In fact, we detect particles on the other side of the barrier that have made the trip in less time than it would take the particle to traverse an equal distance without a barrier -- in other words, the tunneling speed apparently greatly exceeds the speed of light. Moreover, if you increase the thickness of the barrier the tunneling speed increases, as high as you please..."

  • December 5, 2013, news.mit.edu: You can’t get entangled without a wormhole. MIT physicist finds the creation of entanglement simultaneously gives rise to a wormhole Citat: "...Essentially, entanglement involves two particles, each occupying multiple states at once — a condition referred to as superposition. For example, both particles may simultaneously spin clockwise and counterclockwise. But neither has a definite state until one is measured, causing the other particle to **instantly** assume a corresponding state. The resulting correlations between the particles are preserved, even if they reside on opposite ends of the universe...But what enables particles to communicate instantaneously — and seemingly faster than the speed of light — over such vast distances? Earlier this year, physicists proposed an answer in the form of “wormholes,” or gravitational tunnels. The group showed that by creating two entangled black holes, then pulling them apart, they formed a wormhole — essentially a “shortcut” through the universe — connecting the distant black holes...“There are some hard questions of quantum gravity we still don’t understand, and we’ve been banging our heads against these problems for a long time,” Sonner says. “We need to find the right inroads to understanding these questions.”...This is where quantum entanglement could play a role. It might appear that the concept of entanglement — one of the most fundamental in quantum mechanics — is in direct conflict with general relativity: Two entangled particles, “communicating” across vast distances, would have to do so at speeds faster than that of light — a violation of the laws of physics, according to Einstein...", backup

  • October 21, 1999, scientificamerican.com: What is known about tachyons, theoretical particles that travel faster than light and move backward in time? Is there scientific reason to think they really exist? Citat: "..."Briefly, tachyons are theoretically postulated particles that travel faster than light and have 'imaginary' masses...Tachyons have never been found in experiments as real particles traveling through the vacuum, but we predict theoretically that tachyon-like objects exist as faster-than-light 'quasiparticles' moving through laser-like media. (That is, they exist as particle-like excitations, similar to other quasiparticles called phonons and polaritons that are found in solids. 'Laser-like media' is a technical term referring to those media that have inverted atomic populations, the conditions prevailing inside a laser.)...[]..."We are beginning an experiment at Berkeley to detect tachyon-like quasiparticles. There are strong scientific reasons to believe that such quasiparticles really exist, because Maxwell's equations, when coupled to inverted atomic media, lead inexorably to tachyon-like solutions...", backup

  • Defense Intelligence Reference Document. Acquisition Threat Support: 2 April 2010, Warp Drive, Dark Energy, and the Manipulation of Extra Dimensions Citat: "...In recent years, however physicists have discovered two loopholes to Einstein's ultimate speed limit: the Einstein-Rosen bridge (commonly referred to as "wormhole") and the warp drive. Fundamentally, both ideas involve manipulation of spacetime itself in some exotic way that allows for faster-than-light (FTL) travel...Essentially, the wormhole involves connecting two potentially distant regions of space by a topological shortcut. Theoretically, one would would enter the wormhole and instantaneously be transported to the exit located in a distant region of space. Although no observational evidence of wormholes exists, theoretically they can exist as a valid solution to general relativity...", backup
