The Book of Possibilities is about the wonders of the world we live in. Come explore it with me!
The world's oceans cover seventy percent of its surface. Not only that, but it's a three dimensional world unlike the thin crust of dry land we surface dweller inhabit, so the actual space available undersea is even greater. It's no wonder we're fascinated by what all that water may cover.
Not long ago, underwater archaeologists discovered a wealth of statues and buildings hidden in the harbor at Alexandria - the remains of the Palace of Cleopatra. Here the famous queen entertained both Julius caesar and Marc Antony.
As a tourist to modern Egypt, you can tour the area in a glass-bottomed boat to see the wonders only a few meters under the surface, or dive among them yourself.
The area sank beneath the waves probably over a thousand years ago in a combination of earthquakes and storms. Now, the only way to visit Cleopatra's royal marina or the island of Antirrhodos, which was reserved for the queen's personal use, is to follow them into the depths.
The sea has claimed boats, planes, whole cities - perhaps even an entire continent, if the legends of Atlantis are true.
And it attracts treasure hunters, archaeologists, and biologists with its seemingly endless wonders.
Florida-based Odyssey Marine Explorations is in the shipwreck finding business. They'll even let you own your own piece of sunken treasure. One recent find, the sidewheel steamer SS Republic, yielded more than 51,000 coins, many of them rare. The total retail value of the coins may exceed $75 million.
The island of Thera in the Mediterranean vanished almost completely beneath the waves in a spectacular volcanic eruption around 1600 BC, altering the world's climate, and wiping out the Minoan civilization on Crete. Some modern theories, comparing recent finds on Thera with ancient Egyptian legends, suggest that it may be the basis for the legendary continent of Atlantis.
An old Dutch legend tells of the town of Saeftinghe, cursed by a merman to fall into the see, whose bells still ring out on foggy days, a call for help from a doomed world.
Jules Verne's classic "20,000 Leagues Under the Sea" doesn't seem so far fetched when you consider just how little we know about even what humans have lost beneath the oceans, much less what lives there in the depths.
