The tyre is the universe. The pebbles are objects of mass. The mass protruding the boundaries of the tires causing interaction is gravity, the stretching between objects as they push out in other directions is dark energy. The angle of force in any direction putting pressure on the surface is what causes difficulty with acceleration at high velocity. I though it was a good analogue. But you have to picture the universe as a hypersphere rotating in all directions.
Time is only one dimension and centrifugal force has nothing to do with gravity. Have you taken any physics classes?

The higher densities have mord Centrafugal effect, keep in mind I wrote an analogue, not a real picture. Asko keep in mind that you have to consider a minimum of four known diminsions, with time having all three that you interact with.

like air provides resistance to objects falling through the atmosphere?
something in space is providing resistance to the planets to keep them in the arms of the galaxy?

Picture a tyre rotating. This tyre is very elastic. There are pebbles in this tyre, scattered throughout the inner surface. Some of the pebbles are close, others far apart. As the tyre spins fast pebbles move further from the center (a point they can useally never go back to, almost always outward) and average distance between the pebbles increases with the circumference as is seen with dark energy. The pebbles which are relatively close will draw toward each other trying to escape the center point due to Centrafugal effect. This is gravity. Now as you go faster and faster agaist the curve you reach a point where you are pushing out of the universe due to your curved path trying to straighten, like sliding off a road into a guard rail on a corner. The faster you go, the less energy goes into moving forward due to elasticity and direction. Now instead of a tyre, this is a hypersphere with multidimensional rotation.
I don't have the connection for the physics knowledge I need now, so I can not write the equations.
Then came 1998 and the Hubble Space Telescope (HST) observations of very distant supernovae that showed that, a long time ago, the universe was actually expanding more slowly than it is today. So the expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating. No one expected this, no one knew how to explain it. But something was causing it.
