Why is 96% 0f the Universe "Dark"? Part VI

-1599 - Why is 96% of the Universe “ Dark”? What else could explain how these conclusions could not be true.

----------------------- # 1599 - Why is 96% of the Universe “ Dark“? ( Part VI of VI )

-

- The equations that explain the Big Bang theory for the Universe come out of the Cosmic Microwave Background radiation image that can be made to expand over 13.7 billion years to the web of galaxies and voids we observe today. This expansion assumes that the geometry of the Universe is “ flat”. It concludes that the ratios of the repulsive energy to the attractive energy is 73% to 27%.

-

----------------------- 73% anti-gravity repulsion

----------------------- 23% gravity attraction by matter we can not see

----------------------- 4% gravity attraction by matter that we can see.

----------------------- 100% matter- energy total in the Universe.

-

- How can we show that the geometry of the Universe is “flat”.

-

- When we measure the Cosmic Microwave Background radiation with the highest resolution to detect 1 part in 100,000 variation, we can see the variations in hotter and colder patterns, denser and rarified patterns.

-

- These small variations expanded over 13.7 billion years at 47,000 miles per hour per million lightyears expansion rates create the galaxies and voids we observe today.

-

- Plotting this expansion over time. Plotting a triangle of distances connecting 3 points in these patterns. Creating 3 angles of a triangle always adds up to 180 degrees. The triangle must exist on a flat plane. If the triangle was on a spherical geometry the sum of the angles would more than 180 degrees. If the geometry of the Universe’s expansion were more like a hyperbola, or a saddle shape, the some of the angles would be less than 180 degrees. As far as we can measure the geometry of the expanding Universe its geometry is perfectly flat.

-

- The geometry might be different in the future. The Universe’s expansion was dominated by the attractive force of gravity for the first 5 billion years. It has been dominated by the anti-gravity repulsive force of Dark Energy over the last 5 billion years. Measured today the two forces about cancel out and we see the geometry as perfectly flat. It appears that Dark Energy is the dominating force in the future expansion of the Universe making the shape of the Universe a hyperbola. An accelerating expansion that will dilute all matter in the Universe until it is cold an empty.

-

- Are there other explanations that could change this conclusion?

-

- Do the laws of gravity change at different scales of the Universe? We can modify the equations for different laws of gravity at different scales. They even work with specific observations. But, these same equations do not work under other observations. So, we still think these same laws of physics apply every where in the Universe.

-

- Could there be ordinary matter out there that we are not counting because we can not see it? There could be dim stars, Brown Dwarf stars, asteroids, even planets that are invisible to us with today’s technology. Attempts have been made to detect unseen matter by using gravitational lensing. Could there be enough neutrinos to account for the missing mass? Adding all these speculations up together can not account for the 23% of Dark Matter that comes out of the calculations. Everything we can account for does not total to more than 4 ½% of the total in the Universe.

-

- Could the vacuum of space create a negative density that appears as an anti-gravity force? All attempts to make this theory work fail.

-

- Could there be a missing particle. A weakly interactive massive particle, a WIMP, that physics has not yet detected? There is a theoretical explanation called “Supersymmetry“ that adds massive particles to the Standard Model of Particles. This is still a good candidate for an explanation, but, these particles have yet to be discovered.

-

- An announcement will be made shortly, stay tuned. In the meantime 96% of the Universes remains “ Dark”. Are you convinced?
