Something may be out there. Way out there.

On the outskirts of creation, unknown, unseen “structures” are tugging on our universe like cosmic magnets, a controversial new study says.

Everything in the known universe is said to be racing toward the massive clumps of matter at more than 2 million miles (3.2 million kilometers) an hour—a movement the researchers have dubbed dark flow.

The Story continues:

Commentary by Bob Ferrari:
Interestingly, as time goes on, we seem to uncover yet another wild layer to this Universe. From the long-standing “geo-centric” theory of the famous Greek astronomer Ptolemy in the 1400s which suggested an Earth-centric solar system with the Milky Way as the extent of the Universe – which held sway for over a century, to the Polish astronomer Copernicus who rightly set our solar system as a Sun-centric one, to Edwin Hubble’s discoveries with the aid of the 100 inch Hooker Telescope, that the Universe was “not only immeasurable, but also expanding more rapidly the further away from us”, to this most recent discovery of possible extra-universe “structures” tugging at components of our own Universe. It seems that as time goes on, we just may discover that not only are we “not alone” in this Universe, but there possibly may be “other Universes” as well… if String Theory gets it’s way….

There is a mathematical formula called Drake’s Equation that can be used to “predict”, more like guess, the number of active civilizations in just our own galaxy. This equation is:

N = N* fp ne fl fi fc fL

Play with the equation here:

Drake Equation interactive web page:

Based on this equation and some really “out there” guesses, it is estimated that there are 900 active civilizations just in our own Milky Way Galaxy. Multiply this number by the billions of galaxies that there actually are out there, and you get the picture as to the possibility of life in the known universe.

Never mind the mind-numbing theory that this story is suggesting that there is more to this Universe than what we can “see”. The possibilities are endless !!
