Q.9:- Write in about 1000 words a fiction piece based on your speculation on the science and technology of the twenty-second century.

 

Answer:



These days, we go to distant places by means of a car or an aircraft fuelled by petrol. In the twenty-second century, we may plan for a journey to a distant star located hundreds of light years away from the earth by means of a spaceship, without taking care of any fuel needs. The spaceship is sent into space by firing a rocket engine from a launching pad. As it enters the region of magnetic field in space, it is propelled by electricity generated due to electromagnetic induction. The current induced is fed to the electric motors via superconducting wires. This avoids wastage of electric energy in the form of heat. Now suppose the spaceship enters a region in space where the temperature is very high. The connecting wires at once lose the superconducting properties. This may cause a panic in the spaceship as no power is available. Another spaceship containing both matter and antimatter in separate chambers may come to its rescue. Hence the spaceship may continue its journey to distant star without bothering about any fuel crisis.
