Blackholes.
Black holes don’t suck.
Somewhere, something is waiting to be known!
Black holes are the strangest thing in existence. They don’t seem to make any sense at all. Where do they come from? And what happens if you fall into one?
Mathematically speaking anything in this universe or a multiverse(I believe in multiverse) could become a black hole. Yes, it’s true but highly theoretical.
Me, you,this device you reading on could turn into a black hole if we could compress it in a small enough space. Everything in this world has something called as Schwarzschild Radius.
Schwarzschild Radius
A tiny amount of space that, if you were to collapse the entire mass of the object into, it’s density would be so great that, it’s gravitational pull would be so great that not even light could escape from it.
Let’s make things interesting: The Earth would become a black hole if you would compress it into a size of a marble (approx 18mm).
Or
You could arrange so many earths together, so their mass would be great enough to become a black hole. So mathematically, the radius of all those earths put together, must be greater than the distance from the earth to sun.
Then you’ll have a black hole. :)
Author’s fact: Black holes don’t suck. This is a misconception. Planets can revolve around a black hole and still stay in orbit until the density of the black hole increases.
The depiction in movies about black holes are mostly wrong. They are not vacuum cleaners to suck things into them.
How does Black Hole look like?
So all black holes have a boundary or a Event Horizon.
Event Horizon:
If you looked at a black hole what you’d be seeing is the Event horizon. So anything that crosses the event horizon needs to be traveling faster than the speed of light. So in other words its impossible.
So we just see a black sphere reflecting nothing.
So if the event horizon is the “black” part in the “black hole” then what is the “hole” part of the “black hole”??
The “hole” part of the “black hole” is the Singularity.
Singularity
A Singularity may be infinitely dense,(i.e.) all its mass is concentrated in a single point with no surface or volume.
If I could explain it to you with Space time fabric (Einstein’s theory of relativity for finding black holes)
Think we have a towel suspended on its 4 corners and we place a ball of 10kgs on the towel.
We can see that the towel curves into the ball. So if we take a smaller ball, the curves would be less and a heavier ball, the curves would be more.
So it doesn’t matter how I get 10kgs there, but the curve of the towel remains the same amount. So if I were to take a different ball and crush it, so I make it way smaller and I still end up getting 10kgs, the curve would be the same and if I continued doing that until I get a ball of size smaller than a peanut which is so dense that it becomes a Singularity. And we still get the same curvature but the ball is so small you can’t even see it anymore.
So that’s really the idea of a black hole.
And what happens if you fall into one?
This is where things get really interesting and weird.
If we could get into a black hole, we have to travel faster than speed of light. Which as of (2019) is impossible.
(Any time travelers reading this post from the future please contact me)
If we would fall into a black hole by any mysterious miracle, we would be stretched like a spaghetti and would die.
(Scientists call this Spagettification).
More to be continued in the next post under Space.
Hope I wrote the post in the most simplest manner that I could write. I tried my best to make the concept of black holes simple enough so that even a person who doesn’t understand space could still get it.
I’m open for suggestions and corrections. :)
Physicists and Scientists of Space exploration out there reading this, I’m open for all corrections and your valuable suggestions.
Catch you next time.

Thanks for reading.
Until next time
Peace, Love and Gratitude.
