Synthesized answer
According to the passages, the "first step" in scientific inquiry regarding the universe's grand questions is characterized by the use of scientific methods and instruments to attack problems that were previously only considered from an imaginative or speculative point of view [1][4]. This step involves employing instruments of "incredible refinement and exactitude" and the "full resources of mathematical genius" [2]. Specifically, the spectroscope has enabled astronomers to determine the composition of the sun and stars, measure their velocities, and even work out the main lines of stellar evolution [2][3]. However, the author notes that we have "scarcely taken more than the first step toward the actual solution" of these problems [1].
The passages do not explicitly describe how future, more advanced steps would differ in their approach. They do state that many questions "have not yet passed the controversial stage" and that "out of these will emerge the astronomy of the future" [5], implying that future steps will resolve current controversies. The text also suggests that the spectroscope's answers "open up questions of yet greater interest" [3], indicating that future steps…

From the book
ivilisation. Before our time the problem could be considered only from the imaginative or the speculative point of view. Although we can to-day attack it to a limited extent by scientific methods, it must be admitted that we have scarcely taken more than the first step toward the actual solution.... What is the duration of the universe in time? Is it fitted to last for ever in its present form, or does it contain within itself the seeds of dissolution? Must it, in the course of time, in we know not how many millions of ages, be transformed into something very different from what it now is?…
. It is to this wonderful instrument that we owe our knowledge of the composition of the sun and stars, as we shall see. "That the spectroscope will detect the millionth of a milligram of matter, and on that account has discovered new elements, commands our admiration; but when we find in addition that it will detect the nature of forms of matter trillions of miles away, and moreover, that it will measure the velocities with which these forms of matter are moving with an absurdly small per cent. of possible error, we can easily acquiesce in the statement that it is the greatest instrument…
? And the Sun itself, what is its composition, what is the source of its heat, how did it originate? Is it running down? These last questions introduce us to a branch of astronomy which is concerned with the physical constitution of the stars, a study which, not so very many years ago, may well have appeared inconceivable. But the spectroscope enables us to answer even these questions, and the answer opens up questions of yet greater interest. We find that the stars can be arranged in an order of development--that there are stars at all stages of their life-history. The main lines of the…

The picture of the Universe which the astronomer offers to us is imperfect; the lines he traces are often faint and uncertain. There are many problems which have been solved, there are just as many about which there is doubt, and notwithstanding our great increase in knowledge, there remain just as many which are…
ny of these questions have not yet passed the controversial stage; out of these will emerge the astronomy of the future. But we have seen enough to convince us that, whatever advances the future holds in store, the science of the heavens constitutes one of the most important stones in the wonderful fabric of human knowledge. ASTRONOMICAL INSTRUMENTS Sec. 1 The Telescope The instruments used in modern astronomy are amongst the finest triumphs of mechanical skill in the world. In a great modern observatory the different instruments are to be counted by the score, but there are two which stand…
More questions about this book
- The text states that astronomy's picture of the Universe is "imperfect" and "uncertain." How would you explain to a curious non-scientist *why* this is the case, considering the advancements of science, and what fundamental challenges does this inherently present to astronomers?
- Simon Newcomb calls the "structure and duration of the universe" the "most far-reaching" problem. If you had to explain to someone *why* understanding the universe's ultimate fate and design is considered more significant than other astronomical discoveries, what core ideas would you emphasize from this excerpt?
- How does the question of whether "the stars form a system" directly influence the conclusion about the universe's "duration" and potential for "dissolution" or "transformation," as presented in the text? Could you articulate the logical connection between these two ideas for someone unfamiliar with astrophysics?
- The text describes the planets as "a sort of colony of which the Earth is a member." What distinct insights or implications does this particular metaphor, "colony," offer about the solar system's structure and relationships, compared to simply stating they are bodies orbiting the sun?
