(TMU) — Scientists have been trying to get a better understanding of gamma ray bursts for decades.
Now, according to astrophysicists, new observations suggest that superliminal gamma ray bursts may exceed the speed of light, though this does not actually violate Einstein’s theory of relativity. The scientists also say the light curvature of these cosmic gamma jet-streams express a bizarre characteristic known as time-reversibility.
Gamma-ray bursts (GRBs), which are the brightest electromagnetic event in the known universe, are believed to occur when a high-mass star goes supernova and rapidly collapses into a neutron star or black hole. Black-hole powered galaxies, known as blazars, are thought to be the most common source.
In their stunning new paper published in the Astrophysical Journal, astrophysicists Jon Hakkila of the College of Charleston and Robert Nemiroff of Michigan Technological University, explain how GRBs may exceed the speed of light in localized gas clouds.
They do not, however, violate Einstein’s theory of general relativity—which states that nothing can travel faster than the speed of light in a vacuum— because the gamma ray bursts are not actually traveling in a vacuum but rather the jet medium.
GRBs also feature time-reversibility, an extremely complex phenomena that similarly does not violate any known laws of physics and that can be expressed mathematically or in thermodynamics.
The paper’s authors compare GRB speed and time-reversibility to a person on one side of a pond skipping a stone toward another person on the other side of a pond: the stone will travel through the air faster than its emergent waves can travel through the water; and the waves will arrive at the person on the other side in reverse order, with the most recently created waves arriving first.
“Standard gamma-ray burst models have neglected time-reversible light curve properties,” Hakkila says. “Superluminal jet motion accounts for these properties while retaining a great many standard model features.”
Smoothie Robot In Walmart Signals Continued Rise Of Automated Fast Food Workers
A robot that makes smoothies was showcased at a Walmart in California signaling the rise of automated workers.
The Mind Unleashed has previously reported on how automated robots were beginning to take over various different jobs, including flipping burgers with Miso Robotics’ Flippy. Now, Walmart has partially got involved in the trend. A new start-up company called, “Blendid” showcased its product at the Fremont Walmart in California this week opening a kiosk, Yahoo News reported.
The stall is open seven days a week and is pitched as a way for customers to place contactless orders for a smoothie. Customers place their orders for a 12-ounce delicious drink and then an autonomous robot whips it up. What’s more, the drink is made in just 3 minutes or less from the time it’s placed.
Digital Trends recently questioned the CEO Vipin Jain about how the robot works. Jain explained that customers use an app scanning a simple QR code at the kiosk or via the Blendid app to order. If that doesn’t impress you, how about artificial intelligence that remembers your taste preferences?
“Consumers use their cell phone to order by scanning a QR code at the kiosk or via the Blendid app,” Vipin Jain, Blendid’s CEO and co-founder, told Digital Trends. “They browse our menu of smoothies made from whole fruits, and vegetables. Once they select a drink, they customize it to their personal taste and health preferences, by modifying the amount of each ingredient as desired. Then they place their order, and Blendid robot gets to work preparing their drink. Once the drink is ready, they receive a text with instructions for a contactless drink pickup. The robot serves the drink to them when they confirm the pickup.”
While a robot taking over a job like making a smoothie might seem small, the fact Walmart has an automated kiosk in one of its California stores is a larger signal of the automation trend to come.
In fact, it was previously reported by Fox News in July that, Walmart was looking to remove all cashiers and standard conveyor belt lines from its stores and is testing a pilot in one of its superstores in Fayetteville, Arkansas in the short term.
CNN previously reported that grocers – big and small chains alike – are turning to robots for performing various tasks like cleaning floors, stocking shelves, and delivering groceries to shoppers. The CV crisis could even prompt online retail warehouses like Amazon to invest more into automation technology as well.
Walmart also isn’t the first business to discuss using automation. Last year international fast-food chain McDonald’s reported they would begin employing automated fryer robots throughout their different branches across the world. Former McDonald’s USA CEO Ed Rensi told Fox Business, “It’s cheaper to buy a $35,000 robotic arm than it is to hire an employee who’s inefficient making $15 an hour bagging French fries.” McDonald’s has also introduced touchscreen ordering kiosks to some of its stores.
