April 6. -- Last night had a fine view of Alpha Lyrae, whose disk,
through our captain's spy-glass, subtends an angle of half a degree,
looking very much as our sun does to the naked eye on a misty day.
Alpha Lyrae, although so very much larger than our sun, by the by,
resembles him closely as regards its spots, its atmosphere, and in
many other particulars. It is only within the last century, Pundit
tells me, that the binary relation existing between these two orbs
began even to be suspected. The evident motion of our system in the
heavens was (strange to say!) referred to an orbit about a prodigious
star in the centre of the galaxy. About this star, or at all events
about a centre of gravity common to all the globes of the Milky Way
and supposed to be near Alcyone in the Pleiades, every one of these
globes was declared to be revolving, our own performing the circuit
in a period of 117,000,000 of years! We, with our present lights, our
vast telescopic improvements, and so forth, of course find it
difficult to comprehend the ground of an idea such as this. Its first
propagator was one Mudler. He was led, we must presume, to this wild
hypothesis by mere analogy in the first instance; but, this being the
case, he should have at least adhered to analogy in its development.
A great central orb was, in fact, suggested; so far Mudler was
consistent. This central orb, however, dynamically, should have been
greater than all its surrounding orbs taken together. The question
might then have been asked -- "Why do we not see it?" -- we,
especially, who occupy the mid region of the cluster -- the very
locality near which, at least, must be situated this inconceivable
central sun. The astronomer, perhaps, at this point, took refuge in
the suggestion of non-luminosity; and here analogy was suddenly let
fall. But even admitting the central orb non-luminous, how did he
manage to explain its failure to be rendered visible by the
incalculable host of glorious suns glaring in all directions about
it? No doubt what he finally maintained was merely a centre of
gravity common to all the revolving orbs -- but here again analogy
must have been let fall. Our system revolves, it is true, about a
common centre of gravity, but it does this in connection with and in
consequence of a material sun whose mass more than counterbalances
the rest of the system. The mathematical circle is a curve composed
of an infinity of straight lines; but this idea of the circle -- this
idea of it which, in regard to all earthly geometry, we consider as
merely the mathematical, in contradistinction from the practical,
idea -- is, in sober fact, the practical conception which alone we
have any right to entertain in respect to those Titanic circles with
which we have to deal, at least in fancy, when we suppose our system,
with its fellows, revolving about a point in the centre of the
galaxy. Let the most vigorous of human imaginations but attempt to
take a single step toward the comprehension of a circuit so
unutterable! I would scarcely be paradoxical to say that a flash of
lightning itself, travelling forever upon the circumference of this
inconceivable circle, would still forever be travelling in a straight
line. That the path of our sun along such a circumference -- that the
direction of our system in such an orbit -- would, to any human
perception, deviate in the slightest degree from a straight line even
in a million of years, is a proposition not to be entertained; and
yet these ancient astronomers were absolutely cajoled, it appears,
into believing that a decisive curvature had become apparent during
the brief period of their astronomical history -- during the mere
point -- during the utter nothingness of two or three thousand years!
How incomprehensible, that considerations such as this did not at
once indicate to them the true state of affairs -- that of the binary
revolution of our sun and Alpha Lyrae around a common centre of
gravity!
April 7. -- Continued last night our astronomical amusements. Had a
fine view of the five Neptunian asteroids, and watched with much
interest the putting up of a huge impost on a couple of lintels in
the new temple at Daphnis in the moon. It was amusing to think that
creatures so diminutive as the lunarians, and bearing so little
resemblance to humanity, yet evinced a mechanical ingenuity so much
superior to our own. One finds it difficult, too, to conceive the
vast masses which these people handle so easily, to be as light as
our own reason tells us they actually are.
April 8. -- Eureka! Pundit is in his glory. A balloon from Kanadaw
spoke us to-day and threw on board several late papers; they contain
some exceedingly curious information relative to Kanawdian or rather
Amriccan antiquities. You know, I presume, that laborers have for
some months been employed in preparing the ground for a new fountain
at Paradise, the Emperor's principal pleasure garden. Paradise, it
appears, has been, literally speaking, an island time out of mind --
that is to say, its northern boundary was always (as far back as any
record extends) a rivulet, or rather a very narrow arm of the sea.
This arm was gradually widened until it attained its present breadth
-- a mile. The whole length of the island is nine miles; the breadth
varies materially. The entire area (so Pundit says) was, about eight
hundred years ago, densely packed with houses, some of them twenty
stories high; land (for some most unaccountable reason) being
considered as especially precious just in this vicinity. The
disastrous earthquake, however, of the year 2050, so totally uprooted
and overwhelmed the town (for it was almost too large to be called a
village) that the most indefatigable of our antiquarians have never
yet been able to obtain from the site any sufficient data (in the
shape of coins, medals or inscriptions) wherewith to build up even
the ghost of a theory concerning the manners, customs, &c., &c., &c.,
of the aboriginal inhabitants. Nearly all that we have hitherto known
of them is, that they were a portion of the Knickerbocker tribe of
savages infesting the continent at its first discovery by Recorder
Riker, a knight of the Golden Fleece. They were by no means
uncivilized, however, but cultivated various arts and even sciences
after a fashion of their own. It is related of them that they were
acute in many respects, but were oddly afflicted with monomania for
building what, in the ancient Amriccan, was denominated "churches" --
a kind of pagoda instituted for the worship of two idols that went by
the names of Wealth and Fashion. In the end, it is said, the island
became, nine tenths of it, church. The women, too, it appears, were
oddly deformed by a natural protuberance of the region just below the
small of the back -- although, most unaccountably, this deformity was
looked upon altogether in the light of a beauty. One or two pictures
of these singular women have in fact, been miraculously preserved.
They look very odd, very -- like something between a turkey-cock and
a dromedary.
