Albert Einstein said his first ideas about relativity came from looking in the mirror as a teenager and wondering what it would be like to travel on a beam of light. This is the story of that journey. Journey by Starlight follows an imaginary recreation of Albert Einstein, and his traveling companion through space and time as they travel on a beam of light from a star over 3,000 light years away to Earth. Along the way, Einstein explains the science behind everything from the origins of the universe to the meaning of life, relativity, black holes, quantum mechanics (for beginners), climate change, evolution vs. intelligent design, and how the brain works, all delivered in fun, easy-to-understand, bite-sized chunks.
