“Today, nothing is more important to the future and credibility of science than liberation from the gravity-driven universe of prior theory. A mistaken supposition has not only prevented intelligent and sincere investigators from seeing what would otherwise be obvious, it has bred indifference to possibilities that could have inspired the sciences for decades.”
The human body is subjected as well as the earth, and planets, and stars, to a double law; it attracts and repels, for it is saturated through with double magnetism, the influx of the astral light. Everything is double in nature; magnetism is positive and negative, active and passive, male and female. Night rests humanity from the day's activity, and restores the equilibrium of human as well as of cosmic nature.
We are at first irresistibly or unwittingly drawn within its dark circle by that peculiar influence, that powerful current of magnetism which emanates from ideas as well as from physical bodies.
These views corroborate what we have expressed about the various names given to the same thing. The disputants are battling about mere words. Call the phenomena force, energy, electricity or magnetism, will, or spirit-power, it will ever be the partial manifestation of the soul, whether disembodied or imprisoned for a while in its body — of a portion of that intelligent, omnipotent, and individual WILL, pervading all nature, and known, through the insufficiency of human language to express correctly psychological images, as — GOD.
Dark Energy appears to be, based on the brightness of the most distant type-Ia supernovae, a mysterious force that is accelerating the expansion of the universe. These recent discoveries have provided good evidence that there is such an outward force on the universe (variously called the cosmological constant, "quintessence," or "dark energy").
Data about the rotation of galaxies shows us that the outer parts rotate as fast as the inner parts. This only makes sense if there is a spherical distribution of matter in each galaxy, which is not what we see. Therefore we infer that there is a certain amount of Dark Matter in each galaxy. This could be some exotic particles, or just lots of stars too small to have ignited.
Aside from this, there is also the Dark Matter that we think is there, based on theoretical arguments. This is something we can measure by looking at the cosmic microwave background and distant supernovae. These are the measurements (recently made) that imply the existence of both Dark Matter and Dark Energy.

Simply put, even after all of our great advances in science namely physics, we still have absolutely no clue on why there is gravity and what gravity is made of.
Unlike subatomic particles that make up matter and energy as we know them, gravitons are elementary particles that compose the fabric of space and time.

Is gravity classed as an energy?
Could gravitation be related to dark energy
in that one is there to keep an equilibrium with the other?
As the universe expands I guess dark energy increases?
So why doesn't gravitation increase too?
It does but we don't directly feel the effects because the extra gravitation is mainly absorbed by blackholes forming...erm and stuff.
Have all my questions already got simple answers?
Perhaps this should be a work of the skunk variety?

What makes you think that, I mean it sounds plausible, I am just wondering what research you have seen or done.
The effects and the analysis so far lead to the following possible interpretations: 1. The effects are real: A frame-dragging-like signal was detected from spinning rings at cryogenic temperatures. The effect occurs below a critical temperature which does not coincide with the superconducting temperature of the rings. The strength of the effect depends on the material of the ring. The coupling factor of the observed effect with respect to the applied angular velocity is in the range of 3-5×10-8. We observed a parity violation, such that the effect is dominant in the clockwise rotation (when looking from above) in our laboratory setup. No classical or systematic explanation has been found so far for the observed effects. The field expansion is not clear at the moment and needs further investigation.
Galaxies and the universe need dark matter or dark energy for their explanation. First public peek at Gravity Probe B results (GP-B) shows that both geodetic and frame-dragging effects are larger than GR predictions by the gap of about 25 mili-arc-second/year, i.e., mas/yr. Do we need dark matter even at our home? I suggest that there is no dark matter at all. But we need more gravity. I propose the principle of universal gravitation due to rotation. Any part of a rotational mass generates a force which is proportional to the product of the mass point and its squared relative velocity (relative to light speed c). Similar to Newton law, the force is proportional to the other mass on which the force is exerted and inversely proportional to the square of the distance between the two mass points. The suggestion is justifiable because both mass and rotation (spin) are invariant properties of nature. Because rotational gravity is anisotropic and is larger in equator direction, we had a simple explanation to why solar system is planar and all rotations are approximately in the same plane. Rotational gravity also suggests the possibility of anti-gravity. It is shown that the above GP-B gap can be covered by the new gravity. My prediction on geodetic effect is larger than GR by about $35\times H$ mas/yr while the frame dragging effect is larger by 19.5 mas/yr. Here $H$ is another constant associated with rotational gravity which plays the role of Newton gravitational constant $G$. I also present the quantization of covariant gravity and solar application.

Unlikely, since - as you know - they act in opposition to one another.
