Excerpt from This Book Is From the Future: A Journey Through Portals, Relativity, Wormholes and Other Adventures in Time Travel by Marie D. Jones & Larry Flaxman.

Time travel has enchanted and intrigued us since the earliest days of fiction, when authors such as H.G. Wells, Samuel Madden, Charles Dickens and Enrique Gaspar y Rimbau stretched and challenged our imaginations with images and tales of men and women who invented amazing machines and devices that could take them back in time, or forward into the future.

Because of the restrictions of light speed, and the paradoxes of going back to the past without damaging the future timeline, and a host of other obstacles and challenges, we, in fact, have remained stuck in the present.

Australian scientists created a computer simulation in which quantum particles can move back in time. This might confirm the possibility of time travel on a quantum level, suggested in 1991. At the same time, the study revealed a number of effects which are considered impossible according to the standard quantum mechanics.

Using photons, physicists from the University of Queensland in Australia simulated time-traveling quantum particles. In particular, they studied the behavior of a single photon traveling back in time through a wormhole in space-time and interacting with itself. This time-traveling loop is called a closed timelike curve, i.e. a path followed by a particle which returns to its initial space-time point.

The physicists studied two possible scenarios for a time-traveling photon. In the first, the particle passes through a wormhole, moving back in time, and interacts with its older self. In the second scenario, the photon passes through normal space-time and interacts with another photon which is stuck in a closed timelike curve.

According to scientists photons can travel through time. They already have simulated directing quantum light particles to the past for the first time in the history. University of Queensland scientists learned that a simulation of two wormhole-travelling photons might interrelate; signifying hopping through time is conceivable at smallest scales. Their study might help to comprehend how time-travel could be conceivable in the quantum realm. PhD student Martin Ringbauer spoke to The Speaker: “For the first, ‘photon one’ would travel through a wormhole into the past and interact with its older version. In the second, ‘photon two’ travels through normal space-time but interacts with a photon that is stuck in a time-travelling loop through a wormhole, known as a closed timelike curve (CTC).”

Tim Ralph, UQ Physics Professor, said: “We used single photons to do this, but the time-travel was simulated by using a second photon to play the part of the past incarnation of the time travelling photon.”

Calculations show that if the wormhole’s throat is orders of magnitude longer then the width of its mouth, it does indeed create Casimir energy at its centre.

Cambridge Physicists Find Wormhole Proof:-Physicists at the University of Cambridge have established a theoretical groundwork for the reality of wormholes, which are pipes that join two different points in space-time. If a part of information or physical object could pass through the wormhole, it might open the door to time travel or immediate communication through huge distances. “But there’s a problem: Einstein’s wormholes are extremely unsteady, and they don’t stay open long enough for something to pass over.” In 1988, physicists reached the deduction that a type of negative energy called Casimir energy might keep wormholes open.

The hypothetical solution established at Cambridge has to do with the properties of quantum energy, which conveys that even vacuums are teaming by means of waves of energy. If you visualize two metal plates in a vacuum, some waves of energy would be excessively big enogh to fit between the plates, meaning that the space-time among the plates would have negative energy. “Under the right circumstances, could the tube-like shape of the wormhole itself generate Casimir energy? Calculations show that if the wormhole’s throat is orders of magnitude longer then the width of its mouth, it does indeed create Casimir energy at its centre.”

Agreeing to state-of-the art theory, a warp drive might cut the travel time between stars from tens of thousands of years to only weeks or months. Harold G. White, a physicist and innovative propulsion engineer at NASA and other NASA engineers are working to regulate whether faster-than-light travel — warp drive — might soon be possible. The group is trying to some extent warp the course of a photon, altering the distance it travels in a definite area, and then detecting the change with a device called an interferometer.

In 1994, a Mexican physicist, Miguel Alcubierre, speculated that faster-than-light speeds were conceivable in a technique that did not deny Einstein by binding the growth and reduction of space itself. Under Dr. Alcubierre’s theory, a ship still couldn’t surpass light speed in a native region of space. But a theoretical thrust system he sketched out operated space-time by producing a so-called “warp bubble” that would inflate space on one side of a spacecraft and contract it on another.

Backwards time travel at faster-than-light speeds would involve the creation of spooky doubles of the time-traveling object, a new hypothesis proposes.

Odds are you’re a decent, upstanding person. You abide by the laws, pay taxes, and don’t rock the boat. You value security but not at the expense of privacy. Like the majority of people around you, you’re driven by self interest but not to the detriment of others. And if someone is clearly in need, you’ll try to help them, if you feel you can make a difference.

In other words, you’re a moral human being…or so you think. Read more
