Black Hole Found in Globular Cluster!
If any pleasure approaches that of scientific discovery, it can be found in the cockpit. Flying high above the Earth puts many problems in perspective. Cities at night are ablaze with a million lights. From experience we know that the pools of light are just a hint of the mass below. Between those lights are roads, buildings, and people going about their business. The majority of mass lies hidden in the darkness.
When they have nothing better to do, scientists speculate about multiple universes. Another Universe does exist, occupying the same Space/Time but hidden from our eyes. Theory predicts, and observations confirm, that the mass we can see is just 4.507034% of the total. To be aware of the other 95.49% is to be a seeing woman among the blind.
Globular cluster Messier 80 contains hundreds of thousands of stars orbiting our Milky Way. Astronomer Harold Shapley used observations of these objects to locate the galaxy’s centre. A globular cluster contains some of the oldest stars in our galaxy. Astronomers did not know how the globular clusters formed so early, or what holds them together. One way to form them would be from a medium-sized Black Hole captured by the Milky Way. Since this Black Hole formed primordially, it would have been a magnet for early star formation.
The prediction above was written some weeks ago, for a book yet to be published. With a nod to Kea, there is some wonderful news. BBC reports discovery of a medium-sized Black Hole inside a globular cluster! Obervations were made by ESA's XMM-Newton satellite with follow-up observations by the Chandra X-ray Observatory.
Astronomer Tom Maccarone said, "We were preparing for a long, systematic search of thousands of globular clusters with the hope of finding just one black hole. But bingo, we found one as soon as we started the search."
The Beeb continues: "Some models have suggested that large black holes - several hundred times the mass of our Sun - could develop in the densest inner regions of clusters. Other simulations, however, predict that such gravitational interplay would probably eject most or all of the black holes that form in such an environment."
One lesson is: Don't trust computer simulations! They are not nature. My computer says Lara Croft can fight with those boobs. It is now likely that every globular cluster contains a Black Hole.
The Black Hole is predicted to have been there before the globular cluster. It provided an anchor for the cluster to form. It is wonderful, wonderful to make a prediction that turns out to be true.
