1. How is it that a star seldom finds another star near it?
It is very interesting and surprizing that a star seldom finds another star near it. There is a distance of millions of miles between one star and the other. The universe is so vast that they cannot hit one another. They continue their journey in loneliness.

2. What happened when, according to Sir James Jeans, a wandering star, wandering through space, came near the sun?
A star was wandering in the space blindly. A rare incident took place. By chance, it came near the sun. It raised tides on the surface of the sun. Then these tides formed a huge mountain on the surface of the sun. This mountain was unimaginable in size.

3. What happened when the wandering star came nearer and nearer?
When the wandering star came nearer and nearer the sun, the mountain on the surface of the sun rose higher and higher in size. It was, finally, exploded into pieces. This explosion took place due to powerful attraction between the sun and the wandering star.

4. What are planets and how did they come into existence?
Planets are heavenly bodies. They are broken pieces of the great mountain which was exploded on the surface of the sun. They came into existence due to this explosion. These pieces began to move round the sun ever since. Our earth is also one of them.

5. Why is there no life on the stars?
There is no life on the stars because they are extremely hot. They are a collection of fires. They have very harsh conditions. Life cannot exist on them. Life needs normal temperature that is not found on the stars.

6. Write a note on the beginning of life on the earth.
In course of time, one of the cooling pieces from the sun gave birth to life. We do not know how, when or why this happened. Life started in simple organisms. These organisms reproduced themselves before dying. Life became more and more complex . At last, it produced beings with feelings, ambitions, sense of beauty and religious beliefs. It is our guess that human race came into existence like this.

7. Why is the universe, of which our earth is a part, so frightening? Give as many reasons as you can.
The universe looks frightening because it is very great in size as compared to earth which looks like a small grain of sand. The universe looks frightening because of its immense distances.The universe looks frightening because of the unimaginable stretches of time. The universe looks frightening because of our extreme lonliness as there is no life on other parts of the universe.

8. What, in your opinion, should be the conditions necessary, for the kind of life we know to exist on other heavenly bodies? Do such conditions generally exist?
Life needs suitable physical conditions to exist. The most important of which is a temperature at which water could keep its liquid state. It should not be extremely hot or cold. Such conditions generally do not exist on any other part of the universe except on earth.
