Black Holes And Baby Universes and other essays


Mind is a marvellous thing. From the beginning of civilization, human has tried to know the mystery, miracles and destiny. His search is still going on. Is it going to end or is it never ending process? What is the origin of universe? What is its future? Is everything determined? There are thousands of question which stirs the mind with huge complexity and sometimes to think them; to understand them appears beyond our ability. But Stephen Hawking has made it an exception. His book “Black Holes and Baby Universes and other essays” has streamlined these complex issue in such a simple narrative format, with a stimulating wit   that even a non-scientific person can understand. The book is collection of essay that he wrote over the period 1976 to 1992, contains fourteen chapters, written in autographical way. The first few essay deals with his childhood, his studies in Oxford and Cambridge and how did he cope with his incurable disease precisely known as Motor Neuron Disease. His lines are motivating and encouraging. In one of his essay, he writes,” Before my condition was diagnosed, I had been very bored to life. There had seemed to be anything worth doing. But shortly after I came out of hospital, I dreamt that I was going to be executed. I suddenly realized that there were lot of worthwhile things I could do if I were reprieved.” There are other captivating moments like how he saw the boy, suffering with leukaemia and felt realized that there were people worse off than him. In the next chapters, he has dealt with public attitude towards science. About the conventional studies of science in schools, he writes, “Science, in schools, is often presented in dry and uninteresting manner. Children learnt it by rote to pass the examination, and they don’t see its relevance to the world around them.”
In further chapters, he explains what a complete and unified theory is and if there is such theory how we can model it. He says that modelling physical reality comprises two parts.
First we have to find the local laws that govern various physical quantities and second we should have sets of boundary conditions that tell us the state of some regions of the universe at a certain time and what effects propagates into it subsequently from the rest of the universe.
He further explains what the greatest mistake was made by Einstein(which Einstein himself accepted) and how he realized it.  A detailed discussion was made on the origin of universe, starting with different school of thoughts and then reaching to the modern concept of singularity that most of the scientists accept. He gives us optimistic thought of finding the one of the complex question,” How did the universe begin.” But why it bothers to exist, will be mystery.”
In the next chapters he explains the quantum mechanics of black holes, black holes and baby universe and rules out any possibility of space travel in near future due to uncertainty principle .In his essay entitled “Is everything determined?  He says,” yes, it is. But it might as well not be, because we can never know what is determined. “
About the future of universe, he lucidly explains the different possibility of universe in future. With a clear understanding of words like ‘chaos’, ‘singularity’, ‘critical density’, ’law of inflation’ he gives us insight that really  thrill us to catch a glimpse of dark mystery of universe.
 Read this book, you will as enjoy as you enjoy your favourite science fiction movie. You will never find such a simple book, without any equation (except E=m.c^2), on such a convoluted topic.

Women-Empowerment (A Short Story)

Her spectacle ridden red eyes were trying to run away from the crowd as soon as possible. Every person was looking so alien, so dreadful.  Her heart was pounding so fast, it felt it could come out anytime. She closed her eyes; took a long-breath; chanted a prayer, perhaps to stabilize her trembling soul. But it was of no use. In the high decibel of the noise she had already lost her ability to hear her own words. Somewhere at some meters away she found a corner.  She moved towards the corner with her shuddering legs but alas! Her blurring eyes were proving too difficult to keep open. She fell down and in a few hours she was laying against white bed-sheet in the government hospital. She didn’t know who took her there.  She moved her eyes everywhere to search some known faces. But there was no one. Finally she closed her eyes. So how are you feeling now? She heard a male, soothing yet concerned voice, but not sure if it was for her or someone else. She opened her eyes slightly...As the ima…

LAKSHMEE- A short story (Guest Post)

Many years have passed since she left this imperfect and unjust world, but still she floats around in my memories time to time. Today I have decided to tell the story of Lakshmee as was perceived through my eyes. Lakshmee was born as a first child in a family which had seen a girl child after two generations. Although a boy would have been more welcome in this case also, Her arrival in this world was tolerated or I dare say welcomed in much better way than many of other girls had in my village. At that time you could guess by the silence and gloom at home that a girls had arrived or by noise of celebration that a boy had been born. A feast was arranged as celebration for her birth which was generally reserved for boys. Her grandfather christened her Lakshmee, consoling his son that she will bring prosperity, material and money as well as many boys to family.
She was a very lovely child with plenty of smiles and comfortable with anyone wishing to carry her in his/her arms. Since she wa…

Begging Future

Scientists believe that after a certain period especially childhood, our mind does not develop; it just gathers knowledge, makes it experiences and learns new things.Freud, the father of psychology claims that till that age, the way our mind gets shaped; it lasts for our whole life and defines our behaviour and character. So, the important point which I want to draw is that childhood is the most crucial period which decides and defines our future.
To grow a child, is an art, the most beautiful living art of existence. But unfortunately, everyone doesn’t want to reveal his art as they have never felt the joy of this art Or maybe they would have work more prior to this. So their creation is not perfect. A child needs care, love, humbleness, spontaneity; which most of people would be mistaken by fulfilment of economic needs. Well, a good school can substitute the role of parents to an extent but not completely.
In case of India where good schools and perfect parents are a distant fantasy f…
