‘Groundbreaking Result’ Coming from Black-Hole Hunting Event Horizon Telescope Next Week

https://www.space.com/event-horizon-telescope-black-hole-announcement-coming-soon.html

We may be about to get an epic and unprecedented look at a black hole.

The Event Horizon Telescope (EHT) project, an international effort that aims to capture the first-ever image of a black hole, will announce a “groundbreaking result” at a news conference next week, team members said Monday (April 1).

The briefing, which will be hosted jointly by the EHT project and the U.S. National Science Foundation (NSF), takes place next Wednesday (April 10) at 9 a.m. EDT (1300 GMT) at The National Press Club in Washington, D.C. (NSF helps fund the EHT.) And you can watch the big news unfold: The event will be streamed live.

NSF Director France Córdova will speak at the news conference, as will the following panelists, according to an NSF media advisory:

  • Sheperd Doeleman, EHT director, Harvard University senior research fellow, Center for Astrophysics at Harvard and Smithsonian.
  • Daniel Marrone, University of Arizona Department of Astronomy and the Steward Observatory.
  • Avery Broderick, University of Waterloo Department of Physics and Astronomy, Perimeter Institute for Theoretical Physics.
  • Sera Markoff, University of Amsterdam, Anton Pannekoek Institute for Astronomy, Gravitation and AstroParticle Physics Amsterdam.

Related press conferences will also occur simultaneously in Brussels; Santiago, Chile; Shanghai; Taipei, Taiwan; and Tokyo, according to the NSF advisory. The speakers at these various events include some heavy hitters, such as Carlos Moedas, the European commissioner for research, science and innovation; James Liao, president of the Academia Sinica; European Southern Observatory Director General Xavier Barcons; and Atacama Large Millimeter/submillimeter Array Director Sean Dougherty.

The advisory doesn’t state what the April 10 announcement will be, but the above information suggests it’s a pretty big deal. 

If you want to try to connect some dots, here’s some basic information about the EHT. The project links up radio dishes around the globe, creating a virtual telescope about the size of Earth. The goal is to generate enough magnifying power to image the area around a black hole, especially its event horizon — the point beyond which nothing, not even light, can escape. (Directly imaging the black hole itself — the part inside the event horizon — from our perspective is, of course, impossible; there are no photons from that exotic realm to catch.)

“This capability would open a new window on the study of general relativity in the strong field regime, accretion and outflow processes at the edge of a black hole, the existence of event horizons, and fundamental black-hole physics,” the EHT team wrote in a project description.

“Over the coming years, the international EHT team will mount observing campaigns of increasing resolving power and sensitivity, aiming to bring black holes into focus,” the team added.

The EHT project focuses on the two supermassive black holes that have the largest apparent event horizons, as seen from Earth: the one at the heart of our own Milky Way galaxy, known as Sagittarius A*, and the monster that anchors the giant elliptical galaxy M87.

A Rocket Powered Golf Club That Swings At 150MPH

https://geekologie.com/2019/04/a-rocket-powered-golf-club-that-swings-a.php


This is a video of former NASA engineer Mark Rober and Smarter Every Day’s Destin Sandlin adding two F size model rocket engines to a golf club to get it swinging at 150MPH. For reference, pro golfers swing at around 110MPH, so, just like Biff’s hoverboard in Back To The Future II, this thing’s got power. Now not to brag or anything, but I bet my golf swing could probably even top that. "Have you ever even swung a golf club, GW?" Only as a weapon.
Keep going for the video, which is all fails and fine-tuning until around 10:00, when the real fun begins (which thankfully does include Mark actually taking a swing with the rocket club).

Thanks to hairless and Philip F, who are surprised Rodney Dangerfield’s character didn’t have one of these in Caddyshack (although Jack Mason’s character in Caddyshack 2 does have a 12 gauge driver).

Cloudflare’s privacy-focused DNS app adds a free VPN

https://www.engadget.com/2019/04/01/cloudflares-privacy-focused-dns-app-adds-a-free-vpn/

Cloudfare’s 1.1.1.1 DNS service will add a VPN to its app for mobile devices. Known as Warp, the feature will gives users of the DNS resolver even more privacy while browsing the internet on their phone. Though the 1.1.1.1 DNS service already keeps your carrier from tracking your browser history, it doesn’t encrypt your internet traffic. Setting up encryption manually on Cloudfare’s DNS server, while possible, required some Linux prowess.

Warp takes the next step by encrypting your connection to CloudFlare’s servers and aims to reduce data use by caching and compressing content where possible. Using it as a VPN also masks all internet traffic on your phone, including the rest of your apps.

Warp

With Warp, Cloudflare promises to keep all the privacy protections that were in place with 1.1.1.1. The company promises never to sell your browsing data, use targeted advertising or ask for any personally identifiable information such as your name or email address in order to sign-up.

The VPN will operate on a freemium model, allowing customers to upgrade to Warp+ for faster performance with a "low monthly fee." While Warp isn’t available to all 1.1.1.1. users yet, you can place your name on a waitlist in the app.

Strong Tesla sales push Norway to 58% zero-emission share in March

https://arstechnica.com/?p=1484525

Tesla Model 3

Jonathan Gitlin

Over 58 percent of passenger cars sold in Norway in March were zero-emission vehicles, according to Norway’s Road Traffic Information Office (OFV). That’s a new record for the small Scandinavian country that has long led the world in adoption of zero-emission vehicles.

The strong sales reflected pent-up demand for Tesla’s new Model 3, which only became available in large volumes in late February. The Model 3 accounted for 5,315 of the 18,375 vehicles sold in Norway in March, with the Model S and Model X selling another 500 vehicles combined.

“In 2018, Norway’s fully electric car sales rose to a record 31.2 percent market share from 20.8 percent in 2017, far ahead of any other nation,” Reuters reports.

If you include plug-in hybrid vehicles, Norway’s electric vehicle share reached around 50 percent in 2018. The comparable figure for the United States was around 2 percent.

Norway’s stunning sales of electric vehicles overall reflect aggressive policies by the Norwegian government to promote the shift away from vehicles with internal combustion engines that contribute to climate change. Norway imposes hefty taxes on conventional cars, but the country fully exempts electric (and hydrogen-powered) vehicles. As a result, electric vehicles are comparatively more affordable in Norway than they are in most other countries around the world.

Governments in Norway have made other efforts to promote electric vehicles, too.

“Capital city Oslo has made extraordinary efforts to promote EVs, including toll-free roads, HOV-lane access, free parking, and free charging,” CityLab reported in December.

According to Reuters, demand for electric cars is so strong in Norway that automakers have struggled to keep up. Tesla’s entry into the market represents a significant expansion of the availability of all-electric vehicles in the country.

March’s electric vehicle sales may prove to be a bit of an aberration driven by pent-up demand for the Model 3. But the head of the Norwegian Electric Vehicle Association, Christina Bu, told Reuters she expected electric cars to reach 50 percent of the new car market for 2019 as a whole.

A big question is what will happen if Norwegian authorities start to scale back some of the generous incentives offered for drivers of fully electric vehicles. For example, CityLab reports that electric cars’ exemption from the Value Added Tax could be phased out in 2020. Electric cars are also slated also lose their exemptions to some tolls this year. That could hamper Norway’s progress toward its goal of having all new vehicles be emissions-free by 2025.
