Our Solar System is very stable. Planets, dwarf planets, asteroids, and comets go forth in their orbit without trouble. But it won't be like this forever. The future of the solar system will have major changes in the Sun and in the planets. We spoke with astronomer Dr Jon Zink to cast our mind's eye far into the future and explore the end of the solar system.

Hinging our happiness on animals known to have a significantly shorter lifespan than our own was, in hindsight, a bad idea. Saying goodbye to a pet is an incredibly painful time in a person’s life, but what if there were a way we could help our pets live longer, better lives?

That’s exactly what Celine Halioua has been exploring as CEO and founder of Loyal, a biotech startup developing drugs to extend dog lifespan. Join host Rachael Funnell as she finds out if science really can help dogs live longer. 

There are many methods that allow us to look back into Earth’s past and study its climate, including the collection of ice cores. Extracting ancient ice from deep inside some of the most remote glaciers can reveal how our planet has changed over millions of years. But it’s not just about the past: what is ancient ice telling us about the future?

Host Dr Alfredo Carpineti spoke with Dr Liz Thomas of the Ice Core Research Group at the British Antarctic Survey to discuss how understanding Earth’s changing climate helps refine our models for the future and how the natural world is responding to the unfolding climate crisis.

The Sun shapes what goes on in space around our planet. Plasma from our star is continuously thrown at Earth in the form of solar winds or coronal mass ejections, changing the shape of the magnetic field, and affecting the atmosphere and anything in it, like the satellites that we depend on. These changes are part of what we call space weather.

Host Dr Alfredo Carpineti spoke to Dr Nigel Meredith of the British Antarctic Survey about what space weather actually is and how it affects us. We even have some incredible recordings of what these space weather events sound like! 

The path beyond the limits of regular computers, even the most powerful supercomputer, lies with the theory of quantum mechanics. Quantum computing promises to change the world, but how do quantum computers work, and how close are we to this fabled new approach to computation?

Host Dr Alfredo Carpineti spoke with Professor Winfried Hensinger, Professor of Quantum Technology at the University of Sussex, to discuss why we need quantum computers, what they would be used for, and why it's taking so long to get them.   

In this age of climate change, habitat loss, and destruction of the natural world, we take an in-depth look at one endangered species in particular: the northern white rhino. Just two females remain in the world and neither are capable of carrying a pregnancy. With such constraints in place, we ask the experts if it's possible to save a species on the very brink of extinction.

Host Eleanor Higgs spoke with Dr Susanne Holtze from the Leibniz Institute for Zoo and Wildlife Research to discuss if and how it might be possible to use genetics research to save the northern white rhino from extinction and whether we should even try.

Space junk is a problem and it’s only set to get worse. In 2018, there were over 2,000 satellites in orbit. Now, thanks to mega-constellations like Starlink, there are 9,000 satellites, and by the end of the decade, this number is expected to reach 60,000. A crowded space environment runs the risk of Kessler Syndrome, where there is so much pollution in orbit that collisions between objects become inevitable, and produce even more space junk.

Host Dr Alfredo Carpineti spoke with space environmentalist Professor Moriba Jah from the University of Texas at Austin to discuss why space junk is such a big deal and how we can make space safe, secure, and sustainable.

Polar bears have long been the poster animal and early warning system for all things climate change. We asked experts what is really going on with the “white hairy canaries” of the Arctic. 

Host Eleanor Higgs spoke with Alysa McCall, Polar Bears International Staff Scientist and Director of Conservation Outreach, on the polar bear monster truck to find out all about the Hudson Bay polar bear population, how “bear-dar” AI is used to protect communities, and to answer the question: How Is Climate Change Affecting Polar Bear Populations?

In the 30 years since the Spielberg movie came out, people from all walks of life have wondered if bringing back dinosaurs is possible, and we couldn’t let the anniversary pass without asking scientists working on dinosaurs and cloning if such a feat is feasible.

IFLScience’s Digital Content Producer Rachael Funnell spoke with Dr. Susie Maidment from the Natural History Museum London and Ben Lamm from Colossal Biosciences to ask a question 66 million 30 years in the making: Is Jurassic Park possible?

For as long as humans have walked this Earth, we have been using chemicals to alter our state of mind. Drugs and alcohol have been used in rituals and medication, for inspiration and escapism, as well as a way to cope with the world. Only in more recent decades have we begun to appreciate the physiological effects that substances have on our brains through science. Host Dr Alfredo Carpineti spoke to neuropsychopharmacologist Professor David Nutt about these effects and a new approach to manufacturing alcohol without the negative consequences.

