Scientists offer information on 'dark matter'
Scientists have discovered that axions can have mass between 50 and 1500 micro electron volts, that is, some ten billion times lighter than the electron. This computation has been published in the journal Nature. These calculations were done numerically using a (Bluegen/Q) super computer, JuQueen, housed in the Julich Supercomputer Centre in Germany.
Dark matter is known because of its weak interaction with matter and also as it is difficult to detect. Well rapidly rotating galaxies stand as its indirect proof. These galaxies cannot be held together merely by the gravitational pull of the matter they contain. There has to be an invisible stuff ‘dark matter’ to prevent them from flying apart with the force of their own energies.
Several particles have been hypothesized constituting dark matter- both massive as well as light weight – but none of the experiments have detected any such particle so far, directly.
Axions are particles proposed by extending quantum chromodynamics (QCD). The theory that describes “strong interactions,” the way quarks and gluons bond to form matter particles such as protons, neutrons etc. Though there are experiments to study them (for example: the Axion Dark Matter Experiment, ADMX) , there has been no real control on these until now.
The work sets a mass bound on the axions. And according to this, there should exist ten million such particles for every cubic centimeter of the universe. And also because axions occur in clumps there should be nearly a trillion axions per cubic centimeter in our galaxy, Milky Way.

( Albert Einstein - The Merging of Spirit and Science)
The most beautiful and most profound experience is the sensation of the
mystical. It is the sower of all true science. He to whom this emotion
is a stranger, who can no longer wonder and stand rapt in awe, is as
good as dead. To know that what is impenetrable to us really exists,
manifesting itself as the highest wisdom and the most radiant beauty
which our dull faculties can comprehend only in their primitive forms -
this knowledge, this feeling is at the center of true religiousness.

My
religiosity consists in a humble admiration of the infinitely superior
spirit that reveals itself in the little that we, with our weak and
transitory understanding, can comprehend of reality. Morality is of the
highest importance -- but for us, not for God. (Albert

Apr 12, 2015 - Brits among the least religious in the world: UK comes 59th in poll of 65 countries after only 30% of population say they have a faith.
According to Richard Dawkins, a distinction between agnosticism and atheism is unwieldy and depends on how close to zero a person is willing to rate the probability of existence for any given god-like entity. About himself, Dawkins continues, "I am agnostic only to the extent that I am agnostic about fairies at the bottom of the garden."[102] Dawkins also identifies two categories of agnostics; "Temporary Agnostics in Practice" (TAPs), and "Permanent Agnostics in Principle" (PAPs). Dawkins considers temporary agnosticism an entirely reasonable position, but views permanent agnosticism as "fence-sitting, intellectual cowardice".[103]
A
surveyed list has been made of the top twenty countries that hold the
highest number of individuals who are said to be either atheists, or
agnostics. However, the given numbers do not necessarily constitute the
exact number of people who claim to be non-believers in God. For
example, out of people who tool the survey in Estonia, 49% of people
claimed that they do not believe in God, but only 11% called themselves
atheists.
