Supermassive Black hole found at center of our galaxy

(CNN) — German astronomers say they have discovered conclusive proof of a supermassive black hole at the heart of the galaxy.

The center of the galaxy is a unique laboratory for astronomical study.

The center of the galaxy is a "unique laboratory" for astronomical study.

The 16-year study involved tracking the movement of 28 stars at the center of the Milky Way using telescopes at the European Southern Observatory in Chile.

Using the data collected, astronomers were able to calculate important properties about the black hole — called Sagittarius A* — such as its size and mass.

Professor Reinhard Genzel, who led the study at the Bavaria-based Max-Planck Institute for Extraterrestrial Physics, said the data collected proved the existence of the black hole “beyond any reasonable doubt.”

“Undoubtedly the most spectacular aspect of our long term study is that it has delivered what is now considered to be the best empirical evidence that super-massive black holes do really exist,” said Genzel. The black hole had a central mass concentration of four million solar masses, he added.

  1. Many views on the Origin of Universe are available. Most popular view is that universe was born with a big-bang from a highgly dense energy point. But I have some different view on it. I think the universe was not born from a concentrated point or ball like structure but it has been evolved from an infinite vast expanse of field of gravity. Philosophically or religously we may call it field of consciousness or spirituality.

    A great flow of current of gravitation force descended down from this source and has created many regions of pure gravitation force below it. This was the creation for quite some time in the first phase of the creational process. In the second phase when when the current of gravitation force further descended down then electromagnetic forces and matter (weak and strong nuclear forces)manifested and the entire universe of the second phase was completed with the admixture of all the forces viz., gravitatin force, electromagnetic forces, and matter (weak and strong nuclear forces. The completion of the whole cosmos in two phases was also hinted in one of the speeches of Prof. J.V.Narlikar some years back. When the process of creation of universe reverts back in Brahmand (universe created during second phase of creational process)the matter merges into electromagnetic force and then finally electromagnetic forces merge into gravitation force and nothing remains except field of gravity in a highly dense body (Black Hole. The process of reversal does not take place in the universe created during first phase of creation. The cycle of universe completes like this.
