IFLScience - The Big Questions

How Will The Universe End?

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. 

What Is The Universe Made Of?

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?

Can We Achieve Unlimited Energy?

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. 

What Is Consciousness?

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?

Can We Stop Or Reverse Climate Change?

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? 

Are We Alone In The Universe?

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?
