We Have No Idea: A Guide to the Unknown Universe

“We Have No Idea” is a book about how we know like, less than 0.01% of the vast universe. A few examples of the things that we don't know about the universe that the book mentions are the Graviton, dark energy, dark matter, the list goes on for ever. The book is actually an adult book undercover, it uses "some" sort of trick into making people think it is a Kid's (Ok, fine, Teenager's) book. We Have No Idea also contains lots of puns that Kids might not understand, so I would recommend you to start reading it at the age of 9-15.
