These are the Twin Towers of the World Trade Center.
Today marks the 15th anniversary of the terrorist attack in which two airliners crashed into the Towers and brought them down, leaving nearly 3,000 people dead.
But these pictures are of the Twin Towers in the TV Universe... from the Spring of 2010.
This is not the main Toobworld, Earth Prime-Time. It is an alternate TV dimension known by the 'Fringe' Science Unit as "Over There". It is the TV dimension which connects 'Fringe' both to 'Doctor Who' and to 'Sliders'. Among its differences from Main Toobworld (as well as the Trueniverse) is that former President John F. Kennedy and basketball player Lennie Bias were still alive (at least in that year); dirigibles were still a major form of transport in the skies; and the Golden Gate Bridge in San Francisco was blue, dubbed the Azure Bridge.
But the continued existence of the Twin Towers is the most striking, heart-breaking difference of all.
All of the televersions of those people would still be alive today in the Over There, barring any later accidents, murders, or deaths by natural causes. As the most trivial difference, any home movies from our world uploaded to YouTube in which those victims might have appeared would be different over there since they could now be included in them.
But unfortunately for Earth Prime and for Earth Prime-Time, they are all now lost to us. Had Superman actually existed in our world, and had still been alive in Toobworld, things might have been different. Sadly, 'tisn't, as Swanny Swanson would say.....
May they all rest in peace and that we always remember.....
