Book Description
Even the most reluctant readers will be fascinated to read about how twin astronauts Scott and Mark Kelly are a different age because Scott spent a year living on the International Space Station. This book looks at how time travel has been thought of from ancient times to modern day. It even discusses what humans might do if they could travel in time. From string theory to Einstein's theory of relativity, Heisenberg's uncertainty principle to the grandfather paradox, and wormholes to quantum physics, everything time travel related is discussed here in easy-to-understand language and complimented by vivid artwork on every spread.

Book Description
This book explores the idea of time travel from the first account in English literature to the latest theories of physicists such as Kip Thorne and Igor Novikov. This very readable work covers a variety of topics including: the history of time travel in fiction; the fundamental scientific concepts of time, spacetime, and the fourth dimension; the speculations of Einstein, Richard Feynman, Kurt Goedel, and others; time travel paradoxes, and much more.

Book Description
A Princeton astrophysicist explores whether journeying to the past or future is scientifically possible in this “intriguing” volume (Neil deGrasse Tyson). It was H. G. Wells who coined the term “time machine”—but the concept of time travel, both forward and backward, has always provoked fascination and yearning. It has mostly been dismissed as an impossibility in the world of physics; yet theories posited by Einstein, and advanced by scientists including Stephen Hawking and Kip Thorne, suggest that the phenomenon could actually occur. Building on these ideas, J. Richard Gott, a professor who has written on the subject for Scientific American, Time, and other publications, describes how travel to the future is not only possible but has already happened—and contemplates whether travel to the past is also conceivable. This look at the surprising facts behind the science fiction of time travel “deserves the attention of anyone wanting wider intellectual horizons” (Booklist). “Impressively clear language. Practical tips for chrononauts on their options for travel and the contingencies to prepare for make everything sound bizarrely plausible. Gott clearly enjoys his subject and his excitement and humor are contagious; this book is a delight to read.” —Publishers Weekly

Book Description
You have seen movies, you have read books and every time have thought whether you could do it too. The word ‘time travel’ itself brings a stir within and the fancies of what one could change if given the opportunity to go back in time or in the future. What might seem impossible for you has been tried and tested by many. They also have given many explanations of how time travel is possible. There are a number of questions that arise when something impossible like this is spoken of. This eBook is all about the history and crucial explanations of the possibility of travelling through time portals.

Book Description
We all travel in time. During the last year, I've moved forward one year and so have you. Another way to say that is that we travel in time at the rate of 1 hour per hour."We like the idea of time traveling because if we go back in time, many of us would like to change things to make the future better. And if you travel to the future, you'd want to come back with some wonderful discovery and share it to improve human life. So the desire to time travel is quite a positive fantasy to have," But the question is, can we travel in time faster or slower than "1 hour per hour"? Or can we actually travel backward in time, going back, say 2 hours per hour, or 10 or 100 years per hour?It is mind-boggling to think about time travel. What if you went back in time and prevented your father and mother from the meeting? You would prevent yourself from ever having been born! But then if you hadn't been born, you could not have gone back in time to prevent them from the meeting.The great 20th-century scientist Albert Einstein developed a theory called Special Relativity. The ideas of Special Relativity are very hard to imagine because they aren't about what we experience in everyday life, but scientists have confirmed them. This theory says that space and time are really aspects of the same thing-space-time. There's a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space.Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people.Say you were 15 years old when you left Earth in a spacecraft traveling at about 99.5% of the speed of light (which is much faster than we can achieve now) and celebrated only five birthdays during your space voyage. When you get home at the age of 20, you would find that all your classmates were 65 years old, retired, and enjoying their grandchildren! Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years.So, if your journey began in 2003, it would have taken you only 5 years to travel to the year 2053, whereas it would have taken all of your friends 50 years. In a sense, this means you have been time traveling. This is a way of going to the future at a rate faster than 1 hour per hour.Time travel of a sort also occurs for objects in gravitational fields. Einstein had another remarkable theory called General Relativity, which predicts that time passes more slowly for objects in gravitational fields (like here on Earth) than for objects far from such fields. So there are all kinds of space and time distortions near black holes, where the gravity can be very intense.In the past few years, some scientists have used those distortions in space-time to think of possible ways time machines could work. Some like the idea of "wormholes," which may be shortcuts through space-time. This and other ideas are wonderfully interesting, but we don't know at this point whether they are possible for real objects. Still, the ideas are based on good, solid science. In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built.

Book Description
The idea of time travel is one that never gets old. It has enthralled the imaginative, the serious, and the scientific for centuries. Your readers will learn the science behind the fantasy of time travel, the theories behind such an ability, and the inventions that are trying to get us to the past, and beyond.

Book Description
*Approved by national science authorities* ------ Is time travel possible or just science fiction? The concept of time travel, both forwards and backwards, has created an endless source of excitement and curiosity. In the realm of physics, it has been generally considered an impossibility, nevertheless, theories put forward by Einstein and further pursued by scientists such as Stephen Hawking and Kip Thorne indicate that such a phenomenon could indeed occur. As many of us have less and less time to contemplate physics, Lisa Visintainer brings the universe down to a language we can all understand while plunging into the exotic realms of time, wormholes, blackholes, antimatter, "arrows of time" and showing us the possibilities of real time travel physics. She offers a straightforward guide into this admittedly difficult topic, which tries to understand time and its possibilities for time travel. Unlike other publications that shy away from the entirety of relativity and similar topics, Time Travel Physics for Beginners embraces the complete unfamiliarity of most of the theories and logic associated with the topic. Lisa Visintainer provides crystal-clear explanations of, among other things, the principles of time travel, time machines (that are noncomparable with the common fiction ones), and its related paradoxes. Time Travel Physics for Beginners, a book approved by Austrian national science authorities, is considered to be one of the very few books offering plausible answers to big questions and is an excellent read for cosmos-interested people, which millions have been waiting for.