Restaurant chains that are using automation include McDonalds, KFC, Panera, Wendys, Dunkin’ Donuts, and Arbys according to Business Insider.
Robots aren’t just taking over restaurants, a report by the McKinsey Global Institute indicates there are 800 million careers (or 30 percent of the global job force)—from doctors to accountants, lawyers to journalists—that will be lost to automation by 2030. The report concludes that hundreds of millions of people worldwide will have to find new jobs or learn new skills.
A report by the University of Oxford suggests we will face a robot job apocalypse predicting that 47 percent of U.S. jobs are at risk of being replaced by robots and Artificial Intelligence over the next fifteen to twenty years. However, with the current ongoing pandemic workers might find they are replaced quicker. Especially, any type of work that requires physical contact with a customer.
It shouldn’t be surprising for the reader that’s exactly what a report by A3, Association For Advancing Automation, detailed earlier this year. Stating all the ways that artificial intelligence and automation is being used in different industries to combat CV. Oxford Economics also published its own report warning that accelerating technological advances in automation, engineering, energy storage, artificial intelligence, and machine learning have the potential to reshape the world in 2020 through 2030s, displacing at least 20 million workers.
With CV as a catalyst to speed up the deployment of automated machines, we can probably safely say that number will be much more severe. It seems I am not the only one to share that opinion; a recent MarketWatch article written by Johannes Moenius, a professor of global business and the director of the Institute for Spatial Economic Analysis at the University of Redlands, agrees with this author’s conclusion stating “at least 50 million jobs could be automated in just essential industries.”
In fact, the Brookings Institution said in a report last month that “any CV-related recession is likely to bring about a spike in labor-replacing automation … Automation happens in bursts, concentrated especially in bad times such as in the wake of economic shocks, when humans become relatively more expensive as firms’ revenues rapidly decline.”

Nobel Prize-Winning Physicist Says Space-Time ‘Bruises’ Are Evidence of Ancient, Pre-Big Bang Universe
One of the most respected physicists in the world recently stunned the science community by claiming there is evidence our universe formed in the aftermath of a far more ancient universe. Pointing to ‘bruises’ of Hawking radiation, which he believes are the final relics of a bygone era of reality, Sir Roger Penrose says the Big Bang was not the true beginning of this universe.
Penrose, who just won the Nobel Prize for his work proving the existence of black holes, says there are anomalous blotches, or bruises, of electromagnetic radiation on the fabric of space-time. He calls them ‘Hawking Points’ and says they are likely the final relics of energy regurgitated from black holes dating all the way back to the previous universe.
These views align with a theoretical model of the universe called “conformal cyclic cosmology,” which submits that the universe is continually expanding, contracting, and reforming itself. In this theory, the distant future of one universe becomes the Big Bang-like singularity of the next universe.
However, according to Penrose, the slate is not totally wiped clean. Black holes take an extremely long time to completely evaporate and, according to Penrose, their final output of Hawking radiation can linger on into the next universe and show up as the blotches that have been documented.
In an interview with The Telegraph, Penrose stated a summary of his theory:
“I claim that there is observation of Hawking radiation. The Big Bang was not the beginning. There was something before the Big Bang and that something is what we will have in our future. We have a universe that expands and expands, and all mass decays away, and in this crazy theory of mine, that remote future becomes the Big Bang of another aeon.”
“So our Big Bang began,” he continues, “with something which was the remote future of a previous aeon and there would have been similar black holes evaporating away, via Hawking evaporation, and they would produce these points in the sky, that I call Hawking Points.
“We are seeing them. These points are about eight times the diameter of the Moon and are slightly warmed up regions. There is pretty good evidence for at least six of these points.”
Despite his success over the years, Penrose has many critics. One of them, Ethan Siegel, vigorously critiques the entire theory of “conformal cyclic cosmology” and specifically disputes Penrose’s contention that there are bruises of Hawking radiation on our universe.
