What is a black hole in the sky and how does it formed?
There exists variant theories for the existence of Black Holes; one hypothesis has Black Holes being created from the collapsed stellar core of larger than three solar masses, while another has black holes predating stars and forming upon the instance of the Big Bang. In fact, the concept of a star growing or shrinking has little to do with gravitational accretion. So if a Black Hole is just a converted state of stellar evolution, then should we expect that the Black Hole size should be dependent on the amount of material being attracted and annihilated upon its Event Horizon? Per the current consensus, there is not a relevant relationship between the observable size of the accumulated bulge about the Black Hole and the size of the Black Hole itself.
And considering the Black Hole radiation jets act as the safety valve for the reactions within a Black Hole, one might speculate that, like a star, the size of the Black Hole has more to do with its internal reactions and less to do with the matter being converted upon its Event Horizon. Still another such theory has their formations predating galaxies and or even predating normal matter itself, existing unto the moment of the Big Bang itself (i.e. unfolding of SpaceTime into a traditional fourth dimensional condition).
Hole in the Sky is from the 1975 Sabotage album.
never because the sky is black and there is no light to see into the hole therefor they call it a black black hole
Whatever was in the spot in the sky that the black hole now occupies would no longer be there.
the fact that a black hole is formed when a star collapses, and a supernova is a star that collapses. the difference is that a black hole is formed when a star collapses completley
Black hole tunnel is formed by strong electromagnetic waves moving in a rythmic way.
A black hole does not create a star. A black hole is formed when a star dies.
The sun's energy has not formed a black hole.
The Black Hole will explode because the gravity of a Black Hole is formed by the matter that is in the process of going into the Black Hole, and not that matter that has already gone inside.
A black hole is formed when a star or other large body collapses on itself.
No, if it had been sucked into a black hole, it wouldn't still be there shining in the night sky.
You can't see them.
This is a black hole formed from antimatter, instead of matter. The only real difference thereby being that the matter within the black hole would have an opposite charge from normal matter. Other than that, an antimatter black hole, while still theoretical at this point, should have properties the same as a black hole formed from 'normal' matter. As with a normal black hole, an antimatter black hole would be created by having enough antimatter… Read More
a black hole is formed when a star dies (it explodes). sometimes it can also form a nebulae
A blackhole is formed in our universe when matter falls onto the black hole and that forms an accretion disk that is heated by friction. The black hole does not allow anything to escape it.
For a stellar black hole, yes. Mass cannot be created or destroyed. Generally a black hole will be less massive than the star from which it formed, as much of the star's mass gets blasted when the star dies in a supernova. A black hole can gain mass over time as matter falls into it.
A black hole could be. Light cannot escape and reflect into our eyes as it is sucked back in as the hole is a very dense object.
I dont know when it formed but i must tell you that 1400 years back eaarth has gone in the black hole just go through the holy book quran you will get to know everything.
no... A black hole is formed from an exploding star so unless you can control what stars do... then no.. im 12 and i know that....
Black holes refer to a dead star. When a star dies, its atoms are formed into a neutron star. When the neutron star is crushed, a black hole is formed. A black hole is a rip in space time. It sucks in planets, stars, and even light!
Well, obviously, if it formed a certain time ago. But I don't think you can tell the age of a black hole just by looking at it.
There is no "The" black hole. There are a huge number of black holes, but since black holes are occasionally formed by the death of suns most are far away. The closest black hole to Earth or Mars yet discovered is 1,600 light years from Earth.
You have to go through hole in the sky scrapper!
No, not even close! From what I understand, a Black Hole is formed when a Star dies and collapses into a small object. Exploding a mass into space will not create a black hole.
Nothing different than when matter enters, in fact there is no way to tell whether a black hole was formed from matter or antimatter. Once inside the black hole, if matter and antimatter react to make energy, that energy can't escape the black hole either.
