Objects, including spacecraft, could pierce through the universe using several black holes as a ‘shortcut’, a new study suggests.
The new theory posited by French physicist Pascal Koiran marks a break from earlier research in the field of black hole studies. Previously, it was thought that a so-called ‘wormhole’ composed of two black holes would be prone to instantly collapse, thus making it impossible for an object to successfully travel all the way from one side and out the other. However, by employing different metrics, the French scientist’s new model has arrived at a very different conclusion: “We show that the particle reaches the wormhole throat for a finite value t′1 of the time marker t′.” In essence, that means an object, for instance, a spacecraft, could pass through this wormhole portal intact and reach some far-away region of the universe, taking far less time than would be needed if traveling conventionally.
The study in its entirety will see the light of day in the upcoming issue of the Journal of Modern Physics D, though an abstract has been available since early October.
Yet, there are too many ifs as to whether this purely theoretical model has any bearing on the way the universe actually works. For starters, to create such a time-and-space tunnel you would need a regular black hole and a so-called white hole, which is essentially a black hole in reverse. While black holes never let anything out, their ‘twins’ never let anything in. So, according to Albert Einstein’s theory of general relativity and Nathan Rosen’s additions to it, if you were to connect the two, they would make up a bridge across time and space. However, if the laws postulated by another branch of physics, thermodynamics, are anything to go by, such a construct would be highly unstable. Perhaps more importantly, the very existence of white holes has yet to be proven beyond a reasonable doubt. At present, they remain a pure theorization, thus putting any talk of space-and-time portals on rather shaky ground.
An adviser to the EU’s top court has claimed that citizens’ information in Germany is being illegally harvested, after telecom companies challenged bulk data collection.
The German data retention law was criticized on Thursday by an adviser to the Court of Justice of the European Union (CJEU), who stated that general and indiscriminate retention of traffic and location data is only allowed in exceptional cases, such as a threat to national security.
According to the adviser, bulk collection of data generates a ‘serious risk’ of leaks or improper access. It also entails a ‘serious interference’ with citizens’ fundamental rights to privacy and the protection of personal data.
This comes after two companies, SpaceNet and Telekom Deutschland, challenged the obligation to store their customers’ telecommunications traffic data in 2016. The Administrative Court of Cologne ruled that the two companies were not obliged to retain data because such an obligation violated Union law. Germany then appealed to the Federal Administrative Court, who asked the CJEU about the compatibility of the data retention obligation.
The CJEU has often stated that indiscriminate mass surveillance does not fit within the general principles of EU law. Over a year ago it saw a similar case involving legal challenges around national bulk data collection under UK and French law. The court then ruled that only limited data collection and temporary retention were allowed. France seeks to bypass the CJEU on data retention and has asked the country’s highest administrative court (the Council of State) not to follow the EU ruling. France is waiting for the conclusion of the procedure launched by the Council of State before “assessing to what extent” national law should be changed.
Despite recent EU court attempts to curb surveillance powers, leaked papers from June 2021 show that the national governments of the Netherlands, France, Spain, Luxembourg, Slovakia, and Estonia are pushing for a new pan-EU data retention law. They claim that data retention is essential for safeguarding public security and ensuring effective criminal investigations.

France shouldn’t remain silent on Julian Assange, leftist leader Jean-Luc Melenchon has said, after the imprisoned WikiLeaks co-founder’s father suggested that Paris could offer asylum to his son.
The life of Assange – who is being held in solitary confinement at London’s Belmarsh maximum security prison while a British court considers an extradition request by the US – is under threat, Melenchon wrote on Twitter on Tuesday.
“For years, we’ve been calling for France to accept him,” the head of the leftist La France Insoumise (France Unbowed) party said, insisting that “France shouldn’t remain silent.”
The statement by Melenchon, who won 19.6% of the ballot in the first round of the French presidential election in 2017, follows a visit by Assange’s father, John Shipton, to the Whistleblower Meeting in Paris on Monday.
During the event, Shipton told Sputnik news agency that it would be “an honorable thing” for the French government to grant his son asylum.
“I feel that France hasn’t attacked Julian over the last 12 years and consequently France is free to act in return for the information that WikiLeaks and Julian brought to France,” he said, referring to the website’s revelations of the US intelligence agencies spying on French presidents and hacking into local banks.

Several dozen French lawmakers have also recently called upon Paris to take Assange in, with the Australian-born publisher’s legal team saying last year that their client was hoping to find asylum on French soil.
Assange could face up to 175 years behind bars if he’s extradited to the US, where he’s wanted on espionage charges over the release by WikiLeaks of classified documents on Iraq, Afghanistan, Guantanamo Bay, and others.
He was placed in Belmarsh in April 2019 over breach of bail, after being holed up in the Ecuadorian Embassy in London for seven years.
The publisher had been fleeing an arrest warrant issued over sexual assault allegations which he has always denied, and which failed to result in any actual charges due to lack of evidence.
Assange’s supporters insist that he has actually been persecuted over his legitimate journalistic activities and revealing the truth to the public.
The UK High Court is expected to rule on the appeal by the US against a lower court decision to bar the WikiLeaks co-founder’s extradition to America due to the 50-year-old’s poor health condition and risk of suicide.
Assange’s team will then be able to challenge the ruling in the Supreme Court if it’s not favorable.

