The oldest part of the universe, more than 10 billion light years away, bursts with super-luminous quasars and diffuse aggregations of hydrogen gas. Anže Slosar, a cosmologist at Brookhaven National Laboratory in New York, wants to map that expanse in 3-D.
Slosar looks for and then plots patterns in the periodic density fluctuations of matter that coalesced after the big bang. Others have mapped this structure to six billion light years away by observing how galaxies cluster, but at the universe's far edges, galaxies are too faint to see.
To overcome this challenge, Slosar uses a new technique that many were skeptical would even work: Instead of plotting light visible to humans, he and his collaborators look at the shadows telescope in New Mexico enabled Slosar to produce the largest-ever map of the ancient universe's structure—between 10 and 12 billion light years away—which in turn gives scientists insight into what the universe looked like very soon after it began.that massive gas clouds create when they obstruct light from the faraway quasars. For the first several months, the data looked too messy to map, and Slosar stewed in constant panic that he would fail. It took a few rounds of mathematical tweaks to coax out an actual signal. But once he did, data on 14,000 quasars from the BOSS
"I thought, Well, this is [what] the universe actually looks like very far away," Slosar says. "I felt so good that I just opened a beer and stopped working for the rest of the day."

I refuse to assume that WE are at the center of the universe. Ok so he's looking 10 billion years out and seeing "the edge", in one direction, how far does the other 359 degrees go? I understand that the light from those targets are XX billions of years old, thus were emitted that may years ago, but still, it does not mean that they are that old. Just because light comes into my window from 20 feet away, does not mean the light bulb is 20 feet old. We are just now looking that far away, that doesn't negate the fact that either the light source was around longer or is newer. Besides, it's been proven that Light bends with gravity and slows down in the cold... They REALLY need to STOP using Light speed as a distance marker, it's out dated and as too much potential to be inaccurate. It's like measuring with a rubber band.

This guy turns me on.
This article is not suggesting or implying we are at the center of our universe. Our universe appears to be expanding (at an ever increasing rate of speed), in all directions without regard to your specific point of reference.
I am my center and all I need lives in me.
And when my tummy is empty, I go buy more food, lol.
