Several SpaceX employees who were fired after circulating an open letter calling out CEO Elon Musk’s behaviour have filed a complaint accusing the company of violating labour laws.

The complaint, made Wednesday to the National Labor Relations Board, details the aftermath of what allegedly happened inside SpaceX after employees circulated the letter in June, which, among other things, called on executives to condemn Musk’s public behaviour on Twitter — including making light of allegations he sexually harassed a flight attendant — and hold everyone accountable for unacceptable conduct.

The letter was sent weeks after a media report surfaced that Musk paid $250,000 (roughly Rs. 2,04,27,920) to the flight attendant to quash a potential sexual harassment lawsuit against him. The billionaire has denied the allegations.

Employees in their letter urged SpaceX to uniformly enforce its policy against unacceptable behaviour and commit to a transparent process for responses to claims of misconduct. A day later, Paige Holland-Thielen and four other employees who participated in organizing the letter were fired, according to the filing, which was made by Holland-Thielen to a regional NLRB office in California. Four additional employees were fired weeks later for their involvement in the letter.

A company spokesperson did not immediately respond to a request for comment.

Musk, who is the CEO of Tesla and SpaceX and is currently running Twitter, prefers to do things his own way even if that means running afoul of rules and regulations. He’s currently in a defiant fight with Civil Rights department, a California regulator that is suing Tesla for rampant racial discrimination.

Some view Musk’s management style as autocratic and demanding, as evidenced by a recent email he sent to Twitter staff giving them until Thursday evening to decide whether they want to remain a part of the business. Musk wrote that employees “will need to be extremely hardcore” to build “a breakthrough Twitter 2.0″ and that long hours at high intensity will be needed for success.

A number of engineers also said on Twitter they were fired last week after saying something critical of Musk, either publicly on Twitter or on an internal messaging board for Twitter employees.

In a statement, Holland-Thielen said as a woman engineer at SpaceX, she experienced “deep cultural problems” and comforted colleagues who had experienced similar issues.

“It was clear that this culture was created from the top level,” she said.

Still, she said part of what she liked about the company was that any person could escalate issues to leadership and be taken seriously.

“We drafted the letter to communicate to the executive staff on their terms and show how their lack of action created tangible barriers to the long term success of the mission,” Holland-Thielen said. “We never imagined that SpaceX would fire us for trying to help the company succeed.”

The firings coincide with Musk’s $44 billion (roughly Rs. 3,37,465 crore) buyout of Twitter. Around the same time, the billionaire used a sexual term to make fun of Microsoft co-founder Bill Gates’ belly and also posted a poop emoji during an online discussion with then-Twitter CEO Parag Agrawal.

After terminating the first set of employees, SpaceX allegedly interrogated dozens of others over the next two months in private meetings, telling them they couldn’t disclose those conversations to anyone else due to attorney-client privilege, according to the complaint. Four additional employees who helped draft or share the letter were fired in July and August, the filing said, adding up to nine terminations in total.

“Management used this ‘ends justifies the means’ philosophy to turn a blind eye to the ongoing mistreatment, harassment, and abuse reported by my colleagues, much of which was directly encouraged and inspired by the words and actions of the CEO,” said Tom Moline, who was also fired from SpaceX after organizing the letter.

Jeffery Pfeffer, a professor who specializes in organizational behaviour at Stanford University’s business school, said that the allegations were hardly a surprise given Musk’s leadership style at Twitter. Musk’s success at companies like Tesla and SpaceX have created what he labeled as hubris under the false notion that it was “all about individual genius.”

“Powerful people get to break the rules. They don’t think they are bound by the same conventions as other people,” Pfeffer said, criticizing Musk’s behavior. He said it showed the arrogance of Musk, one of the world’s richest men: “Why would he think he is a mere mortal?”

A Nearby Supernova May End Dark Matter Search, Claims New Study

The pursuit of understanding dark matter, which comprises 85 percent of the universe’s mass, could take a significant leap forward with a nearby supernova. Researchers at the University of California, Berkeley, led by Associate Professor of Physics Benjamin Safdi, have theorised that the elusive particle known as the axion might be detected within moments of gamma rays being emitted from such an event. Axions, predicted to emerge during the collapse of a massive star’s core into a neutron star, could transform into gamma rays in the presence of intense magnetic fields, offering a potential breakthrough in physics.

Potential Role of Gamma-Ray Telescopes

The study was published in Physical Review Letters and revealed that the gamma rays produced from axions could confirm the particle’s mass and properties if detected. The Fermi Gamma-ray Space Telescope, currently the only gamma-ray observatory in orbit, would need to be pointed directly at the supernova, with the likelihood of this alignment estimated at only 10 percent. A detection would revolutionise dark matter research, while the absence of gamma rays would constrain the range of axion masses, rendering many existing dark matter experiments redundant.

