It has become a great challenge today to try to understand the universe around us. So far, we have gathered many ideas to the mysteries in our world, particularly on how planets orbit the Sun, why an apple falls from a branch to the ground and not moving upward, why the sky appears blue or the rising Sun looks red. The quest to solve all the secrets of the universe is definitely a very difficult challenge. Now that astronomers have directly got the existence of gravitational waves, ripples through space time itself, the last bit of Einstein's theory of general relativity has clicked into place. Despite spectacular recent progress, there is still a lot we don't know about our universe. We don't know why the Big Bang happened. We don't know what most of the universe is made of. We don't know whether there is life in space. We don't know how planets form, how black holes get so big, or where the first stars have gone. So many "no's" are not the biggest cosmic mysteries, today? The book provides recent information for a new dimension of scientific study of this challenging universe with our existing and available information in hand!
