LONDON (Reuters) - An international team of astronomers has produced the first map of the universe as it was 11 billion years ago, filling a gap between the Big Bang and the rapid expansion that followed.
The study, published in the journal Astronomy & Astrophysics, shows the universe went through a phase roughly three billion years after the Big Bang when expansion actually started to slow, before the force of so-called 'dark energy' kicked in and sent galaxies accelerating away from each other.
Much is known about the immediate aftermath of the Big Bang from studies of its afterglow in the cosmic background radiation, and its accelerating expansion over several billion years can be seen with a look at the way distant galaxies are moving.
"Only now are we finally seeing its adolescence... just before it underwent a growth spurt," said Mat Pieri at the University of Portsmouth in Britain, one of the authors of the study.
Little is known about dark energy, and its counterpart dark matter, but astronomers argue the force must exist to account for the speed at which the universe is expanding. Together, dark energy and dark matter are believed to make up about 96 percent of the universe.
The new study supports the theory that dark energy was somehow created as the universe expanded, by detailing a period when gravity was winning the tussle and slowing the expansion.

Now that’s an old map.
Look! There’s Nebraska!
The headline makes it sound as if they found an 11 billion year old map. I’ll bet the paper is pretty brittle. :^)
I always look forward to reading these stories, but I wind up not understanding a darn thing they’re saying.
I did not know the frst map was produced 11 billion years ago!
The ink’s still drying.
The guy who made the map back then didn’t realize how old he was.
He was caught in one of those Vonnegutian Chrono Synclastic Infundibulum Thingys.
So it goes.
In the beginning there were grapefruits. And then they exploded seeding the ——— which resulted in an expanding universe. Amazing stuff.
I wind up not understanding a darn thing theyre saying.
I hear ya. We have lost some sharp astronomical assets here over the years that could chime in.. but hopefully a few are still around that can help us out. ;-}
Vonnegutian Chrono Synclastic Infundibulum Thing. That explains it, thanks.
Me too—I guess stuff like this is above my pay grade.....
That theorem leaves a bitter taste in my mouth and tummy.. altho some believe that the known universe used to be a tiny little thing, no bigger than a pea or so.. so a grapefruit is not entirely out of the running. lol
I hope they printed that map on a very large sheet of rubber, because the universe has expanded a lot in 11 billion years.
