Physicists Have Detected The Background Hum of The Universe
Teams in Australia, the US, Europe, China, and India are releasing their results simultaneously in a slew of papers.
"We've been on a mission for the last 15 years to find a low-pitch hum of gravitational waves resounding throughout the Universe and washing through our galaxy to warp space-time in a measurable way," astrophysicist Stephen Taylor of Vanderbilt University and chair of NANOGrav, the team in the US, said in a press briefing.
"We're very happy to announce that our hard work has paid off, and … we have exciting evidence of this background of gravitational waves."

NANOGrav's signal has a confidence level of 4 sigma across 67 pulsars, or 99.349 percent. The PPTA's signal has a lower confidence level because it studied fewer pulsars; their detection is based on just 30 stars but over a longer period. The gold standard for a discovery is 5 sigma. So there's still a lot of work to be done.
Our home galaxy, however, is now being observed for the first time in a brand new way.
Scientists said on Thursday they have produced an image of the Milky Way not based on electromagnetic radiation - light - but on ghostly subatomic particles called neutrinos. They detected high-energy neutrinos in pristine ice deep below Antarctica's surface, then traced their source back to locations in the Milky Way - the first time these particles have been observed arising from our galaxy.

A book titled “Biocentrism: How Life and Consciousness Are the Keys to Understanding the Nature of the Universe“ has stirred up the Internet, because it contained a notion that life does not end when the body dies, and it can last forever. The author of this publication, scientist Dr. Robert Lanza who was voted the 3rd most important scientist alive by the NY Times, has no doubts that this is possible.Beyond time and space
Quote:
ut not so long ago, the scientist became involved with physics, quantum mechanics and astrophysics. This explosive mixture has given birth to the new theory of biocentrism, which the professor has been preaching ever since. Biocentrism teaches that life and consciousness are fundamental to the universe. It is consciousness that creates the material universe, not the other way around.
Lanza points to the structure of the universe itself, and that the laws, forces, and constants of the universe appear to be fine-tuned for life, implying intelligence existed prior to matter.
He also claims that space and time are not objects or things, but rather tools of our animal understanding. Lanza says that we carry space and time around with us “like turtles with shells.” meaning that when the shell comes off (space and time), we still exist.
The theory implies that death of consciousness simply does not exist. It only exists as a thought because people identify themselves with their body. They believe that the body is going to perish, sooner or later, thinking their consciousness will disappear too. If the body generates consciousness, then consciousness dies when the body dies.
But if the body receives consciousness in the same way that a cable box receives satellite signals, then of course consciousness does not end at the death of the physical vehicle. In fact, consciousness exists outside of constraints of time and space. It is able to be anywhere: in the human body and outside of it. In other words, it is non-local in the same sense that quantum objects are non-local.
Lanza also believes that multiple universes can exist simultaneously. In one universe, the body can be dead. And in another it continues to exist, absorbing consciousness which migrated into this universe.
Quote:
This means that a dead person while traveling through the same tunnel ends up not in hell or in heaven, but in a similar world he or she once inhabited, but this time alive. And so on, infinitely. It’s almost like a cosmic Russian doll afterlife effect.
Multiple worlds
This hope-instilling, but extremely controversial theory by Lanza has many unwitting supporters, not just mere mortals who want to live forever, but also some well-known scientists. These are the physicists and astrophysicists who tend to agree with existence of parallel worlds and who suggest the possibility of multiple universes. Multiverse (multi-universe) is a so-called scientific concept, which they defend. They believe that no physical laws exist which would prohibit the existence of parallel worlds.The first one was a science fiction writer H.G. Wells who proclaimed in 1895 in his story “The Door in the Wall”.

That concepts like time and space only exist in our minds doesn't make sense, it's proven that time changes with gravity, for example an atomic clock runs slower in space than on earth and astronauts on the ISS age more slowly.
Or maybe we're just part of the Borg and programmed to think that.
Awesome, awesome innovation by China to help reduce environment contamination.

By incorporating certain soy proteins into the structure, Chinese University of Hong Kong scientists successfully created edible food packaging.
Quote:
Now, scientists at the Chinese University of Hong Kong have developed an edible, transparent and biodegradable material with considerable potential for use as food packaging.
The heavy reliance on petrochemicals and inherent non-biodegradability of plastic packaging means it has long been a significant contributor to environmental contamination. The team members have turned their attention to bacterial cellulose (BC) – an organic compound derived from certain types of bacteria that has gained attention as a sustainable, easily available and non-toxic solution to the pervasive use of plastics.
Quote:
In the recent paper, published in the Journal of the Science of Food and Agriculture and titled “Edible, strong, and low-hygroscopic bacterial cellulose derived from biosynthesis and physical modification for food packaging,” the researchers presented a novel approach to address the limitations of BC-based materials.
By incorporating certain soy proteins into the structure and coating it with an oil-resistant composite, the scientists successfully created an edible, transparent and robust BC-based composite packaging.
Quote:
Ngai noted that this approach has high feasibility for scale-up. “It doesn’t need specific conditions like chemical reactions, but rather a simple and practical method with mixing and coating,” he added. “This approach offers a promising solution to the challenge of developing sustainable and environmentally friendly packaging materials that can replace single-use plastics on a large scale.”
The study showed that the plastic alternative could be degraded completely within one or two months. Unlike other bio-derived plastics such as polylactic acid, the BC-based composite does not require specific industrial composting conditions to degrade. “The material developed in this research is completely edible, making it safe for turtles and other sea animals to consume without causing aquatic toxicity in the ocean,” Ngai continued.
Get skilled up or get left behind... it's a part of every career.
And when the majority of jobs start getting automated? This is only going to expand. I'm not really sure our model of capitalism can survive when people can't work to make money to buy things. UBI?

Tax the proceeds of automation and implement a UBI. If it takes effort to do a task society is better off. Making sure that surplus is distributed in a manner that supports society is what is needed.

Umm, how is that relevant when we're on track to automate most of the workforce, lol? People are so naive to what's happening.
The next step for society is not people losing their jobs to automation figuring out how to upgrade their skills, it's how governments will deal with an exponential explosion in unemployment in the coming decades. Like, c'mon, haha.

Every country will be forced into UBI. The question is how quickly a country can accept what is coming and start implementing it into their budget. It will only get more difficult and lead to more destabilization of societies the longer governments wait.

I think this transition is likely easier than we think it will be. In one of the last UBI threads it looked like if Canada increased the amount of GDP spent by government to be inline with nordic countries it could afford a Covid level UBI.
The benefit of this particular coming crisis is it is based on a surplus of available labour/energy rather than scarcity. There is enough resources for everyone to maintain standards of living as opposed to government changing crisis’s like drought or energy crisis’s where scarcity is the driver.
This is the tech thread though so not quite the right place.
Nice seeing this coming out of Chinese U. I get the sense that despite the changes and turmoil that occurred around the takeover of HK, the HK universities are going to have bright futures, especially with top academics of Chinese backgrounds who have been in the US seeing better opportunity back in China. I kind of expect to see China support HKU to stay on a level with Tsinghua, BeiDa, and Fudan, with CUHK and UST on a tier just beneath that with places like Shanghai Jiaotong.
