Galactic rotation and Kepler

Kepler authored three laws of orbit. One of these stated that the closer a body
of mass orbits its partner, the faster it had to move to prevent being sucked
into the system’s center.
This works great in our solar system with the Sun at its center. The galaxy as
a whole, however, does not reflect the distance : speed ratio of the solar
system (Kepler’s laws). Instead all bodies seem to travel uniformly around the
center, keeping their alignment with closer and further bodies of mass (from the
galactic center).
From this modern scientists stipulated that there must be some sort of matter
which doesn’t interact with other (baryonic) mass save through gravity. This
is entirely unnecessary given the amount of normal/baryonic mass, which is the
kind of matter that we’re made of and used to.
A terrific analogy is a water eddie/whirpool. If you add some markers on top of
the water, you’ll see that the water on the outside circles the center at the
same speed as the water closer to center. This is because of the cohesion
between both segments of water. The water on the outside work on the inner
water. Gravity between outer solar systems work upon the solar systems on the
inside via gravity instead of cohesion. For this reason we dont need to invent
some mystical (non-baryonic / dark-) matter to explain this observable phenomena