No one knows how the FIRST black hole came to be; it happened long before humans roamed the Earth, long before the Earth formed, before the Sun was born. Black holes were probably formed in the titanic explosions of the supernova of massive stars.
A Black hole is a region in space where the pulling of gravity is so strong that even light cannot escape. This strong gravity occours because a very large amount of matter is compressed into a very tiny space. A black hole is formed due to uncontrolled contraction of heavy neutron stars under their own gravity.
Only in that they where formed by the same process. A neutron star formed from a star with less mass than a black hole
No, water cannot form a black hole, no matter the quantity. Black holes are only formed after the collapse of a supergiant star.
Hawking radiation describes how radiation is emitted from a black hole due to quantum effects. According to Hawking matter and ant-matter is formed simultaneously near a black hole an are destroyed as soon as they are formed. But sometimes one of these duo are pulled away by the black hole's gravitational effects and leaving a room for the other to escape. So according to this a black hole should be shinning instead of being black.
No, Because the earth is not a star and wont turn into a supernova Black holes only happen if a supernova explodes and when the sun a.k.a supernova explodes a black hole will be formed and all existence near the Black hole WILL disintegrate into tiny pieces of matter after entering the Black Hole because of the intense pull of the gravitational field.
Depending on the size of the star: a neutron star or a black hole-
a black hole
If you believe in God and you believe that God created everything, then sure. If you believe in science, then a black hole is created when a massive star collapses and a black hole is formed. [See related question]
no yes. a black hole is true because on the news it said TODAY A BLACK HOLE COULD APPEAR IN THE SKY BECAUSE OF SCIENTISTS TESTING THEIR NEW INVENTION. THE EARTH COULD BE SUCKED UP AND NEVER SEEN AGAIN. if that answers your question say tar.... BII
Chuck Norris roundhouse kicked a giant pile of rocks, which turned into a black hole. He then killed the black hole with his fists. The dead black hole then descended on earth and formed what we call now "Switzerland". Thank you, you useless dickweed
Obviously, there are many theories of how the universe formed, but personally, the universe formed from the result of a black hole, that sucks in matter, and that matter has to empty out somewhere, and it does, as a "white" hole, and that explosion is known as "The Big Bang".
It could become a black hole or a neutron star.
Nebula. according to nasa.
A Black Hole is not actually a hole in space and time, as some believe. It is in fact a planet with such a gravitational pull that it actually implodes in on itself. (Opposite of explode) Things that get pulled into these are destroyed and become part of the mass of the planet (Black Hole) So when things go "into a black hole" they go into or on the planet. ANS2: A black hole is… Read More
The milky way was formed by stars gases and dust . The milky way also started as a black hole and stars dust and gases gathered around the black hole.
A black hole is formed during a supernova (when a red giant star explodes)--the star collapses in on itself and creates a black hole. Then the black hole can move around or stay in one spot. They suck in everything around them (stars, planets, ect.) There is one black hole in the center of every galaxy. When two black holes come in contact, they create blue and red colors (one black hole is blue and… Read More
A nebulae can only die if it's right by a black hole or if all the stars that can be formed are formed which uses up the nebulae
A supermassive black hole is a an extremely large black hole, in the order of possibly billions of solar masses. They are thought to have formed from stellar black holes that managed to absorb enough mass from other objects, even other black holes and that they, without outside forces, can go on forever because they're so large that they absorb enough background radiation to compensate for the mass lost from radiating Hawking radiation. It is… Read More
The theory of a black hole and galaxies is that a black hole created a galaxy or was formed by a galaxy, if that makes sense. Eventually, our solar system will get sucked in. But this will happen in about over a billion years! add. For such a size of black hole, the timescale would be in the billions of years. But before which our Sun would have overwhelmed our Earth in its Red Giant… Read More
its original mass when it formed
The galaxy was formed from the attraction of stars which in our galaxy orbit a massive black hole.
A black hole is formed and no temperature exists
Sorry, you missed it by about 13 billion years. It already formed at the center of the galaxy.
