Dark matter holds the universe together right?  Well, the theory of dark matter may be widely believed, but there isn't much of it in our part of the universe.  The research team puts forward its findings.  Believers question the accuracy of what they have found. This isn't a question of how much is out there.  The team found no dark matter at all.  The dark matter theory holds that dark matter should be plentiful, everywhere.  As much as 85 per cent of everything should be dark matter.  The sun should be pulled around with dark matter.  Unfortunately, scientists cannot find it. Dark matter theory is based on the premise that stars trapped in a gravitational well light years away travel at a fixed speed.  This, with the shape of the well allows a calculation to be made.  Star counts give the amount of ordinary matter.  subtracting this from the mass determined from the calculation gives the amount of dark matter. The team found that the dark matter theory was quest

We now know that dark matter exists. NASA's Hubble Space Telescope has also identified blue straggler stars in the Milky Way. These stars don't show their age. Their color hides their true age. This is the first time they have been found in the core of the Milky Way. Not much is known about blue stragglers. Accepted theory is that they develop from binary pairs. The larger of the pair strips material from the smaller one. Hydrogen is activated which causes the larger star to undergo nuclear fission thus making the star blue. Blue stragglers are rare in the Milky Way because the central bulge of the system stopped making new stars billions of years ago. Aging stars and cool red dwarfs exist in the Milky Way now. Giant blue stars were thought to have exploded into supernovae in the distant past. The presence of blue stragglers throws a spanner into the works of current models of star formation. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspo

Dark energy is no longer theory it is fact. Evidence from 200,000 galaxies confirms the hypothesis that dark energy is pulling the universe apart. It is a constant in that it pushes uniformally causing steady expansion of the universe. Einstein was correct after all. He said there was a force pushing out stopping the universe from collapsing. This was known as "Einstein's biggest blunder'. He had to enter something into an equation which stopped the universe from collapsing. Though he didn't use the term "dark energy", this was the force he was talking about. He was wrong about the universe being static but he quickly revised his ideas when Edwin Hubble found that the universe was expanding. Gravity is no longer accepted as the force driving the universe apart. Gravity cannot push and pull at the same time. Calculations show that dark energy makes up 74 per cent of the universe. Dark energy is not he same as dark matter. There is 22 per cent of dark
