Big Bang and the Dark Side

This question on Creation remains unanswered. Scientists are still digging and searching and still coming with theories that need good grounds of proof.

Lately Science Daily issued a new article, which uncovered new research by astronomers in the Physics Department at Durham University suggests that the conventional wisdom about the content of the Universe may be wrong.

The research is based on observations from Wilkinson Microwave Anisotropy Probe satellite of the remnant heat from the Big Bang.

The last observation in 2001 showed that the ripples were about twice the size of the full moon or around a degree across.
This suggested the cosmos is made of 4% normal matter, 22% dark or invisible matter and 74% dark energy.


Dark Side

The new observation showed that the measurement of the size of the ripples are significantly smaller, which could imply that the dark matter and dark energy are not present after all.

In astronomy  and cosmology, dark matter is matter that is inferred to exist from gravitational effects on visible matter and background radiation, but is undetectable by emitted or scattered  electromagnetic radiation. Its existence was hypothesized to account for discrepancies between measurements of the mass of galaxies, clusters of galaxies and the entire universe made through dynamical and general relativistic means, and measurements based on the mass of the visible "luminous" matter these objects contain: stars and the gas and dust of the interstellar and intergalactic  media



Dark Matter

Dark matter is crucial to the Big Bang  model of cosmology as a component which corresponds directly to measurements of the parameters associated with Friedmann cosmology solutions to general relativity.


Scientists send beams of particles racing through underground tunnels in hunt for invisible material that makes up 84 per cent of universe's matter and binds galaxies 
 The world's largest and most powerful atom smasher has been restarted after an upgrade that could see it making scientific history for a second time.


Hadron Collider

Scientists plan to send two beams of high-energy particles racing through the Large Hadron Collider's 16.7 miles (27 kilometres) of circular underground tunnels after the project took a major step forward on Easter Sunday morning.
Two years ago, the team operating the £3.74 billion machine straddling the Swiss-French border astounded the world with the discovery of the Higgs boson, an elementary particle that gives other particles mass.

Now they have their sights set on an even more exotic trophy - dark matter, the invisible, undetectable material that makes up 84 per cent of matter in the universe and binds galaxies together yet whose nature is unknown. 
Energy can be converted into mass in accordance with Albert Einstein's famous equation E (energy) = M (mass) times C (the speed of light) squared. The more energy available, the more massive the particles that can be created. 
 The search for dark matter involves stepping outside the Standard Model, the all-encompassing theory that describes the particles and forces of nature that has stood firm for the past 50 years.

A "new physics" model of the universe called super-symmetry predicts that every known particle has a more massive partner - and one of these elusive super-symmetry particles might be the source of dark matter.

At a Cern briefing in Geneva last month, British scientist Professor David Charlton, from the University of Birmingham, who heads the Atlas detector team, said: "We're heading for unexplored territory. It's going to be a new era for science." 

Dark energy is or was the most popular way to explain recent observations and experiments that the universe appears to be expanding at an accelerating rate.



Space

Galaxies show signs of being composed largely of a roughly spherically symmetric, centrally concentrated halo of dark matter with the visible matter concentrated in a disc at the center.

Low surface brightness dwarf galaxies are important sources of information for studying dark matter, as they have an uncommonly low ratio of visible matter to dark matter, and have few bright stars at the center which would otherwise impair observations of the rotation curve of outlying stars.

Gravitational lensing observations of galaxy clusters allow direct estimates of the gravitational mass based on its effect on light from background galaxies.

What does this mean?

If dark energy exists, then it ultimately causes the expansion of the Universe to accelerate, and plays a central role in th structure formation and galaxy evolution.

If it does not exist, then the structure formation and galaxy evolution must have been made by another method or system Or God.....

So far there is no known proved method or system that has arranged the cosmos.
All what we have are theories.
Even scientists are skeptical if these theories could be applied or not.
Well.... It seems the theory of God is prevailing as constant amongst all other theories.

This would leave the open possibility that the religious arguments are after all true.

Scientists believe that the acceleration of the Universe began about 5 billion years ago.
But we have learnt in religion and Myth that time has no essence in creation, as it has no essence in other dimensions or other worlds...

Would it be possible that the 5 billion years scientists are talking about is in reality only 6000 years.. Adam Age?

It seems now all possibilities are wide open.

Will we know the truth?.... Who knows