Computers and supercomputers, whether we like them or not, run our lives. They have revolutionized every aspect of society and we rely on their technology to push beyond our limits. But what about their limits?  What are they, when will we reach them, and can we avoid them? Host Dr Alfredo Carpineti is joined by Professor Mazhar Ali of the Delft University of Technology, whose team has developed a one-way superconductor with exciting applications in computing, to discuss this and more.

What and how we eat plays a huge role in keeping us healthy. The role of diet in helping us when we are fighting off diseases is also enormous, but not discussed often enough. Dr Alfredo Carpineti sat down with Dr William Li to talk about cutting-edge research on how diet helps us stay healthy, and the role it plays in supporting medical treatments. Dr Li is a physician, scientist, president, and medical director of the Angiogenesis Foundation, and author of Eat To Beat Disease: The New Science of How Your Body Can Heal Itself. You can read his book, with plenty of science and recipes, here: https://drwilliamli.com/book-li.

Science can’t be sexist, we hear you cry, it’s methodical, rational. And yet science is carried out by humans who are often a product of the time and place they operate in, struggling to overcome intrinsic biases and outside influence.

Host Katy Evans is joined by zoologist and presenter Lucy Cooke, author of Bitch: A Revolutionary Guide to Sex, Evolution and the Female Animal, to discuss how these biases have affected – and sometimes prevented – what we know about animal biology in some truly eye-opening ways, and hopefully debunk some myths along the way. 

In school, math is one of those polarizing subjects that people either love or hate. For each person complaining they will never use Pythagoras theorem outside of class, there is somebody else pointing out that math is actually about learning skills like problem-solving. In this episode, host Dr Alfredo Carpineti asks a controversial Big Question: "Is math the greatest subject in the world?" To make the case is British mathematician Professor Nira Chamberlain, listed by the Science Council as “one of the UK’s top 100 scientists”. His reasoning should get even the biggest math skeptics on board.  

Every second of every day, whether we’re actively aware of it or not, we’re using our imagination: from what we might have for dinner to life on other worlds. But how can our brains conjure up stuff that we are not looking at or even images of things that don’t exist? Our host Dr Alfredo Carpineti is joined by cognitive scientist Professor Tyler Marghetis from the University of California, Merced to discuss how imagination works, how we can have "Eureka!" moments, and if imagination works the same for everyone.

Everything we see, from galaxies to capybaras, is made of matter. But matter has a mirrored version of itself known as antimatter. If the two come into contact they annihilate one another, turning into pure energy. Why does the universe prefer one over the other? This is a fundamental mystery of the universe, and at the forefront of the search for an answer is the Alpha Experiment at CERN. In this episode, host Dr Alfredo Carpineti is joined by experimental physicist and Alpha spokesperson Professor Jeffrey Hangst to understand the nature of mysterious antimatter.

It’s no secret that species extinction and biodiversity loss are making our environment increasingly less stable. As it feels like we inch closer to waving goodbye to threatened animals like the Javan rhino, a question springs to mind: How do we know when a species is extinct? How, for instance, do we know there aren’t some animals left just hiding in a bush somewhere? In this episode, host Rachael Funnell puts the question to Dr Barney Long of Re:wild, whose mission is the conservation of endangered mammal species and ways of recovering their populations.

We live in a society that idolizes youth for sure, but also with age comes wisdom. However, aging is not all it’s cracked up to be. Could we keep getting older without the drawbacks of being old? Other animals do it, so maybe one day it could apply to humans too. In this episode, host Dr Alfredo Carpineti is joined by Dr Andrew Steele, author of Ageless: The New Science of Getting Older Without Getting Old, to talk about the medical fight against old age at a cellular level and whether humans could ever live forever. 

As the human population increases so too does our demand for food, but in the face of the climate crisis scientists are seeking alternative and sustainable solutions to traditional agricultural practices. In this episode of IFLScience, The Big Questions, we teamed up with BBC Earth to speak with Luca Gamberini of Nemo’s Garden to ask: Is the future of farming underwater?

Nemo’s Garden is working to create an alternative system of agriculture that uses the oceans and other bodies of water to establish a more sustainable way of farming. In this episode, host Rachael Funnell speaks to Gamberini about the complexities of farming underwater and how their innovative agricultural practices could help to protect and conserve the planet.

This episode is presented in partnership with BBC Earth as part of #OurGreenPlanet – an impact initiative that aims to protect our green spaces by sharing the extraordinary stories of people around the globe dedicating their lives to positive change. In association with Moondance Foundation.

