Astronomers Say Neutron Jet Emissions Travel at Relativistic Speeds

Astronomers Say , Neutron Jet Emissions , Travel at Relativistic Speeds.

Gizmodo reports that new research suggests that the dense remains of massive stars propel jets of gas and dust at speeds of hundreds of millions of miles per hour.

Neutron stars are the stellar remains of some of the densest objects in the universe.

.

According to new research, neutron star jets can travel up to 70,836 miles per hour, just over one-third the speed of light.

.

Relativistic effects like time dilation and length contraction are believed to occur at speeds exceeding just one-tenth the speed of light.

.

James Miller Jones, , an astrophysicist at Curtin University in Australia and co-author of the research, .

Notes that neutron stars are, "so dense that they can pull material off the surface of a nearby companion star.".

That gas spirals down onto the surface of that neutron star where it gets very, very hot and dense.

Once enough of it builds up nuclear fusion reactions start to happen on the surface, James Miller Jones, astrophysicist at Curtin University in Australia and co-author, via 'Gizmodo'.

Using the Australia Telescope Compact Array and the International Gamma-Ray Astrophysics Laboratory, researchers found that thermonuclear explosions on distant stars kickstart these high-speed jet emissions.

.

When these explosions occurred, they generated high-speed jets and bright X-rays which made it possible for researchers to measure speeds.

.

The findings suggest that the staggering speed of these emissions is close to escape speed, or the needed velocity for material to escape the neutron star's gravitational speed.

.

Gizmodo reports that the team's results will inform future models of jet formation and could help reveal some of the most extreme physics in the universe.

Scientists Question Claim That T. Rex Was as Smart as Modern Monkeys

Scientists Question Claim , That T. Rex Was as Smart, as Modern Monkeys. 'Gizmodo' reports that a team of researchers recently investigated claims that the Tyrannosaurus rex could have been as smart as monkeys. Last year, a paper was published in the journal 'Comparative Neurology,' which claimed that theropods like Tyrannosaurus rex had a “monkey-like” numbers of neurons. According to that paper, this would have made the Tyrannosaurus rex "not only giant but also long-lived and endowed with flexible cognition.”. The new paper specifically referenced the previous paper and argues that theropods probably had “significantly lower neuron counts than previously proposed.". According to the team, neuron count and brain size are “flawed” proxies for measuring an ancient species’ intelligence. We argue that it’s not good practice to predict intelligence in extinct species when neuron counts reconstructed from endocasts are all we have to go on, Kai Caspar, a biologist at Heinrich Heine University Düsseldorf and the study’s lead author, via 'Gizmodo'. The possibility that T. rex might have been as intelligent as a baboon is fascinating and terrifying, with the potential to reinvent our view of the past, Darren Naish, Paleozoologist at the University of Southampton and co-author of the paper, via 'Gizmodo'.

But our study shows how all the data we have is against this idea. They were more like smart giant crocodiles, and that’s just as fascinating, Darren Naish, Paleozoologist at the University of Southampton and co-author of the paper, via 'Gizmodo'. 'Gizmodo' reports that even if Tyrannosaurus rex wasn't as intelligent as a modern monkey, it was still a terrifying creature. . The fearsome predator also has an outsized presence in popular culture, leading theropods to attract a high degree of interest.

AT&T Confirms Data Breach Affected 73 Million Customers

AT&T Confirms Data Breach , Affected 73 Million Customers. 73 million current and former AT&T customers have had their sensitive data compromised in a hack that some outlets say dates back to 2021, Gizmodo reports. The data, which includes social security numbers, email addresses, birthdates, phone numbers and AT&T account information, . was located two weeks ago in a data set released on the dark web. It's not clear if it was AT&T's systems that were breached or if the information was stolen from one of the company's vendors. Currently, AT&T does not have evidence of unauthorized access to its systems resulting in exfiltration of the data set, AT&T, via statement. The company is communicating proactively with those impacted and will be offering credit monitoring at our expense where applicable, AT&T, via statement. As a precaution, AT&T has reset the passcodes of its current customers. . The company will be reaching out to customers whose information has been compromised. . AT&T advises those who are worried about their accounts to monitor activity and credit reports.