“Like many before him, [Penrose] appears to have fallen so in love with his own ideas that he no longer looks to reality to responsibly test them,” Siegel writes.
Penrose responded to the criticism by reminding people that most scientists didn’t believe in black holes at first, either. They were considered mathematical curiosities that didn’t exist in reality.
So, could Penrose be right? Is our universe just the most current iteration of an infinite cosmological cycle? Can we see the dying glow of a former universe’s final black hole radiation?
Hyper-realistic robot dolphins may soon end captivity at theme parks and aquariums for good
A life-sized robotic dolphin could help finally put an end to animal captivity in marine parks and aquariums for good by replacing real-life animals.
U.S.-based animatronics company Edge Innovations has designed a revolutionary mechanical mammal that appears nearly as playful as the real thing, and the company hopes that the robot will soon be used in aquatic theme parks and Hollywood films in place of actual living animals.
So far, the robot can nod, swim in aquariums, and interact closely with humans. Developers claim that the mechanical creature is nearly identical to the cetacean, and could even coexist with robotic versions of predators like great white sharks or even the massive reptiles that Jurassic-era seas teemed with millions of years ago.
However, the huge difference here is that despite the large price tag of $26 million, this robotic dolphin is a truly cruelty-free alternative to the capture and confinement of live animals for the sake of entertainment at amusement parks and aquatic zoos – and it will likely prove cheaper than the real thing, too.
The robot dolphin weighs in at 550 pounds and has medical-grade silicone skin, and offers a viable alternative to the once-profitable industry of capturing, breeding, and training live animals.
“It’s surprising there are 3,000 dolphins currently in captivity to generate several billion dollars just for dolphin experiences,” Edge Industry CEO and founder Walt Conti told Reuters.
“There’s obviously an appetite to love and learn about dolphins and so we want to use that appetite and offer different ways to fall in love with the dolphin.”
In recent decades, animal rights activists and casual animal lovers alike have turned their back on marine parks that are seen as subjecting dolphins and other intelligent, self-aware creatures to inhumane acts just for the sake of human amusement.
Feature films like Free Willy (1993) and the documentary Blackfish (2013) have helped educate viewers about the miserable living conditions faced by orcas and other cetaceans that have been deprived of their nature life and thrust into small enclosures at amusement parks like SeaWorld.
Increased outrage over the plight of cetaceans, or aquatic mammals, have led to countries like Canada and around 20 European countries to effectively placing a ban on whales, dolphins, and porpoises being bred, imported and exported, captured or or held in captivity for entertainment purposes.
Edge Industry hopes that with its extensive experience developing animatronics for major Hollywood features – including Free Willy, Deep Blue Sea, The Abyss, and other films – the robotic replacement can soon win over those who prefer a humane alternative to viewing creatures who naturally belong in the wild.
The company has worked closely with marine biologists to replicate the physiology of dolphins and nail their natural movements.
“Everyone wants to know if using an animatronic dolphin is different to using a real dolphin. The truth is in many ways they’re the same,” Holzberg said.
“If you want to design a show that uses real dolphins you have to capture real dolphins, train them and get them to do that show,” he continued. “With creating robots you have to do exactly the same thing. The difference is you don’t have to have breeding programs, worry about safety with human beings.”
Edge Industry has seen demand for its creations decrease as major film studios opted for computer-generated images rather than practical effects and animatronics. However, the company is now focusing on developing attractions for theme parks, and its robot dolphins will soon roll out at marine parks being built in China.
“The idea of this pilot is really to create a Sesame Street under water,” Holzberg said. “Those characters taught a generation how to feel about different kinds of aspects of humankind in ways that hadn’t been imagined before. And that’s what we dream of with this project.”
Animal rights activists have greeted this new development that could spell an end to animal captivity at marine theme parks.
“There is an end in sight to cruel ‘swim with dolphins’ programs, for which young dolphins are traumatically abducted from their ocean homes and frantic mothers, sometimes illegally,” said Katherine Sullivan of PETA.
