How Iran shut down the internet

On January 8, as thousands of Iranians took to the streets in nationwide protests, the government cut off the internet. Under cover of digital darkness, the Iranian regime launched a brutal and deadly crackdown against anti-government protesters. After three weeks of internet blackout, reports from web traffic monitor Netblocks suggest that the internet is slowly coming back online but predominantly for government-approved users. Yet for most of the shutdown, banks and some local government websites and apps still worked. And that’s because Iran is developing its own, national internet, cut off from the rest of the world. In this episode, we speak to Amin Naeni, a PhD candidate researching digital authoritarianism at Deakin University in Australia, about how Iran built one of the world’s most sophisticated systems of digital control. This episode was written and produced by Mend Mariwany and Gemma Ware with editing help from Katie Flood. Mixing by Michelle Macklem and theme music by Neeta Sarl.

How the US cloned Iran's drones

The day after the US began bombing Iran, US Central Command confirmed it had used a new, cheap type of kamikaze drone called a Lucas for the first time in a combat operation. These drones were made in America, but their roots actually lie in Iran – they are reverse engineered copies of an Iranian drone called a Shahed that the Russians have also been using to bomb Ukraine. In this episode, PhD researcher and military expert Arun Dawson at King's College London explains how the Iranians developed the Shaheds, why the US decided to copy them, and what role these low-cost drones might play in the future of warfare. This episode was written and produced by Mend Mariwany and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

Artemis II: NASA’s long road back to the Moon

Final preparations are underway for NASA’s Artemis II mission, the first crewed mission around the Moon for more than 50 years. Four astronauts, three men and one woman, will spend 10 days aboard the Orion spacecraft, going further into space than any other humans as they orbit the Moon and return to Earth. The mission is the next step of the Artemis programme, which plans to land astronauts back to the Moon by 2028. China has its own programme targeting a full crewed mission to the lunar surface by 2030. In this episode, we speak to Scott Pace, director of the Space Policy Institute at George Washington University about why the US is going back to the Moon. Pace worked in space policy for the George W. Bush Administration, followed by a stint at NASA before his appointment as the executive secretary of the National Space Council during the first Trump administration, where he worked on the launch of the Artemis programme.

Is there a multiverse?

Interest in the multiverse theory, suggesting that our universe is just one of many, has spiked since the movie Everything Everywhere All At Once was released. The film follows Evelyn Wang on her journey to connect with versions of herself in parallel universes to stop the destruction of the multiverse. The multiverse idea has long been an inspiration for science fiction writers. But does it have any basis in science? And if so, is it a concept we could ever test experimentally? Featuring Andrew Pontzen, professor of Cosmology at University College London, Katie Mack, Hawking chair in cosmology and science communication at the Perimeter Institute for Theoretical Physics, and Sabine Hossenfelder, research fellow of physics at the Frankfurt Institute for Advanced Studies. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware. Social media and platform production by Alice Mason, sound design by Eloise Stevens and music by Neeta Sarl. A transcript is available here.

Theory of everything: do we really need one?

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everything? And are we anywhere near achieving one? Featuring Vlatko Vedral, a professor of physics at the University of Oxford and Chanda Prescod-Weinstein, an assistant professor in physics and astronomy and core faculty in women's and gender studies at the University Of New Hampshire.

The 'national humiliation' behind Russia's war on Ukraine

As the 21st century dawned, a newly-elected Vladmir Putin was making friends on the world stage. He smiled for photo ops at G8 meetings, and was the first foreign leader to call George W. Bush after the attacks of 9/11, offering his support against terrorism. So what changed? To understand Russia's view of the world now – and its continued aggression towards Ukraine – it helps to know more about the psyche of the country and its leader. In today's episode, we talk to James Rodgers, a reader in international journalism at City St George's, University of London, about how a festering sense of national humiliation after the collapse of the Soviet Union hardened Putin's tough man regime and led Russia to turn its back on the west. This episode was written and produced by Mend Mariwany and Gemma Ware with editing help from Ashlynne McGhee. Mixing by Michelle Macklem and theme music by Neeta Sarl.

A lost US military base under Greenland's ice sheet

In the summer of 1959, a group of American soldiers began carving trenches in the Greenland ice sheet. Those trenches would become the snow covered tunnels of Camp Century, a secret Arctic research base powered by a nuclear reactor. Camp Century operated for six years, during which time the scientists based there managed to drilling a mile down to collect a unique set of ice cores. But by 1966, it had been abandoned, deemed too expensive and difficult to maintain. Today, Donald Trump’s territorial ambitions for Greenland continue to cause concern and confusion in Europe, particularly for Denmark and Greenlanders themselves who insist their island is not for sale. One of the attractions of Greenland is the gleam of its rich mineral wealth, particularly rare earth minerals. Now that Greenland’s ice sheet is melting due to global warming, will this make the mineral riches easier to get at? In this episode, we talk to Paul Bierman, a geologist and expert on Greenland’s ice at the University of Vermont in US. He explains why the history of what happened to Camp Century – and the secrets of its ice cores, misplaced for decades, but now back under the microscope – help us to understand why it’s not that simple.

Is time an illusion?

Without a sense of time, leading us from cradle to grave, our lives would make little sense. But on the most fundamental level, physicists aren't sure whether the sort of time we experience exists at all. We talk to three experts and find out if time could potentially be moving backwards as well as forwards. Featuring Sean Carroll, Homewood professor of natural philosophy at Johns Hopkins University, Emily Adlam, postdoctoral associate of the philosophy of physics at Western University and Natalia Ares, Royal Society university research fellow at the University of Oxford. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Will we ever have a fundamental theory of life and consciousness?

What’s the difference between a living collection of matter, such as a tortoise, and an inanimate lump of it, such as a rock? They are, after all, both just made up of non-living atoms. The truth is, we don’t really know yet. Life seems to just somehow emerge from non-living parts. Featuring Jim Al-Khalili, professor of physics at the University of Surrey and Sara Imari Walker professor of physics at Arizona State University. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Great Mysteries of Physics - trailer

"There is nothing new to discover in physics", declared the British physicist Lord Kelvin in 1900. That is no longer true. Today it is becoming increasingly clear that there are problems that physics, as we know it, doesn't seem to be able to solve. Perhaps we just need more data, perhaps we need a new fundamental theory of reality. In this six-part series, host Miriam Frankel from The Conversation will take you on a mind-blowing journey from the smallest to the largest conundrums, exploring curled-up dimensions, consciousness and parallel universes along the way. We will discover the greatest mysteries facing physicists today – and discuss the radical proposals for solving them. The first episode will be available on March 8. Great Mysteries of Physics is produced by Hannah Fisher with sound design by Eloise Stevens. You can sign up to The Conversation’s free daily email here. Great Mysteries of Physics is a podcast series supported by FQXi.
