I propose to start my investigation in Kansas.

Researchers have developed a simple technique that adds evidence to the theory that the Universe is flat.
Moreover, the method - developed by revisiting a 30-year-old idea - confirms that "dark energy" makes up nearly three-quarters of the Universe.
The research, published in Nature, uses existing data and relies on fewer assumptions than current approaches.
Author Christian Marinoni says the idea turns estimating the Universe's shape into "primary school" geometry.
While the idea of the Earth being flat preoccupied explorers centuries ago, the question of whether the Universe itself is flat remains a debatable topic.
The degree to which the Universe is curved has an effect on what astronomers see when they look into the cosmos.
A telescope on or near Earth may see an image of a celestial object differently from how the object actually looks, because the very fabric of space and time bends the light coming from it.
Christian Marinoni and Adeline Buzzi of the University of Provence have made use of this phenomenon in their technique.

Circular reasoning
The technique used in this study was first proposed in 1979 by researchers at the universities of Princeton and Berkeley in the US.
It relies on measuring the degree to which images of far-flung astronomical objects are a distortion of their real appearance. The authors originally suggested a spherical object would work.

I propose to start my investigation in Kansas.
Sloan Digital Sky Survey
http://www.sdss.org/
The 2.5-meter telescope at Apache Point Observatory, named the Sloan Foundation Telescope in recognition of the pivotal and generous support of the Alfred P. Sloan Foundation through all phases of the SDSS. All SDSS imaging and spectroscopy were carried out with the Sloan Telescope, equipped with a large format digital camera and fiber-fed spectrographs that measured spectra of 640 objects at a time. These facilities, together with some new instruments, are also being used for SDSS-III. You can see the Sloan Telescope in action in this vid eo from the American Museum of Natural History.

Isaiah 40:22 “[It is] he that sitteth upon the circle of the earth, and the inhabitants thereof [are] as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:”
Psalm 104:2 “Who coverest [thyself] with light as [with] a garment: who stretchest out the heavens like a curtain:”
I guess he should know.
Still an article about a whole lot of nothing. The pick two different assumptions than others hold and get the same results. Still, garbage in, garbage out.
If dark matter really existed, we would have a prediction of its existence based on the laws of physics. Since there is no theory of dark matter, why pretend it exists?
If the universe is flat, does it sit on the back of a turtle?
The Kansas State team was sure flat last night.
Now we know where she came from............or went to.................
What type of fabric is space and time made of? Is it washable, or should it be dry cleaned?
The laws of physics are our mathematical guesses at how the universe works. They are not fixed since we do not know exactly how the universe works.
They still don’t know, do they?
My, my.
Though it´s a little like Fermi´s famous question with regard to ETs: ¨Where are they?¨
Why can´t we sample this ¨dark energy¨ directly as it´s supposed to be everywhere?
(Thanks for posting this article ,btw. Great topics)
What does DARK ANTI-MATTER look like? Can we see it, and if not, why the heck not?
Just like we couldn't sample gamma rays 200 years ago or why we couldn't detect neutrino's a hundred years ago. They were everywhere and we didn't know it.
How many neutrinos do you see fly through your eyeballs each day?
Do you have a 'dark' hair-blower , or any 'dark' lights?
If not, then what do you need dark energy outlets for?
Is it the name that bothers you? Because we can call it 'magic pixie dust', if people will just quite demanding that scientists actually produce some.
