Now, in order for any of these planets to fulfil Newton's First Law of
Motion, the sun, which occupies the centre of the solar system, must be
assumed to have no rotatory or orbital motion of its own; because, so
long as it has a rotatory motion on its axis, or an orbital motion of
its own through space, so long will even the first part of Newton's
First Law of Motion be inapplicable to the solar system.

But if the sun can be assumed to possess at some point in its history no
orbital motion, or rotatory motion on its axis, then the physical
interpretation of the first law of motion can be physically conceived,
and a planet at rest will remain at rest relatively to its central body,
the sun, for ever.

Let us take the sun and Mercury as an example of the effect of the two
motions operating in the aetherial medium. We will consider first the
effect of the centrifugal motion. The sun, with its huge form, occupies
the centre of the solar system, while Mercury has its mean distance
about 36,000,000 miles away.

The solar fires are intensely burning, and every atom and every particle
composing them are excited thereby into the most intense activity, and
by their energy of motion create myriads upon myriads of waves in the
surrounding Aether, which flow away on every side with the velocity of
light.

With such velocity are they generated, that they speed across the
distance of 36,000,000 miles which exist between Mercury and the sun in
the short time of about three minutes, and if it were not for the
aetherial and aerial atmosphere of the planet, would fall upon the
surface of Mercury with an intensity of heat that would scorch up all
vegetable life, if any existed thereon.

Now let us for a moment ignore the existence of the centripetal force,
and then in that light view the influence of the electro-magnetic Aether
waves upon Mercury. We have seen that when aetherial light waves come
into contact with any body, they exert a pres
