There are many people that have a knack for words and many of these people are capable of writing science fiction books. In order to create an interesting story one must begin with a general topic. In addition, you also need to have a good understanding of science and to build up your knowledge it is recommended that you read books and articles as well as magazines and furthermore you should make it a point to speak to people who are inclined to reading scientific subjects.
Once you have gotten your general topic sorted out and once you are sure that you are knowledgeable about this subject you can then start writing down the draft of the book. You should there before start making notes about interesting things and then you have to pick a suitable topic which you are confident you can write about.
One of the questions that you will need to find a suitable answer for is that of what if. When writing fiction and that too on scientific subjects you will find that it will open up many horizons and if you are not able to keep these in check things can become very crazy for you.
You need to think up something special and when it concerns a what if scenario you should give your imagination a free run. For example, you should think about writing situations in which humans become capable of cloning themselves.
Once you have decided on a particular story line it is then up to you to decide on a suitable conflict. The simplest conflict topic is that of man going up against technology or even man versus man. Aliens will obviously play a very important role in these stories and will obviously be the villains of the story. Technology will have to be used by humans to ward off alien attacks.
At the very least, when it comes to creating a story one must not be afraid of stepping out of the box and being as original as possible. Once this is taken care of it is up to you to pick a suitable time period and you must also pick a suitable setting for your story.
A majority of these stories are those that take place in a time period that is not too far ahead of the present times. Also, these stories go beyond simply talking about our planet as there is scope for using other sciences that can be incorporated into the story. However, once a time period has been set then it is important that the story is one that stays within the limits of this time period.
The next step is that of choosing characters for the story and then you can begin with the main outline of the story. After that, it is just a question of writing all the required chapters.
Last but not least, when writing science fiction books you will want to know the difference between writing on fantasy and on science fiction. The latter is about occurrences that are scientific in nature and the former kind is about events that are not really going to happen in our existing world.
