Physicist discovers 'paradox-free' time travel is theoretically possible
Time Travel True Stories |
As movies such as The Terminator, Donnie Darko, Back to the Future, and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe:
If we go back in time and stop our parents from meeting, for instance, how can we possibly exist in order to go back in time in the first place?
It's a monumental head-scratcher known as the "grandfather paradox," but a few years ago physics student Germain Tobar, from the University of Queensland in Australia, worked out how to "square the numbers" to make time travel viable without the paradoxes.
The future is NOW unless you can get back to the past. |
"However, Einstein's theory of general relativity predicts the existence of time loops or time travel – where an event can be both in the past and future of itself – theoretically turning the study of dynamics on its head."
What the calculations show is that space-time can potentially adapt itself to avoid paradoxes.
To use a topical example, imagine a time traveler journeying into the past to stop a disease from spreading – if the mission were successful, the time traveler would have no disease to go back in time to defeat. More + VIDEO
It’s fair to say that most scientists today will tell us that time travel is impossible. Three of today’s top physicists -- Charles Liu, Brian Green, and Michio Kaku -- all hold that time travel is, if not impossible, unlikely in the extreme.
However, one of the most brilliant minds of our time, physicist Stephen Hawking, disagrees -- although only partially. He believes that time travel is theoretically possible, but only into the future....
What do real people experience?

The opinion of science, however, has never stopped thousands of people around the world from reporting what they firmly believe are actual experiences of spontaneous time travel!Still others insist that time travel is not only possible, but they have already done it as part of top secret government programs.
Claims for time travel range from the highly flaky to the astoundingly believable. They are especially difficult to dismiss when time travel reports come from absolutely ordinary, rock-solid people who have nothing to gain by proclaiming they travelled in time.
Many people who report time travel experiences don’t necessarily believe it themselves. What happened to them was so strange, so unexpected, yet so real; they simply have no other good explanation for their experience.
Meet a number of such individuals in this book, most of their stories straight out of the headline of local newspapers. No doubt, on the one hand, a story or two will strike the reader as pure balderdash.
On the other hand, some of these cases of time travel are tantalizing and inexplicable. They also come with a certain amount of solid evidence, such as stopped clocks, frozen machines, and electromagnetic devices acting in unexplained ways.

Physicist and NASA scientist Tom Campbell said that scientific advances always "come from the fringe."
Thus, even if we consider some of these stories stepping dangerously "out there" onto that fringy edge, remember that many of yesterday’s fringe theories are today’s scientific fact.
At the very least, it doesn’t hurt to approach the idea of time travel with an open mind and a sense of wonder.
