this is an interesting development in space sciences

"The most exciting aspect of the work is that there is no external data that we plug in," Marinoni told Space.com, meaning that their findings aren't dependent on other calculations that could be flawed.

The researchers probed dark energy by studying the geometry of the universe. the shape of space depends on whats in it— that was one of the revelations of Einstein's general relativity, which showed that mass and energy (two sides of the same coin) bend space-time with their gravitational force.

cool its good to know we are continually refining our veiw of the universe
i cant get onto the host site nature.com to read the nov 25 th reveiw of the findings (its the 25 here in nz) so it might not be published yet but if some one has access can you post some excerts

Great find, I bet soon they will finally discover all fundamental forces effect space/time and vice versa.

Which plays into the self-configuring and self-recycling universe theory, BB/inflation/contraction/BB/inflation/contraction/etc.

The geometry of space-time can distort structures within it. The researchers studied observations of pairs of distant galaxies orbiting each other for evidence of this distortion, and used the magnitude of the distortion as a way to trace the shape of space-time.


i love reading about this sort of stuff
the age and state of moment of the univese

i imagine if shape and density are able to distort our veiw of them

these are the galaxies in binary used to make the observation



by compairing the doppler effect on two rotating binary galaxies some of the details of the distortion are reveailed

i think that a new understanding of shape and density of the universe could be fundamental
to understanding how it works on a micro/macro scale

and on the same day this news comes out.

German scientists create 'super-photon
Scientists in Germany have disproven assumptions that creating a "super-photon" was impossible, by finding a solution with a comparatively simple experiment.




dw world


A team of physicists, lead by the University of Bonn's Martin Weitz, have managed to create a Bose-Einstein condensate out of photons, or particles of light. This discovery could be used to develop better microchips for computers or more efficient solar energy technology, according to their research which was published in the journal Nature on Thursday.

Bose-Einstein condensates (BEC) were first proposed in the 1920s by Satyendra Nath Bose and Albert Einstein, who asserted that atoms, chilled to very near absolute zero, would take on quantum characteristics, so that the atoms "overlap, and behave as a giant meta-wave," or a sort of super-atom, wherein a collection of atoms all act in concert, Weitz told Deutsche Welle.

Not everyone in the field of quantum optics is happy with the term super-atom or super-photon though, such as Aephraim Steinberg, a quantum physicist at the University of Toronto.

the photon expermint showed


The experiment also made use of liquid dye pigment that cooled the photons down to room temperature while they were trapped between the two mirrors. When enough photons were pumped into this apparatus, a BEC state was observed "which appeared as a yellow peak in the middle and there the photons marched in step," Weitz said.

cool experiment
and simple too

cold photons and a focus point a bit of dye

So, now that Einstein says anti-gravity (cosmological constant, dark energy, etc.) exists... can we now get on with using it? Or will the science community label it as only an anomaly, and continue to ignore it - as not useful?

A geometric measure of dark energy with pairs of galaxies

Top of pageAbstractObservations1, 2 indicate that the expansion of the Universe is accelerating, which is attributed to a ‘dark energy’ component that opposes gravity3, 4. There is a purely geometric test of the expansion of the Universe (the Alcock–Paczynski test), which would provide an independent way of investigating the abundance () and equation of state () of dark energy5. It is based on an analysis of the geometrical distortions expected from comparing the real-space and redshift-space shape of distant cosmic structures, but it has proved difficult to implement6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18. Here we report an analysis of the symmetry properties of distant pairs of galaxies from archival data19, 20. This allows us to determine that the Universe is flat. By alternately fixing its spatial geometry at and the dark energy equation-of-state parameter at , and using the results of baryon acoustic oscillations, we can establish at the 68.3% confidence level that and .
