Scientist warns a bad solar storm could spark an ‘internet apocalypse’

Can you imagine a world without the internet? As you read this article, undoubtedly through the internet, the sun is showering the Earth with magnetised particles known as the solar wind. For the most part, we’re protected by Earth’s magnetic shield which blocks solar wind from doing any real damage to our planet or its inhabitants. However, every century or so, that solar wind escalates into a solar storm—which new research suggests could be catastrophic to our global internet infrastructure (and modern inter-connected life as we know it).

The underwater cables that connect nations could go offline for months

The study, presented at the ACM SIGCOMM 2021 data communication conference, postulates that a severe solar storm could cause significant damage to underwater cables—leaving large swathes of society offline for weeks or even months. The paper, written by Sangeetha Abdu Jyothi from the University of California, Irvine, has led some to suggest that an ‘internet apocalypse’ could be imminent. Although take this with a pinch of salt as the study has yet to appear in a peer-reviewed journal.

In an interview with WIRED, Abdu Jyothi warned that she saw how “unprepared the world was” for this to happen. “There was no protocol to deal with it effectively, and it’s the same with internet resilience. Our infrastructure is not prepared for a large-scale solar event.”

The reason for this lack of preparedness stems from the fact solar storms are relatively rare. According to Abdy Jyothi’s paper, scientists estimate the probability of extreme space weather directly impacting Earth is somewhere between 1.6 and 12 per cent each decade. In fact, taking a look back in recent history, only two solar storms—one in 1859 and one in 1921—have been recorded. The former, known as the Carrington Event, was powerful enough that telephone wires burst into flames and Aurora Borealis (The Northern Lights) were spotted in the not-so-Northern country of Columbia. But these geomagnetic disturbances occurred before electric grids were established.

And after three decades of recorded low solar storm activity, researchers are suggesting there is a rising possibility that another solar storm is on our horizon. So, is it time to start panicking? You’d be forgiven for thinking so. History has shown us that even smaller storms can cause disruption. In March 1989, a storm blacked out the entire Canadian province of Quebec for nine hours—but that too occurred before modern internet infrastructure.

It goes without saying that, since then, humanity has vastly evolved: we’ve become reliant on the global internet for pretty much everything you can think of, from supply chains to online banking. Despite this, the potential impacts of a geomagnetic storm on new internet infrastructure remains largely unstudied, as Abdy Jyothi highlights in her paper.

The good news (and the bad)

The good news is that the infrastructure of what makes up the global internet is built for resilience. In the event of a solar storm, if one pathway isn’t available the traffic reroutes to different paths across the network—a system that could theoretically keep connectivity up and running. Think of these as connections as roads in a city: Abdy Jyothi warns that if enough of these connections (or roads) are damaged, then it would start to destabilise the entire network.

But it gets worse: if humanity was incredibly unlucky, cable outages could occur in a way that would malfunction foundational data routing systems, creating knock-on outages, Abdy Jyothi warns. Think of this as the internet version of a traffic jam if every road sign and traffic light stopped working on busy intersections across a major city.

Fortunately, if the worst does occur, chances are it won’t impact everyone on Earth unilaterally. Coronal mass ejections—the significant release of plasma and accompanying magnetic fields released from solar storms—tend to have more impact at higher latitudes. Bad news if you’re reading this from Northern Europe.

Abdu Jyothi worries about the cables in some regions more than others: those closer to the equator could still continue to share dank memes, but at what cost? Global geopolitical instability? Those in Asia face the least risk of solar storms, partly due to the continent’s latitude and partly due to Singapore acting as a hub for many undersea cables in the region. Underwater cables which cross the Atlantic and Pacific oceans, however, would be a greater risk from even moderate storms.

The impact extreme solar storms can have on our infrastructure is still vastly unknown. This is particularly true for the internet: history is unable to tell us the scale of damage coronal mass ejections will have on the backbone of internet infrastructure because it simply hasn’t been around long enough. Abdu Jyothi emphasises that her study is only scratching the surface and that extensive interdisciplinary research is needed to understand the scale of the threat that is at hand. However, while severe solar storms are extremely rare, it doesn’t take a rocket scientist to deduce that the stakes could be perilously high.

