For the first time what was considered as the impossible has happened. It measures 40 billion km across – three million times the size of the Earth – and has been described by scientists as “a monster”. The black hole is 500 million trillion km away .A black hole named M87 has been photographed by a network of eight telescopes (the Event Horizon Telescope) across the world. Details have been published in Astrophysical Journal Letters.
The image shows an intensely bright “ring of fire”, as Prof Heino Falcke, of Radboud University in the Netherlands, (who proposed the experiment) describes it, surrounding a perfectly circular dark hole. The bright halo is caused by superheated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined – which is why it can be seen at such distance from Earth. The edge of the dark circle at the centre is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull, not even light can escape. (The other is Sagittarius A at the centre of the Milky Way.) To make this image, astronomers networked radio telescopes all over the world to magnify M87 to unprecedented resolution. No single telescope is powerful enough to capture the black hole, so a network of eight was set up to so do using a technique called interferometry.
Dr Katie Bouman and others developed a series of *algorithms that converted telescopic data into the historic photo shared by the world’s media.
(*In mathematics and computer science, an algorithm is a process or set of rules used to solve problems.)
This image forms a clear link now between supermassive black holes and bright galaxies,” said Sheperd Doeleman, a Harvard astrophysicist and director of the Event Horizon Telescope at a National Science Foundation press conference.
It confirms that large galaxies like Virgo A (and the Milky Way) are held together by supermassive black holes, Doeleman said.
Astronomers knew that black holes were surrounded by glowing matter. But this image still answers a key question about black holes, and about the structure of our universe. Einstein’s Theory of Relativity holds up even at the edge of a black hole, where some researchers suspected it would break down. The shape of the visible event horizon in the image is a circle, as predicted by relativity, so it confirms relativity still holds sway even in one of the most extreme environments in the universe.
Now we may ask ourselves why man grows old only to grow feeble or Why nationalism has people power behind it to make it strong and yet it must fail? The answer my friend is in the details and in as trivial as fundamental particles. There is an inversion principle built in. Our strength may lay in numbers. So we push nationalism as though nations can safeguard our best interest. Oh no, nations shall take away many of our freedom with the excuse it as a necessary evil ‘in the national interests’. (So you want your children safe from guns and give them a safe environment to grow in. But creepies are out there and they are ready to shoot for no reason because your color isn’t right. How safe are you because law makers have been already bought by NRA to sell more guns? Mind you an election is round the corner.)
General relativity governs very big things, like stars and gravity as Einstein had predicted. Whereas Quantum mechanics (which describes very small things) is incompatible with it. Here we have two workings that underpin our universe contrary to one another. For this reason stupid mullahs who preach hate and who send terrorists are merely eating their own flesh as white supremacists dig the very ground they stand on.

(Originally the post “1848 and Aftermath-Nationalism” appeared on March 17,2014. This is a retro on that post-b).
The year 1848 can be considered as the beginning of the modern Europe.
In an obscure German paper Karl Marx published
the Communist Manifesto. It was a challenge to the entrenched order
that was at best benevolent but despotic and exploitative.
It all began with violent
changes across the channel. In England was the Chartism and in Franc
Louis Philippe had been removed from the French throne in February 1848,
and revolutions
were soon to convulse other European capitals.
In early 1848
none of the greater states of Europe
functioned as democracies. Britain, where
about one-in-five adult males (in England) had voting rights,
and France, where voting rights
were allowed to very wealthy men, amounting to about
one-in-two-hundred
of all adult males, were the least undemocratic.
The other greater states
of Éurope – the “Austrian” Habsburg Empire, Prussia and Russia
operated as absolute monarchies
where such Assemblies of Notables, Congregations or Diets,
as were
authorised to convene were understood
to have administrative or consultative roles
rather than political or legislative powers.

The European Revolutions
of 1848 represent a widespead emergenc
of situations,
across much of Europe, where populist
human aspirations variously sought constitutional,
liberal, nationalist or socialistic changes
in society often at the cost of
traditionally influential dynastic
or religious authorities.
In February 1948, the British historian Lewis Namier (1888–1960) delivered
a lecture commemorating the centennial of the European Revolutions of 1848.
He presented facts about the historical developments and themes evident in 1848
and reached the conclusion that “1848 remains a seed-plot of history. It
crystallized ideas and projected the pattern of things to come; it determined
the course of the following century.”
Heartened by the French example a national revolt under the legendary Lajos Kossuth
demanding a parliamentary government for Hungary and constitutional government
for the rest of Habsburg Empire. As a result number of revolts sent Metternich out of
power and ripples as far as Italy. The movement for Hungarian Independence
lost by two reasons. Austria and Prussia despite their long running feud
closed their ranks to protect the divine rights of their rule,
Secondly the Czechs ,Romanians and Serbs within the empire resisted
thus proving the ethnic minorities were the Achilles heel in the body of
Nationalism. Cluster principle shows how impossible
Nationalism is at heart. How can one divide mankind into labels?
If Nationalism goes about to create a nation instantly there shall be
cluster of divisions by the same argument that shall be on ethnic, sectarian lines.
Here we see a paradox that works even this day.
Hungarian nationalism of Kossuth was generously liberal;
in combating the national feelings of the Slavs and other minorities
in their midst the Hungarians were as illiberal
as nationalists elsewhere. Do we not see this even today with migrant crisis that is
facing Europe?
Earlier the Enlightenment and the French Revolution had declared the rights of man.
It is an idea and holds “Men are born and remain free and equal in rights.”
This nationalism as shown in the US is of a group who wants to rewrite the idea from
their faulty sense of history. Slavery was in their past and they even lost a war fought
for the principle of equality. Yet all they have is a dog whistle.”
Of what use was Enlightenment borrowed if by same token they could borrow from
Nazism despite of a war more widely engaged to be called a World War
And proved nothing short of stupidity?
