New scientific theories are cropping up all the time. And that is just what they are - theories. So the Higgs boson particle has been seen. What a lot of tripe this is. It has only been shown to exist mathematically. The particle itself is still not proven to exist. Large galaxies eat up smaller ones. It would have been thought that this had been believed for some time. Apparently it hasn't been generally accepted. New findings show that the Milky way will be absorbed into larger galaxies billions of years from now. The Milky Way did expand by taking in smaller galaxies. Now it has peaked and this slowing down will allow Andromeda to absorb our home galaxy. When the Magellanic Clouds become part of the Milky Way that will be about it. As galaxies become larger they produce less stars. The reason for this is not known. There are a lot of conflicting theories about this.

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
