Answer the following questions:

Q1. How is it that a star seldom finds another star near it?

According to the author, several stars move in space and there is millions of distance between these stars. They travel in complete loneliness likes ship in an empty ocean. This is the reason while moving through space, a star seldom finds another star near it.

Q2. What happened when, according to Sir James Jeans, a wandering star, wandering through space, came near the sun?

Q3. What happened when the wandering star came nearer and nearer?

Q4. What are the planets and how did they come into existence?

The author believes, a wandering star, wandering through space, happened to come near the sun. Because a strong gravitational pull, huge tides were produced on the surface of the sun. The same pieces, in the shape of planets, started revolving around the sun. These were our planets and the Earth is one of them.

Q5. Life does not exist on most of the stars. Why?

According to the author, stars are like a collection of fires in space. There is thousands of degrees’ temperature on them. Away from these stars, there is cold of hundreds of degrees. So outside them, life would be frozen.

Q6. Write a note on the beginning of life on the earth.

According to the author, the earliest living organisms were very small, i.e. unicellular. They had the ability to multiply before death. By this, a stream of life was produced which ultimately gave rise to present living organisms.

Q7. Why is the universe, of which our earth is a part, so frightening? Give as many reasons as you can?

According to Sir James Jeans, the universe is frightening because of its immense distances, because of extreme stretches of time, our extreme. This feeling of the littleness of our planet also makes us frightened.

Q8. 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?

There are many solid reasons like Air, water, and moderate temperature are necessary for life. Most of the stars are not present in an ideal temperature belt. So, outside these temperatures belts, there is a very rare chance of human life.

Q9. What do you understand by absolute zero?

Absolute is 484 degrees of Frost on the Fahrenheit scale. It is the temperature before reaching which all the gases and liquids lose complete temperature and change into solids.

In Q9 absolute zero equals to 0 kelvin and -460F.
