What is String Theory? @WorldScienceFestival

World Science Festival Brian Greene explains the basic idea of String Theory in under 3 minutes. Thirty-five years ago string theory took physics by storm, promising the coveted unified theory of nature’s forces that Einstein valiantly sought but never found. In the intervening decades, string theory has brought a collection of mind-boggling possibilities into the lexicon of mainstream thinking—extra dimensions of space, holographic worlds, and multiple universes. Some researchers view these developments as symptoms of string theory having lost its way. Others argue that string theory, although very much still a work in progress, is revealing stunning new qualities of reality. Join leading minds in theoretical physics for a whirlwind ride through the twists and turns of string theory—its past, its future, and what it tells us about the search for the universe’s final theory.

World Science Festival 2024-03-08 | Gravitational Echoes: Just as sound waves can echo off a distant rockface, light waves can echo off of black holes. Renowned researchers Erin Kara and Shep Doeleman join Brian Greene to explore the exotic physics that rules all that happens near the edge of a black hole.

BEYOND EINSTEIN is 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.

Beyond Einstein: Gravitational Rainbows

World Science Festival 2024-03-08 | BEYOND EINSTEIN is a 3-part series exploring 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.

Gravitational Rainbows: Much as a gentle mist can split light waves into beautiful rainbows, dark energy may split gravitational waves into deeply revealing gravitational rainbows. Leading researcher Claudia de Rham joins Brian Greene to explore this compelling possibility.

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.

Brian Greene talks with Neuroscientists Takao Hensch, John Krakauer and Entrepreneur Brett Wingeier about their experiments using brain plasticity to heal illness, improve cognitive and athletic performance. They also raise warning flags about the race to build a more perfect human.

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.

Watch the full conversation “The Dreaming Mind: Waking the Mysteries of Sleep” here:
