Volume Three--The Business Outline of Astronomy

Оглавление

Table of Contents

The world or universe in which we do our business consists of an infinite number, perhaps a hundred billion, perhaps not, of blazing stars accompanied by comets, dark planets, asteroids, asterisks, meteors, meteorites and dust clouds whirling in vast circles in all directions and at all velocities. How many of these bodies are habitable and fit for business we do not know.

The light emitted from these stars comes from distances so vast that most of it is not here yet. But owing to the great distance involved the light from the stars is of no commercial value. One has only to stand and look up at the sky on a clear starlight night to realize that the stars are of no use.

Practically all our efficient light, heat and power comes from the sun. Small though the sun is, it gives out an intense heat. The business man may form some idea of its intensity by imagining the entire lighting system of any two great American cities grouped into a single bulb; it would be but little superior to the sun.

The earth revolves around the sun and at the same time revolves on its own axis, the period of its revolution and the rising and setting of the sun being regulated at Washington, D.C. Some years ago the United States government decided to make time uniform and adopted the system of standard time; an agitation is now on foot--in Tennessee--for the lengthening of the year.

The moon, situated quite close to the earth but of no value, revolves around the earth and can be distinctly seen on a clear night outside the city limits. During a temporary breakdown of the lighting plant in New York city a few years ago the moon was quite plainly seen moving past the tower of the Metropolitan Life building. It cleared the Flatiron building by a narrow margin. Those who saw it reported it as somewhat round but not well shaped, and emitting an inferior light which showed that it was probably out of order.

The planets, like the earth, move around the sun. Some of them are so far away as to be of no consequence and, like the stars, may be dismissed. But one or two are so close to the earth that they may turn out to be fit for business. The planet Mars is of special interest inasmuch as its surface shows traces of what are evidently canals which come together at junction points where there must be hotels. It has been frequently proposed to interest enough capital to signal to Mars, and it is ingeniously suggested that the signals be sent in six languages.
