If dark matter does exist it could explain some of the questions about our universe. Like what was here in the beginning.

My personqal opinion is that neither dark matter nor dark energy exists. They are simply something made up to preserve the current theory of gravity. As the article noted, "luminous ether" was another such made up thing. Eventually Einstein came along and provided a new theory that explained the problem with the old theory. Eventually a new genius will come along and explain the current observations.

My personqal opinion is that neither dark matter nor dark energy exists. They are simply something made up to preserve the current theory of gravity.

In a presentation of dark matter and dark energy, that I saw on t.v.Tuesday, it was quite the opposite of gravity. It was believed to be the force that pushed against objects of mass, actually contributing to the expansion of the universe.
It was believed that there was no central point of expansion. No matter where you stood in the universe all objects seemed to be expanding away from you in all directions.
An example of spheres on a rubber band was used. When you pulled on the ends of the band the objects, attached to it, moved with equal distance between them. To an observer on any one sphere would observe the spheres on each side moving away equally.

My personal problem with the expansion of the universe, from one big bang in a central location, is that the objects on the outer edge would loose its momentum due to the gravity of the large mass behind it, causing a sort of pile-up from the edge back-wards. Without a continuous push, how could the expansion continue for these billions of years?

I believe that our problem with explaining such things is that we are on the inside of the universe looking out. If we could observe from the outside we might understand better.

I quite agree, however I don't think that just because it was theorized to make an opposite for gravity that it's not true.

We have a bi-cameral science, for lack of a better word. We always want two things. Yes and No, Day and Light, Oceans and Land.

Consider now another one of my personal theories.
What if dark energy is some sort of static charge that is a little different from the discrete packets of positive charge carried by protons and the discrete packets of negative charge carried by electrons.

Now, consider the beginning of our universe in darkness.
Remember the process that makes xerox work: a piece of glass is charged with static electricty then, when the glass is exposed to a light, the static charge is released from the glass by the light.

Back to the universe in darkness, let there be light.
A single light source could have sparked the release of energy.
