Light-Bending Microchip Could Fire Up Quantum Computers

Posted by in categories: computing, quantum physics, time travel

For the first time, scientists have achieved infinite speeds on a microchip. Although this advance will not enable faster-than-light starships, the light-warping technology behind this innovation could lead to new light-based microchips and help enable powerful quantum computers, researchers said.

Light travels at the speed of about 670 million miles per hour (1.08 billion km/h) in a vacuum, and is theoretically the fastest possible speed at which matter or energy can travel. Exceeding this speed limit should lead to impossible results such as time travel, according to Einstein’s theory of relativity.

However, in a way, researchers have overcome this barrier for decades. [Warped Physics: 10 Effects of Faster-Than-Light Travel].

Quantum computers: a time-travelling boost

Posted by in categories: computing, quantum physics, time travel

In general relativity, closed timelike curves can break causality with remarkable and unsettling consequences. At the classical level, they induce causal paradoxes disturbing enough to motivate conjectures that explicitly prevent their existence. At the quantum level such problems can be resolved through the Deutschian formalism, however this induces radical benefits—from cloning unknown quantum states to solving problems intractable to quantum computers. Instinctively, one expects these benefits to vanish if causality is respected. Here we show that in harnessing entanglement, we can efficiently solve NP-complete problems and clone arbitrary quantum states—even when all time-travelling systems are completely isolated from the past. Thus, the many defining benefits of Deutschian closed timelike curves can still be harnessed, even when causality is preserved. Our results unveil a subtle interplay between entanglement and general relativity, and significantly improve the potential of probing the radical effects that may exist at the interface between relativity and quantum theory.

In This Trippy Short Film, a Man Meets Every Possible Future Version of Himself

Posted by in categories: futurism, time travel

In Therefore I Am, the McCoubrey brothers create a compelling time travel mystery in just six minutes. It leaves you with questions, BUT in a good way.

Therefore I Am tracks a conversation a man has with future versions of himself, each one arriving slightly earlier than the last, each one with slightly different instructions for how to get to that point. You can even trace the loops—each one leads to the next. And yet, not a single one seems to have successfully avoided the event they’re trying to stop.

Time Travel & The Multiverse – Many Worlds: Many Timelines

Posted by in categories: cosmology, time travel

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.

Simulation Shows Time Travel Is Possible

Posted by in categories: computing, particle physics, quantum physics, time travel

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.

Time Travel Could Become Reality Sooner Than You Think

Posted by in categories: particle physics, quantum physics, space, time travel

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.”

Cambridge Physicists Find Wormhole Proof

Posted by in categories: energy, quantum physics, space, time travel

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.”

Physics-Astronomy: NASA’s Warp-Drive Solution for Faster-Than-Light Space Travel

Posted by in categories: materials, space travel, time travel

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.
