The universe is so much bigger than what people can see. Visible matter — the ground, the Sun, the screen you're reading this on — makes up only about 4 or 5 percent of our known universe. Dark matter makes up much more of the universe. It's all around us even though we can't see it. So what is it? What's it made out of? How do we even know it exists? Host Emily Kwong and Rebecca Ramirez try to find out with the help of astrophysicist Priyamvada Natarajan. This episode is part of our series Space Camp, all about the weird and mysterious depths of our universe.

Is 'energy' as a concept suited to the 21st century? Or is it a simplification of processes we do not understand, whose nature may be more mystical rather than purely rational?Looking for a link we mentioned? It's here: https://linktr.ee/philosophyforourtimesJoin leading minds in the world of physics - Priyamvada Natarajan, Avshalom Elitzur, and Bernard Carr - as they face head on the necessity, or lack thereof, of one of the most essential building blocks of contemporary physics: energy. It underlies our universe, and yet its versatile nature is still not entirely understood, for example in its mysterious manifestation as 'dark energy'. In this honest talk, three leading scientists discuss this and other issues, as well as their embrace of mysticism in the search for an underlying physical truth.

A new ESA telescope could help us understand how dark matter and dark energy influence the structure of the universe. Also, using both JWST and the Chandra Observatory, astronomers discover the oldest known black hole.Euclid Telescope's First Images UnveiledThis week, the European Space Agency unveiled the Euclid space telescope's first full-color images of the cosmos. The telescope has a wide field of view and is designed to take images of large swaths of the sky in both visible and infrared light. The telescope's designers hope that they will be able to create a detailed 3D map of the cosmos over the next six years and, with that map, begin to sort out the influences of dark matter and dark energy on the basic structure of the universe.Sophie Bushwick, technology editor at Scientific American, joins Ira to talk about the first images from the Euclid telescope and other stories from the week in science. They'll try to explain the recent conversation about ultraprocessed foods and discuss steps toward regulating AI coming from the Biden administration and a host of other countries; a move to rename some North American birds; and the tale of a fish that uses electrolocation and some shimmies to get a 3D map of its environment.Not Just Dying Stars: A Black Hole That Came From GasThis week, astronomers confirmed that they had found the oldest known black hole, thanks to the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory. The supermassive black hole formed when the universe was still a toddler, just 470 million years after the Big Bang. But its age isn't the only thing that makes it unusual.Astronomers long thought that the only way a black hole could form was through the collapse of a star. But this week's discovery confirms a theory that some black holes at this early stage in the universe formed from the condensation of clouds of gas. The theory purports that such black holes would produce superheated x-ray-emitting gas. Now, data from JWST and Chandra have helped confirm these x-ray signals from the newly discovered black hole. The findings are available via preprint and have been published in the journal Nature Astronomy.Ira sits down with Dr. Priyamvada Natarajan, a professor of astronomy and physics at Yale who helped develop this theory, to talk about how these unique black holes change our understanding of the early universe.To stay updated on all things science, sign up for Science Friday's newsletters.

In 1908, on a sunny, clear, quiet morning in Siberia, witnesses recall seeing a blinding light streak across the sky, and then … the earth shook, a forest was flattened, fish were thrown from streams, and roofs were blown off houses. The “Tunguska event,” as it came to be known, was one of the largest extraterrestrial impact events in Earth's history. But what kind of impact – what exactly struck the earth in the middle of Siberia? – is still up for debate. Producer Annie McEwen dives into one idea that suggests a culprit so mysterious, so powerful, so … tiny, you won't believe your ears. And stranger still, it may be in you right now. Or, according to Senior Correspondent Molly Webster, it could be You.EPISODE CREDITS Reported by - Annie McEwen and Molly WebsterProduced by - Annie McEwen and Becca Bresslerwith help from - Matt KieltyOriginal music and sound design contributed by - Jeremy Bloom, Annie McEwen, Matt KieltyMixing by - Jeremy Bloomwith dialogue mixing by - Arianne WackFact-checking by - Diane Kellyand edited by  - Alex Neason GUESTS Matt O'Dowd (https://www.mattodowd.space/)Special Thanks:  Special thanks to, Matthew E.

The universe is so much bigger than what people can see, and astrophysicist Priyamvada Natarajan is trying to figure out that which we can not see. Producer Rebecca Ramirez talks with Priya and reports on the theory about some of the secret scaffolding of the universe: dark matter.

