15 Lines Knowledge : Black Hole
What is Black Hole And How do Black Hole form ?
_Black Hole is.........., We don't know either. We only know that Black Hole is form when the star with bigger mass than our Sun reach the end of their life, It's when the star can no longer withstand the Gravity of it own because it run of fuel, As the fuel has ran out it implodes and sucks the matter into it core and after that the big explosion begin we call it The SuperNova, As the result it creates a super dense Neutron Star or Black Hole depend on the Star mass.
Super Massive Black Hole
Black Hole know as the densest object in the universe, Everything cannot escape the black hole claw, By mean the gravity of black hole pulls the objects in when it pass the Event Horizon ( The Boundary Of No Return ). Nothing can get out of the event horizon unless they escape at speed faster than light, Which mean it won't possible.
Illustration of Space-Time Fabric around Black Hole
In addition, Most people mistakenly thought that black hole is shape like a funnel that sucks matter but actually it isn't. Black Hole is a sphere like thing just like Earth and other Star, But since we cannot see the black hole ( because it pulls the light around the region make it invisible to us ) Scientists have been using a space-time fabric to represent the black hole instead.
Event Horizon And Ergosphere
Although we have very little knowledge about the black hole, Scientists can detect the presence of it and study it by looking at the behavior of the objects such as Star or Disk of Gas nearby and we also hoping to learn more about it better in the future.
And you ask why are we studying them and is it going to benefit humankind ?
_ The answer is No, It doesn't have any benefit for us .
We study them because we're Curious
Science is love

We however know a lot on the theory side about black holes. They naturally arise from Einstein equations, as known from the mid-1910's. They are predictions of general relativity, and actually we have observed many black hole candidates so far. On top of this, we have the EHT telescope studying the BH lying at the center of our galaxy and trying to map what is going on there, and we cannot ignore the gravitational wave detection of last year that involved BH merging (this is a tleat the most plausible explanation of the observation).
So in short, saying that we do not know anything... is slightly misleading.
I understand but we're not sure what's going on around it and how physics work at the region.
all of the above is just my idea Thank you for the comment :D
We are not sure, but we have proposals, which I think is different from totally being in the dark :)
Yes :)
