Gravity,Dark Matter and Dark Energy

Reference to Dark Matter
            We have covered the common but mysterious force, gravity.There are two more mysterious forces related to gravity.Scientist believe they exist, even though they can't be seen or detected, because of their effect on galaxies and the universe as a whole.
            Dark Matter: Recent observations by scientists has led them to believe there must be way more mass or matter in the galaxies because the known mass that we can see and detect,does not account for the rotational speed of the galaxies or their velocity in clusters.
             In other words, all the matter that can be seen or detected is not enough to keep the galaxies from flying apart.Something else is holding the galaxies together.Scientists are baffled by this phenomena. So they have concluded that there must be something else, that can't be seen and gives off no radiation.. They have concluded that this mysterious dark matter exists because of the gravitational pull it exerts on normal stars and galaxies.They have given this invisible and undetectable force a name: Dark Matter.
            Dark Energy:When studying the universe over the last fifty tears, scientist have concluded that the universe is not only still expanding, but the expansion is accelerating.Nothing that is known accounts for this, as there is nothing but empty space between the galaxies.What is causing this repulsive force that is forcing the outer galaxies of the universe to rush away from each other.Scientist have no idea but have given this force a name: Dark Energy.
            Scientist have separated these forces that react with matter,gravity,dark matter and dark energy. Why are they separated?All three interact with matter but in different ways.What if  they are the same force?What if gravity can change it's strength according to the task it wants to accomplish.  Think of an engine in a car.It powers the wheels, the air conditioner and it generatesw it's own power. Three seperate tasks performed by a single entity.I know, this goes against Einstein's theory of relativity. But maybe gravity is more complex than first thought.
           So, what can we conclude from this?Strange forces ,that cannot be seen or detected with our most advanced  scientific instruments, determines the shape,size and the very existence of the universe we inhabit.
            More evidence that these forces are controlled by a higher intelligence. If it was just random, why does it work perfectly?
             What if dark matter interacted with the earth? We would be crushed. What if dark energy interacted with the earth? We would be torn apart.
            This is further evidence that the universe is not ruled by chaos but by intelligent design. How can it be , that these undetectable , mysterious forces which  work with such precision exist for our benefit by a lucky chance?
             Think about it, these forces have a purpose.
