Black Holes.
     - Written by Abdullah Al Faruque.
-----------------------------------
When a massive star dies, looses his stability,
By keeping pace with attraction race,
At the last stage, it becomes a black hole in space!
Nothing, not even light can escape from him!
Think about its Event Horizon Deeply, Don't be dim!
What strange thing is happening in there?
We hope, it'll so cool and fair!
Time becomes so slow to an observer,
Outside from the range of the mysterious border.
Do you know, it creates a beautiful space-time curvature?!
Every rotating galaxy has a Black Hole in its centre!
