Black holes are one of the most fascinating objects in space. Dark, mysterious, sometimes portrayed as threatening… They’re the heartthrob in every astrophysicist’s wildest dreams.

A black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of a large metropolitan city. The resulting gravitational field is so strong that not even light can escape its pull.

Einstein envisioned them first. His theory of general relativity predicts that when a massive star dies, it leaves behind a small, dense remnant core. If the star core's mass is more than three times the mass of the Sun, the equations showed, the force of gravity overpowers all other forces and produces a black hole.

The Milky Way Galaxy – our home – could contain over one hundred million black holes. At the heart of the Milky Way lies a supermassive black hole – the infamous Sagittarius A*. The colossal structure is about 4 million times the mass of the sun and lies approximately 26,000 light-years away from Earth, according to a statement from NASA.

The discovery of neutron stars by Jocelyn Bell Burnell in 1967 sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality. The first black hole known was Cygnus X-1, identified by several researchers independently in 1971. It is located within the Cygnus constellation.

The first signs were discovered in 1964 when a sounding rocket detected celestial sources of X-rays. In 1971 astronomers discovered that the detected X-rays were coming from a bright blue star orbiting a dark object. The detected X-rays were supposedly a result of stellar material being stripped away from the star and consumed by the dark object.

Our supermassive black hole Sag A* in the center of our Milky Way

In May of 2022, the first image of the black hole in the middle of our Milky Way was taken, following the release of the first picture of a black hole in 2019. Although we cannot see the black hole itself, the glowing gas around it reveals a telltale signature: a dark central region (called a “shadow”) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun. It’s the first time there has been direct visual evidence of the Sagittarius A* black hole. The event Horizon Telescope created a single image by combining images extracted from the EHT observations. It was produced by averaging thousands of pictures using diverse computational methods all of which accurately fit the EHT data. This averaged image retains features more commonly seen in the varied images and suppresses features that appear infrequently.

Using this technology we can enrich our future research on black holes and perhaps discover new answers to the mysteries.

Well this is interesting but are you 100% for certain this is a black hole ? :neutral_face: after all here are some problems I have teach myself 1 you say over and over that NOTHING not even light can escape a black hole then why do every single galaxy we see light and not a black circle? :neutral_face: 2 how do you know that rather then a black hole it’s just empty space ? As I have learned that the physics of a hurricane look very similar to that of a galaxy and hurricanes have no black hole it’s just empty space :neutral_face: and number 3 what’s a black hole made from ? What ELEMENTS make a black hole 🧐? Those are some questions you have to answer :neutral_face: after all black holes may not even exist

Well many things are possible :neutral_face: however….theirs a difference between natural organic and man made :expressionless: natural means it’s NOT living and not made by humans or aliens :neutral_face: that’s what the universe is made from for and if something can NEVER be created naturally from the laws of nature and physics as if the universe was truly forever dead it means according to the laws of nature it’s 100% impossible :expressionless: as 0*0=0 or 1*0=0 :expressionless: even if is ♾ *0 the answer is still 0 :expressionless: and that’s only natural as or organic it means it’s made from nature HOWEVER…unlike the natural laws of the universe we can’t be dead and born the next :expressionless: but the universe can when a super nova happens it created new stars and planets but for us we won’t exist agian unlit the EXACT same planet is created :expressionless: as you melt a rock it becomes something different and that can have a HUGE impact how life is created :expressionless: however take a steep futher and you get man made this law means is NOT organic or natural the whole point of man made just means to manipulate the laws of nature :expressionless: as their are things that are possible but they can’t be created naturally they can only be a product from humans :expressionless: examples include cloneing , gene slicing , as even even elements and things we make can only be created in a lab witch is man made NOT natural :expressionless: Beacuse in nature they don’t exist :expressionless: but they can exist :neutral_face: and what I said will lead to a theory of everything as everything is connected in one way or another :neutral_face: the more thinking I do the more my brain hurts :expressionless: no matter how smart you are the human brain can not accept and understand very complicated things :expressionless: and based on what I have learned I would agree we live in a determined universe as the universe is all ready set in stone as the NATURAL physics are set :expressionless: think about it all of us will die the earth will be destroyed that seems like determinism not random :expressionless: as even people and animals that have yet to be born their fate is set in stone :expressionless: as being born just means they will die one way or another

Well I could say the same with you :neutral_face: as the human mind is prone to illusions as people only see what they want to believe :expressionless:

Well their is no believing in anything the truth is the truth while you understand it or not :expressionless: also if you reed I said it was a THEORY :neutral_face: as not even I know the truth about black holes but based on what I have teach myself i think they don’t exist :neutral_face: as I have realized the physics of a hurricane look similar to that of a galaxy :neutral_face: and if you were in the center their is no black hole :neutral_face: the winds are very calm :neutral_face: that could be the same with all galaxies as hurricanes fall into the same family as galaxies similar to apes and humans :neutral_face: their has to be a possible link between the 2
