Lol, I loved the comment about the guy who thinks it's a precursor to the world ending. In the grand scheme of things, It's a somewhat common event, although, still spectacular. If the earth is 6 billion years old and has been covered by oceans for 2.5 billion years. Typical lifespan of an ocean is 100 million years, that's 25 oceans we've had on this planet. It's kind of like one of those baseball statistics "This is the seventh player in major league history to fly out while having his pants fall off"
Don't get me wrong, it's a massively cool article.
