We can only See 5% of the universe

The Missing Universe
The mystery of dark matter may at last have been solved
By Michael D Lemonick

 The universe is a lot of things, but easy to understand isn't one of them. Take the fact that more than 80% of its mass is missing. Galaxies spin so fast, they would fly apart if the gravity of some unseen mass weren't keeping them intact, surrounding them like a glass paperweight encasing a butterfly. Cosmologists have been trying to identify this so-called dark matter since the 1930s, and now they may have succeeded thanks to new data from a spectrometer aboard the International Space Station.

Dark matter particles are hard to spot since they can pass through ordinary matter as if it weren't there--billions could be streaming through your body as you read these words--but we can detect their by-products. When two of the particles collide, they give off an ordinary electron and its anti-matter counterpart, the much rarer postitron. In the two years the spectrometer has been in operations, it's detected 400,000 positrons--a number consistent with what models suggest the frequency of dark -matter collisions should be.

The particles could be from some other source: the spectrometer has years of operational life left in which to nail down the answer. Even if it does, the riddles aren't over. Dark matter and ordinary matter make up all the mass that exists, but that represents only 32% of the universe. The rest? Dark energy, which pulls things apart as dark matter pulls them together and helps explain why the universe is expanding. That 68% of all there is remains  deep mystery.

Here is the breakdown by percentage
5 percent-ordinary physical matter that we can see visibly
27% dark matter
68% dark energy

end quote from page 15 of the April 22nd 2013 Time magazine.

What I find interesting is that dark matter and dark energy are likely everywhere in the universe including right here with you and me right now. However, it likely doesn't exist in a time space universe that we live in. So, since it likely might exist in another even parallel time and space or no time or no space it is difficult to come to grips with it for scientists. The visible 5%  of the universe that we live in follows the rules of a Time Space continuum and as far as I now know, neither dark matter nor dark energy exists in a time space continuum in which we exist in here on earth.

Also, the name "Dark Matter" conjures an idea of something sinister or unknown. I would say the time space universe we live in is the actual anomaly AT 5% and the 95% of normal universe likely should be called "The INFINITE SEA OF LIFE".