Brazil’s former President Luiz Inacio Lula da Silva has said he is willing to stand as a candidate in elections against incumbent leader Jair Bolsonaro, labelling his potential opponent “a poor copy of Trump.”
Speaking in Brussels at a media conference in the European Parliament on Monday, Lula announced that the Workers Party needs to put forward a presidential candidate to take over from right-wing Bolsonaro in 2022 and said he was willing to run in the elections again.
“I’m willing, I’m motivated, I’m in good health,” Lula stated, adding that said he would only make his decision early next year, some months before the election scheduled for October 2022. The popular leftist said his candidacy would depend on whether the party wanted him.
“We need to have someone who stands, we need to win the elections. And at the same time, we have to rebuild Brazil,” he said, speaking on behalf of his Workers Party.
Lula, 76, also took aim at the incumbent president. “He’s a poor copy of Trump. But Bolsonaro doesn’t think, he doesn’t have any ideas,” the former president said, claiming the incumbent leader was hellbent on ensuring the beneficial legacies of Lula’s administration were “torn down.”
A recent poll put him 27 points ahead of Bolsonaro, despite his candidacy not officially being announced.
In 2010, Lula made way for his protégé, Dilma Rousseff. Rousseff was ousted from power in what was described by her supporters as a parliamentary coup. Lula served nearly two years in prison after being convicted on money laundering and corruption, despite a nine-and-a-half-year sentence. He was also barred from running in the 2018 election.
A number of judges have subsequently ruled that the case against Lula was unlawful and the Supreme Court annulled his earlier convictions, meaning he can face off against Bolsonaro in 2022.
A stream literally flowing with booze emitting a strong beery odor has been discovered in one of the tropical islands of Hawaii. Its waters have been apparently contaminated with alcohol after a leak at a beverage warehouse.
A small river with a distinctive alcoholic smell was recently found on the island of Oahu, some 15 miles (24 kilometers) away from Honolulu, Hawaiian capital. Its waters have been flowing through the Waipio valley and even turned into a 100-foot (30 meters) waterfall on their way.
The stream caught the attention of local environmental activists, who noticed the smell in the area.
“The other day we came here you would think it was a beer pub that hadn’t opened its doors for three or four days,” activist Carroll Cox told local Hawaii News Now. She also contacted the Department of Health about the issue.
Local media took samples from the unusual stream and had them checked at a private laboratory. It tested positive for alcohol, containing 1.2% percent of the substance in its waters – nearly a quarter the content in regular beer and strong enough to cause a buzz.
Local health authorities got involved, and an investigation into the source of contamination was launched. It was learned that the stream was coming from a drain pipe that was traced back to a warehouse of Hawaii’s largest liquor distributor, Paradise Beverages. Its representatives told local media they were working with officials to eliminate a possible spill, with the booze river apparently closing its free drinks service.
Pfizer has agreed to grant a royalty-free license to sell its anti-coronavirus pill in nearly 100 developing countries around the world.
Under the agreement signed with the Medicines Patent Pool (MPP), a UN-backed public health organization, Pfizer will not receive royalties on the sales of its promising antiviral pill in 95 poorer countries, including the states of Sub-Saharan Africa. The measure allows MPP to grant sub-licenses to “qualified” generic medicine manufacturers in each country.
The countries covered by the deal comprise around 53% of the world’s population, Pfizer said. “We believe oral antiviral treatments can play a vital role in reducing the severity of Covid-19 infections, decreasing the strain on our healthcare systems and saving lives,” Pfizer CEO Albert Bourla said.
We must work to ensure that all people – regardless of where they live or their circumstances – have access to these breakthroughs.
During its phase-two/three trial, the drug PF-07321332, trademarked as Paxlovid, reduced the risk of hospitalization or death by 89% in Covid-19 patients who took it within three days of symptom onset. The drug is administered in combination with low-dose ritonavir, a medication used to treat HIV/AIDS.
The UN and the World Health Organization (WHO) have long been urging companies to make vaccines and other forms of Covid-19 treatment accessible and affordable for developing countries.

UK Home Secretary Priti Patel has acted to proscribe the Palestinian group Hamas “in its entirety,” stating that it has significant capacity to carry out terrorist acts and has facilities to train attackers.
In a tweet on Friday, Patel stated that she had banned the Palestinian group Hamas and designated it a terrorist organization, as she reiterated the British government’s commitment to “tackling extremism and terrorism wherever it occurs.”
“Hamas has significant terrorist capability, including access to extensive and sophisticated weaponry, as well as terrorist training facilities,” she wrote.
The home secretary’s tweet came during her visit to Washington and followed speculation on Friday morning that she was soon to outlaw the group.
Pre-empting Patel’s announcement, Israeli Prime Minister Naftali Bennett welcomed Britain’s “intention” on Twitter.
“Hamas is a radical Islamic group that targets innocent Israelis & seeks Israel’s destruction. I welcome the UK’s intention to declare Hamas a terrorist organization in its entirety – because that’s exactly what it is,” Bennett wrote, thanking the leadership of Prime Minister Boris Johnson.
Yair Lapid, Israel’s foreign minister, also hailed the expected move against Hamas, saying it was “part of strengthening ties with Britain.”
Until now, only Hamas’ military wing, the Izz al-Din al-Qassam Brigades, had been outlawed by the British government. The EU and the US have already proscribed all of Hamas.
Hamas political official Sami Abu Zuhri rejected Britain’s move, claiming it showed “absolute bias toward the Israeli occupation and is a submission to Israeli blackmail and dictations.”
In a separate statement, the group claimed it had a right to resist occupation by all available means, “including armed resistance.”
Hamas seized total control of Gaza in 2007, on the back of an election victory in 2006.
