New studies indicate that dark matter could gather in the heart of planets in Jupiter size over large periods of time and create black holes that eat these worlds from the inside. This striking concept can mean that extrasolar planets or “exoplanets” can be used to examine the secret of dark matter.
In this new model, super hinge particles of the dark matter were caught by exoplanets, losing energy and driving towards the core of this world. There these super -hinge particles of dark matter accumulate until they collapse and form a black hole. This black hole then eats its way out of his host planet.
However, this new theory for dark matter/black hole does not work with all the recipes of black holes. For example, when dark matter meet particles and destroy each other as some models suggest (how it happens when electrons meet their anti -particles, positrons), it would not be possible to collect in quantities to collapse and born a black hole.
Dark matter worries the scientists because despite the fact that they make up 85% of “things” in the universe, we have no idea what it is. The fact that dark matter does not interact with light means that it cannot be invented by the electrons, protons and neutrons that form the atoms that put together everything we see around us: the ordinary matter of the universe – stars, planets, moons, living things, etc. This puzzle has meant that scientists may suggest all types of different particles, which may be responsible, dark matter, of which have many different properties.
But the recipe for dark matter that is required for this process is still a restriction. The components should have very large masses. This excludes one of the most preferred candidate particles, the axion, a hypothetical particle with a very small mass.
“If the particles of dark matter are difficult enough and do not destroy them, they can finally collapse into a tiny black hole,” said Riverside researcher, multi -dad Phoroutan multiple, in one explanation. “If the particles of dark matter are difficult enough and do not destroy themselves, they can finally collapse into a tiny black hole.”
How are dark matter born black holes?
Currently the brightest black holes that we are aware of are so -called star crass black holes. It is believed that these masses have the sun mass between 3 and 100 times. The logic behind it is the sound because these black holes are born when massive stars no longer have nuclear fuel at the end of their lives. When a supernova explosion looks like the outer layers of this star, their star kernels collapse.
This means that the mass area of the black mass holes of star masses are determined by the masses of the forerunner stars they have generated. In addition, the lower mass is determined by the fact that stars with less than 1.4 times the sun (one known as the Chandrasekhar border) cannot go supernova, so no black hole or a neutron star can give birth. Instead, these stars leave a white dwarf.
There is also another mass limit. The Tolman -appenheimer -Volkoff (TOV) limit shares star nuclei that create black holes, and those who born neutron stars. Although less well defined than the Chandrasekhar border, the TOV border indicates that a star nucleus must have at least 2.2 to 2.9 times the sun after the largest part of its star core was expelled to form a black hole.
This limit is uncertain, since the brightest black hole that we have discovered and confirmed is currently 3.8 times the mass of the sun, while the heaviest neutron star, which has ever been recognized, weighs 2.4 solar masses.

These black holes of the planet, which are much smaller than the lightest black hole in the star mass, when they take on the mass of the planet that they devour. The team suggests that this process could occur within planets with masses such as Jupiter, which has about 0.001 times the sun.
“In gaseous exoplanets of different sizes, temperatures and density, black holes can form on observable time scales, which may even create several black holes in a single exoplanet,” said Phoroutan. “These results show how Exoplanet surveys can be used to search for exuberant particles with dark matter, especially in regions that are viewed richly as a rich in dark matter such as our galactic center of our Milky Way.”
Apart from the fact that a planet devour from the inside out, the creation path of the black mass holes and the TOV border means that recognizing a black hole with a mass that is less than the sun could support the theory of the team.
“A black hole with the mass of a planet would be a big breakthrough,” said Phoroutan. “If astronomers A discover a Population From black holes in planetary size, it could provide strong evidence of the Superheens not annihiling Dark Matter model. “

This new theory, combined with the growing catalog of exoplanet, with over 5,000 worlds beyond the solar system, means that these planets can now be added to the heavenly bodies that have been proposed as Dark Matt probes.
An example of this is the suggestion that certain candidates for dark matter could be caught in neutron stars, collect themselves and gradually destroy each other, causing these remnants to heat.
“So if we observed an old and cold neutron star, it could rule out certain properties of dark matter, since the dark matter is theoretically expected to heat it,” said Phoroutan.
Dark matter that is captured in exoplanets can also cause heating in these worlds, or it could cause them to emit high -energy radiation.
“Today’s instruments are not sensitive enough to recognize these signals. You may be able to pick up future telescopes and space missions,” concluded Phoroutan. “If we continue to collect more data and examine individual planets more precisely, exoplanets may offer decisive insights into the nature of dark matter.”
The team’s research was published on Wednesday (August 20) in the journal Physical Review D.. D.
