Where is the center of the universe?

Where is the center of the universe? Well, the answer is confusing: nowhere in particular and also in all...

To understand these things have to make one thing clear about the famous Big Bang: the famous big bang matter filled the empty space, in fact it was a very rapid expansion of space itself, which before the "bang" was fold completatamente on itself at a point of infinite density that scientists call unique . 

The universe extended omnidirectionally (and still does apace, as demonstrated in 1929 Edwin Hubble), so any point we choose to appear to be in the center.

It may be difficult to explain this to a child, so it's best to offer you a simple image itself can handle. If we think of the universe like a deflated balloon on which we have painted several points, we can tell our son that these galaxies represent. If we blow and fill the air balloon, each point on the surface will move away from the other points. Something happens to the space between the galaxies expands (like the rest of the universe) at an accelerating rate.

However, the galaxies remain more or less in size due to gravity, as you know is attractive. But if in the beginning the entire universe fit in a single point. Where was that place? Can we find it to determine that it was the mile above zero? Well, I'm afraid that that point was and still is everywhere.

How do scientists know? There is evidence for this assertion.

In case you did not know, the light did not appear immediately after the big bang, but some 300,000 years later. That light cannot be seen as primitive, but has left its echo in the form of radiation. Scientists call it microwave background radiation and fill the sky in any direction. No matter where you point to your ear antenna with electronics, will grasp that radiation everywhere.

When you want to see this fossil, for many the main evidence of the existence of big bang, turned the old analog grandfather television and tune manually a frequency which does not emit any channel. Do you hear that noise? Well, the 1 percent of that "snow" background radiation is captured by the antenna of the device.

Decades ago about how a telephone company in the United States found that noise in error and were not able to get rid of it. In fact, initially attributed it to pigeon poop on the antenna. Curiously, although they had no idea what it was, finding that earned them a Nobel Prize, but that are another story and tell it another day.