Scientists launch project to look for extraterrestrial visitors in our Solar System

Some of you might remember the oddly shaped object that came whizzing past the Sun and Earth in 2017 on a trajectory from outside our Solar System. Most scientists thought the cigar-shaped visitor named ‘Oumuamua, Hawaiian for ‘scout’, was a comet or asteroid from a nearby star or some other cosmic debris. But theoretical astrophysicist Avi Loeb of Harvard University argued that ‘Oumuamua was an alien creation—a light sail, antenna, or even a spaceship. On Tuesday 26 July 2021, he announced a plan to look for more such objects: a philanthropy-backed effort called The Galileo Project.

With the help of existing and new telescopes, the project will systematically look for mysterious artefacts that could be satellites hiding in Earth orbit, interstellar objects—whether natural or manufactured—and even unexplained craft in Earth’s atmosphere. “It doesn’t really matter if it’s a natural artifact or a relic. If we look, we will find something new,” Loeb said.

Artifacts that have potentially been left behind by Extraterrestrial Technological Civilisations (ETCs) could help provide clues about advanced civilisations based on the technology that they have developed, otherwise known as technosignatures. “The goal of The Galileo Project is to bring the search for extraterrestrial technological signatures from accidental or anecdotal observations and legends to the mainstream of transparent, validated, and systematic scientific research,” explained the researchers in a previous statement published 26 July.

But how did The Galileo Project come about, you ask? After Loeb published a book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, which made the case that ‘Oumuamua was some sort of alien technology, he told Science Magazine that several wealthy individuals got in touch—unsolicited—to offer funding for such research.

Four of them ended up donating $1.75 million, enough for the theoretical astrophysicist to move forward with his plans. He assembled a research team involving several well-known astronomers and researchers from other fields, although he also admitted that not everyone he approached was receptive. “The science community should be open minded. That’s how we make progress,” Loeb said.

Unlike what happened when ‘Oumuamua first showed its head, giving researchers only two months before it passed out of range of telescopes, detecting incoming objects early will give them more time to study them. Loeb also hopes to design—in collaboration with space agencies or companies—a launch-ready space mission to study an incomer at close quarters.

Some researchers involved in the search for extraterrestrial intelligence (SETI) welcome such studies. “Everyone would be thrilled to get a close-up look” at something like ‘Oumuamua, said astronomer Jason Wright, director of the Penn State Extraterrestrial Intelligence Center.

Others wonder what The Galileo Project will add to ongoing searches for interstellar objects. Alan Fitzsimmons of Queen’s University Belfast, co-leader of the ‘Oumuamua investigation team organised by the International Space Science Institute, noted that existing alert networks already scour telescope data on an hourly basis in search of incoming interstellar objects. He added that the European Space Agency (ESA) is working on a Comet Interceptor mission to launch in 2028 that will sit in orbit waiting for a suitable target, be it a comet or an interstellar object, before rushing out to meet it. “The community can’t wait for the discoveries of the Vera Rubin Observatory,” he says.

Following the recent release of reports on Unidentified Aerial Phenomena (UAP)—including the declassified Pentagon report on UFO sightings published in June this year—the scientific community needs “the determination to systematically, scientifically and transparently look for potential evidence of extraterrestrial technological equipment,” Loeb added.

The Galileo Project will not speculate on previous UAP, alleged sightings, or informal reports, however. Instead, it will analyse data gathered as part of the venture, based on an existing understanding of physics. The international team working on the project includes the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, and Frank Laukien, CEO of the scientific equipment manufacturer Bruker Corporation.

As reported in Dazed, summing up the importance of The Galileo Project, Loeb said: “The impact of any discovery of extraterrestrial technology on science, our technology, and on our entire world view, would be enormous.”
