All of these Wonders (and traditional lists of the Seven Wonders of the World) only include human-constructed or developed Wonders and thus natural features of the planet are not included. If you have comments about this list, please add your comments on the blog.
Egyptian PyramidsThe Great Pyramid of Giza, built thousands of years ago, is the only ancient Seven Wonders of the World that still remains. The Egyptian pyramids in general are an incredible architectural and technological achievement of ancient society and deserve a spot on this Wonders of the World list. The About.com Ancient/Classical History site has much more about the pyramids.
Space ExplorationFrom Sputnik 1 in 1957 to human space flight to lunar landings to space stations and the Space Shuttle, human exploration of space has been an incredible achievement. At the About.com Space/Astronomy site, you can explore this topic in great depth.
Channel TunnelCompleted in 1994, the Channel Tunnel (also known as Chunnel), connects the United Kingdom and France by train. It is a 31 mile-long (50 km) tunnel that took seven years to construct with crews working simultaneously from France and from the United Kingdom. Passengers and freight trains pass through the tunnel, easing transportation across (or under) the English Channel.
