Solution
The development on the front of genetic engineering and biotechnology will include:
- Production of man, animals and plants with specific characteristics.
- High yielding variety of plants and specific crops would be sown.
Multiple use of laser in various fields or even more developed device which will transform the world. Man would treat himself as the king of universe.
Man may travel in space with unthinkable speeds and transportation would be totally revolutionised.
Man would travel deeper into the space and may settle on other planets, befriend strange creatures from other worlds or may wage a war with them.
In the field of communication, 22nd century has many surprises in store. Two persons sitting on the globe or on moon would talk on phone face to face.
Man may partially conquer diseases and slow down ageing.

The metre is defined as the distance travelled by light in `1/(299,792,458)` second. Why didn't people choose some easier number such as `1/(300,000,000)` second? Why not 1 second?
Suppose you are told that the linear size of everything in the universe has been doubled overnight. Can you test this statement by measuring sizes with a metre stick? Can you test it by using the fact that the speed of light is a universal constant and has not changed? What will happen if all the clocks in the universe also start running at half the speed?
Suggest a way to measure the distance between the sun and the moon.
