U.S. astronomers discover huge void
Seldom has someone so much so looking nothing like Lawrence Rudnick. The U.S. astronomer discovered billions of light years away from Earth, a vast area of yawning emptiness. The previous theories make to the creation of the universe worthless, he says.

Washington astronomy professor Lawrence Rudnick
really has not found anything. This, however, quite extensive: "The biggest nothing in the universe," he calls his discovery proud.
His team from the University of Minnesota discovered six to ten billion light years away from us with a Radioteloskop a huge area - and is simply a: empty. The region was the astronomers have noticed before, because the cosmic background radiation is very weak here - the area that is "colder" as astronomers say.
A billion years in the void
The hole lies southwest of the constellation Orion, says Rudnick. And to give an idea of the gigantic size, he makes the following statement: If you travel with the speed of light, the sun reached in eight minutes and in some years, the nearest star, he says. "If they fly into the hole but it would take a billion years until they could rely on the other side."
This is really unimaginable. And with recent models not to . Explain Nevertheless, going from Minnesota astronomers believe the right not to have observed and measured.
only one explanation: "pure emptiness"
His team did it by physically expected, says Rudnick. What is necessary so that the cosmic background radiation decreases in such a way as observed? Your answer was clear: "pure emptiness." Perhaps there was once a star here or a galaxy there, but by comparison with the surrounding area is actually empty. Whether they were absolutely sure? "No," says Rudnick. Many scientists would not like the idea so much absolute void and they will submit counter-proposals, he said. "But that's exactly the great thing about our research."
Lawrence Rudnick himself speaks of such a big surprise that the possible scientific consequences were not yet in sight: "It's too early to tell." But the recent theories on the evolution of the universe - with clusters, superclusters, galaxies - did not match their observations. The consequences were far-reaching: "We will have to change our ideas about the formation of structures in the universe well."
