We used to think that Earth was at the centre of the universe, but now we know we're not even at the centre of our own galaxy. Countless wonders exist between where earth is situated and the massive black hole at the galactic centre of our galaxy. Within the Milky Way can be found the debris of old, dying stars fuelling the birth of new stars and at the galactic centre hypervelocity stars get catapulted clear beyond the Milky Way's outer rim at unimaginable speeds. Come along for a guided tour of 100,000 light-year-wide family of stars and stellar phenomena we call The Milky Way.

Foo Fighters prepare to record at the Austin City Limits Studio, with blues guitarist Gary Clark, Jr. In this episode is examined the roots of Austin's music scene, with interviews featuring Billy Gibbons from ZZ Top, and Roky Erickson from 13th Floor Elevators, who is considered one of the American fathers of psychedelic rock. Dave also chats with Terry Lickona, the executive producer of Austin City Limits. The song 'What Did I Do? / God As My Witness' is recorded during this chapter.

The documentary, an own production, immerses the viewer in a journey that blends science and philosophy, questioning the nature of time and unveiling a 4-dimensional universe, where space and time are integrated. We are invited to consider a universe in which past, present, and future coexist, suggesting that our linear perception of time might be more of a mental construction than a physical reality. The narrative progresses by exploring how quantum particles exist in states of probability until they are observed, at which point they acquire defined properties. Then, the provocative hypothesis is presented that observation also fixes the temporal dimension of the particles.
The sensation of the flow of time and the distinction between past, present, and future are introduced as mental constructions, arising from the human brain's limited capacity to process the complexity of reality. It is then proposed that the mind, by observing itself, fixes itself in the temporal dimension, thus creating the illusion of the present. Finally, the impact of these theories on free will is discussed.
This documentary challenges viewers to look beyond their everyday perceptions and consider the possibility that reality is much more complex and fascinating than our immediate experiences suggest. It is an invitation to explore the limits of science, philosophy, and the mind itself in search of answers to some of the deepest questions of existence.

Feast your eyes on a reconstruction of the mega-city and its amazing buildings. Alexandria, built in the middle of rancid marshland, had become in less than a century, the greatest city of the Mediterranean. An ideal position at the crossroads of east and west, and one that brought her great riches. Huge, modern, gleaming white and cosmopolitan, like no other in antiquity, it created its own identity.
While the beauty of its planning, its great arteries, its temples and its ports would be equalled only by its openness to the rest of the world. And the monumental achievements of its sovereigns, still shrouded in mystery, we'll never cease to fire our imagination for millennia to come.

The meteoric rise of renewable energy has consequences for our electricity supply. While coal and gas fired power stations can generate electricity whenever you need it, renewables are intermittent by nature. So we need a backup plan for when the wind stops or the sun goes down.
All over the world, engineers and scientists are racing to solve one key problem; how to safely and efficiently store electricity at a huge scale but at a low cost. The quest is producing some truly remarkable ideas and this episode details three of them.
