The centre of our galaxy is home to an invisible monster of unimaginable power – a supermassive black hole named Sagittarius A star, with four million times the mass of the Sun. Recent astronomical breakthroughs have confirmed not only that black holes like Sagittarius A star exist, but that these bizarre invisible objects may be the ultimate galactic protagonists. Stunning CGI takes us back to witness the fiery origins of our galaxy’s black hole 13.6 billion years ago, when the early universe was home to colossal blue stars, and when they ran out of fuel, they collapsed under their own enormous mass, crushing down into an object so small and so dense it punched a hole in the fabric of the universe. Over billions of years, Sagittarius A star feasted on nearby gas, stars, and through cataclysmic mergers with other black holes. A breakthrough discovery by Nasa’s Fermi gamma-ray telescope has shown that our black hole had the power to sculpt the entire galaxy, creating vast bubbles of gas above and below our galaxy and even protecting stars systems as ours. In a mind-bending conclusion, Brian Cox reveals how our modern understanding of black holes is challenging our concepts of reality to the breaking point. In trying to understand the fate of objects that fall into Sagittarius A star, scientists have come to a stunning conclusion: space and time, concepts so foundational to how we experience the world around us, are not as fundamental as we once thought.
Nathan stages a ninth birthday party for Adam, but faces a problem when Remy, one of the child actors who played Adam at age six, becomes attached to Nathan, calling him 'daddy' even after his scenes are over. Remy's mother explains that her son might have trouble understanding the difference between acting and reality. To discover what went wrong, Nathan repeats Remy's scenes with different actors including Liam (a nine-year-old Adam actor), an adult actor, and a mannequin. He then explores what might have happened if Angela had stayed with him and meets with the real Angela, who urges him to forgive himself, as her religious beliefs state. In an attempt to truly understand the connection between parent and child, Nathan stages a new scenario in which he is Remy's mother Amber and Liam portrays Remy. They re-create the experience of appearing on The Rehearsal and becoming attached to 'pretend daddy' Nathan. After coming to the emotional realization that they should not have done the show, Nathan as Amber seemingly breaks character and tells the fake Remy, 'I'm your daddy.'
What If we could talk to animals? For as long as we've shared our lives with pets, we've been seeking better ways to communicate with them. In Washington state, Alexis Devine and her sheepadoodle Bunny think they've found a way of making communication a reality. Alexis went further than most, with a set of communication buttons, each programmed with a pre-recorded word to help humans and animals speak the same language. She has 90 buttons with which to express herself and even seems to combine them into simple sentences. Bunny is paving the way in pet communication. The undisputed masters of verbal communication are our pet parrots. They have mastered the art of vocal expression. Some parrots have even learned to fool devices designed to recognize human voices.
Nathan Fielder returns with a daring new season that elevates the concept of constructed reality to extraordinary extremes. This season dives even deeper into ethically charged scenarios, where real people rehearse life-altering choices inside meticulously engineered simulations. As the line between performance and authenticity dissolves, the series confronts our deepest questions about control, identity, and the limits of preparation. Disturbing, brilliant, and darkly hilarious—it’s an experience like no other. The opening three episodes raise the stakes immediately. A father struggles to reveal a devastating truth to his son—but the rehearsal begins to unravel his own sense of self. A woman prepares for a proposal that may never arrive, as emotional tension distorts her reality. And in a startling turn, Fielder inserts himself into the most personal rehearsal yet, facing consequences he may no longer be able to manage. With emotional weight, narrative twists, and biting satire, these episodes pull you in and don’t let go.
In Episodes 4–6, the journey takes an awe-inspiring turn through Norway’s dramatic fjords and along roads carved through towering cliffs. Ewan and Charley are captivated by centuries-old Viking churches and mysterious stone formations that whisper tales of the past. Their adventure shifts gears with a breathtaking detour to the Arctic archipelago of Svalbard, where melting glaciers and ghostly landscapes reveal the stark reality of a warming planet. As they venture deep into Lapland, isolation, snow-covered silence, and moments of wonder test their resolve and deepen their bond in unexpected ways.
