     summary: In the positive sense of the word, astronomy is more especially a science of _observation_, which is its _only_, but real and successful power. _ Astronomical science, at the present day insists upon the system of Copernicus, which, as is well known, is based upon the theory _of a fixed sun_, and remains convinced of the incontrovertible truth and importance of this system, even after it has become an incontestable fact, that the sun changes its position; endeavouring to explain away this discrepancy by the sophism, that the sun may be considered as _in a condition of rest_.

     summary: The individual dies, but the forces which gave life and strength to the race persist, and others will take his place, and the same forces will continue to operate with constant renewals, since we draw our light and heat and life from without; but in the death of suns and their attendant planets there is no analogous process, for such suns are constantly expending their enormous energies in the support of life external to themselves, and only the smallest part of this energy, even, can ever be utilized by themselves or by other suns or planets under any mode of interpretation now in vogue, the boundless realms of so-called inert and empty space receiving the same proportionate quota of light and heat as the almost microscopic points in the sky which constitute the suns and systems we see, and practically all, or nearly all, of this enormous energy is an absolute dead waste; so that whether receiving new supplies from a constant rain of adjacent meteor streams, or from the gradual contraction of the solar volume, the vast realms of space are the useless recipients of what can never return to the sun again, and, of course, in such case the inevitable end can be predicted; for contraction of volume, with a given mass, must have an effective limit, and meteoric aggregation must also find an effective limit, if the planets are not to be thrown out of place as they continue to revolve around the sun.
