Okay,
Here we go.
Trees are green and we have a cellphone tower in the back of our office.
I am sitting in the office trying to write something and learn to type at the same time.
Wanted to learn typing since I've known any computer, that's around when I'm in 8th class.
No idea what to write so I opened my mobile and opened my music player Saavn and the songs are playing.
Still no idea what to write, but got my songs playing so somewhat better than the line before.
Read the lines so far I've written and wow it's close to five lines.
My girlfriend just texted me and I'm replying her. I have to reply in less time because I don't know what I did but I'm walking on egg shells around her now. I hope to get out of it soon.
Seems like nothing in my head worth putting in here. Really after all I've studied.
Of course everything I read is not general topics so not possible to reproduce them here.
Okay, off the top of my head I could write about black holes.


Between us, I think of myself as the black hole nerd. I like them. Don't know why, considering they are very dangerous. May be because I know they are very less likely to happen around us.
Interesting thing about it is many would say time seems to run slow when we're going nearer to it and stands still when we're past a certain place called the "Event horizon". Don't want to bore you with the details of Event horizon (E.H.) and the Singularity. Think of  E.H. as the border up-till we can see the happening of events. And beyond that we cannot see the events happening.
Let me give you an example.
What if I say that everything we see is into the past. Everybody knows how we see things right !!!
The light gets reflected after projected on to certain object that we want to see and we get to see it then. Because the speed of light is very fast (2.99 times 10 powered 8 metres per second) we tend to ignore that fraction of a second past and we project it as present.
For example the time it takes light to travel from sun to earth is around 8 minutes we always see sun to the past with 8 minutes. And the stars that we see at night are the past with respect to their distance to us.
So, now coming in the main line E.H.
Like I said, we cannot see the events happening past the event horizon because there is no reflection of light coming from there which is the main reason for us to see anything.
So this is what a black hole does, It won't let anything escape from it's core. Well that's the same that all the other planets and stars does, they won't let anything escape from them either. But there's a certain velocity (or speed) for each of these stars and planets. It's called the escape velocity. Don't want to bore you with the details of the equations. For example like for earth it's 11.2 km/sec. If you can throw an object that have a velocity of that much or higher, congrats you just launched something into space. But good luck achieving that speed. People burn off millions if not billions to get that speed with rockets launchers. A black hole also has a certain velocity that an abject can escape from it's core. But we don't know the velocity because the only thing that can travel faster is light up-till now and it can't escape from the core. It means the escape velocity is more than the speed of light and we have no way to find out what it's value is.
So, that's why we don't know what happens after the event horizon and also why it looks so black and dark.
That's it for today.
Next time may be we'll learn how it effects TIME.
