Hole in space thought to be a billion light years wide

Tom Spears, CanWest News Service

Published: Saturday, August 25, 2007

OTTAWA -- Astronomers think they have found the biggest empty hole ever, a region of the universe a billion light-years wide where everything -- stars, dust, even dark matter -- is simply missing.

It's a discovery that lends itself to jokes about your favourite suburb, but Lawrence Rudnick, a University of Minnesota astronomy professor, is serious.

If someone crossed this area in a spacecraft, "travelling at the speed of light it would take about a billion years and there wouldn't be much to see. A pretty boring journey," he said.

Astronomers have known for years there are empty places in the universe, but they never expected one so big.

In our own neighbourhood, there would be hundreds of galaxies in a region this size, each of them holding a few hundred billion stars, as well as immense clouds of dust and gas.

There would also be dark matter -- mysterious stuff we can't see that still has mass, and exerts a gravitational pull.

Signals would be zooming all over the place -- X-rays, visible light, ultraviolet, infrared, all sorts of radio waves.

But when the Minnesota team looked for radio signals coming from this area south of the constellation Orion, there was just a lot of missing signal. As well, there's a spot where the "background" of microwaves from the very early universe is unusually cold, another indication that matter is missing.

He can't say the region is absolutely empty. Matter in this void may be like water in a desert: It's there, but very, very scarce.

But why is the empty space there -- or not there, if you look at it that way?

Through gravity, the astronomer says.

In the very young universe, matter was distributed very evenly all over, he says. "If the universe had stayed that way we wouldn't be here because you wouldn't have stars [or] galaxies if you didn't have clumping of material."

"Gravity makes things clump. But what that means is, it leaves holes behind."

I hope one day technology will advance far enough so that we can actually travel faster than light speed in space.  We'd definately avoid billion light year nothingness land.

What's crazy is that things are so far away in the universe that you're actually looking at things in the past.  If a person on a planet millions of light years away was looking at Earth with some sort of powerful telescope, he'd probably see dinosaurs even though they are long gone.

That just had some crazy implications...if humans ever mastered faster than light space travel they could potentially witness history occuring before their very eyes...That's trippy...very trippy.

Civil war reinactment?  No need!  Just travel a few hundred light years away from earth and boom, you can witness the real thing!!

Megatron ummm, light is the fastest thing in the Universe and you expect humans to devise something faster than that?

If someone to travel in a space kind of void above, which direction will he follow? The up & down and the left & right won't be available to facilitate the trained mind.
 
If he were travelling with the speed of light therefore the nearest stop will take billion years to reach? Death is sweeter than that really.
 
The structure of the current human mind is not designed to accomodate long memories that are accumulated in long life. Memories are the main component that make human as we know it. Without it we are just mere flesh and blood. And billion years of memories need a gigantic storage that you can't imagine in size and in complexity. Those data will bury his identity that make him/her a human that declare "I".
