The Fermi Paradox: Where are all the Aliens? (English Edition)

Humanity has been captivated by the concept of aliens for a long time. It has worked its way into our culture but still remains a scientific curiosity. Our hypothesises predict that the Universe should be full of aliens, but we still haven't found any conclusive evidence. Why is that? What are the limitations? If aliens exist, why after so much time, have we not detected them? In this book, I discuss the possibilities and suggested solutions to this paradox which also says a lot about us, our behaviour and our future.
