Time waits for nobody, it just keeps on passing. In fact, our lives are so ruled by time, imagine living a whole day without keeping track of it! It's like a never-ending river carrying us all along, moving us from the past, to the present and on into the future. It's really awesome when you stop to think about it.
Greenwich Mean Time is still calculated using the sun and math! Time for some species is very different: Greenland sharks can live for over 400 years while a mayfly for only a few hours. Black holes could be the key to time travel. They could transport you to a different universe. There's more to time travel than what you see in the movies!Everything is related to time. Maybe one day we will be able to travel back to the past. Would we be able to change it? Imagine, if you fall through a black hole--some scientists believe you could end up in another universe! With over 100 full-color illustrations, this beautifully bound book is as eye-catching as it is fascinating. It's a perfect gift for curious young minds and budding scientists.
