For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter—atoms—accounts for only 4% of the weight of the cosmos. The rest—dark matter and dark energy—is invisible to our telescopes. But what really is this dark stuff? How do we know it’s there? And what does it do? From the formation of galaxies to the farthest reaches of space, it appears that darkness rules. Without dark matter and dark energy, the universe today and in the far future would be a completely different place. We were joined by leading researchers who smash together particles, dive into underground mines, and explore the edges of the known universe in search of clues to nature’s dark side.

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.

Bla Xit family, so you have woken up and realised that the reality you have been living is no longer the reality that you wish to live. You realise that you have been living in an open prison one where your liberties can be taken from you in a flash with your freedom too. So what is the solution, leave the prison as soon as you can get your Get out Of Jail card so you can proceed to go and collect your $200 as you p**** go. So you have purchased your land, what is your next move? You are going think about your home your ideal home and apply for your fencing and development permit. We want there to be a m**** exodus .

We want to thank Wode Maya our inspiration for starting us on our way and continuing to support us. Big up all of the Vloggers and Bloggers changing the narrative of Africa.

SABABU N. PLATA - Co-Founder of Afrikan World Info Systems

Hosted By: ShakaRa

Nana Amos Wilson is the Author of:
• The Developmental Psychology of the Black Child
• Awakening the Natural Genius of Black Children
• Blueprint for Black Power

He also established @Afrikan World Info Systems, a publishing company dedicated to knowledge production, specific to the needs of the Global Afrikan Community. Few, if any, were more prolific in providing a more scientific analysis of the plight of Black people, and putting forward tangible programmes. Shortly before the publishing of Blueprint for Black Power, Nana Wilson passed away - 14th January 1995. He was on the verge of developing a credit union and other institutions around the community businesses and organisations he was involved in.

Nana Amos Wilson laid a Blueprint. He did his work. Now we honour him the best way we know how - profiling those who are building on this illustrious legacy, engaging the Blueprint in thought and action.

On 15 August 2026, Abdourahmane Tchiani's revolutionary government signed a milestone agreement with Zimar Group to construct a 100,000-barrel-per-day refinery in Dosso.

This is part of the Nigerien government’s efforts to nationalize its resources, breaking the old cycle of exporting raw crude and importing refined products.

The project could allow Niger to capture more value from its hydrocarbon resources, as it is already doing with its other natural resources. It also promises to strengthen its energy security, and create a foundation for greater industrialization within the country and across the Sahelian alliance.

The majority of the world’s cocoa comes from West Africa, but less than 1% of the world’s chocolate is actually made there. In Ghana, chocolatiers are working to decolonize cocoa and bring delicious chocolate made locally from bean to bar to chocolate lovers worldwide.
