The dying sun “Part 2”

We believe, however, that some two thousand million years ago this rare event took place, and that star, wandering blindly through space, happened to come near the sun. Just as the sun and moon raise tides on the earth, so this second star must have raised tides on the surface of the sun. But they would be very different from the little tides which the small mass immense tidal wave must have travelled over the surface of the sun at last forming a mountain so high that we can hardly imagine it.
As the cause of the disturbance came nearer and nearer, the mountain would rise higher and higher. And before the second star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw of small parts of itself into space. These small pieces have been round the sun ever since. They are the planets, great and small, of which our earth is one.
The sun and the other stars we see in the sky are all extremely hot-- far too hot for life a exist on them. So also no doubt were the pieces of the sun when they were first thrown off. Gradually they became cooler, until now they have very little heat of their own left, their warmth coming almost entirely from the radiation which the sun pours down on them. In course of time one of these cooling pieces gave birth to life. We do not know how, when or why this happened.
