O,.o circa 2011 antigravity? Antimatter gravity equals antigravity: D.

(PhysOrg.com) — In 1998, scientists discovered that the Universe is expanding at an accelerating rate. Currently, the most widely accepted explanation for this observation is the presence of an unidentified dark energy, although several other possibilities have been proposed. One of these alternatives is that some kind of repulsive gravity – or antigravity – is pushing the Universe apart. As a new study shows, general relativity predicts that the gravitational interaction between matter and antimatter is mutually repulsive, and could potentially explain the observed expansion of the Universe without the need for dark energy.

Ever since antimatter was discovered in 1932, scientists have been investigating whether its gravitational behavior is attractive – like normal matter – or repulsive. Although antimatter particles have the opposite electric charge as their associated matter particles, the masses of antimatter and matter particles are exactly equal. Most importantly, the masses are always positive. For this reason, most physicists think that the gravitational behavior of antimatter should always be attractive, as it is for matter. However, the question of whether the gravitational interaction between matter and antimatter is attractive or repulsive so far has no clear answer.

The group uses tools outside of the country for this attack campaign, as well as custom malware, including custom malware – including backdoor. Hartip – that Symantec has never used. Compromised computers at the time of the attack included domain controllers and file servers, and there is evidence that files are being filtered by some compromised computers. Attackers frequently used DLL side loading in this campaign and took advantage of the patched Zerologon vulnerability in August 2020.

Symantec first addressed this campaign when suspicious DLL-side loading activity on one the customers networks triggered a warning from Cloud Analytics technology available in Symantec Endpoint Security Complete (SESC).

The campaign is spread across the world, with a large number of regions detected as the victims of the attack. The common link between all the organisations that were attacked were their links to japan or japan based organisations. In the map you can clearly see that there was a reportedly Chinese-government-linked group attacking companies within China’s borders but, like many of the companies targeted in this campaign, the target in that instance is a subsidiary of a Japanese organization.

Tech giant Microsoft says it has detected cyber-attacks aimed at vaccine researchers.

Megafloods on Mars. 😃

Swept Away

The end result — which the scientists identified using data from NASA’s Curiosity rover — is that the floods shaped the surface of Mars into 30-foot-tall ripples of rock and dust. The water itself is long gone — but the scientists speculate that the floods means the planet may have been inhabitable at the time.

Jupiter and Saturn will be aligned this December, it seems. Something not seen since the middle ages. 🙂

Jupiter and Saturn are about to line up in a way not seen since the Middle Ages, astronomers say.

When the sun sets on 21 December – the winter solstice – people looking up to the sky will see Jupiter and Saturn closer than anyone alive has ever seen them before.

A new mineral found in volcano could revolutionize batteries.

A mineral made in a Kamchatka volcano may hold the answer to cheaper batteries, find scientists.

Werner Herzog criticizes Musk and SpaceX prepares to break a rocket reusability record. What’s next for Crew Dragon? It’s Musk Reads: SpaceX Edition #221.

Back in 2013, Elon Musk released the “Hyperloop Alpha” PDF outlining his vision for a space-age styled pod that would speed 700 mph through a vacuum tube. More than seven years later, one company is actually coming close to making it a reality — and we have an exclusive interview with its co-founder and first passenger. You’ll only read it in Musk Reads+.

Elon Musk made new comments about the Tesla Semi program, Tesla’s upcoming electric semi truck, and said that the vehicle will eventually have up to 1,000 km (621 miles) of range.

This new range is going to be achieved, thanks to Tesla’s new in-house battery cells and battery pack technology.

When launching Tesla Semi in 2017, the automaker said that the production versions of Tesla Semi, which is a class 8 truck with a 80,000-lb capacity, will have 300-mile and 500-mile range options for $150,000 and $180,000, respectively.
