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.
At least ten people have been killed and several wounded by security forces during mass demonstrations in Sudan against the recent military coup, a medics organization has said.
“The coup forces used live bullets heavily in different areas of the capital and there are tens of gunshot injuries, some of them in serious condition,” the Central Committee of Sudanese Doctors (CCSD) said in a statement.
The group of medics, which supports the protest movement, said several of the injured were in critical condition. It reported ten deaths across Bahri, Omdurman and the capital Khartoum.
According to AFP, citing witnesses, security forces also fired tear gas at protesters in the capital.
Although internet services have been disrupted and telephone lines cut since the military coup on October 25, thousands of people made it to the streets of major cities.
The Sudanese Professionals Association, which also supports the demonstrators, said people were witnessing “excessive repression” and that there was a “deliberate interruption of voice and internet communications services.”
Videos posted on social media show protesters wrapping up in national flags, chanting anti-military mottos and demanding the release of activists detained by the military since the takeover. Resistance committees across Sudan adopted the Liverpool Football Club’s chant ‘You Will Never Walk Alone’ as their slogan, which has already become a popular hashtag on Twitter.
“The street is calling Thwra (revolution), The revolution says Madaniya (civilian gov)”
On October 25, following a long period of tensions between Sudan’s military and civilian-led government, General Abdel Fattah al-Burhan announced the dissolution of both the Sovereign Council and the transitional government, declaring a state of emergency. The apparent military coup immediately prompted mass protests across the country.

The EU must quickly seal its external borders to stem the flow of migrants who are no longer welcome in the 27-member bloc, according to Slovenia’s interior minister, whose country currently holds the presidency of the EU Council.
Speaking at the ‘Sarajevo Migration Dialogue’ on Thursday, Interior Minister Ales Hojs said EU countries were preoccupied recently with the coronavirus pandemic, the fall of the government in Afghanistan, and now a migrant crisis on the Poland-Belarus border, which he said was a hybrid war waged by Minsk against the EU.
“All three have additionally contributed to the increase in numbers of illegal migrants moving towards Europe and the Balkans, destabilizing the European Union,” Hojs told reporters.
The Slovenian minister said the current situation was similar to the 2015 influx of refugees and migrants from the Middle East and North Africa, when the EU admitted over one million people across its borders.
This time the situation is different, Hojs said, warning that “there is no more ‘refugees welcome.’”
“I believe that external borders must be secured, even with fences if necessary,” Hojs said, saying that he supported a plan for Brussels to finance the building of fences to reinforce the bloc’s borders.
He said it was important to strengthen cooperation and partnership across the EU in order to better manage migration and maintain security.
Thousands of migrants have been trying to cross the Belarus-Poland border in an attempt to reach the EU. They have been stranded at barbed-wire fencing with Polish border guards repelling their attempts to cross. Warsaw has accused Belarus of orchestrating the crisis to destabilize the EU and “weaponize” migration in an effort to have sanctions lifted.
A spokesperson for Belarusian leader Alexander Lukashenko claimed on Thursday that Germany agreed to open a humanitarian corridor for 2,000 refugees on the border.

French President Emmanuel Macron has dismissed the possibility of locking down unvaccinated people in France, claiming the move would not be necessary because of the success of the Covid-19 ‘health pass’.
Speaking to La Voix du Nord newspaper in an interview published on Thursday, Macron said there was no need for France to follow Austria’s lead by locking down its unvaccinated citizens.
“Those countries locking down the non-vaccinated are those which have not put in place the [health] pass. Therefore, this step is not necessary in France,” Macron claimed.
The president’s health pass, which was the target of much criticism when it was introduced, requires people to provide proof of vaccination or a recent negative test before undertaking certain normal activities.
The ‘Pass Sanitaire’ is required if citizens wish to go to restaurants, cafes, cultural venues, or cinemas. It’s also required to take long-distance trains, among other activities.
Austria has led the way by starting a partial lockdown of the unvaccinated amid a surge in Covid-19 cases. The Czech Republic will follow suit next week, while Germany decided on Thursday to introduce similar measures in areas where Covid incident rates exceed the threshold.
Earlier in November, Macron made the continued use of the Covid health pass for over 65s dependent on getting a booster jab.
Some 20,366 new infections were registered in the last 24-hour recording period. Case numbers have risen steeply in recent weeks.
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.

Ce serait honorable pour la #France d’offrir [l’asile] à Julian #Assange» pic.twitter.com/ceZ7qTARua
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.

