As we step into the promising yet enigmatic year of 2026, one can’t help but wonder: What groundbreaking discoveries will physics unveil next? Predicting the future of science is no small feat—it’s like trying to solve a puzzle with pieces that haven’t been invented yet. But fear not, because while we can’t foresee every twist and turn, we can certainly highlight the trends and topics that are setting the stage for an exciting year ahead. And this is the part most people miss: the beauty of science lies in its uncertainty. If we already knew all the answers, the journey of discovery would lose its thrill. So, what’s in store for 2026? You’ll have to keep reading Physics World to find out—but let’s give you a sneak peek.
Every December, I’d challenge myself to forecast the next year’s physics highlights—potential breakthroughs, emerging trends, and the trailblazers who might make headlines. Yet, it quickly became clear that predicting scientific advancements is more art than science, often teetering on the edge of futility. Sure, we know when space missions are scheduled to launch or when particle colliders and light sources will come online, but beyond that, the landscape is shrouded in mystery. But here’s where it gets controversial: Is this uncertainty a hurdle or the very essence of scientific exploration? Let us know your thoughts in the comments!
Amid the tumultuous landscape of U.S. science—a topic deserving of its own deep dive—Physics World Live is here to guide you through the hottest topics in physics today. Kicking off the series is an online panel on quantum metrology, a rapidly growing field ensuring that quantum technologies are tested, validated, and brought to market. While the International Year of Quantum Science and Technology officially wraps up in February with a closing ceremony in Ghana, its ripple effects will undoubtedly shape 2026. But here’s a thought-provoking question: As quantum tech advances, how will it redefine industries and everyday life? Share your predictions below!
Another highlight is our online event on nuclear fusion, the holy grail of limitless clean energy and a potential game-changer for the climate crisis. Yet, the path to commercialization is fraught with challenges, despite the efforts of private firms like Tokamak Energy, which recently won a Business Award from the Institute of Physics (IOP). These companies are working alongside the colossal ITER experiment in southern France, but will their combined efforts be enough? And this is the part most people miss: Fusion’s promise is immense, but its hurdles are equally daunting. What’s your take on its future?
Medical physics will also take center stage in 2026, with an online panel featuring current and past editors-in-chief of Physics in Medicine & Biology, a journal celebrating its 70th anniversary this year. Published by IOP Publishing, the panel will explore the field’s evolution and its critical role in advancing medicine and biology. Additionally, the IOP is launching an ‘impact project’ focused on medical physics, alongside another on artificial intelligence (AI). They’ll also continue their work on metamaterials, a field pioneered by visionaries like Imperial College’s John Pendry. Could a Nobel Prize be on the horizon for him this year? That’s one prediction I’d love to see come true.
From quantum leaps to fusion dreams, 2026 is shaping up to be a year of unparalleled excitement in physics. On behalf of the entire Physics World team, we wish you a happy, curious, and successful year ahead. Your support means the world to us—thank you for being part of this journey. Now, tell us: What are you most excited to see in physics this year? Let the discussion begin!
