Explanation:

Our Earth is not at rest. The Earth moves around the Sun. The Sun orbits the center of the Milky Way Galaxy. The Milky Way Galaxy orbits in the Local Group. The Local Group falls toward the Virgo Cluster of Galaxies. But these speeds are less than the speed that all of these objects together move relative to the microwave background. In the above all-sky map, radiation in the Earth's direction of motion appears blueshifted and hence hotter, while radiation on the opposite
side of the sky is redshifted and colder. The map indicates that the Local Group moves at about 600 kilometers per second relative to this primordial radiation. This high speed was initially unexpected and its magnitude is still unexplained. Why are wemoving so fast? What is out there?

A Bit of Fun...
The Ultimate Answer

According to The Hitchhiker's Guide to the Galaxy, researchers from a pan-dimensional, hyper-intelligent race of beings constructed the second greatest computer in all of time and space, Deep Thought, to calculate the Ultimate Answer to Life, the Universe, and Everything. After seven and a half million years of pondering the question, Deep Thought provides the answer: "forty-two." The reaction:

    "Forty-two!" yelled Loonquawl. "Is that all you've got to show for seven and a half million years' work?"

    "I checked it very thoroughly," said the computer, "and that quite definitely is the answer. I think the problem, to be quite honest with you, is that you've never actually known what the question is." 

Arthur Dent — as the last human to have left the Earth before its destruction, therefore the portion of the computer matrix most likely to hold the question — attempts to discover the Question by extracting it from his unconscious mind, through pulling Scrabble letters at random out of a sack. The result is the sentence "WHAT DO YOU GET IF YOU MULTIPLY SIX BY NINE."

    "Six by nine. Forty-two."
    "That's it. That's all there is."

Of course, 6 × 9 is 54, not 42. There are several possible interpretations of this...  Source

It is our theory that they made a mistake. It isn't 6 x 9 or even 6 + 9... The Universe loves simplicity... You simply join the two numbers together and the Answer to Everything is 69!

All the Universe is based on opposites, male/female, good/evil, negative/positive, darkness/light, in other words the Cosmic Ying Yang!
And now with the NASA Image above there is absolute proof of the Great Cosmic Ying Yang

Think About it!