Priyamvada Natarajan is a Professor in the Departments of Astronomy and Physics at Yale University. She is a theoretical astrophysicist interested in cosmology, gravitational lensing and black hole physics. Her research involves mapping the detailed distribution of dark matter in the universe exploiting the bending of light en-route to us from distant galaxies. You can read her writing in the New York Review of Books, the Wall Street Journal, and the New York Times. On this episode, she sits down with James Ryerson to discuss her career as a scientist and writer, her thoughts on science communication and the philosophy of science, and her New York Times piece, "At Long Last, a Glimpse of a Black Hole", published in April 2019. You can find Prof. Natarajan on Twitter at @SheerPriya, Line Edit at @the_line_edit, and Joseph Fridman at @joseph_fridman. Supported by the John Templeton FoundationHosting and production by James RyersonEditing and production by Joseph FridmanTheme composition by Stephen LaRosa of Wonder Boy AudioLogo design by Jacob Feldman and Joseph FridmanSpecial thanks to Dave DeSteno, Lisa Feldman Barrett, and the Department of Psychology at Northeastern University.

Dr. Priyamvada Natarajan is an expert on the strangest things in physics: warped space, dark matter, dark energy, and even questions from our listeners. See omnystudio.com/listener for privacy information.

Eric Cornell in conversation with Priyamvada Natarajan. The notion of imperfection usually carries negative implications and the idea of defect. But what is the significance and implication of the concept of imperfections in the field of physics? How did it impact our universe? Eric Cornell, Professor of Experimental Physics from the University of Colorado and Nobel Laureate for Physics in 2001, speaks with distinguished astrophysicist Priyamvada Natarajan and evaluates the one moment in time 14 billion years ago that made it possible for us to be here today. This episode is the audio version of a live online session from #JLFColorado2020.

Black holes are one of the most beguiling objects in our universe. What are they exactly? How do they affect the universe? And what would it be like to fall into one? We venture beyond the point of no return with Yale astrophysicist Priyamvada Natarajan, into a fascinating world of black holes — where the laws of physics break down. (Encore episode.)

Dr. Priyamvada Natarajan is a cosmologist and theoretical astrophysicist from Yale University, specializing in dark matter, dark energy, and black holes. Her current job is to 'map' Dark Matter and her new book provides a tour of the “greatest hits” of cosmological discoveries—the ideas that reshaped our universe over the past century.

Dr. Priyamvada Natarajan is a cosmologist and theoretical astrophysicist from Yale University, specializing in dark matter, dark energy, and black holes. She also holds the Sophie and Tycho Brahe Professorship of the Dark Cosmology Centre, Niels Bohr Institute, at the University of Copenhagen, Denmark. She is passionate about sharing science with the general public and in her new book she provides a tour of the “greatest hits” of cosmological discoveries—the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan is at the forefront of this research—an astrophysicist who literally creates maps of invisible matter in the universe. In the book, she not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes—these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe.

In her new book Mapping the Heavens: The Radical Scientific Ideas That Reveal the Cosmos, Priyamvada Natarajan ’91, SM ’11 tells the stories of Einstein’s troubles with gravity, an expanding universe, and dark matter. For Natarajan, a professor of physics at Yale University, Einstein is just one of a cast of characters in 20th century astronomy and cosmology whose struggles are at times amusing and at other times most inspiring.

No one thinks longer, or bigger, than astrophysicists. “This is the golden age of cosmology,” says Priya Natarajan, one of the world’s leading astrophysicists, because data keeps pouring in to vet even the most radical theories. And the dominant mysteries are profound. She observes that “The vast majority of stuff in the universe—both dark matter and dark energy, which dominate the content and fate of the universe—is unknown.“ The universe’s greatest exotica are the focus of her research—dark matter, dark energy, and black holes. She is an expert, for example, in the complex behavior and gravitational lensing of galaxy clusters, where arrays of 1,000 galaxies are 95% dark matter. Her theory of the “direct” formation of supermassive black holes may explain the profound mystery of quasars. Priyamvada Natarajan is a professor in the Departments of Astronomy and Physics at Yale University and at the Dark Cosmology Center, Niels Bohr Institute, University of Copenhagen, Denmark. She is an active proponent for the public understanding and study of science.

Albert Einstein’s quip that “God does not play dice with the universe,” was about quantum physics, not a statement of faith. But he did ponder the relationship between science and religion and his sense of “the order deeply hidden behind everything.” With guests Freeman Dyson and Paul Davies we explore Einstein’s wisdom on mystery, eternity, and the mind of God.
