To determine

The three major ideas of astronomy that frame the context of the search for life in the universe.

Answer to Problem 1RQ

Life can be possible only when the basic requirements of the life are fulfilled on other planets.

Explanation of Solution

The three major ideas of astronomy that frame the context of the search for life in the universe are given below as.

  1. 1. The universe is vast and old:

In the universe, there are a number of planets or worlds in which life is possible. The universe has many galaxies like “Milky way”, planets, moons, stars, and a solar system. The age of the universe is 13.8 billion years old. At present, there are few planets where life is possible. The old age of the universe means it will take plenty of time to begin life.

  1. 2. The elements of life are widespread:

The observation of elements indicates the basic requirements of atmosphere that can make the life possible on the planet in a universe. It means life can also be possible on the other planets if the atmosphere is convenient for the growth of life on it.

  1. 3. The same physical laws that operate on Earth operate throughout the universe:

Some basic law’s which are valid on the earth surface they should also valid in the whole universe then only life can be possible on the other planets.

Conclusion:

Thus, life can be possible only when the basic requirements of the life are fulfilled on other planets.