Studying the Universe told us the cosmos began with the Big Bang. But how will everything end? In a cold and desolate nothingness? Or will everything collapse back into itself in a Big Crunch? In this episode, host Dr Alfredo Carpineti is joined by theoretical astrophysicist Dr Katie Mack, the Hawking Chair in Cosmology and Science Communication at the Perimeter Institute, who has written extensively about the subject. Together they discuss what the curtain call of the Universe might look like. 

Everything we see and interact with, regular matter, is only a small fraction of what the universe contains. In fact, the vast majority of the universe is invisible to us. We've named these mysterious components dark matter and dark energy, but our understanding of them – and if they even exist – remains lacking. To unravel more of this mystery, Dr Alfredo Carpineti sat down with Dr Mandeep Gill from the Dark Energy Survey collaboration to ask: Will the new generation of upcoming observatories help us understand what the universe is really made of?

Humanity's ever-growing need for energy has led to a world that is dramatically changing, ravaged by extreme weather events. The way we get power has to change. Our question in this episode is about a potential new approach. Can we master nuclear fusion and achieve unlimited energy? Our host Dr Alfredo Carpineti talks to Dr Elise Delchambre of the International Thermonuclear Experimental Reactor (ITER) in France – the world's largest fusion experiment – about nuclear fusion, the many challenges ahead, and how it might change the world. 

Of all the mysteries of the universe, none is closer to us as human beings than this one: what is consciousness? How does our brain turn electrical signals into thoughts and feelings? In this episode, host Dr Alfredo Carpineti and Professor Liad Mudrik from the School of Psychological Sciences And Sagol School of Neuroscience at Tel Aviv University discuss these questions and more as they try and get to the bottom of what is consciousness?

It’s no secret that the planet is getting warmer, but how are our bodies responding to increased exposure to extreme conditions? From record-breaking temperatures to an uptick in severe weather warnings, the consequences of the climate crisis are all around – so how is climate change impacting our health?

This is The Big Question host Rachael Funnell put to author and neuroscientist Clayton Aldern. Author of The Weight of Nature: How a Changing Climate Changes Our Minds, Brains and Bodies, Aldern is well versed in the science that backs up what we know about how extreme weather can alter the way we think, act, and feel.

You can listen to this episode and subscribe to the podcast on all your favorite podcast apps: Apple Podcast, Spotify, Google Podcast, Podbean, Amazon Music, and more. A transcript of the conversation is available here.

The climate crisis is unfolding around us with extreme weather events becoming more common and living organisms having to survive or perish in a changing world. In this episode, host Dr Alfredo Carpineti sat down with Dr Alexandre Kōberle, a research fellow at the Grantham Institute for Climate Change, to discuss how we got here, how we can avoid the worse case scenarios, what political will is needed, and if there are ways to actually fix the mess we are in? 

From extraterrestrial intelligence to simple life forms, the Universe might be teeming with life. Can we find and communicate with these life forms? IFLScience spoke to Dr Seth Shostak, Senior Astronomer at the SETI Institute to tackle the fundamental question: are we alone in the Universe?

A little teaser for our upcoming podcast

Homo sapiens – us – are the only surviving human species. The question, and it is a big one, is why? Who were the species that came before us, or lived alongside us, and what happened to them?

Host Dr Alfredo Carpineti is joined by Professor Chris Stringer, human evolution research lead at the Natural History Museum, London, to explore the journey that we and the other human species took to end up here.

Here is a little teaser for our brand new podcast: Break It Down! Coming soon to a podcast app near you...

During the holiday season, many of us will be tucking into delicious meals which may well include a whole host of meats. But have you ever thought about going meat-free this time of year? With concerns over the impact of meat consumption on the planet, thoughts are turning to the future of the industry and how the tastes and textures that many people enjoy can be replicated in meat-free alternatives.

In a bonus holiday episode of IFLScience The Big Questions, available on all platforms, host Eleanor Higgs speaks with Daniel Dikovsky, chief technology officer at Redefine Meat, to find out how scientists and engineers are working to create plant-based, 3D-printed meat alternatives without the environmental impact.

Solar activity goes through cycles. The main one is about 11 years long and its maximum is marked by powerful eruptions of electromagnetic radiation known as solar flares, as well as releases of plasma known as coronal mass ejections. The most powerful known flare happened in 1859 and led to telegraph stations catching fire across the US, and Northern and Southern Lights becoming visible in the tropics.

Host Dr Alfredo Carpineti spoke with Dr Ryan French, astronomer at the National Solar Observatory and author of The Sun: Beginner's Guide to Our Local Star, to find out about solar flares and what would happen if a massive one took place today.

