The Sky is an Ocean. The Earth is an Island.And the Solar System

The Greek etymology of the word "cosmos" returns to the concept of order, and space is often assimilated to the void. But is this ocean as uniform and immutable as it seems to be ? Astronomical numbers are necessary to describe it, which does not mean that they exceed the human experience, but that they occupy all the possible scales, from the very large to the very small, including familiar ones : the galaxies gather billions of stars, in a space measuring thousands of light-years, but to understand some phenomena, it is necessary to consider sub-atomic particles of a lifespan not exceeding infinitesimal split seconds. In the same time, explosions of supernovae may occur in only a few days, and elsewhere, on other planets, storms, tides, and seasons, proceed like in Earth.