Challenges in Catching the Event

For detection, the supernova must occur within the Milky Way or its satellite galaxies—an event averaging once every few decades. The last such occurrence, supernova 1987A, lacked sensitive enough gamma-ray equipment. Safdi emphasised the need for preparedness, proposing a constellation of satellites, named GALAXIS, to ensure 24/7 sky coverage.

Axion’s Theoretical Importance

The axion, supported by theories like quantum chromodynamics (QCD) and string theory, bridges gaps in physics, potentially linking gravity with quantum mechanics. Unlike neutrinos, axions could convert into photons in strong magnetic fields, providing unique signals. Laboratory experiments like ABRACADABRA and ALPHA are also probing for axions, but their sensitivity is limited compared to the scenario of a nearby supernova. Safdi expressed urgency, noting that missing such an event could delay axion detection by decades, underscoring the high stakes of this astrophysical endeavour.

Fastest-Moving Stars in the Galaxy May be Piloted by Aliens, New Study Suggests

Intelligent extraterrestrial civilisations might be utilising stars as massive interstellar vehicles to explore the galaxy, according to a theory proposed by Clement Vidal, a philosopher at Vrije Universiteit Brussel in Belgium. His research suggests that alien species could potentially accelerate their binary star systems to traverse vast cosmic distances. While such a concept is purely hypothetical and unproven, Vidal’s recent paper, which has not undergone peer review, raises intriguing possibilities about advanced extraterrestrial engineering.

Concept of Moving Star Systems

The study was published in the Journal of the British Interplanetary Society. As per a report by LiveScience, the idea revolves around the notion that alien civilisations, instead of building spacecraft for interstellar travel, might manipulate entire star systems to travel across the galaxy. Vidal highlights binary star systems, particularly those involving neutron stars and smaller companion stars, as ideal candidates. Neutron stars, due to their immense gravitational energy, could serve as anchors for devices designed to propel the system by selectively ejecting stellar material.

Vidal explained in the paper that uneven heating or manipulation of magnetic fields on a star’s surface could cause it to eject material in one direction. This process would create a reactionary thrust, propelling the binary system in the opposite direction. The concept provides a way to travel while preserving planetary ecosystems, making it a theoretically viable method for species reliant on their home systems.

Known Examples with High Velocities

Astronomers have identified hypervelocity stars, such as the pulsars PSR J0610-2100 and PSR J2043+1711, which exhibit high accelerations. While their movements are believed to be natural phenomena, Vidal suggests they could be worth further investigation to rule out potential artificial influences.

This theory adds an unconventional angle to the search for intelligent life, expanding possibilities beyond traditional methods of exploration like searching for signals or probes. The research underscores the importance of considering advanced and unconventional methods aliens might employ to navigate the galaxy.

Hubble Telescope Finds Unexpectedly Hot Accretion Disk in FU Orionis

NASA’s Hubble Space Telescope has provided new insights into the young star FU Orionis, located in the constellation Orion. Observations have uncovered extreme temperatures in the inner region of its accretion disk, challenging current models of stellar accretion. Using Hubble’s Cosmic Origins Spectrograph and Space Telescope Imaging Spectrograph, astronomers captured far-ultraviolet and near-ultraviolet spectra, revealing the disk’s inner edge to be unexpectedly hot, with temperatures reaching 16,000 kelvins—almost three times the Sun’s surface temperature.

A Star’s Bright Outburst Explained

First observed in 1936, FU Orionis became a hundred times brighter in months and has remained a unique object of study. Unlike typical T Tauri stars, its accretion disk touches the stellar surface due to instabilities. These are caused by the disk’s large mass, interactions with companion stars, or material falling inwards. Lynne Hillenbrand, a co-author from Caltech, in a statement said that the ultraviolet brightness seen exceeded predictions, revealing a highly dynamic interface between the star and its disk.

Implications for Planet Formation

As per a report by NASA, the study holds significant implications for planetary systems forming around such stars. The report further quoted Adolfo Carvalho, lead author of the study, saying that while distant planets in the disk may experience altered chemical compositions due to outbursts, planets forming close to the star could face disruption or destruction. This revised model provides critical insights into the survival of rocky planets in young star systems, he further added.

Future Investigations on FU Orionis

The research team continues to examine spectral emission lines in the collected data, aiming to map gas movement in the star’s inner regions. Hillenbrand noted that FU Orionis offers a unique opportunity to study the mechanisms at play in eruptive young stars. These findings, published in The Astrophysical Journal Letters, showcase the ongoing value of Hubble’s ultraviolet capabilities in advancing stellar science.
