Probably the only thing that is constant about the Hubble Constant is that it keeps changing! What is it? Why is it such a hot topic in cosmology today and why are some even calling it a "crisis"? Come along with Wayne and Dan as they dive into the quest for the elusive magic number. What does it mean for cosmology and what might it all have to do with the way God made the universe?

Dr. Jo Dunkley is a Professor of Physics and Astrophysical Sciences at Princeton University and author of the book Our Universe: An Astronomer's Guide. Jo is a cosmologist, and her job is to study the universe. She conducts research to try to approximate how space behaves as a whole. This includes looking into space and taking measurements to determine how the universe began, what it's made of, how it's growing, and what is going to happen to it in the future. Physics and family are two of the major pieces in Jo's life. She loves spending time with her two daughters, while they run, draw, sing, and learn about space. She received her MSci with First Class Honors in Natural Sciences from the University of Cambridge and her PhD in Astrophysics from the University of Oxford. Afterwards, she conducted postdoctoral research and was subsequently a Visiting Research Fellow at Princeton University. Before joining the faculty at Princeton University, Jo served on the faculty at the University of Oxford. Over the course of her career, Jo has received numerous awards and honors including the Maxwell Medal from the Institute of Physics, the Royal Astronomical Society's Fowler Prize in Astronomy, the Royal Society Rosalind Franklin Award, the Royal Society Wolfson Merit Award, and the Philip Leverhulme Prize from the Leverhulme Trust. She also shared the Gruber Foundation Cosmology Prize, a NASA Group Achievement Award, and most recently the Breakthrough Prize for Fundamental Physics with the Wilkinson Microwave Anisotropy Probe team. In our interview, Jo speaks about some of her experiences in life and science.

Taking a telescope to the night sky and a critical eye to our past, astrophysicist Jo Dunkley explores the universe while unearthing a line of stellar female astronomers who ran the risk of being consigned to the black hole of history. Hosted by Rae Johnston.
Jo Dunkley is professor of physics and astrophysical sciences at Princeton, a full professor at Oxford at 35. She has won awards from the Royal Astronomical Society, the Institute of Physics, and the Royal Society for her work on the origins and evolution of the Universe. In Our Universe , cosmologist Jo Dunkley clearly explains many of the big things we know about the universe, and how scientists came to discover them, from black holes, to distant galaxies, expanding space, and more. Complemented by simple, effective illustrations of complex astrophysical concepts and techniques, Our Universe is an engaging introduction to the nature of our cosmic home. She talks to Ed Andrew on Human Impact about working with NASA, how billion dollar science projects transfer technology into humanity and her work to increase female and racial diversity in science.
Jo first came to Princeton as a postdoc in 2006, when she worked on data from the Wilkinson Microwave Anisotropy Probe (WMAP), a space telescope that took the universe’s earliest baby pictures. When she ran her code on that data, she was briefly the only person in the world to know the precise age of … Continue reading "Jo Dunkley: On studying the origins of the universe — and sharing her love of space with the public"
Dr. Jo Dunkley is a professor of Physics and Astrophysical Sciences at Princeton University. Her research is in cosmology, studying the origins and evolution of the universe. She holds a Ph.D. in astrophysics from University of Oxford. Jo had an interesting path to her Ph.D. Her earliest love was mathematics, and soon she realized she could use math to answer questions about the real world. That led to a love for physics (at Cambridge) and getting her Master’s. While there, she discovered relativity and astrophysics, but another event inspired her to go for a Ph.D. In the second segment, we chatted about her true love, using computer code on supercomputers to model the universe and analyzing the Cosmic Microwave Background (the detectable aftermath of the Big Bang). Also discussed: inflation theory, dark matter and theories of the Multiverse.

Jo Dunkley is a professor of physics and astrophysical sciences at Princeton University. Hannah Devlin talks to her about what it’s like to work on the Atacama Cosmology Telescope in Chile, where they need to bring oxygen tanks for safety.
How often have you laid under a night sky and wondered what is or might be out there in the endless tracts of space? Are there neutrinos passing through your body as you lay there? Are there places just like earth far beyond what you can see…are there other beings there, and will we ever be able to converse with them – or do we need to fear them? We delve into some of those thoughts on today’s Perspective. Guest: Dr. Jo Dunkley, professor of physics and astrophysical sciences at Princeton University. Perspective is a weekly public affairs program hosted by Richard Baker, communications professor at Kansas State University.

Two astronomical questions today sent in to curiouscases@bbc.co.uk for Drs Hannah Fry and Adam Rutherford to answer. The Cosmic Speed Limit "We often read that the fastest thing in the Universe is the speed of light. Why do we have this limitation and can anything possibly be faster?" asks Ali Alshareef from Qatif from Saudia Arabia. The team grapples with Einstein's Special Theory of Relativity, with help from cosmologist Andrew Pontzen and a British train, travelling somewhat slower than the speed of light. Plus physicist and presenter Jim Al-Khalili describes how he nearly lost his boxer shorts in a daring bet concerning the speed of subatomic particles. The Cosmic Egg "How do we measure the age of the Universe?" asks Simon Whitehead. A hundred years ago this wouldn't even have been considered a valid question, because we didn't think the Universe had a beginning at all. Even Einstein thought that space was eternal and unchanging. This is the tale of how we discovered that the Universe had a beginning, and why calculating its age has been one of the greatest challenges in modern astronomy. We also uncover the mysterious dark energy that pervades the cosmos and discover why it's been putting a scientific spanner in the works. Helping to unravel today's question are physicists Andrew Pontzen, Jo Dunkley and Jim Al-Khalili.

Does space go on for ever? Are there infinitely many stars? These are some of the questions Adrian Moore explores in this episode in his series about philosophical thought concerning the infinite. With the help of the theories of the Ancient Greeks through to those of modern cosmologists, Adrian examines the central question of whether our universe is finite or infinite. For most of us, looking up at the stars gives us a sense of infinity but, as Adrian discovers, there is a strong body of opinion which suggests that space is finite, albeit unbounded. This is a difficult idea to grasp, but by inviting us to think of ourselves as ants, astrophysics professor Jo Dunkley attempts explain it. Adrian also tackles the idea of the expanding universe and the logic that leads cosmologists to argue that it all started with a big bang, and may all end with a big crunch. Finally, we discover from cosmologist John Barrow how the appearance of an infinity in scientists' calculations sends them straight back to the drawing board. The infinite, which the Ancient Greeks found so troubling, has lost none of its power to disturb. A Juniper production first broadcast on BBC Radio 4 in September 2016.
