
became a tomb.
-A sweet memory of her joyous living.
-The sky to which she had once looked,
was now only a covering for her dead body.
-The ever-beautiful flowers she had
planted with her own hand,
-became nothing more than the
lost roses of her cheeks.”—Narrator

Can you prove that it didn’t happen ?”—Criswell
And who could argue with that?
A primordial black hole orbiting our sun would explain our suns missing companion star.
Most stars have a companion.
Well, in that case I volunteer to be Emily Blunt’s companion.
My friend, you have seen this incident based on sworn testimony.

Women and minorities hit hardest.
Send Pelousy, SorozNazi, and Romney into it to investigate!
They like to investigate ... they’ll enjoy it
Better work on your six pack then

“Primordial black hole”
OK, I haven’t read this yet, but if it has anything to do with Maxine Waters I’m hitting the abuse button.
“Therefore, the power radiated by a typical PBH alone is minuscule, which makes it hard to detect.”
Shoot a rocket with a transmitter at it, and see if it disappears when it gets to where the PBH is supposed to be?
There is a stranger possibility. String theory proposes 11 dimensions. Gravity is the weakest natural force because it extends into more dimensions than the electromagnetic force. Given this you could have a mass in one of those other dimensions influencing ours. In other words a ghost planet. Unlike a black hole you’d have a place of attraction but you’d have no problem moving through the center of mass. It would be as if you had a planet in place but the only thing experienced would be it’s gravitational pull.
Interesting.
If it were a companion star, then it would have about 2 solar masses and it would be the center of the solar system - which I doubt. In order for a stellar remnant to become a black hole, its mass has to be considerably above the Chandrasekhar Limit. Maybe 2 solar masses is the minimum. That would translate to an original mass of anywhere between 10 and 25 solar masses - a white or blue star, which would have a much shorter lifetime in the main sequence than our Class G yellow dwarf. Less than that, it turns into a neutron star. Ending up as a black hole or neutron star tends to be a very violent end, with a nebula being a calling card of such demise.
