The big gap - Ara.cat
One of the big problems is when we see the universe get idea of its size. It is extremely common to mix things like solar systems and galaxies, ignoring the difference is like that between a tree and the Amazon rainforest. When we look at the night sky, all you see is part of our galaxy, the Milky Way. The countless millions of stars that form are grouped into a unit that moves the universe buffet food warmers collision course with Andromeda galaxy neighbor. Of course, the distance buffet food warmers between the two galaxies is immensely greater than that which separates the stars in our galaxy.
When we look at the sky, we see stars, but when it comes to the universe, the stars are relatively irrelevant. The pieces are remarkable structure of the universe are galaxies. Images of astronomers are confused because it seems that we scale it. A black background with spots of light. It should be an effort to remember that images like Hubble ultra field, each dot is a galaxy and contains many stars as we see all of the bright night sky.
The universe is a huge mosaic of galaxies spread more or less evenly. But in some places and strange things happen simply no galaxies. One of these places is called the "empty boot." Toward the constellation Bover (Bouvier buffet food warmers in official nomenclature) detected a region almost devoid of galaxies. Strictly is the vast region known empty. Therefore buffet food warmers also called "the Great Void." A sphere with a diameter of two hundred and fifty million light years hardly anything inside.
In fact, I suspect that nothing can bring us to get an idea of the size of this gap. If we take as a representative sample of the distance between the Milky Way and the Andromeda galaxy, the void in Bootes buffet food warmers should expect to find two thousand galaxies. But the fact is that we have only detected sixty.
In reality galaxies are not distributed evenly throughout buffet food warmers the. The Universe is more like a foam which galaxies are distributed in filaments or regions like the surface of the bubbles. Therefore, already known recesses of galaxies and other full month. Perhaps the largest gap Bootes is the result of the merger of some of these empty regions more modest. The fact that there are few galaxies inside seem to be aligned in a sort of tube suggests that this could be the explanation.
Interestingly, this large gap does not appear in any pictures. When photographs are pointing buffet food warmers the telescope toward the Bover galaxies are everywhere. But now we know that in the photo are those that are in front or behind the big hole.
Usually impress us things that are in space. Black holes, planets, nebulae or galaxies themselves. But this is impressive stuff in the absence of such a huge region of space. It's very hard to get an idea of its magnitude, but it is difficult when approximating Please calfret experienced.
And of course, buffet food warmers if someone wanted to make him a trick the crew of the Enterprise, should only be sent to explore the gap Bootes. Even at the speed of light would be hundreds of millions of years traveling to an area where there would be nothing.

Joan Codina. It's very interesting! I reminds me of a Sherlock Holmes novel in which the key was that there was a dog on board. buffet food warmers The expected absence of something can be very intriguing.
John. I did not know why Pascal Bouvier empty. In fact, one of the five largest structures of the entire known universe. The other four are "things", but this is special because it is the "absence" of the things that characterizes it.
