A potential model for a real physical warp drive

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…

SpaceX Launches 60 New Starlink Satellites

SpaceX has launched another batch of its Starlink satellites — the usual complement of 60 of the low Earth orbit spacecraft, which will join the more than 1,000 already making up the existing constellation. This is the fifth launch of Starlink satellites for SpaceX this year, and the 20th overall. From a report: Earlier this year, SpaceX opened up Starlink access…

Dropping Nearly 20%, Bitcoin Suffers Worst Weekly Drop in a Year

“Bitcoin’s rally this year has hit a speed bump, putting it on track for the worst weekly slide in almost a year amid wider losses in risk assets,” reports Fortune: The largest cryptocurrency slumped as much as 20% this week, the most since March, and was holding at about $46,925 as of 10:22 a.m. in Hong Kong. The wider Bloomberg Galaxy…

Is the Net Neutrality Debate a Pointless Distraction?

“People may scream at me for saying this, but net neutrality is one of America’s longest and now most pointless fights over technology.” So argues the New York Times “On Tech” newsletter author Shira Ovide, calling the debate “a distraction for our elected leaders and corporations when there are more pressing issues.” Ovide also shares their discussion with Times technology and…

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…

Cosmic ray originated in cataclysmic event

Astronomers found a high energy neutrino – a cosmic ray – that apparently originated during a “tidal disruption event,” that is, when a supermassive black hole shredded a distant star. Source: https://earthsky.org/space/origin-cosmic-ray-when-black-hole-shreds-star…
