It seems that a team of scientists from Australia has recently discovered something that might change the way people see the Pentagon forever. According to them, the stones that the constructors used for building the Pentagon are home to some 340-million-year old microbes. These microbes are older than the dinosaurs. Moreover, it seems that this stone, called oolitic limestone, is a very popular construction material. This led the experts to believe that many important buildings around the world, including the Empire State Building, host these microorganisms too. The name for this stone came from its spheres of calcium which resemble beads which, after being layered, formed the stone. The name scientists gave to them is ooids.
It’s interesting that the scientists previously thought that grains that rolled across the ocean floor collecting sediments actually formed these ooids. Now, Scientists at Australia National University are sure that these microbes are responsible for the ooids. According to Bob Burne, one of the experts conducting this research, what they did now was to propose a completely different origin story in what concerns these ooids. Their theory also explains their unique features. Moreover, thanks to this new research, the science world now is aware of the large role that microbes play on our planet. Also, on our every day lives.
The Pentagon is full of ancient microbes
In geologic history, oolitic limestone formed all over the world. Because of this, builders from ancient times and up until today have used it as a tough material for constructions. Burne said that this limestone is part of many important buildings which need to last for many years. This is because they are both lightweight and very strong at the same time.
For example, apart from the Pentagon and the Empire State Building, the Buckingham Palace, St. Paul’s Cathedral and the British Museum also contain it.
