The Tokyo Tower of Babel is the tallest proposed building ever. First proposed in 1992, it was inspired by the biblical Tower of Babel, a structure that could reach the heavens. This Tower of Babel would reach 10 kilometers in height, with a main purpose of population support, having as many as 30 million people living in this area. Mainly made out of steel, it would most likely take about a hundred years to complete and would cost 3 trillion yen (27.218 billion USD). Because of the sheer size, it was soon cancelled. However, if the tower was made, how long would it last in a life after people?
1 Day After People
Built on land, the Tokyo Tower of Babel stands 10 kilometers high into the sky, with many of its floors made for several different purposes. Being on land, it doesn't face the risk of faster corrosion, like the Shimizu Mega-City Pyramid or X-Seed 4000. Its design, mainly made of "suction cup-like" structures on land, connecting to the upper floors that are similar in design, which connect to the higher floors, all kept safe by a tall, wide support in the center, making high stability for a tall structure like this. For now, it stands as the tallest building on Earth, but for how long?
5 Days After People
The many purposes of the floors were mainly for housing and commercial use. The 1-3 km parts were designed for office and hotel facilities, while the 3-6 km floors were for education, administration, and leisure facilities. The highest parts are held for industrial, experimental research, and base facilities, while the top part is made for space exploration and solar energy. The underground portion is made for parking, power generating, and power plants. Because of the excess energy gathered by those, the Tokyo Tower of Babel is still powered on after 5 days, while most other buildings around the world fall to the darkness. The building itself faces many challenges, despite it being energy efficient. The Tokyo earthquakes imminent in the city can cause damage to the tower, as well as possible fires and storms, which can damage tower supports. However, it won't have to worry about accidental airplane collisions, as man no longer control the skies.
1 Month After People
After a month of surviving, the tower is already starting to face problems. The highest parts of the tower face collisions from asteroids or space debris falling down to Earth, as 10 kilometers up isn't enough to have space debris or asteroids orbit the Earth, as the tower only barely reaches the top of the troposphere, being taller than Mount Everest. Fortunately for it, asteroids have a one time chance to collide. However, when they do, the tower has a risk of the falling parts to hit the rest of the tower below. Strong winds high in the troposphere can cause the windows above to break as well. Now, the generator is starting to malfunction, without human assistance. The power plants have started to deactivate without the help of man as well. Without one power source, how long can the solar panels keep the Tokyo Tower of Babel on?
10 Months After People
As the months pass by, the Tokyo Tower of Babel is relatively unchanged. Although many of its windows have now broken, the structure itself hasn't had much damage. However, the exposure of the inside to the nature outside has the natural world starting to invade the tower. Plant life invades the bottom part, along with many animal life. Birds rest in the floors at around a kilometer high or lower. Over time, they might start to adapt and live higher and higher up the tower.
5 Years After People
A massive earthquake hits Tokyo, causing some parts of the steel-made suction cup structures to break. Although that won't do much now, they will have an eventual effect later on. Meanwhile, the many homes, offices, educational and leisure facilities are also under attack. The high winds above are devastating the interior. The occasional typhoon that strikes the place, fills most of the floors with water, even the upper areas. However, the highest parts are safe from the typhoon's destruction. That spot is reserved for the falling asteroid and space debris that may come crashing down on the tower.
15 Years After People
Holding on, the tower is still powered and is one of the last places on Earth to stay that way. However, the solar powered panels have run out. Despite being in a higher altitude, it still takes time until it gets dirty and may sometimes get struck by falling space debris. In a matter of 5 hours, the Tokyo Tower of Babel finally plunges into the darkness, the last spot in Tokyo to do so. Many of the houses are starting to fall apart, as well as many research areas above.
60 Years After People
Nature is continuing to invade the Tokyo Tower of Babel. As many of the housing in the first floors have fallen apart, the steel framework itself is corroding. Slowly, but surely, the steel will soon start to fall apart, which will destroy much of the support of the tower. However, as of now, the tower still stands fine. All of a sudden, a falling asteroid about 10 meters wide crashes into the top part of the tower, destroying a major part of both the fading solar panels and space development center. Although it destroyed much of the top part, the upper tower hasn't reached its breaking point just yet.
100 Years After People
Over time, the years have destroyed all of its windows, and the lower 1 kilometer has succumbed to nature. A large tsunami off the coast ravages the lower levels of the Tower of Babel, destroying the remains of housing and parking that once resided there. Many of the suction cup-like structures have now fallen apart. Many of the interior have been destroyed, except for a few bits of interior that were remained. The top portion of the tower has finally fallen apart due to gravity, ever since an asteroid struck it many years ago. The steel is able to hold it together for now, but will eventually turn its back on it. The rising levels of water in Japan have started to reach the tower as well, which will most likely cut short its expected survival at this point.
300 Years After People
The lower orbs that are made out of steel have corroded to the point of collapse. Plant life and the flooding waters have ruined the steel to the point and now, they fall to the waves, no longer able to keep their shape. A typhoon ravages the tower, with lightning striking many parts, causing them to fall apart. Despite its size and design, the Tokyo Tower of Babel, based on its current state, won't last a millennium.
500 Years After People
Despite the steel corrosion, the plant life has partly preserved the steel under its roots and leaves from nature for a while. The upper parts, although safe from the waves, aren't safe from this plummeting asteroid. As it crashes into the upper layer, it collapses another part, destroying about a kilometer of height, and further weakening the stability of the Tokyo Tower of Babel. The center has also started to fall apart, but at a much slower rate. Being ravaged by earthquakes, tsunamis, storms, and asteroid collisions, how much longer can the tallest tower in the world last?
750 Years After People
The Tokyo Tower of Babel has been clinging on for 750 years now, with much of the steel peeling away from the center, because of heavy corrosion and water levels. All that's left of the tower now are only portions of the once hospitable rooms and sections that are attached to a tall, wide metal rod. Now, a mega earthquake destroys the last of the supports of the tower, causing it to topple in what would be one of the greatest collapses there ever will be. Its mass collapse destroys any nearby surviving buildings, such as the remains of DIB-200 and the Green Float. The collapsing remains of the tower also damages both the Shimizu Mega-City Pyramid and X-Seed 4000, but both of them still stand. The once tallest structure ever proposed, the tower that tried to reach for the heavens, now reaches the ground and is stuck to corrode away, finally ceases to exist.
