I have bad news for you. You don't matter. Not very much. Not really at all. The darkness, that's what matters.
Many folks have heard of Dark Matter and Dark Energy. Most folks, however, can't tell you anything about them. They're dark. They're lurking out there. That's about it.
They're too important to leave at that. So, let's look at the "whys" and "wherefores" of both the Dark Duo. With today's post, I'm going to begin this exploration with a simple fact and its cosmic (literally) interpretation.
A member of the Free Syrian Army looks at the valley in the village of Ain al-Baida, in Syria's Idlib province, near the Turkish border, in December. Syrians fleeing the fighting in their country are flowing out across the border with Turkey, but opposition fighters say very few weapons are flowing in.

Members of the Free Syrian Army stand guard near the village of Ain al-Baida. The opposition says most of its weapons come from within Syria.
In a nondescript apartment room in Turkey, just across the border from Syria, clouds of cigarette smoke drift toward the ceiling as Syrian opposition activists ponder how to keep people and supplies moving across the border.
Abu Jafaar is the alias of a Syrian smuggler who has been dodging Syrian army patrols for the past several months.
Almost 25 years since the first organic farm took root in Hong Kong, the appeal of organic food is finally catching on. But restaurateurs, chefs, suppliers and organic experts say scant supply is leaving consumers hungry for more, and what is available still costs too much.

The JPAC report also states that the younger sailor had good oral hygiene.
In 1862, the USS Monitor — a Civil War-era ironclad warship — fought one of the world's first iron-armored battles against the Confederate ironclad CSS Virginia. Less than a year later, a violent storm sank the Union ship off the coast of Cape Hatteras, N.C. The wreck was discovered more than a century later, and subsequent searches have turned up more than just a crumbling ship — they also found the skeletons of two of the Monitor's sailors in the ship's gun turret.
