Infinity: The Science of Endless @WorldScienceFestival

World Science Festival "The infinite! No other question has ever moved so profoundly the spirit of man," said David Hilbert, one of the most influential mathematicians of the 19th century. A subject extensively studied by philosophers, mathematicians, and more recently, physicists and cosmologists, infinity still stands as an enigma of the intellectual world. Thinkers clash over questions such as: Does infinity exist? Can it be found in the physical world? What types of infinity are there? Through an interdisciplinary discussion with some of the world's leading thinkers, this program will delve into the many facets of infinity and address some of the deepest questions and controversies that mention of the infinite continues to inspire.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Carlo Rovelli and Brian Greene on Black Holes and White Holes

World Science Festival 2024-03-08 | Progress in the last decade has established that black holes are real, but what about their time-reversed cousins, white holes? Renowned physicist and author Carlo Rovelli joins Brian Greene to explore insights into these speculative astrophysical chimera.

This program is included in a 3-part series that explores the wondrous implications of gravity pushed to the extreme, tackling dark energy, black holes and white holes. Renowned researchers join Brian Greene to discuss a range of insights–from confirmed to highly speculative–that extend Einstein’s vision of reality and advance our understanding of fundamental physical laws.

Was the Big Bang the Beginning? Reimagining Time in a Cyclic Universe

World Science Festival 2023-12-22 | A universe that continually expands has long been the dominant cosmological framework. But a universe that undergoes cycles of expansion and contraction, perhaps for all time, has recently been analyzed mathematically, and its proponents claim that it provides a more convincing cosmological paradigm. Join leaders of this renegade approach as they make the case for a new kind of cosmology that reimagines time.

The New Golden Age of Space Exploration

World Science Festival 2023-06-30 | #space #NASA #JWST
In the next two decades, human beings will return to the moon, set foot on Mars, and launch telescopes capable of detecting extraterrestrial life. NASA’s outgoing head scientist Thomas Zurbuchen oversaw much of the planning for these projects, and space agencies around the world are pursuing similar goals collaboratively. Brian Greene is joined by Zurbuchen, Japan's Masaki Fujimoto, Europe's Kirsten MacDonnell and Australia's Aude Vignelles, as they reveal their plans for what promises to be a New Golden Age of Space Exploration.

Memory: The Hidden Pathways That Make Us Human

World Science Festival 2023-06-23 | Memory defines us. Memory is the basis of our sense of self. But how do the structures of the mind store memories? What changes do memories imprint on the brain? And what is the role of emotion in determining the quality of our memories? Brian Greene explores these and related questions with four top researchers--Veronica O’Keane, Tim Bredy, Gail Robinson, and Oliver Baumann—who unravel myriad mysteries of the human capacity for memory.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Rewriting the Story of Humankind

World Science Festival 2023-06-09 | What attributes set our species apart? Taming fire? Expressing artistically? Solving problems creatively? Recent discoveries that have already upended humankind’s origin story by expanding our family tree, are now challenging long-held assumptions about what makes us special. Paleoanthropologist Lee Berger is a leading figure in these breathtaking developments and he joins Brian Greene to discuss how new discoveries are now rewriting human history.

Brave New Prehistoric World

World Science Festival 2023-05-04 | Recent breakthroughs in dating ancient samples of DNA and human remains have led to a radical reassessment of human origins. At least ten other early human groups–some with the cognitive capacity to make art, jewelry and herbal medicines–occupied the planet at the same time as our ancestors, Homo Sapiens, and some of their genomes live within us today. Leading archeologists and paleoanthropologists join Brian Greene to discuss how these surprising new insights are transforming our understanding of early Humans.

Visual Illusions: Catching the Brain Creating Reality

World Science Festival 2023-02-02 | #briangreene #illusions #science
Visual illusions, from magic tricks to images that have sparked internet feuds, are providing scientists with evolving insight into the complex act of seeing. Illusions play with the way our eyes and our brains work together and help establish that what we “see” is shaped by everything from light and eye movement to the influence of expectation, memory and desire.

Neuroscientists Susana Martinez-Conde and Rodrigo Quian Quiroga and psychologist Emily Balcetis are among those using illusions to catch the brain in the act of interpreting and sometimes misinterpreting what the eye takes in. In conversation with Brian Greene, they discuss illusions involving everything from celebrity photos to police dash cam tapes to mind bending images that broke the internet.

The Dreaming Pen: From Lucid Dreams to Waking Art

World Science Festival 2022-11-30 | Meet Dave Green, a London-based artist who “creates” drawings in his lucid dreams, interacting with and depicting dream characters he meets along the way. From an early age, Dave (no relation to Brian Greene!) was a spontaneous lucid dreamer, employing this gift as a tool to deal with recurring nightmares. Now, as an adult, he’s shifted his focus to lucid dream art, exploring the intersection of imagination, perception, and reality during his nocturnal adventures.

This WSF Short is part of a wider conversation about dreaming featuring physicist and World Science Festival co-founder Brian Greene and researchers Deirdre Barrett, Ken Paller, and Antonio Zadra.

The Dreaming Mind: Waking the Mysteries of Sleep

World Science Festival 2022-11-17 | #briangreene #dream #science
Where do our dreams come from, why do we have them, and what do they mean? Can we harness them to foster creativity, solve problems, and prepare for the future? What’s happening in the brains of so-called lucid dreamers, and can new developments in this cutting-edge field of research help us unlock the mystery of consciousness itself? Researchers Deirdre Barrett, Ken Paller, and Antonio Zadra join Brian Greene for a discussion about the mystery and power of dreams and where our minds go after midnight.

Einstein and the Quantum: Entanglement and Emergence

World Science Festival 2022-03-31 | #BrianGreene #blackholes #AlbertEinstein #quantummechanics
With his General Theory of Relativity, Einstein illuminated the grand expanse of the cosmos, but he was also instrumental in developing quantum mechanics for describing the microworld. In Einstein’s day, these advances were considered unrelated but recent insights suggest that they may be secretly connected–significantly advancing our understanding of quantum threads that may stitch the fabric of spacetime. Leonard Susskind, Ana Alonso-Serrano and Mark Van Raamsdonk join Brian Greene to examine this newfound link and explore its implications for uniting the laws of the large and those of the small.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Things We’ve Never Seen: The James Webb Space Telescope Explores the Cosmos

World Science Festival 2021-12-23 | #BrianGreene #NASA #JWST #UnfoldTheUniverse
The powerful James Webb Space Telescope--the successor to the Hubble Space Telescope--promises insight into profound questions that have dogged philosophers and astronomers for millennia. What is the origin of the universe? How are stars and planets created? Is there life elsewhere in the universe? Brian Greene brings together four scientists who will use the Webb to investigate these very questions: John C. Mather, NASA’s lead scientist on the project and a Nobel Laureate; Natalie Batalha, NASA’s lead scientist on the Kepler Mission, which discovered the first rocky planets outside our solar system; Adam Riess, who earned a Nobel Prize for his revelations about the expansion rate of the universe; and Ewine van Dishoeck, a Kavli Laureate for her pioneering work in the field of astrochemistry.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Participants:
- John C. Mather
- Natalie Batalha
- Adam Riess
