Let there be Life

   2014    Science
Professor of physics Jim Al-Khalili investigates the most accurate and yet perplexing scientific theory ever - quantum physics, the perplexing theory of sub-atomic particles. Turning his attention to the world of nature, can quantum mechanics explain the greatest mysteries in biology? The European robin navigates using one of the most bizarre effects in physics - quantum entanglement, a process which seems to defy common sense. Jim finds that even the most personal of human experiences - our sense of smell - is touched by ethereal quantum vibrations. According to new experiments it seems that our quantum noses are listening to smells. Jim discovers that the most famous law of quantum physics - the uncertainty principle - is obeyed by plants and trees as they capture sunlight during the vital process of photosynthesis. Jim wonders if the strange laws of the sub-atomic world, which allow objects to tunnel through impassable barriers in defiance of common sense, could effect the mechanism by which living species evolve?

Is the Force With Us

   2017    Science
Morgan Freeman continues to challenge audiences to think about daring topics in the last season of Through the Wormhole. In the part 1, new research is beginning to reveal a hidden force in the universe - one that penetrates space with trillions of invisible connections, instantly linking every place in our world and joining our future with our past. Is the Force with us?

Can Time Go Backwards

   2015    Science
We move around in space, but we are stuck in a prison of time moving ever forwards. Einstein said, 'The distinction between past, present and future is only a stubbornly persistent illusion.' Is our experience of the ticking clock merely a trick of the mind? Could science ever make the clock move backwards? Experiments in quantum physics are showing that the future influences the present: what happens later limits the choices we think we have now. The laws of physics say visiting or talking to ourselves in the past is possible – but changing history once we get there is not.

Microscopic Universe

   2012    Science
The key to understanding the universe seems to be understanding its smallest components. But the quantum realm bears little resemblance to the universe we know. Image a particle that can be many places at the same time and communicate changes instantly across vast distances, even to the other side of the Universe. Shrinking down billions of times, into the realm of atoms and sub-atomic particles, takes us into a bizarre world of paradoxes and multiverses. Explore with us quantum physics and the potential applications in computer science.

The Hunt For Higgs

   2012    Science
Go with us behind the scenes at CERN to follow one of the most epic and expensive scientific quests of all time: the search for the Higgs particle, believed to give mass to everything in our universe. However, the hunt for Higgs is part of a much grander search for how the universe works. It promises to help answer questions like why we exist and is a vital part of a Grand Unified Theory of nature". At the heart of the pursuit of the elusive particle is the same feature that makes snowflakes beautiful and human faces attractive: the simple and enchanting idea of symmetry. Presenter Jim Al-Khalil

Secret Lives of Neutrinos

   2021    Science
Our world, our solar system, our universe, none of it would exist without a ghostly particle called the neutrino. They are our early warning system whenever there's trouble in the universe. Neutrinos trigger star-killing explosions, supernovas. Neutrinos can answer so many questions, from why do we exist to how was the universe created. Neutrinos can be the very reason that we exist at all. The more we understand these elusive particles, the more we can gain insight into how the universe works.
