BLACK HOLES TRAGEDY
An imaginary image of black hole
Well if you are here to collect with some great stuff related to black holes, you are absolutely at the right place now as we are going to discuss about them in great detail. So lets begin with it:
WHAT IS A BLACK HOLE?
According to NASA, ‘ BLACK HOLES are those regions of space where gravity pulls so much that even light cannot escape out of it.’
I would give hundred on hundred to NASA as it is absolutely right but did you noticed that here gravity is ‘pulled’ so much. Now what does this really mean? Lets get an answer to this.
The answer is quite a complex one but don’t worry for I am here to make it simple for you. So if we want the gravitational force to increase for say a hollow sphere, we are required to add some amount of heaviness to it i.e. some amount of mass to it.
The mass would actually increase the density of the hollow sphere, as a result of which the F would increase. So the game here is simply of the density.
The black holes too are such sorts of objects.They are objects with an infinite density.
Now you must have got with another question that how is black hole infinitely dense?? The answer here is quite a simple one. So let’s discuss that within the formation section:
HOW ARE BLACK HOLES FORMED?
Well the phenomenon of the formation of a black hole is quite a complex process and a difficult one to understand but don’t worry I am here for making it tremendously simple for you.
So this beautiful phenomenon begins with the end. I know it would be quite confusing but it’s true as it’s formation begins with the end of a ‘massive’ star.
Here in the above image is a presentation of supernova explosion. Now you must be wondering on what a supernova explosion is? So I have linked the an article talking about it. You can probably visit there and I too would be writing a post over the topic. So make sure you have subscribed us for the notifications.
For now just imagine that it’s a type of explosion of all the atoms of star. Now just think of what would be the actual reason behind the explosion, it is of course the gravity. Most people would pretend gravity to be a force but it’s not actually the case. It’s just the curvature of space-time.
We would talk more on it in our upcoming posts. So this gravity is actually responsible for the explosion. Such time arrives only when the core of star can no longer oppose the higher gravitational force thus getting squeezed up into the size of about a point (accurately equal to or smaller than the Schwarzchild’s radius.)
And this happens in about one millionth of a second time. Thus all the mass of the star arranges itself in such a way that the density becomes infinite. (Infinite for we don’t know the actual thing). This point is known as point of singularity.
Singularity is a point from which no object in this universe even light cannot escape and where all laws of physics fail to describe any event.
So that was a simple version of formation of black hole. Now let’s talk on how black hole can be end to the universe.
The End Of Universe – Black Holes:
Well apart from all this, there are several theories that predicts that black holes are the end of this universe and entrace to the other and this is been predicted on the behalf that the density of black holes are infinite and it is also believed that the curvature of space-time is infinite.
So probably the black holes may make a hole in space-time thus joining two or more universe.
Now by not taking it too long, I would like to bind the article. I haven’t cover the types of black hole to maintain the glory of it as a blog. I will surely try to cover it some other day.
