Especially in light of the #EndSARS movement, a lot of politicians in Nigeria have expressed their belief in a need for social media regulation, with one man going as far as filing a lawsuit to stop Twitter from operating in the country. But what's Nigeria's Social Media Bill all about, and why are activists and social media users calling to #EndSocialMediaBill?

Cosmology is the one field in which researchers can—literally—witness the past. The cosmic background radiation, ancient light streaming toward us since the Big Bang, provides a pristine window onto the birth and evolution of the universe. Already, the radiation has been key to confirming an early explosive expansion of space, determining the geometric shape of the universe and identifying seeds that resulted in galaxies. Now, the cosmic background radiation is poised to reveal when the first stars formed, what happened in the fraction of a second after the Big Bang, and the answers to a host of other bold questions about the cosmos. Join Nobel Laureate John Mather and other leading scientists who are leading the way.

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.

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.
