Is'PlanIset Nine 'Actually A Black Hole In The Solar System? There is only One Way To Fing Out
"planet nine" is considered unlikely to exist because it would be difficult for the solar system to collect enough materrial at such a distance from the sun to form a super Earth sized planet.Which hs led astronomers to think up some even crazierr ,thee observed "planet nine effect "could actually be.
How Close To Earth Is The Closest Black Hole?
Why do some think that planet nine could be a block hole?
"If it exists and is not a stastical fluke , 'planet nine' is most likely a planet , not a black hole , said lead author siraj in an email to me last eek .there is no unambiguous evidence showing that black hokes exist that are less massive than the about mass of the sun ."
Howeverr , another recent paper showed that the probability of the solar system capturing a free floating planer at the distance of planet nine could dbe compara
ble to the probability of gravitationally capturing a black hole with a similar mass.
To be clear , it probably is not black hole .
"No primordial black holes have been unambiguously delected ,and it is unclear exactly how they worth checking out . say siraj or perhaps to confirm it.
How to find planet nine or a black hole
The first very expensive , way to find a black hole in the solar system wold be send 100 specially -equipped spacecraft , as proposed by Edward written ,and scott Lawrence and zeeve Rogoszinski at the univesity of ,maryland , to search a vast area of space .Those spacecrafts high -precision atomic clocks would revral its presennce as they passed through the gravitional field of any plannet ninne or black hoke the tell tale sign being that they would speed up
However ,a recent paper by loeb showed that drag and magnetic noise from the interstellat medium would likely domunate over any gravitational signal from planet nine.
So we need another wy to figure out if planet nine is a black hole or not ,and that was the motivation for ny paperr says siraj and loebs paaperr ffocuses on the search for the occasionl flares of light that would naturally occur from collisions between oort cloud object and the black hokes , if it exists .
What is the rubin observatory?
The paper suggest ythat the Rubin obserrvatory --Which is now on an advanced statee of construction close to the Gemini south telescope ---- Will be able to confirm thee existance or nor of a black hople in thee solar sys tem .
The Rubin Observatory is all about wide-angle real time astronomy .Its 10 year Legacy Survely of a Space and time surely of thee sky evey threee nights with each image covering an areaa 40 times thee size of the full moon.
by both alerting astronomers to real -times event and constructing a massive data archive it is expected to dramaticaly advance astronomes knowledge of the cosmos.
