Dark matter, in a nutshell, is a theoretical force envisioned by scientists that would explain the behavior of galaxies that seem to be spinning fast enough for some of their stars to fly out of their orbits but do not. For galaxies to remain intact they would have to have a greater gravitational pull than their visible mass suggests. Scientists therefore theorized, as far back as the 1930s, that there must be some invisible matter — dark matter — that’s holding galaxies together.
The problem is that as hard as we try to detect dark matter we cannot. And despite other theories to explain galaxies’ behavior, their rapid spin remains a mystery.
I’d like to propose a new theory that might shed some light on all this. A study done several years ago showed that the universe’s energy is decreasing. What if gravity, too, has been getting weaker? Not necessarily in lockstep or conjunction with the universe’s energy, or, perhaps there is a connection. Regardless, a diminishing gravity scenario — where gravity has been steadily declining since the beginning of time — would explain what appears to be dark matter.
When we look into the sky we see objects as they were many years ago. The additional gravity needed to hold a galaxy together actually was there at that time in the past. So when we calculate its gravitation pull based on today’s gravitational strength we come up short and assume there must be some kind of dark, invisible matter.
What’s more, a diminishing gravity theory also explains another puzzle that presents itself with the dark matter theory. Different celestial objects seem to have a vastly disproportionate amount of dark matter. Pretty difficult to explain.
With the diminishing gravity theory, however, even this problem disappears. Different celestial objects have different gravitational pulls because they formed at different times in the past and, therefore, actually had different gravitational strengths.
Furthermore, there’s an additional factor that would give heavenly objects greater gravitational pull than their sizes would suggest. Under a greater gravitational pull these objects would have coalesced with greater force and into more compact objects, giving them even greater gravitational pull than the same size objects compacted under weaker gravity. In this more compact form, these objects may very well exert greater gravity even today than other objects of the same size. This diminishing gravity theory is explained in more detail in “The V-Bang: How the Universe Began.”
What this boils down to is that older celestial objects will generally have greater gravity and therefore appear to have more dark matter. The relationship between distance from earth and age, however, is not as straightforward as current theory holds. This is also explained in detail in “The V-Bang.”
