Physicists from TU Darmstadt propose a new approach to define and measure the time required for quantum tunneling. They suggest using Ramsey clocks, which utilize the oscillation of atoms to determine the elapsed time. The proposed method may correct previous experiments that observed particles moving faster than light during tunneling.
Researcher Dr. Erik Lentz discovered a new class of hyper-fast 'solitons' that can enable travel at any speed without requiring exotic matter with negative energy density. The equations used in this research would allow space travel to Proxima Centauri and back within years, compared to current rocket technology's 50,000-year journey.
Scientists at Tata Institute of Fundamental Research and Rutherford Appleton Laboratory discovered that electrons traveling faster than light in glass live much longer than expected, lasting over 2000 times longer than the exciting laser pulse.
Sergei Kopeikin's research suggests the Pioneer anomaly can be explained by the effect of the universe's expansion on photons. This discovery could improve measurements for interstellar exploration.
Researchers at NIST have developed a novel method for generating superluminal light pulses through four-wave mixing, which can be used to improve communication timing and investigate quantum correlations. The technique introduces cleaner, less noisy pulses with increased speed, potentially enabling faster-than-light information transfer.
Delegates explored ways to overcome propulsion limitations, including suspended animation and negative mass concepts. Theoretical models offer tantalizing options, but significant hurdles remain before interstellar travel becomes a reality.
The American Institute of Aeronautics and Astronautics has published a new book on emerging science of novel propulsion concepts like space drives and warp drives. Researchers Marc Millis and Eric Davis cover NASA's Breakthrough Propulsion Physics Project, enabling human voyages to other star systems.
Physicist Robert Boyd has successfully demonstrated negative-speed pulses of light, where a pulse travels backwards within an optical fiber. The researchers used erbium-doped fibers to slow down and speed up the light pulse, creating a 'hump' shape with leading and trailing edges.
