Black holes are, in many respects, the most extreme things in the Universe. They cram more mass into a smaller amount of space than anything else, bending the fabric of space so strongly that once something enters a given zone, it can never leave, even if it travels at the speed of light.
Each Milky Way-like galaxy in the Universe is believed to include millions, if not billions, of black holes, with the most large black holes reaching millions or possibly billions of mass of the sun.
There are just a handful known techniques to create a black hole in our current Universe. The core-collapse of an enormously large star is perhaps the most typical approach. The energy released by nuclear fusion in stars’ cores is the sole thing keeping them from collapsing due to gravitational collapse, since the outward radiation pressure balances the inward gravitational pull. That whenever a star’s core runs out of the fuel it’s burning, the radiation pressure falls, and the star’s core collapses due to gravity.
It gets hot when a star’s core contracts. It can start burning even heavier materials and use them as fuel if it gets hot enough. There’s nowhere else for it to go once it’s finished fusing elements like silicon, so the core explodes in a type II supernova explosion. By amassing so much material in such a small region of space, a black hole (rather than a neutron star) will arise if the star’s core is large enough.
If the combined mass of the post-merger object is larger than a specific threshold, you can create a black hole from the collision of two neutron stars.
Secondly, a black hole can develop by direct collapse, which occurs when a shrinking cloud of gas or a single massive star becomes too dense for light to escape from inside a given amount of space.
When you achieve that criteria, an event horizon arises, and anything that crosses it will not only never escape, but will also rapidly increase the mass — and hence the size — of your freshly formed black hole.
It can devour the whole mass of whatever item it came from in a matter of seconds, and you’ll have a black hole on your palms.
The most abundant sort of mass in our Universe is dark matter. All of the known, normal stuff in our Universe, including stars, planets, lifeforms, gas, dust, plasma, and more, would only account for around 15-to-17 percent of the total gravity we observe.
The remaining mass, which outclasses ordinary matter by a factor of 5, must be fully invisible, which means it doesn’t absorb or emit any light. Yet, in order to produce large-scale structure in the Universe and hold galaxies together, it must interact gravitationally. So why can’t it create black holes?
Dark matter can’t make black holes alone; it also can’t make dark matter stars, planets, or dark atoms. Consider the Universe in its infancy, before there were any black holes, stars, planets, or atoms.

Where Do Wormholes fit In?
Is that the case? Scientists have studied the notion that black holes might be wormholes to other galaxies for many years. They might even be a portal to another universe, as some have speculated.
Einstein collaborated with Nathan Rosen in 1935 to theorise bridges that connect two separate positions in space-time, and this notion has been floating around for a long time.
But in the 1980s, physicist Kip Thorne, one of the world’s foremost specialists on the astrophysical implications of Einstein’s general theory of relativity, sparked a debate regarding whether things could physically pass through them.
Perhaps Black Holes Don’t Go Anywhere.
Physicists Ahmed Almheiri, Donald Marolf, Joseph Polchinski, and James Sully, however, agreed Hawking was correct. They developed on a notion known as the AMPS firewall, sometimes known as the black hole firewall hypothesis.
Quantum physics might theoretically convert the event horizon into a massive wall of fire, causing anything that came into touch to instantly burn. Black holes, in this sense, lead nowhere since nothing can ever get inside.
This, on the other hand, goes against Einstein’s general theory of relativity. Because a thing would be in free fall and, based on the equivalence principle, that object or human would not feel the harsh effects of gravity, someone crossing the event boundary shouldn’t experience any significant suffering.
It may obey the rules of physics found elsewhere in the cosmos, but even if it didn’t contradict Einstein’s principle, it would cast doubt on quantum field theory and imply that information can be lost.

There might be stellar black holes produced from dark matter somewhere out there. Seriously. Though most people think of black holes as the superdense core of a dying star that collapses in on itself and devours anything that comes too close, astrophysicist Carlos R.
Argüelles and his team of researchers now have a hypothesis for how these monsters may develop from something much worse. They speculate that supermassive black holes hiding in galaxy cores may have grown abnormally quickly as a result of dark matter supercharging.
FAQ related to Can Dark Matter Collapse Into A Black Hole?
Q- Is it possible for dark matter to fall into a black hole?
Ans- According to this idea, the extreme gravity of some neutron stars would have continually drawn dark matter particles; ultimately, their gravity would have gotten so powerful that the neutron star and dark matter would have collided into a black hole, according to the new research.

Q- Is it possible that black holes can explain dark matter?
Ans- A few of the primary reasons why researchers are interested in these strange black holes is that they may hold the key to solving one of astronomy’ most persistent mysteries: the identification of dark matter.Because its magnetic effects can be observed all around the cosmos, physicists know dark matter exists even though they can’t see it.
