How to weigh a supermassive blackhole!

[nick c]

In an amazing pirouette of circular logic, astronomers have found a way to weigh a supermassive blackhole!

Since the existence of a supermassive blackhole at the center of spiral galaxies is considered established, the tightness of the spiral arms is an indicator of how massive is the black hole at the center.

Galaxies holding heftier black holes at their centers also have more tightly wound spiral arms, an astronomer announced today.


The finding gives astronomers a way to weigh so-called supermassive black holes, which can have masses of millions to billions that of the sun, and are thought to reside at the centers of galaxies.

Well, at least they said "thought to reside at the center of galaxies."
But no one thinks to question the gravity only model and its' inability to explain the observed structure of spiral galaxies, this necessitates the insertion of a 'fudge factor'....the Black Hole, condensing mass into an infinitesmally small point, essentially dividing by zero.

The stellar remnant eventually collapses to a point of zero volume and infinite density (called a singularity), and nothing, not even light, can escape its clutches.

So then, after all this, it is still not enough.

Seigar and his colleagues are not sure why spiral arms wrap more tightly around heftier supermassive black holes and more loosely for the lightweight supermassive black holes.

They have explained nothing. What they need is more MAGIC!!!
So, just as when Ricky comes home to Lucy, she's got some 'splainen to do.' But, she resourcefully comes up with an explanation:

But they think dark matter, mysterious matter thought to have played a critical role in the formation of the first galaxies after the Big Bang, could be the driving force.

Now it all makes sense!
