Ed Dwight could have been the only black astronaut in the 1960s – but politics got in the way. In 2024, at the age of 90, he finally got his chance to go into orbit.

Humanity has entered a new age of space tourism. For a minimum of $450,000 (£360,000), people with deep pockets can claim the title “astronaut” after a short sub-orbital flight to the edge of space and back and up to 10 minutes experiencing weightlessness above the Earth.

On these near-spaceflights, currently offered by Blue Origin and Virgin Galactic, there is usually one member of the crew whose name and story captures the headlines – and often a free ride.

Renowned researchers David Chalmers and Anil Seth join Brian Greene to explore how far science and philosophy have gone toward explaining the greatest of all mysteries, consciousness–and whether artificially intelligent systems may one day possess it.

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

What is the nature of quantum physics? Neil deGrasse Tyson and comedian Chuck Nice get quantum, exploring Schrodinger’s Cat, electrons, Hilbert Space, and the biggest ideas in the universe (in the smallest particles) with theoretical physicist Sean Carroll.

When did the idea of fields originate? Are fields even real or are they just mathematically convenient? We explore electrons, whether they are a field, and whether they exist at all. We also discuss the wave function, Hilbert Space, and what quantum mechanics really is. Do superpositions always exist?

What would happen if Planck’s Constant were macroscopic? Learn about entangling particles and the longest entanglement distances. If the particles are entangled why would the distance matter? Could we make an internet with quantum entanglement? We break down Schrodinger’s cat, its interpretations, and what the thought experiment really means. Do superpositions always exist?

Are there quantum manifestations in the macro-universe? We explore the microwave background, inflation, and how we discovered that atoms are mostly empty. Sean gives his latest takes on dark matter, dark energy, emergence, and free will. Plus, is dark energy really the cosmological constant?

Imagine a world where machines not only understand our words, but grasp the nuances of our emotions, anticipate our needs, and even surpass our own intelligence. This is the dream, and perhaps the near reality, of Artificial General Intelligence (AGI).

For many years, the idea of achieving AGI (Artificial General Intelligence) has only existed in the realm of science fiction. It’s been seen as a futuristic utopia where machines can seamlessly integrate into our lives. However, this perception is changing. Advances in AI technology are blurring the lines between fiction and reality, leading to both excitement and apprehension regarding its potential impact on society.

In this blog post, we’ll embark on a journey to explore the fascinating world of AGI. We’ll peek into the current state of AI and the significant innovations that are inching us toward AGI.

The discovery is the best candidate for a class of black holes astronomers have long believed to exist but have never found—intermediate-mass black holes formed in early stages of galaxy evolution.

Visible to the naked eye as a smudge in the night sky from Southern latitudes, Omega Centauri is a magnificent collection of 10 million stars. Viewed through a small telescope, it resembles other globular clusters —a densely packed spherical assembly of stars where the core is so congested that individual stars blur into one another.

However, recent research conducted by teams from the University of Utah and the Max Planck Institute for Astronomy has resolved a long-standing debate among astronomers by confirming that Omega Centauri harbors a central black hole. The black hole appears to be the missing link between its stellar and supermassive kin—stuck in an intermediate stage of evolution, it is considerably less massive than the colossal black holes that are typically found in the centers of galaxies. Omega Centauri seems to be the core of a small, separate galaxy whose evolution was cut short when it was swallowed by the Milky Way.

Dark matter could bring black holes together.

Dark matter that interacts with itself could extract significant momentum from a binary supermassive black hole system, causing the black holes to merge.

A gravitational-wave “hum” pervades the Universe.

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles.
