A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it's completely black, and hence it's called a black hole. A black hole's “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light.
When a massive star dies, it leaves a small but dense remnant core in its wake. If the mass of the core if more than around 3 times the mass of the sun, the force of gravity overwhelms all other forces and a black hole is formed.
A black hole is not just empty space; in fact, it’s a great deal of amount packed into a very small area. Think of a star which is 10 times more massive than our is squeezed into a sphere which has the diameter equal to the size of New York city. The result will be a celestial object whose gravitational field is so strong that nothing, not even light, can escape it. This is why black holes are named so, because they are pitch black!
"Black holes explained" is a short-animated video explaining the science of ‘what is a black hole’ and ‘how black holes are formed’? The "black hole picture 2019" is a recent event that occurred in April 2019, which involved the release of the first ever black hole picture to the general public. But what are black holes? How are black holes formed? What’s the explanation behind the black hole theory?

@@willyamcarkey717 you sound angry. Why so angry that I point out simple facts. I think it's silly to pay billions of dollars for a compilation pic that not only isn't accurate or a real picture. But it's just an attempt using mathematical probabilities to acquire more funding. This is about money, not science. I love physics and real science. Just not a fan of billions spent on theories and mathematical possibilities. Sorry. But the picture is a joke. Still waiting for you to produce these so called 2 "real" pictures. Next thing you'll be trying to convince me theyve defined gravity as well🙃

What if the whole reason why we can’t see light pass the event horizon on a black hole is there is a point at which the speed of a photon is so fast that it “teleports” from one point to another in an elliptical manor of orbit due to the intense gravity of the object aka black hole. Meaning, once an object gains so much mass that a threshold that gets passed where its gravity is strong enough to teleport the photon so fast from point a to point b that we just can’t see it physically speaking as it travels it’s orbit around the black hole. That’s why some of these black holes have rings of light on them emulating from the elliptical orbit of these photons . Photons that we thought couldn’t be manipulated by gravity to such great measures. Then say a dying star crushes down these atoms into new elements that we have never seen before because of the immense pressures. Something that can be super super condensed and small, giving a massive weight and gravitational pull to an object even though it is much smaller than other objects, its size. That's why when things hit their event horizon, it rips apart because the gravitational pool is so strong it rips things down to even smaller atoms and molecules and condenses them once at its center point. I dunno a better way to explain it but it’s worth a thought.

They are in plain English remnant fuel holes that used to be stars.. they’ve now collapsed, and become a liquid. Change of state happens when the hole grabs a nearby star and eats it.. the star will give off its heat load to the hole.. thermodynamics, and the gas will then liquify and enter the hole becoming part of its total mass

If it has an infinite density? Why does it get bigger????????? See what I mean? Doesn’t make sense.. now.. if the hole is a liquid then it makes sense because a burning gas will spin around the hole in orbit because if displacement.. a burning gas will loose heat to a cool liquid (black holes) and then enter once homeostasis is reached

@@yasglas right exactly. My contention is that we’ve been wrong all along.. thermodynamics speaks for it.. if the hole is a collapsed star remnant? Then it must leave behind some kind of mass? That mass even if it were solid iron would melt and liquify under immense gravity? Ok, so liquid black holes? Yup! Change of state when they go super nova and condense..

@@JKDVIPER it be a little hard to think of the singularity in a liquid State of some sort . I just think that it's gravity well is so extreme that any guess after the horizon could be correct I love the mystery of it. But the hot gases circling around it is due to friction just before going in

Are black holes fact or imagination? Heat waves are factual. Are gravitational waves heat waves? If not what are they? Cold is a repellant of heat. Heat is a propellant of resistance to cold. Atmospheres have violent reactions between the cold and heat. Theoretically space would have similar physical reactions to heat and cold, right. Thermodynamics is an outward force of pressure repelled by cold resistance throughout space, in and out of masses occupational area of space. Wouldn't space have to collapse to compress Thermodynamics into a pinpoint? If cold space is a field of cold resistance to heat. Then motion has to cycle to produce mass. Amassed Thermodynamics variations affecting elements. The greater the area amassed the more resistance contained in forced outward pressure of weight as heat. Magnetic fields of forced motion holding mass together are weaker Gravitational fields of forced motion holding mass together. Singularity is, each product of mass held together by gravitational fields of forced motion holding mass together as a individual units. Amassed Thermodynamics gravitational fields of separation from other gravitational fields of forced flow. Singularity of separation between forces by gravitational fields of forced flow. Each with its unique values of forced pressure known as weight. Weight as outward pressure held in mass by gravitational fields of forced motion holding mass together in singularity. Thermodynamics is the variant that defines gravitational fields abilities to hold or break gravitational fields. Magnetic fields are weaker Gravitational fields, but work similarly, to stronger Gravitational fields. Resistance to momentum forces the field to cycle in on itself as mass is occupational space, and is the weakest point of resistance. Proximity mass can disrupt this cycle or join it in equalization to resistance of space. Gravitational fields of forced motion cycling through mass in equalization of resistance. Occupational space is the weakest point of resistance. Newtons apple travels to the weakest point of resistance. The apple is a singularity and has its own gravitational fields of forced motion holding mass together. Resistance passes through mass as mass travels through space. Resistance is cycling from momentum of Planets traveling through space. If space is a stationary cold field of resistance to heat. Heat is then a propellant and gravitational fields are cycling patterns of forced motion holding mass together. The earths momentum is in forward resistance as resistance passes through the planet it repels the magnetic field backward to cycle through the atmosphere back towards resistance from behind, and is repelled by unoccupied space forward through the planets core of least resistance. Newtons apple, travels on the surface of the planet, no longer able to maintain its gravitational fields of forced outward pressure is stripped of its mass by resistance traveling through it as the planets momentum continues. The apples gravitational fields of forced motion holding mass together stripping down as decay or age. Each singularity of cells decaying to basic elements of gravitational fields of forced motion holding mass together. Thermodynamics. Loss of thermodynamics needed to resist cold is the beginning of decay. Age. Time is measuring decay. Loss of gravitational fields of forced motion holding mass together. Time is a tool. Thermodynamics can increase decay, and cold an slow it down. Time is a factor involving temperatures. Temperatures decrease or increase, decay of gravitational fields of forced motion, holding mass together. Even in the coldest point of space heat exists. Frozen means less thermodynamics than cold resistance. But still in equalization. Motion is heat repelled by cold resistance. Theoretically. Darkness is heat not in entanglement resistance. Free-flowing spacemotion. Entanglement is amassed heat in gravitational fields of forced flow.

Super nova happens on "smaller" stars where the gravity forces isn't enough to collapse but the spent fuel rebounds off of what it can't fuse any more. During the super nova explosion 💥 heavy elements are produced

@@yasglas yes exactly.. he calls it EVAPORATION because these holes are no more dense than water.. popular belief used to be, that we didn’t understand how these small holes could eat giant (we thought) stars. When in actuality, the black holes had been eating the whole time and gained massive gravities. Only problem is. The food is gas? It’s on fire? (Fusion) reactions in the cores of these stars go out.. we loose heat and matter changes state. The star spins around the hole cuz the hole is quite cool when compared to these stars in fusion reactions. So the cooling star matter makes its way into the hole once they’ve cooled enough. Explains why Sagittarius a is so stable. No food
