Both are atomic, both are gravitative, both possess elasticity, and both possess density.
With an atomic and gravitative aether it is shown in Chapter IV.
Now let us see how such a conception compares with our hypothesis of a gravitative Aether.
The prolate or lemon-like shape is caused by the gravitative pull of the earth, balanced by the centrifugal whirl.
We are now assured that there is something else in the universe which has no gravitative property at all, namely, the ether.
Let us consider the question whether Aether is, or is not gravitative, from another aspect.
As we have already seen (Art. 37), if there is one truth that they teach us regarding matter, it is that it is gravitative.
I refer to the effect of an atomic and gravitative Aether upon Newton's corpuscular theory of light.
The motion of the earth in its orbit implies the whole of this vast field of gravitative relatedness.
Such a result is exactly what should happen provided that Aether has an electric basis, and that Aether is gravitative.
