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.

What sins of the future are you committing right now? — By David J. Hill SingularityHub

Posted by in categories: ethics, robotics/AI, time travel

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

New Book: An Irreverent Singularity Funcyclopedia, by Mondo 2000’s R.U. Sirius.

Quoted: “Legendary cyberculture icon (and iconoclast) R.U. Sirius and Jay Cornell have written a delicious funcyclopedia of the Singularity, transhumanism, and radical futurism, just published on January 1.” And: “The book, “Transcendence – The Disinformation Encyclopedia of Transhumanism and the Singularity,” is a collection of alphabetically-ordered short chapters about artificial intelligence, cognitive science, genomics, information technology, nanotechnology, neuroscience, space exploration, synthetic biology, robotics, and virtual worlds. Entries range from Cloning and Cyborg Feminism to Designer Babies and Memory-Editing Drugs.” And: “If you are young and don’t remember the 1980s you should know that, before Wired magazine, the cyberculture magazine Mondo 2000 edited by R.U. Sirius covered dangerous hacking, new media and cyberpunk topics such as virtual reality and smart drugs, with an anarchic and subversive slant. As it often happens the more sedate Wired, a watered-down later version of Mondo 2000, was much more successful and went mainstream.”

What Sci-Fi Movies Get Right and Wrong About Time Travel

Posted by in category: time travel

By Roxanne Palmer and Julie Rossman — Slate
Time Travel in Movies_graphic

In movies, time travel methods are mostly explained along the lines of “something something plutonium something wormhole.” But physicists do have some idea of methods that might allow for actual time travel—though they might not necessarily prevent you from killing your own grandfather.

One trope in time travel science fiction is slightly plausible, if physically impossible—traveling faster than the speed of light. The crew of the U.S.S. Enterprise did this in Star Trek IV: The Voyage Home, by using the sun’s gravitational pull to accelerate their spaceship to super-light speed. If it were possible to travel faster than light (Einstein calculated it would take an infinite amount of power), it is theoretically possible for signals to be sent back in time; it’s questionable if the same method could work with people.
