A pair of researchers at Applied Physics has created what they describe as the first general model for a warp drive, a model for a space craft that could travel faster than the speed of light, without actually breaking the laws of physics. Alexey Bobrick, and Gianni Martire have written a paper describing their ideas for a warp drive and have…

Hoinga: Debris of stellar explosion found in unexpected location
In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed “Hoinga.” The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our Galaxy using multiple wavelengths, from low-frequency radio waves to…
A warp drive that doesn’t break the laws of physics is possible
Previous ideas for warp drives have required types of matter that do not seem to exist, but a new concept could allow them to be made without any imaginary substances Source: https://www.newscientist.com/article/2269544-a-warp-drive-that-doesnt-break-the-laws-of-physics-is-possible/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Quantum Computer Solves Decades-Old Problem Three Million Times Faster Than a Classical Computer
ZDNet reports: Scientists from quantum computing company D-Wave have demonstrated that, using a method called quantum annealing, they could simulate some materials up to three million times faster than it would take with corresponding classical methods. Together with researchers from Google, the scientists set out to measure the speed of simulation in one of D-Wave’s quantum annealing processors, and found that…
Why does this galaxy look older than its years?
To the extent that we can see them, galaxies in the very early universe should look relatively young and unformed. But galaxy ALESS 073.1 is a surprise to astronomers: it looks more mature than we’d have any reason to expect. Why? Source: https://earthsky.org/space/galaxy-looks-older-than-its-years-aless-073-1…
Researchers discover mechanism behind influence of irradiation defects on tritium permeation barrier
Recently, researchers led by Prof. Zhou Haishan from the Institute of Plasma Physics (ASIPP) of the Hefei Institutes of Physical Science (HFIPS) reported their new findings about the influence of irradiation effects on hydrogen permeation through alpha-alumina (α-Al2O3) tritium permeation barrier (TPB). …
Researchers produce beams of entangled atoms
Heads or tails? If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects. In the world of quantum physics, things are different: Quantum particles can be entangled, in which case they can no longer be regarded as independent individual objects, they can only…
Merging boson stars could explain massive black hole collision and prove existence of dark matter
An international team of scientists led by the Galician Institute of High Energy Physics (IGFAE) and the University of Aveiro shows that the heaviest black hole collision ever observed, produced by the gravitational-wave GW190521, might actually be something even more mysterious: the merger of two boson stars. This would be the first evidence of the existence of these hypothetical objects, which…
Delayed radio flares from a tidal disruption event
A team of researchers from the Hebrew University of Jerusalem (HUJI) led by Dr. Assaf Horesh have discovered the first evidence of radio flares emitted only long after a star is destroyed by a black hole. Published in the periodical Nature Astronomy, the discovery relied upon ultra-powerful radio telescopes to study these catastrophic cosmic events in distant galaxies called Tidal Disruption…
