The neutrino is among the cagiest of particles, a subatomic wisp so ephemeral it could pass through light years of lead with more ease than a hot knife through butter. Despite its extraordinary abundance in the universe—billions pass through your body every second—this ghostly particle is notoriously difficult to trap, inspiring some of the most sophisticated detectors in science just to study it. A closer look could change everything. The elusive neutrino holds clues to some of the most profound questions in particle physics: What happened in the briefest moments after the Big Bang? Why does the universe contain more matter than antimatter? Join leading researchers as they chase neutrinos and other elusive particles in search of nature’s fundamental order.

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

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

Can neutrinos move faster than light? 1:18:46

What happened to all of the universe's antimatter? Can a particle be its own anti-particle? And how do you build an experiment to find out? In this program, particle physicists reveal their hunt for a neutrino event so rare, it happens to a single atom at most once every 10,000,000,000,000,000,000,000,000 years: far longer than the current age of the universe. If they find it, it could explain no less than the existence of our matter-filled universe.

SEMINAR TITLE: “Black People in the Biblical Lands of Kush andEgypt & Their Contributions to the World.”

6) Ancient African contributions in Architecture and a practical application of the practical knowledge learned about classical African civilizations

Background:Presenter is Professor Manu Ampim:Prof. Manu Ampim is the director of Advancing The Research and is a noted historian and scholar specializing in Africana Studies. He has conducted primary (first-hand) research in nearly two dozen countries over the past 30 years, and is the author of numerous scholarly articles and several books, including his latest work, A History of African Civilizations (2019). Prof. Ampim is also a tenured professor at Contra Costa College (San Pablo, CA) and Chair of the History, Anthropology, and Geography Department. In addition, he has facilitated various workshops throughout North America, and has worked with several renowned scholars.Week 1 Resources document that Professor Ampim compiled to help support the attendees of the class last week and to further answer the main questions that were raised. I noted in the Bibliography that my book, A History of African Civilizations ($24.95), is the most relevant source for the 6-week seminar and can be ordered below.https://advancingtheresearch.org/prod...

J Richard Gott leads a journey through the history of our understanding of the Universe’s structure, and explains the ‘cosmic web’: the idea that our Universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies.

J. Richard Gott's book "The Cosmic Web: Mysterious Architecture of the Universe" is available for purchase now - https://geni.us/EtIx

J Richard Gott was among the first cosmologists to propose that the structure of our Universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies – a magnificent structure now called the 'cosmic web'. In this talk he shows how ambitious telescope surveys such as the Sloan Digital Sky Survey are transforming our understanding of the cosmos, and how the cosmic web holds vital clues to the origins of the universe and the next trillion years that lie ahead.

J Richard Gott is Emeritus Professor of Astrophysical Sciences at Princeton University and is noted for his contributions to cosmology and general relativity.
