physicsDensest Object on Earth Made From Compressed Copper

Lawrence Livermore’s National Lab’s National Ignition Facility compressed microscopic copper samples with pressures of 30 million atmospheres to triple the density of copper. This created the densest object on the planet for a brief moment in time. They used diamond …

algorithmsParticle Accelerator on a Chip Will Reach a Million Electron Volts by End of 2020

Scientists at Stanford and SLAC have created a silicon chip that can accelerate electrons using an infrared laser to deliver, in less than a hair’s width, the sort of energy boost that takes microwaves many feet. Above – This image, …

controversialTime Travel Could Be Enabled by Circulating Lasers

Weak and strong gravitational fields can be produced by a single continuously circulating unidirectional beam of light. In the weak gravitational field of a unidirectional ring laser, it is predicted that a spinning neutral particle, when placed in the ring, …

physicsChip-to-chip Quantum Teleportation and Multi-photon Entanglement in silicon

Silicon is a compelling platform for classical optical telecommunications as well as quantum communications, both through optical fibers. In general, the silicon-based integrated quantum transceivers could provide possible low-cost and high-performance secure communication networks. A reliable transfer of single photon …

canadaGeneral Fusion Has Over US$100 Million to Make a Fusion Demo Plant

General Fusion has successfully closed USD$65 million with a Series E round led by Temasek (Singapore fund). There was US$38 million (C$50 million) released from the Canada’s Strategic Innovation Fund. The total funds recently made available to General Fusion is …

physicsQuantum Simulations That Are Ten Thousand Times Faster

Researchers at the University of Warwick and University of Oxford have developed a new way to simulate quantum systems of many particles, that allows for the investigation of the dynamic properties of quantum systems fully coupled to slowly moving ions. …

futureQuantum Computers and Applications Over the Next 5 Years

This article has information from the quantum computer expert John Preskill. We are going to get more and better quality qubits with lower error rates. The overhead cost for error correction improves as gate error rate declines. The Google Quantum …

energyX-ray Lasers and Electron Beam Nuclear Fusion

HZDR (German) scientists are investigating whether controlled fusion could be facilitated with the assistance of tunneling processes using radiation But that is also a question of energy: the lower it is, the lesser the likelihood of tunneling. Conventional laser radiation …

energyCommonwealth Fusion Systems Raised Another $115 Million to Reach ARC Fusion Commercialization Phase Starting 2025

Commonwealth Fusion Systems (CFS), a startup commercializing fusion energy, has raised $115 million and closed its Series A round. New participants in the round include Future Ventures, Khosla Ventures, Lowercase Capital, Moore Strategic Ventures, Safar Partners, Schooner Capital, and Starlight …

futureMach Effect Propulsion Study Proved There Is No Vibration Error

The Mach Effect Propulsion NASA NIAC study went through a lot of effort to prove there was no vibration generated errors. The entire presentation and most of the Q&A was a defense of the validity of the first test device. …
