Hunter believes that everything should make sense-until one night, while stargazing, he learns that the universe itself is missing something. Galaxies are spinning too fast, stars should be flying apart, and yet they remain held together by an invisible force known as Dark Matter.As Hunter explores this mystery, readers are guided through the fascinating discovery of Dark Matter, learning how it does not emit light or interact with ordinary matter, but reveals itself through gravity. Using clear analogies and vivid imagery, the story explains how Dark Matter bends light, forms the cosmic web, and helped shape the first galaxies in the universe.Hunter also discovers how scientists search for this hidden substance-deep underground, inside powerful particle accelerators, and with space telescopes that map the unseen. Along the way, he realizes that not all mysteries are meant to be fixed. Some exist to inspire curiosity, patience, and imagination.Blending science, wonder, and reflection, The Shadow Map invites young readers to embrace the unknown and see the universe in an entirely new way.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/96/401/619/1964016193_b.jpg", "price_data" : { "retail_price" : "14.99", "online_price" : "14.99", "our_price" : "14.99", "club_price" : "14.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