Apple has finally caved to users demanding the ‘right to repair’, allowing owners of iPhones, MacBooks, and other devices to tinker with their electronics at home instead of bringing them to notoriously expensive service centers.
Called Self Service Repair, the feature is set to launch “early next year” in the US before expanding to other countries. Some 200 parts are expected to be available, along with instructions on how to replace them.
Initially, the company will offer repairs for the iPhone 12 and 13, to be followed by Macs with M1 chips. Users will be able to replace the phones’ display, battery, and camera – some of the earliest parts to cease functioning – using original equipment from the company. While Apple encourages only “individual technicians with the knowledge and experience to repair electronic devices,” urging users to take their devices to a professional before cracking them open themselves, the move nevertheless represents a major step for a company that has long been resistant to allowing users to even swap out a battery.
After rolling out repair instructions and parts for the iPhone 12 and 13, the company will gradually expand users’ abilities to fix their phones themselves without having to wait in line at the Apple Store. Users who attempt to make these repairs on their own will not void their warranty, according to TechCrunch, representing another major change for the tech giant.
Even this week, Apple was sealing off users’ ability to fix their own phones, barring users who replaced their own screens from being able to use Face ID recognition going forward. However, the various departments seem to be coordinating among themselves – users will receive a recycling credit for returning their used or broken part after completing the repair, and the company plans to sell “more than 200 individual parts and tools,” as well as repair manuals customers can peruse before attempting to repair their devices.
The decision to open up Apple’s “right to repair” might not have been entirely that of the company – the Federal Trade Commission wrote to the corporation earlier this year vowing to “address unlawful repair restrictions,” adding it would also “stand ready to work with legislators, either at the state or federal level, in order to ensure that consumers have choices when they need to repair products that they purchase and own.”
The International Criminal Court has halted an investigation into alleged rights abuses carried out by Philippines authorities as part of a harsh crackdown on the drug trade, saying it is reviewing a deferral request from Manila.
The ICC’s chief prosecutor Karim Khan said the probe was suspended after the Philippines government filed a request to defer the case earlier this month, according to court documents cited by Reuters on Friday.
“The prosecution has temporarily suspended its investigative activities while it assesses the scope and effect of the deferral request,” he wrote, adding that the court is seeking more information from the government in Manila.
Based in The Hague, the ICC allows states to ask for postponements if they conduct their own investigations into the charges in question. President Rodrigo Duterte’s administration filed its deferral request on November 10, while the country’s Justice Ministry announced its own investigation into the alleged abuses late last month.
The court initially opened the probe in September over allegations that Philippines police had carried out thousands of extrajudicial executions and used other brutal tactics against suspected drug dealers, and that Duterte gave implicit backing to those actions. Activists have accused authorities of killing innocent people, including children, though the police insist they only use violence in self-defense.
While Duterte has declined to cooperate with the ICC probe, saying it has no authority on the island nation, and even pulled the Philippines out of the international body in 2019, the court has jurisdiction to investigate alleged violations committed by the country while it was still a member.
The president’s chief legal counsel, Salvador Panelo, confirmed the deferral request in brief comments to Reuters, saying “There is no inconsistency with the request for suspension of action,” though he did not elaborate.
Since its founding some 20 years ago, the ICC has successfully convicted just five people of war crimes or crimes against humanity – all leaders of armed movements in Africa, including in Mali, Uganda and the Democratic Republic of the Congo.

Rotterdam Mayor Ahmed Aboutaleb has described an anti-lockdown protest in his city as an “orgy of violence.” The Dutch demonstration devolved into a violent riot that saw police open fire on protesters.
Aboutaleb described the events of Friday night as an “orgy of violence,” after protesters packed Rotterdam’s central Coolsingel shopping street to voice their opposition to an ongoing partial lockdown, a ban on New Year’s Eve fireworks displays, and the possibility of a two-tiered system of freedom in the Netherlands, one of liberty for the vaccinated and restrictions for those without the jab.
The protest soon got out of hand, and police said on Saturday that 57 people were arrested. Protesters were seen torching police vehicles and launching fireworks at police, who shot at them in response.
Aboutaleb said that the cops had been “forced” to use their weapons. “On a number of occasions the police felt it necessary to draw their weapons to defend themselves,” he told reporters. “They shot at protesters, people were injured.”
Police say at least seven people were injured. Two of these injuries were caused by police bullets, and the victims are still in hospital. One officer was hospitalized, while several others were treated at the scene for minor injuries.
