<h2><SPAN name="Authors_Note" id="Authors_Note"></SPAN><span class="smcap">Author's Note:</span></h2>
<p>To all profound thinkers in the realms of Science
who may chance to read <span class="smcap">Skylark Three</span>, greetings:</p>
<p>I have taken certain liberties with several more or
less commonly accepted theories, but I assure you that those
theories have not been violated altogether in ignorance.
Some of them I myself believe sound, others I consider
unsound, still others are out of my line, so that I am not
well enough informed upon their basic mathematical foundations
to have come to any definite conclusion, one way or
the other. Whether or not I consider any theory sound, I
did not hesitate to disregard it, if its literal application would
have interfered with the logical development of the story.
In "The Skylark of Space" Mrs. Garby and I decided, after
some discussion, to allow two mathematical impossibilities
to stand. One of these immediately became the target of
critics from Maine to California and, while no astronomer
has as yet called attention to the
other, I would not be surprised to
hear about it, even at this late date.</p>
<p>While I do not wish it understood
that I regard any of the major
features of this story as likely to
become facts in the near future—indeed,
it has been my aim to portray
the highly improbable—it is my
belief that there is no mathematical
or scientific impossibility to be
found in "Skylark Three."</p>
<p>In fact, even though I have repeatedly
violated theories in which
I myself believe, I have in
every case taken great pains to
make certain that the most rigid
mathematical analysis of which I
am capable has failed to show that
I have violated any known and
proven scientific fact. By "fact" I
do not mean the kind of reasoning,
based upon assumptions later shown
to be fallacious, by which it was
"proved" that the transatlantic
cable and the airplane were scientifically
impossible. I refer to definitely
known phenomena which no
possible future development can change—I refer to mathematical
proofs whose fundamental equations and operations
involve no assumptions and contain no second-degree uncertainties.</p>
<p>Please bear in mind that we KNOW very little. It has
been widely believed that the velocity of light is the limiting
velocity, and many of our leading authorities hold this view—but
it cannot be proved, and is by no means universally
held. In this connection, it would appear that J. J. Thompson,
in "Beyond the Electron" shows, to his own satisfaction
at least, that velocities vastly greater than that of light are
not only possible, but necessary to any comprehensive investigation
into the nature of the electron.</p>
<p>We do not know the nature of light. Neither the undulatory
theory nor the quantum theory are adequate to explain
all observed phenomena, and they seem to be mutually exclusive,
since it would seem clear by definition that no one
thing can be at the same time continuous and discontinuous.
We know nothing of the ether—we do not even know
whether or not it exists, save as a concept of our own extremely
limited intelligence. We are in total ignorance of
the ultimate structure of matter, and of the arrangement
and significance of those larger aggregations of matter, the
galaxies. We do not know nor understand, nor can we
define, even such fundamental necessities as time and space.</p>
<p>Why prate of "the impossible"?</p>
