Scientists are now trying to figure out if grapefruit-sized blackhole actually lurk on fringes of our outer Solar System. In last few years, researchers have noticed odd clustering of multiple trans-Neptunian objects, which are found in far outer Solar System. According to report by Space. Com, some scientists believe that TNOs' paths have been sculpted by gravitational pull of big object which is five to 10 times bigger than Earth. While object could be Planet Nine or Planet X, there are theories that it could, in fact, be black hole that packs in all its mass into sphere which is roughly size of grapefruit. Study Has Been Conducted By Dr Avi Loeb, Professor Of Science At Harvard, And Amir Siraj, Harvard Undergraduate Student. Paper Has Been Published By Astrophysical Journal Letters. According to report in Universe Today, study authors have suggested that primordial black hole could be lurking in region. Unlike stellar black holes and black holes, primordial black holes are much smaller and form after Big Bang due to density fluctuations. In vicinity of black hole, small bodies that approach it will melt as result of heating from background accretion of gas from interstellar medium onto black hole, " Siraj said in statement. Once they small bodies are subject to tidal disruption by black hole, followed by accretion from tidally disrupted body onto black hole. Loeb add, because black holes are intrinsically dark, radiation that matter emits on its way to mouth of black hole is our only way to illuminate this dark environment. Loeb add, because black holes are intrinsically dark, radiation that matter emits on its way to mouth of black hole is our only way to illuminate this dark environment. They have found new way to search for black holes in outer Solar System-by studying flares that result from comets that are captured by black hole. According to researchers, data from upcoming Telescope Legacy Survey of Space and Time should be able to confirm or rule out Planet-Nine-is-ablack-hole hypothesis within year of Survey's commencement. LSST is expected to have sensitivity required to detect accretion flares, while current technology isnt able to do so without guidance. LSST has wide field of view, covering entire sky again and again, and searching for transient flares, said Loeb. Siraj added other telescopes are good at pointing at known targets but we do not know where to look for Planet Nine. We only know broad region in which it may reside. LSST's ability to survey sky twice per week is extremely valuable. In addition, its unprecedented depth will allow for detection of flares from relatively small impactors, which are more frequent than large ones.

Primordial black holes are different

Astrophysicists have suggested that hypothetical Planet Nine could be tiny black hole, and theyve proposed way to find out. Planet Nine has never seen directly. But existence of ninth Planet orbiting our Sun could explain certain features of outer Solar System, such as clustering together of icy rocks called trans-Neptunian objects with similarly tilt orbits. Last year, scientists in UK and US suggested that Planet Nine, which is also known as Nibiru, could instead be primordial black hole. These as-yet-unseen black holes are thought to have formed in fraction of second after Big Bang. If Planet Nine was such entity, it would be about size of grapefruit, with mass of five to ten times that of Earth. Now, two astrophysicists at Harvard University, US, have suggested way to investigate this: look for bursts of electromagnetic radiation, or accretion flares, that would be produced as this black hole rips apart and swallows any nearby icy objects. Authors propose using upcoming Legacy Survey of Space and Time to look for accretion flares. LSST will use 3. 2-gigapixel camera at Chiles Rubin Observatory to photograph entire visible sky every few nights for 10 years. LSST has wide field of view, covering entire sky again and again, and searching for transient flares, said study co-author Prof Avi Loeb. Other telescopes are good pointing at known target, but we do not know exactly where to look for Planet Nine. We only know broad region in which it may reside. Outskirts of Solar System our backyard, add Loeb. Finding Planet Nine is like discovering cousin living in shed behind your home you never knew about.

Black holes bending light

However, there's some recent evidence to suggest they might really exist, Unwin say. I think this is fairly unknown-about in community, Unwin say, and we're really trying to bring it to wide attention. There's experiment called Optical Gravitational Experiment in Poland. It scans sky for evidence of Gravitational microlensing, places in space where planet or some other object's gravity has bent path of ray of light, causing it to hit Earth. In cases of stars studied by OGLE, this light-bending just like star momentarily brightening. But OGLE reported something strange, they say. Six times, it has spot very brief microlensing less than 0. 3 days long, suggestive of very fast-moving between 0. 5 Eart and 20 Earth masses zipping past stars. This isn't how planets look to OGLE, Unwin say, and there's good to suspect that six objects might be primordial black holes. If those six objects were small, ancient black holes, Scholtz say, then that means such black holes aren't so rare in Universe. You wouldn't expect them to show in every Star System, he say. And most would float through space. But it wouldn't be terribly shocking if our system got lucky and one up, he say. Planet 9-black hole theory then explains two mysteries: trans-Neptunian object anomaly and OGLE anomaly. These two things at same mass range, Unwin say. This is thing that us quite excite. That's key thing, Scholtz add. Missing Planet is somewhere between maybe five and Earth masses, and OGLE evidence points somewhere between 0. 5 and 20 Eart masses. So this is quite coincidence. If TNO anomaly does actually turns out to be black hole, Unwin say, that's huge deal. It would prove existence of primordial black holes, and nail down mass range for them. That would explain when exactly in history of Universe they form-which would then explain how great many other bits of Physics come into being. Does that mean either researcher is convinced that there's black hole our Solar System, or even thinks there's probably one out there? No, they both say. It's possible that TNO anomaly doesn't really point to single heavy object, or that OGLE anomaly is fluke, or result of faulty equipment.
