Is the Gulf of Mexico becoming the blood of a dead man as predicted in Revelation?
Seems news is all abuzz about the Gulf oil spill looking red and a bunch of people are looking at the Book of Revelation’s description of the sea becoming like blood. Here’s the technical discussion from Live Science for the scientific nerdy types: 
The oil slick that's spreading atop the Gulf of Mexico looks nothing like the black gunk and tar balls that have washed ashore.
The reason for the reddish coloring of the oil slick has to do with how the oil mixes with water, but scientists are puzzled as to why the colors coating the Gulf water are so bright.
"We believe that the reddish brown color is indicative of the formation of a water-in-oil emulsion, called a mousse," said Edward Overton, professor emeritus at Louisiana State University. "These [oil slicks] typically have colors other than black, but with this oil, the colors are fairly vivid."
He added, "We still don't know the exact cause of the color change but it probably as something to do with the water/asphaltene interactions."
Asphaltenes are residues from chlorophyll, the green pigment in plants, and they make up a component of crude oil.
Over hundreds of thousands of years, as plants died and sank to the bottom of the sea, along with other organic matter, they (along with their chlorophyll) mixed with mud and sand of the surrounding area. As more and more sediment piled on top, the resulting heat and pressure transformed the organic layer into kerogen, a dark and waxy substance. Over time, kerogen molecules broke up into shorter and lighter molecules made mostly of carbon and hydrogen (hydrocarbons). Depending on the mixture of liquid and gas, the result can be either petroleum or natural gas.
"We are trying to see if we can find the chromophores, but this is not a priority project because it doesn't affect the ultimate weathering of the oil," Overton told Life's Little Mysteries. A chromophore is the light-absorbing part of a molecule responsible for its color.
The scientists hope to see if other oils in the area have the same reddish color when mixed with water.
So, pretty much, they have no idea what is causing the oil to look like blood.
Here’s the scripture for the fundamentalist doom and gloom types:
And the second angel poured out his vial upon the sea; and it became as the blood of a dead man: and every living soul died in the sea. Revelation 16:3
Prophecy Dude doesn’t believe that what is happening in the Gulf is the direct fulfillment of the events in Revelation. A few things need to take place first before the time line reaches Revelation 16:3 and some of those big events yet to see fulfillment include the following: expansion of Israel, the rapture of the church, Ezekiel 38-39 war, rise of the Antichrist, building of the third temple, the desecration of the temple, implementation of the Mark of the Beast all need to be fulfilled way before we reach Revelation 16:3. So, if you are getting all jittery, take a deep breath. We’re not there yet.
But, (What a great place for the word “but” creating that neat transition that gets people’s attention.) God does love to forewarn, foreshadow, symbolize, and all those other similar things He’s done this from Genesis through Revelation. This devastating environmental destruction in the Gulf of Mexico that is now going on for months could very well be a small message for what is to come. Perhaps this explains how Revelation 16:13 will be fulfilled. When the earth gets to rocking and rolling with all those end time earthquakes, all those offshore oil wells could be broken open to spill forth black oil that mysteriously changes to appear as red as blood. Not even the scientists can ‘splain it like Lucy (international readers, Lucy refers to the USAs old I love Lucy television show). Those capped oil wells are just sitting there waiting. What better way for God to demonstrate the folly and frustration of man when He spills forth oil, the life-blood of mankind, into the sea. It could happen that way.
According to CBS News, an Associated Press Investigation shows, “More than 27,000 abandoned oil and gas wells lurk in the hard rock beneath the Gulf of Mexico, an environmental minefield that has been ignored for decades. No one - not industry, not government - is checking to see if they are leaking.”
Perhaps they are just sitting there waiting to be part of the plan in fulfilling Biblical prophecy that is sure to come to pass.
