The Science of Existence (14-5) Quasars

 Quasars

Quasars are immensely bright. From the central point in a galaxy, they emit as much energy as thousands of giant galaxies from a region as tiny as the solar system. ~ American astrophysicist Robert Antonucci

Quasars are the shiny companions to black holes. Powered by regurgitation from supermassive black holes, quasars appear as stunningly bright, distant stars. More than 200,000 quasars have been spotted. Quasars are powered by both the spin toward the black hole and the rotation of the black hole itself.

A quasar’s brightness corresponds to how much matter a black hole is consuming. When black hole intake slackens, the light goes out and black hole output is downgraded in human esteem. A typical quasar only lasts a few hundred million years.

Quasars are not always solely outflow. 1 out of 10,000 quasars feed the black hole from which they are formed. How that happens is not understood.

Quasars appear linked in a cosmic web of filaments and clumps in the vast voids where galaxies are scarce. The dynamics of large quasar group formation remain a mystery.

Some of the quasars’ rotation axes are aligned with each other, despite the fact that these quasars are separated by billions of light-years. ~ Belgian cosmologist Damien Hutsemékers

While the cause of disparate quasar alignment is uncertain, it is a clear indication of synchronism on a vast cosmic scale.

The alignments hint that there is a missing ingredient in our current models of the cosmos. ~ Belgian astrophysicist Dominique Sluse
