Know if you know! 100 billion dollars made something that does not exist in the world – World

There are many man-made objects that cost millions of dollars and exist in the world that are still visible.

But there is one thing that has cost the most and is the most expensive project ever. You might be thinking that it might be a building like the Burj Khalifa, or a big plane or maybe even the Taj Mahal.

But here it is also worth considering that the most expensive man-made thing does not exist in the world.

The said expensive object is also listed in the Guinness Book of World Records for costing more than 100 billion dollars to build, making it the most expensive project of all time.

In addition, the International Space Station has several key components, including a research center for scientific experiments, power control modules to operate it, and advanced communications systems to stay connected to Earth. However, maintaining this technological excellence comes at a high price, costing millions of dollars annually in maintenance and repairs.
