The Petronas Towers are currently the tallest twin buildings in the world, They also hold the record for the highest skybridge ever built branching between the 41st and 42nd floors. The buildings are constructed of central cores of concrete, as Malaysia does not have an indigenous steel industry. But how long will this symbol of Malaysia last?
75 years after people: The steamy tropical sun has corroded a part of crucial steel under the skybridge, causing it to buckle and turn the bridge into a down-only elevator. Now, the twin towers are forever seperated.
500 years after people: Possibly the tallest structure still standing on Earth, the steamy sun has destroyed the structure's exterior. Finally the weakened concrete fails at the top, and the building's crumble in on each other.