The climate crisis is affecting glaciers across the world in myriad ways. Dramatic melting, steep declines, and overall reduction in mass are some of the changes seen in both polar glaciers and the mountainous peaks of every continent. Understanding these changes requires understanding how we monitor these enormous ice masses. The health of glaciers affects the well-being of the populations living near them, but they have far-reaching consequences, such as global sea level rise. 

Host Dr Alfredo Carpineti spoke with Dr Peter Davis from the British Antarctic Survey about Thwaites Glacier in Antarctica, otherwise known as the "Doomsday Glacier". Thwaites is Antarctica's most endangered glacier and studying it is of global importance. 

As much as everyone enjoys flying abroad for their holidays, the cost of the climate impact might be making people think twice. So what can we do? Aside from paying to offset the carbon, the emergence of a new industry is hoping to change the way we fly. Sustainable aviation fuels (SAFs) or e-fuels are looking to replace traditional fuels as a much greener alternative, but there’s still a long way to go.

Host Eleanor Higgs spoke with Sophie Zienkiewicz and Alasdair Lumsden, co-founders of Carbon Neutral Fuels, to find out if it might be possible to replace the fuel in our airplanes, capture carbon from the world around us, and provide a carbon-neutral alternative when we take to the sky.

Where do baby dinosaurs come from? It’s a question that’s been burning in the collective brain of the IFLScience team for some time. In this episode, host Rachael Funnell speaks with science writer and palaeontologist Riley Black to find out what science has discovered so far about the sex lives of dinosaurs.

Coming soon: join IFLScience as we explore the questions nobody thought to ask but everyone wants the answers to. Get the behind-the-scenes conversations from CURIOUS magazine’s We Have Questions interviews, as we hunt down the experts to answer some of science’s stranger questions. Until then, catch up with the E-magazine here: https://www.iflscience.com/curious-magazine

Antibiotic resistance is a major health concern. We now have several harmful microbes that have evolved into versions unaffected by common treatments. To find new antibiotics scientists are looking further afield, including in the ocean.

Host Dr Alfredo Carpineti speaks to Dr Sam Afoullouss, a marine scientist at the University of South Florida, about the interesting chemistry found in the deep sea and its potential to be the pharmacy of the future.  

Are humans done evolving – or could settling on an alien world with an environment unlike Earth’s take us on a different evolutionary trajectory?

Host Tom Hale is joined by Scott Solomon, author and professor of bioscience at Rice University, to discuss the myriad ways Homo sapiens may continue to evolve on Earth, and how future human settlements on Mars might influence our species’ evolution.   

It’s no secret that octopuses are intelligent – but are they sentient? And how is that reflected in the way that they’re treated?

Host Rachael Funnell is joined by Sy Montgomery, author of Secrets of the Octopus, and Sophika Kostyniuk, Managing Director at the Aquatic Life Institute, to discuss the evidence for octopuses’ sentience, and how that could impact the rights they’re afforded in science, agriculture, and the wider world.

Welcome to IFLScience’s first-ever Halloween podcast special, bringing you a feature-length episode of The Big Questions as we take on the UK’s most haunted castle. We journeyed to Northumberland up by the Anglo-Scottish border to spend the night in Chillingham Castle, a place that allegedly boasts an above-average number of ghosts. We wanted to explore what attracts people to sites such as this one, even inspiring folks to gear up with a host of ghost-hunting tools and try and communicate with spirits, despite the fact we’ve yet to find any evidence for their existence.

At IFLScience, we don’t do things by halves, so we threw it all at the wall: Ouija boards, dungeon immersion, dowsing rods, spirit boxes, and just a bit of old-fashioned wandering around in the dark. We also spoke to Emeritus Professor Chris French, an expert in anomalistic psychology, and the founders of the Recreational Fear Lab to top up on the science of fear and better understand why it is the paranormal has us all in such a choke hold.

So, join IFLScience's Chris Carpineti, Dr Beccy Corkill, Rachael Funnell, and Dr Russ Moul as they journey into the unknown in this very special episode of The Big Questions.

It’s the holiday season, and what better time to gather your loved ones together and absolutely trounce them in an hours-long board game marathon?

Humans have been playing and enjoying competitive games for centuries. For this special episode of The Big Questions, host Laura Simmons sat down with Kelly Clancy, neuroscientist and physicist, and author of recent book Playing with Reality: How Games Shape Our World, to find out more about why we love competition so much, and what our long history of gameplaying together can teach us about each other – and ourselves. 

We're back! Here's what to expect this season, starting June 19, 2025. If you missed any previous episodes, catch up here: IFLScience The Big Questions

The expanse of space and the oceanic abyss hold a fascination for humanity; extreme environments where our bodies and technology are pushed to their limits, yet we continue to explore. We take this tongue-in-cheek question seriously and pose it to astronauts and explorers who have done both.

