The DragonFire laser-directed energy weapon (LDEW) system has achieved the UK’s first high-power firing of a laser weapon against aerial targets during a trial at the MOD’s Hebrides Range.

The DragonFire is a line-of-sight weapon and can engage with any visible target, and its range is classified. The system is able to deliver a high-power laser over long ranges and requires precision equivalent to hitting a £1 coin from a kilometer away.

Laser-directed energy weapons are incredibly powerful and can engage targets at lightning-fast speeds. They use a concentrated beam of light to cut through their target, resulting in structural failure or other devastating outcomes if the warhead is targeted.

The novel tech should allow scientists and filmmakers to produce videos that accurately represent the colors seen by animals such as bees for the first time.

The presence of supermassive black holes in the earliest epochs of the universe has scientists stumped — but repeated explosions from tiny black holes may offer an explanation.

What a trippy gravitational phenomenon can tell us about the universe.

Classical and Quantum Gravity Published by IOP Publishing Indexed in the Web of Science Core Collection Engages in Transparent Peer Review.

Jonathan Oppenheim at University College London has developed a new theoretical framework that aims to unify quantum mechanics and classical gravity – without the need for a theory of quantum gravity. Oppenheim’s approach allows gravity to remain classical, while coupling it to the quantum world by a stochastic (random) mechanism.

For decades, theoretical physicists have struggled to reconcile Einstein’s general theory of relativity – which describes gravity — with quantum theory, which describes just about everything else in physics. A fundamental problem is that quantum theory assumes that space–time is fixed, whereas general relativity says that space–time changes dynamically in response to the presence of massive objects.

In 1948, Schwinger developed a local Lorentz-covariant formulation of relativistic quantum electrodynamics in space-time which is fundamentally inconsistent with any delocalized interpretation of quantum mechanics. An interpretation compatible with Schwinger’s theory is presented, which reproduces all of the standard empirical predictions of conventional delocalized quantum theory in configuration space. This is an explicit, unambiguous, and Lorentz-covariant “local hidden variable theory” in space-time, whose existence proves definitively that such theories are possible. This does not conflict with Bell’s theorem because it is a local many-worlds theory.

Year 2021 face_with_colon_three Basically this is a quantum computer that time travel within the computer so it can do processing faster.

Formed inside superfluid helium-3, the time crystals were observed for a record time of over 15 minutes.
