How small can you feel?

I've been interested in astronomy for a while now, and discoveries like this continue to completely puzzle me.

"WASHINGTON (Reuters) - A giant hole in the Universe is devoid of galaxies, stars and even lacks dark matter, astronomers said on Thursday.

The team at the University of Minnesota said the void is nearly a billion light-years across and they have no idea why it is there.

"Not only has no one ever found a void this big, but we never even expected to find one this size," said astronomy professor Lawrence Rudnick.

Writing in the Astrophysical Journal, Rudnick and colleagues Shea Brown and Liliya Williams said they were examining a cold spot using the Wilkinson Microwave Anisotropy Probe satellite, and found the giant hole.

"We already knew there was something different about this spot in the sky," Rudnick said. The region stood out as being colder in a survey of the Cosmic Microwave Background -- the faint radio buzz left over from the Big Bang that gave birth to the Universe.

"What we've found is not normal, based on either observational studies or on computer simulations of the large-scale evolution of the Universe," Williams said in a statement.

The astronomers said the region even appeared to lack dark matter, which cannot be seen directly but is usually detected by measuring gravitational forces.

The void is in a region of sky in the constellation Eridanus, southwest of Orion."

The fact that there is no dark matter in this void is completely mind-boggling.
Dark matter is hypothetical matter of unknown composition that does not emit or reflect enough electromagnetic radiation to be observed directly, but its presence can be inferred from gravitational effects on visible matter.
Dark matter accounts for the vast majority of mass in the observable universe.
The lack of dark matter means that there is literally nothing in this area.

To clarify just how big this void is:
A light-year is approximately equal to 9,460,730,472,580.8 km.
It takes one billion light-years to cross the void.
So:

1000,000,000 x ,460,730,472,580.8 = 460730472580800000000

The mean circumference of Earth is 40,041.47 km.
Now imagine 460,730,472,580,800,000,000 km of absolute nothingness.
It's enough to make you feel more than a little uncomfortable.

As someone once said, what we can observe of the Universe is like trying to see an elephant by standing two inches from it with a magnifying glass.
Standing two inches away from this elephant and looking at it through a magnifying glass, we have managed to see an embodiment of pure nonexistence spanning across an area much larger than anything we could possibly experience.
What else is out there?
