Australian Scientists Prove Time Travel Is Possible

Some physicists are convinced that time travel is possible. A group of scientists from the University of Queensland, Australia, have simulated how time-travelling photons might behave; suggesting that, at the quantum level, the grandfather paradox – which makes time travel impossible – could be resolved. The study used photons – single particles of light – to simulate quantum particles travelling back through time. By studying their behavior, the scientists revealed possible strange aspects of modern physics.

“The properties of quantum particles are ‘fuzzy’ or uncertain to start with, so this gives them enough wiggle room to avoid inconsistent time travel situations. Our study provides insights into where and how nature might behave differently from what our theories predict,” said co-author Professor Timothy Ralph.

The Daily Mail explains:

In the simulation, the researchers examined the behavior of a photon traveling through time and interacting with its older self. In their experiment they made use of the closely related, fictitious, case where the photon travels through normal space-time and interacts with another photon that is stuck in a time-travelling loop through a wormhole, known as a closed timelike curve (CTC). Simulating the behavior of this second photon, they were able to study the behavior of the first – and the results show that consistent evolutions can be achieved when preparing the second photon in just the right way.

 
wormholes
Wormholes are theoretical tunnels that create shortcuts in space-time. A study in May from Dr Luke Butcher at Cambridge University argued that if a thin wormhole stayed open long enough, people could send messages through time using pulses of light, or photons.

Because of Albert Einstein’s well-tested theories of special and general relativity physicists believe time travel is possible. Special relativity posits that space and time are aspects of the same thing, known as the space-time continuum, and that time can slow down or speed up, depending on how fast you are moving, relative to something else. General relativity suggests that it would be possible to travel backwards in time by following a space-time path, i.e. a CTC that returns to the starting point in space, but arrives at an earlier time.

In 2012, physicists David Wineland and Serge Haroche shared the Nobel Prize in physicsfor demonstrating how “quantum weirdness” could not only exist at the subatomic micro-world level, but also show itself in the macro-world.

“The question of time travel features at the interface between two of our most successful yet incompatible physical theories – Einstein’s general relativity and quantum mechanics. Einstein’s theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules,” said Martin Ringbauer, a PhD student at UQ’s School of Mathematics and Physics and a lead author of the paper.

With several physical problems and paradoxes, is it really possible to go backwards through time? In a new BBC documentary, astrophysicist Stephen Hawking suggests that it simply isn’t possible to go back in time. And there’s not much to look forward to, either. Nonetheless, advances in quantum theories could perhaps provide some understanding of how to overcome time travel paradoxes.

Time Travel is Inevitable When You Mix the Natural and Magical Worlds

Time Travel is Inevitable When You Mix the Natural and Magical WorldsBy Wanda Luthman

How would you like to meet a real unicorn? Imagine riding on his back as he flies to the stars.

Well, Gloria, from “Gloria and the Unicorn” gets to do just that. However, her life doesn’t start out as happy. While giving birth, her mother died and Gloria was abruptly pulled from the womb. That’s why Gloria’s face is droopy on one side.

Unable to care for the child, her father gives Gloria to a children’s home where she overhears a conversation about herself that causes her pain to deepen. She is kept out of school to protect her from bullies, but all the young girl wants to do is learn to read.

But her life takes a turn for the better after her wish to meet a magical unicorn comes true.

Sir Louie, the kind unicorn, shows up and helps her to understand the truth and to believe in herself. He also teaches her to read in a magical way, a method that lets them travel into the stories.

So, you see, time travel is inevitable when you mix the natural world with the magical.

Sir Louie lives in Faralee—a land in which time doesn’t seem to exist. Fairies are his friends and all they do every day is laugh and play all day. But, something inside of him pulls him to Gloria.

You ask why? Well any child knows that a unicorn’s role in life is cheering up sad humans. The problem is how to travel across the time/space continuum from Faralee to Gloria.

Skipping ahead, Sir Louie finally meets Gloria and they jointly travel into the books they’re reading; trips that take them through the time/space continuum. This activity seems harmless enough but eventually they come to the attention of the Wicked Wizards of Malcadore. Their instinctive prime directive is to hate humans with magical powers.

The Wizards realize that Gloria’s powers could ruin them so they hatch a plan to capture Sir Louie and Gloria.

To find out how an unlikely duo, Gloria and Sir Louie survive the Wizards’ evil plans, I guess you’ll have to read “Gloria and the Unicorn”—a children’s book for ages 7-10.
