Caught in the light
Cornelia Parker’s installations are all lit in a very simple, stark way… which makes them tricky to photograph.
This piece is called Cold Dark Matter: An Exploded View.
Given the difficulty of capturing the subject, I decided to concentrate on the shadows being cast on the wall. By the time I was taking this shot, the exhibition was getting quite busy, and it wasn’t feasible to exclude all of the people. So, I decided to make a virtue of including someone in the shot.
I was pleased to capture this woman’s face as she looked up and caught the bright light on her face. Frankly, this was more opportunistic than planned. But… I’ll take it!

The Museum of Contemporary Art (MCA) features Cornelia Parker's Cold Dark Matter. Can't be too many installations thirty years old still doing the rounds. This was a garden shed exploded by the British Army. The shadows thrown by the light bulb at centre are great and it still feels like it's exploding.

from Wikipedia (shortened):
The Einstein Cross QSO 2237+0305 is a gravitationally lensed quasar found in Pegasus, positioned directly behind Huchra's Lens ZW 2237+030. It is quadruply imaged, forming a nearly perfect cross, with the lensing galaxy at its center.
The quasar is located about 8*10**9 light years from Earth, while the lensing galaxy is located at a distance of 0,4*10**9 light years.
A gravitational lens is formed when the light from a distant, bright source (such as a quasar) is "bent" around a massive object (such as a cluster of galaxies) between the source object and the observer. The gravitational lensing effect is one of the predictions of Albert Einstein's general theory of relativity (GRT/ART).
The Einstein field equations (EFE) are the core of general relativity theory. The EFE describe how mass and energy (represented in the stress-energy tensor T) are related to the curvature of space-time (represented in the Einstein tensor G). In index notation, the EFE reads as follows:
G(a,b) + L*g(a,b) = (d/c**4) * T(a,b)
where g(a,b) is the metric tensor, L the cosmological constant, c the speed of light in vacuum and d is 8*pi*(gravitational constant)
The EFE, being non-linear differential equations for the metric, are often difficult to solve. There are a number of strategies used to solve them. For example, one strategy is to start with an "Ansatz" (educated guess) of the final metric, and refine it until it is specific enough to support a coordinate system, but still general enough to yield a set of simultaneous differential equations with unknowns that can be solved for. Metric tensors resulting from cases where the resultant differential equations can be solved exactly for a physically reasonable distribution of energy-momentum are called exact solutions. Examples of important exact solutions include the "Schwarzschild solution" (BHS) and the "Friedman-Lemaître-Robertson-Walker solution" (BBS)
The cosmological constant L (i.g. Lambda) was re-established (after eliminated by Einstein in knowledge of Friedmanns solution) for the explanation of the "accelerated expansion of the universe" in the "Lambda-ColdDarkMatter" (LCDM) concordance model ..

Carlos Frenk talking about experiments currently under way to detect cold dark matter:
1) Direct detection in deep, underground mines such as Boulby in north east England.
2) Make it in laboratory: Search for supersummetry at LHC
3) Indirect detection through cosmic radition: Fermi gamma-ray telescope

Professor Carlos Silvestre Frenk from Durham University in England is a Mexican-British cosmologist and a Fellow of the Royal Society, focusing on understanding dark matter, which was the theme of his talk at the Jubileum Conference of the Norwegian Astronomy Society in Tromsø, Norway, on March 2nd 2013.
Frenk mentioned that there are two experimental reasons for the existence of dark matter, though no experiment has actually detected a dark matter particle yet:
1) Gravitational lensing shows that galaxies must have much more matter than their visible light indicate in order to bend light from even more distant galaxies so much.
2) Rotation of stars in galaxies are too fast for regular gravity to be sufficient, dark matter is needed to keep the stars in their orbits and not fly off on a tangent.
According to Frenk, dark matter also helped to create all the ordinary matter structures (i.e. the galaxies) by forming templates for the ordinary matter to stick to.
Carlos Frenk shows a pie chart of what astronomers currently believe our universe is made of:
4% normal matter
21% dark matter
75% dark energy
Hence, 96% of the Universe is made out of stuff we know nothing about!
