Yeah, from the kind of Buddha who only grows in width, who conflates
having briliant head with having brilliantine on head and who makes
many mentions about his hi-life style, like "I love dining out" until
someone curious finds what that means - the guy goes outside a house
and eats from his own garbage. Then there comes a suspicion he actually
enjoys being part of great suffering and wants to pull every living
creature into this and be their king in a hell of his own invention.

A nature of lousy anti-Buddha, not the one I would like to follow or
even beat with a ten foot stick. Just run away.

(About the foot note, not the black hole.)


Unix indeed has the Buddha nature. 

Microsoft has made available Windows Subsystem for Linux (WSL).
- https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux

Now even Windows 10 can have the Buddha nature.

I believe that figure was from an old measurement, M87's Black Hole is now
thought to be  6.6*10^9 solar masses +- 0.4.

I don't know why I got millions reduced to thousands and billions to 
millions. I looked up the mass of M87 BH and I find 2.5 billion solar 
masses.

Sgr*A is  4.5 million solar masses, the Black Hole in M87 is 6.5 billion
solar masses. From the earth they would have almost the same size even
though one is much closer than the other. And any radio telescope can
observe M87 but only those in the southern hemisphere can see Sgr*A. There
is probably less obscuring dust between us and M87 too because we don't
have to look through the long axis of our galaxy to see it.

 The image is constructed from a radio telescopic interferometer. The 
colors are in effect codes for the intensity of radiation coming off gas in 
an accretion disk around the black hole. The gas around the black hole was 
predicted to be more of an accretion donut, or proper spelling dough 
naught, and at first glance that is maybe what this is. We will have to see 
what the Sgr*A image looks like of the Milky Way BH that is smaller, 104 
thousand solar masses vs 2.5 million solar masses for M87*, but is closer 
only 27K light years, vs 55 million lyrs. 

To be honest I think the LIGO gravitational wave detection was more 
fundamental and really ground breaking. This is though interesting and it 
illustrates amazing resolution. The M87 BH is around two to three the 
radius of the solar system. So this technique will be used to look at a 
wide range of astrophysical systems.
