A new study combining data from the European Southern Observatory's Very Large Telescope and the European Space Agency's XMM-Newton X-ray space observatory has turned up a surprise. Most of the huge black holes in the centres of galaxies in the past 11 billion years were not turned on by mergers between galaxies, as had been previously thought.


Fascinating stuff, Makes you think what created them.

“One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don't throw it away.”

From the same article:

“hey indicate that black holes are usually fed by processes within the galaxy itself, such as disc instabilities and starbursts, as opposed to galaxy collisions.

11 billion years ago, stars were MASSIVE. An average star would have the mass of 200 solar masses. Even though 200 solar masses is nowhere near the several hundered solar masses quasars have, but dark energy wasn't as strong then. That ment that stars were closer together and the force of gravity probably made these monsters as the middke ir galaxies (or quasars) has the highest stellar density.

What is true, just, and beautiful is not determined by popular vote. The masses everywhere are ignorant, short-sighted, motivated by envy, and easy to fool. Democratic politicians must appeal to these masses in order to be elected. Whoever is the best demagogue will win. Almost by necessity, then, democracy will lead to the perversion of truth, justice and beauty. -Hans Hermann Hoppe

A supermassive black hole is obviously formed when neutron stars collide
