No, Black Holes Will Never Consume The Universe

O.o.
No matter how long you wait, the matter that makes you probably won’t end up inside a black hole.

Los Angeles Power and Water officials have struck a deal on the largest and cheapest solar + battery-storage project in the world, at prices that leave fossil fuels in the dust and may relegate nuclear power to the dustbin.
Later this month the LA Board of Water and Power Commissioners is expected to approve a 25-year contract that will serve 7 percent of the city’s electricity demand at 1.997¢/kwh for solar energy and 1.3¢ for power from batteries.
“This is the lowest solar-photovoltaic price in the United States,” said James Barner, the agency’s manager for strategic initiatives, “and it is the largest and lowest-cost solar and high-capacity battery-storage project in the U.S. and we believe in the world today. So this is, I believe, truly revolutionary in the industry.”
Blood flows into the brain primarily via the carotid arteries and the vertebral arteries. The Circle of Willis is a circular arterial structure in the brain that connects blood flowing in from the carotid arteries with blood flowing in from the basilar artery (which is fed by the vertebral arteries). Blood flows from the Circle of Willis into brain tissue via the anterior, middle, and posterior cerebral arteries. Many studies have shown that the Circle of Willis is incomplete in most people. A 1998 study of 150 healthy adult volunteers showed a complete Circle of Willis in only 42% of cases — more often complete in younger persons and females [RADIOLOGY; Krabbe-Hartkamp, MJ; 207:103–111 (1998)]. A slightly more encouraging 2002 study of 118 healthy volunteers in the 65–68 age group, showed 47% had a complete Circle of Willis [THE JOURNAL OF CARDIOVASCULAR SURGERY; Macchi, C; 43:887–890 (2002)]
For cryonics purposes, it has been believed that perfusion into the carotid arteries, but not into the vertebral arteries will result in incomplete perfusion of the brain if the Circle of Willis is not complete. In particular, if both posterior communicating arteries are missing, then perfusing only through the carotid arteries will result in no blood getting to parts of the brain supplied by the posterior cerebral arteries. Both posterior communicating arteries were missing in 11% of those in the 1998 study and in 14% of those in the 2002 study cited above.
Nonetheless, a 2008 study showing Circle of Willis complete in only 40% of 99 patients found no case of insufficient perfusion in functional tests of patients given unilateral cerebral perfusion. The authors concluded that “extracranial collateral circulation” provides an alternative pathway to the Circle of Willis for cerebral crossperfusion [EUROPEAN JOURNAL OF CARDIOTHORACIC SURGERY; Urbanski, PP; 33:402–408 (2008)]. Although persons with missing posterior communicating arteries could easily have pathways to opposite sides of the brain, other variants of Circle of Willis incompleteness would be expected to prevent perfusion across hemispheres.
Modern day female longsword expert wins the The Longsword Competition at the World Invitationals.
Trained in European martial arts as she puts it (When you think ‘martial arts’ it usually brings up images of Far East fighting styles, so this was interesting to hear European sword fighting described in this way), and using swords that she herself designed (specifically for her style of fighting and longsword competition), Samantha Swords is a girl after my own ‘Geek’ heart.

What are the key driving forces shaping the emerging future of business meetings, events, and conferences?
The next five years promise to bring fundamental changes across society – from the clients we serve, to the technology we use, and the needs and priorities of business – literally everything is “up for grabs”. At the same time, societal shifts, changing delegate and employee expectations, economic shifts, and financial uncertainty will all add to this mix – creating complexity, new opportunities, unexpected challenges, and a pressure to stay ahead of the game in spotting what’s next. Here we outline 20 developments that will become more prominent and potentially become major industry trends over the next five years.
The next five years could see more dramatic change taking place in the meetings sector than we have seen since its emergence. A powerful combination of economic, social, technological, and environmental factors will create new opportunities and challenges and force the sector to undertake a fundamental rethink of literally every aspect of what it does. Some will act fast to be ahead of the curve and use these impending changes as an opportunity to innovate in advance of the competition, others will inevitably wait until they are forced to by customers and competitive pressures. The choice over when to act is down to the individuals involved – but panic and crisis driven strategies rarely provide sustainable business advantage.
Other than technology, which areas of the economy, life, and society might have the biggest future impact on the events and meetings industry?

Is a massive, planetary-wide, space surveillance system currently being constructed that aims to monitor you all the way down to your DNA. Officially, the Space Fence is, according to Wikipedia, a 2nd generation space surveillance system being built (started in 2014) by the US Air Force and Lockheed Martin to track artificial satellites and space debris. Its budget is US$1.594 billion, it’s expected to be operational in 2019 and the Space Fence facility will be located in the Marshall Islands along with an option for another radar site in Western Australia. The Space Fence is a resurrection of a program started by Reagan in the 1980s called SDI (Strategic Defense Initiative), commonly known by its nickname “Star Wars.” However, like many exotic weapons of the New World Order, it has a cover purpose and a real purpose. This article exposes the grander implications of the Space Fence – and how it connects to other technology that could be used to enslave you.

It sounds like science fiction, but the idea of moving heavy industries off Earth seems far less far-fetched ever before.
Collecting resources from other planets or asteroids instead of using up what little we have left on Earth could be the key to ensuring that human beings survive, Discover Magazine reports.
“The solar system can support a billion times greater industry than we have on Earth,” Phil Metzger, a planetary scientist at the University of Central Florida, told Discover. “When you go to vastly larger scales of civilization, beyond the scale that a planet can support, then the types of things that civilization can do are incomprehensible to us.”
Researchers from the Monash Biomedicine Discovery Institute have made progress in the quest to rejuvenate the aging immune system by identifying the factors responsible for the age-related decline of the thymus.
The thymus shrinks as we age
The thymus is one of the most important organs in the body, and it is where thymocytes produced in the bone marrow travel to become new T cells before being trained in the lymph nodes to become the defenders of the adaptive immune system. However, as we get older, the thymus increasingly turns to fat and starts to shrink, causing its ability to produce new T cells to fall dramatically. This process is known as thymic involution and actually begins shortly after puberty, so this is one aspect of aging that begins fairly early in life, although it is many decades later before its decline causes serious health issues.
A grid full of 10 giant coaxial octocopters, each with a pilot on board, racing each other head-to-head through the air at speeds up to 200 km/h (120 mph)? That’s exactly what the Airspeeder racing series is set to introduce in 2020 with the aim of being a kind of Formula One for flying cars.
