Is Time Travel Possible? Stephen Hawking explores the world's favourite scientific 'what if?' He explores all the possibilities, warping the very fabric of time and space as he goes. From killing your grandfather to riding a black hole, we learn the pitfalls and the prospects for a technology that could quite literally, change everything.

Red Bull's Max Verstappen pulls off a string of victories. Lewis Hamilton of Mercedes struggles to keep pace. Later, an accident leads to controversy. We will see more Red Bull vs Mercedes, with a bit of Ferrari thrown in. Again Wolff and Horner engage in what appear to be pretty staged chats with their loved ones over the first meal of the day about the intensity of the championship fight but also pumpernickel.
Monaco plays out brilliantly for Red Bull and miserably for Mercedes, but several laps of Horner’s garden still look more exciting than that ’21 GP round the principality. Things all come to a head at the British GP, and we will all know how that ends. Cue more swearing and breakfast war-planning.

The true story of physicist J. Robert Oppenheimer's journey from driven and ambitious scientist to remorseful and tormented man struck hard by the gravity of what he had done. For Oppenheimer, the successful detonation of the first atom bomb validates years of tireless work. But in this moment of seeming triumph, Oppenheimer sees before him a destructive power of almost supernatural magnitude.
The films explores how one man's brilliance, hubris and relentless drive changed the nature of war forever.

(Click CC for subtitles) Ranjit, a farmer in India, takes on the fight of his life when he demands justice for his 13-year-old daughter, the victim of a brutal gang rape. His decision to support his daughter is virtually unheard of, and his journey unprecedented. Nominated for Best Documentary Award, the film has an undeniable and unshakable power. It is one of those documentaries where anyone who watches it won’t be the same person by the end as they were when it started.
To Kill a Tiger offers the viewer remarkable access to village life, not just in the modest home where Ranjit’s family make roti on an open fire, but in the fields where they herd goats and collect water from a pump. The camera finds quiet details, like Ranjit’s daughter carefully weaving ribbons into her hair. Women and men insist that the community, not the criminal court, should solve the issue with a forced marriage—to remove the ‘stain on her’. The men become increasingly hostile—to the family, and eventually to the film crew itself.

The determination of the German forces to keep on fighting in the face of defeat had disastrous consequences. After the Allied landings in the summer of 1944, the Wehrmacht was on the defensive on all fronts. It was clear to the German generals interned at Trent Park that Germany would soon lose the war. In mid-1944, Gerhard Graf von Schwerin chose to use common sense instead of blindly obeying Hitler's orders. He decided to surrender the city of Aachen to the US army to avoid bloodshed. Other commanders such as Field Marshal Ferdinand Schorner kept on pushing their soldiers to give their all. Despite being outnumbered by the Soviet forces, Schorner forced his soldiers to hold out in Sworbe, a 200 square kilometre peninsula on the coast of Estonia. Thousands of soldiers died. Yet Schorner's attitude and the urging by Hitler and Goebbels to hold out were accepted by a large number of young soldiers. By April 1944, the Ruhr pocket was completely surrounded, yet Field Marshal Model refused to surrender, so that 1.2 million German soldiers and a large number of Allied soldiers died between January and May 1945.

We’re going back to the moon. Plans are being made, hardware is being designed, built, and tested to return humans to the moon and beyond in a new era of American space exploration. This episode explores how we did it in the past, and how and why we will do it again. The moon is critical to future explorations: it will be where we learn to build sustainable colonies on other worlds.
