Last night I was laying in bed watching the stars and the night sky and I ask to my self, where the hell is my roof? No seriously, I just ate my last cookie and was sad because thing have to end, and I started to think, yeah a cookie doesn't las too long but what about big things, really big things, asteroids? How much time does a planet last? A Star?... OMG, WHAT ABOUT...

Let's start knowing a bit about these amazing and terrifying things, lets star simple, a black hole a point in space-time with infinite density (like your mum), this makes space itself distord in such a way that produces an incredible amont of gravity to be concentraded in one tiny spot, so much gravity that, nothing, yes NOTHING can scape, not even light and that is a serious statement because light is the fastest thing in the universe, this point where gravity is gathered is called singularity.

To understand this better imagine you have a giant blanket this will be your space-time, now lets add some weight and the blanket starts to bend a little, now lets crank it up to eleven and add a bunch of stuff, the weight will increase and the blanket will bend much more, it will be a point where the blanket will tear apart and this is your black hole, a point in your blanket where the weight is so extreme that its fabric can't take it anymore, so to summarize, a black hole is a point in space so dense it bugs the fabric of space and time, thanks black hole you broke the universe.

Not a Death Star, A Dead Star

Of course an object of such epic characteristics could only have an epic birth and because black holes are just like life itself (wonderful and terrifying at the same time), they spawn when a star dies, and it's a facinating process. First we have to find a star massive enough to do all the complicated physics envolved in the birth of our balck hole, we need a star at least 2.8 times more massive than our sun, that's because a star the size and mass of our sun can never go supernova (Hulk says: HAHA! Puny Sun!) which is the explotion that follows when the core of the star (that in a few words is just a massive fusion reactor) runs out of fuel and colapse on itself. I told you EPIC.

Now that we already made our star blow up, lets see what we got, If you can see a tiny bright spot dense and hot as my passion for pizza then you got a neutron star, this happens when all the mass of the former star is compressed to its minimum point, only the fundamental quantum forces of the neutrons prevent it from collapsing further into a singularity, but if we add more mass to our already massive experiment? Then no force in the universe will be able to stop it from collapsing, no force, not even Hulk (Hulk says: Hulk Sad =( ), the singularity is the final destiny of our star and a black hole has born.

EVERYTHING IS EXTREME!!!

When you can warp space-time and break it just with the gravity you produce everything you do is extreme, for example, we already know that not even light is fast enough to scape the gravitational pull of the black hole, but what happens you go near enough a black hole? Fisrt, you're going to experience a tremendous gravitational pull, you're gonna go faster and faster to its event horizon (that's the name of the actual black hole we can see), you'll get to a point were the gravitational pull you experience in your feet is stronger than what you feel in your head so you star to streach out longer and thinner in a process call Spaghettification... What are you laughing at? That's the actual name here look for yourselves. The tidal forces exerted by a black hole are so intense that can rip apart anything that comes too close to it, planets get swallowed, asteroids dissapear and stars are destroyed in a spectacular display of stellar fireworks.

But, does it die?

Well, yes but the end of a black hole is a complicated matter, we are now going deeper in the mechanics of the quantum world, that I'm going to dumb down a bit (A LOT) to better understand what happens. First, lets understand that empty space is just not empty space, there we can find interactions with quantum particles, in every point in space these virtual particles appear into existence, get attracted to each other an annihilate each other (freaky right), when we put black holes to the mix things get weirder, when this happens in the edge of the event horizon of the black hole one of those particles gets trapped in the black hole and the other scapes becoming a real particle, this makes the black hole loose energy in form of radiation, we call this Hawking's Radiation in honor of Stephen Hawking the physicist who discovered this process. However, this takes a very long time, the bigger balck holes we know will take a googol years to evaporate (That is 10^100 years, or to put it simpler 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years, yeah try to get your head wrap around that amount of time).

And that way the last thing existing in the universe fades out, with a radiation explotion in a very very very very very distant future, they go from epic explosive birth to extreme conditions with star destroying capabilities and end in a really procrastinated conclution, these masive objects make space and time warp and even physics gets weird around them, but the most important thing we learned is that if you get too close to a black hole you'll end up like this.

That wasn't what I meant but it's OK

P.D. I would like to dedicate this work to the memorie Stephen Hawking, which research made a lot of this post possible, thank you for everything great giant, we'll look forward for knowledge from the height of your shoulders.