Join co-hosts Dr Alfredo Carpineti and Katy Evans as they share insights from space travellers and deep-sea visitors Luca Parmitano, Dr Kathy Sullivan, and Victor Vescovo on the challenges and rewards of exploring space and the deep ocean. 

Of all the celestial bodies, none induce awe and fear in equal measure quite like black holes. They are incredible astrophysical objects and there are plenty of reasons why they are so iconic. In their supermassive form in particular, they have influenced the formation and evolution of galaxies, and more. 

Host Dr Alfredo Carpineti sat down with astrophysicist, science communicator, and author Dr Becky Smethurst, to ask: How do black holes shape the universe?

While climate change, species extinctions, and increasing carbon dioxide levels might feel like media buzzwords at this point, they all remain very real threats to biodiversity across the globe, and by extension, the future of our planet. Some have even argued that these are warning signs that we are living through a sixth mass extinction.

Host Eleanor Higgs discusses Earth’s previous mass extinctions with palaeontologist Professor Michael Benton from the University of Bristol, and how we can use this history as a basis to understand what is happening again right before our eyes – and what might be done to stop it.

Language can evolve surprisingly quickly, and nothing has sped it up quite like the invention of the Internet. So, how does it affect how we communicate, not just on our devices but offline, IRL?

Join host Tom Hale, senior journalist at IFLScience, as he discusses this and more with Internet linguist Dr Gretchen McCulloch, where they explore the origins of internet acronyms, interpreting tone via emojis, memes in real life, and the universal need for ironic punctuation marks. 

Lining up for your seasonal flu shot is an annual ritual, but what if it didn't have to be this way? Wouldn't it be great if we could develop a universal vaccine that could protect us against all current and future virus strains? Host Laura Simmons speaks to Dr Florian Krammer, a professor in vaccinology at the Icahn School of Medicine at Mount Sinai, to find out just how far humanity has reached in our quest to finally conquer the flu with an all-purpose vaccine.

Today’s rubbish may well be the fossils of tomorrow. Plastic bags, old pens, cheap clothing, or even chicken bones are all examples of possible “technofossils”, rapidly accumulating debris and detritus that may come to represent the story of humanity in the geological record long after we’re gone.

But it doesn’t have to be this way. Host Dr Russell Moul speaks to Professors Sarah Gabbott and Jan Zalasiewicz of the University of Leicester, authors of Discarded: How Technofossils Will be Our Ultimate Legacy, about the fascinating processes involved in turning our trash into fossils, but also how interest in these processes may help us change them.

In March 2024, geologists rejected the proposal that we are in a new geological era: the Anthropocene, a time dominated by human activity on the planet. And yet, the evidence of our impact on the Earth’s ecology and climate continues to mount up around us. So how could this decision make sense given everything going on in the world today?

To dig through the layers of confusion surrounding the Anthropocene, host Dr Russell Moul spoke to Professor Erle Ellis, from the Department of Geography and Environmental Systems at the University of Maryland, Baltimore County. He explains how the idea of the Anthropocene was created and how it has value outside of debates over geological time.

De-extinction. It’s not a word many of us were thinking about just a decade ago, but it’s one that we’re getting ever more familiar with. The de-extinction company Colossal Biosciences has set its sights on de-extincting 5 key species whose extinction is thought to have either been caused, or heavily contributed to, by humans: the woolly mammoth, thylacine, dodo, moa, and dire wolf.

By their definition of “functional de-extinction,” they’ve already brought back the dire wolf, and have set a goal to see a living, breathing mammoth by 2028, but what do they mean by de-extinction, and what can it realistically achieve?

In this episode of The Big Questions, writer Rachael Funnell goes on a deep dive into de-extinction, speaking with Colossal’s co-cofounder Ben Lamm, chief science officer Beth Shapiro, and chief animal officer Matt James. We also hear from historian Professor Sadiah Qureshi, author of Vanished: An Unnatural History Of Extinction, who raises some interesting questions we should all be asking ourselves as this curious new branch of science marches on – both in its efforts to bring back creatures from the past, and to prevent further extinctions in the future.

Time is everything to us: in terms of physical laws, in how we experience the world, and how society works. Still, its true nature remains beyond us. As scientists search for a deeper understanding, the way humans relate to time has changed massively.

To explore the questions of what time is and how we measure it, host Dr Alfredo Carpineti is joined by Dr Emily Akkermans, Curator of Time at the Royal Observatory Greenwich, which is celebrating its 350th anniversary this year.
