Earth is almost 4.6 billion years old and still we (humans) don’t know atleast 1% of it’s hidden secrets. Scientists and Researchers were really trying hard to uncover some of those secrets and over the years they did manage to do so. But who knows whether they are really legitimate or not.

- Water on Earth is 97% salted and 3% fresh.
- A human can survive on outer space for 2 minutes without any protection.
- It took $150 billion to construct I.S.S (International Space Station), the most expensive man made object ever constructed.
