On the one hand, the extraordinary gravity of the earth is pulling these reservoirs of water towards it, and on the other hand, there is about a five-mile thick cover of air over the seas, which maintains pressure over the seas. For these two reasons the water remains continuously in the seas, otherwise all the water would have flown up into space. The same is true of ships floating on the seas. Here also the law of nature laid down by God is in force.
According to this law whenever anything is put into water, the upward pressure by the fluid on the body, partly or wholly immersed therein, is equal to the weight of the fluid displaced. This, in terms of the discipline of hydrostatics, is known as buoyancy.
Another matter of subjection relates to outer sphere. The vast space all around the earth is filled with huge hot stars, hence the expression, starry universe. All these stars are situated at a fixed distance from the earth. If this fixed distance were not maintained, the entire earth would be burnt to ashes.
When we look at the open sky at night from the earth, we see many stars of an apparently diminutive size. These stars are actually huge, but they appear small because of their remoteness. When we observe with the naked eye, about 10,000 stars are visible. These stars are part of our galaxy, the Milky Way.
In the vastness of space, there are innumerable very big stars which are always in motion. There are more than one hundred billion galaxies and in every galaxy there are about one hundred billion stars.
Man could not see this vast world of stars by the naked eye, so God placed such material resources in the world by discovering and developing which man was enabled to build powerful telescopes. That is how in modern times man has made use of these resources to develop space telescopes, and is now able to see countless stars in the galaxies.
The subjection of seas and animals meant that man was
