While scientists have previously theorised about a “Big Crunch” where the universe retracts back to its original size, the discovery of Dark Matter and Dark Energy has placed that hypothesis on the backburner. Some astronomers now believe that if Dark Matter offsets Dark Energy then as the universe slowly expands, stars will gradually fade, running out of fuel and leading to a dark, cold and lifeless universe. Others hypothesise a much more violent end where Dark Energy continues to expand the universe at a greater and greater speed. Stronger than gravity, Dark Energy would pull apart everything down to the fundamental particles – the universe’s very fibres. While the universe’s end may be 50 billion years away, great leaps in science will continue to alter how we believe the universe was formed – and how it will end.

Most planets we know of are so hellish, it seems impossible that anything could live. But it's amazing where life can take hold in the Earth. Astrobiologists look for simple single-celled microbes known as extremophiles in places as Danakil Depression, known in Ethiopia as 'The Gateway to Hell.'
In Episode 2, the fictional world is Janus, a planet in such a close orbit than its rotation is locked by the star's gravity and it always shows the same face to its sun. On one side of the planet, it's always daytime, a searing desert. On the other side, it's forever night, a frozen shadowland. Squeezed between the two, a sliver of perpetual twilight. Freezing meltwater flows from the cold side, carving canyons through the landscape. Deep in these canyons lives an extraordinary five-legged creature.

The sixth episode of the series narrates the fascinating story of the evolution and survival of life on our planet after the catastrophic event that marked the end of the era of dinosaurs, 66 million years ago. Through a visually stunning journey, we will see the impact of the meteorite and all its consequences in detail. We will also discover how the animals and plants that survived the mass extinction adapted, evolved, and diversified to fill the ecological niches left by the dinosaurs. From the first mammals and birds that emerged from the ashes to dominate the Earth, to the formation of complex ecosystems in the oceans and on land, the documentary offers a unique vision of the resilience and innovation of life on our planet.
With impressive imagery and exciting stories, it reveals how life, against all odds, thrived after one of the most devastating events in Earth's history. This documentary is a testament to the unbreakable strength of life and its ability to adapt and flourish even in the most adverse conditions.

Join us on an unforgettable voyage through one of the most desolate periods in human history as the rulers, conflicts, and cataclysmic societal breakdown of Early Middle Ages are brought to light. At its height in the second century A.D., the Roman Empire was the beacon of learning, trade, power and prosperity in the western world. But the once-powerful Rome--rotten to the core by the fifth century--lay open to barbarian warriors who came in wave after wave of invasion, slaughtering, stealing, and ultimately, settling. As chaos replaced culture, Europe was beset by famine, plague, persecutions, and a state of war that was so persistent it was only rarely interrupted by peace.
The documentary profiles those who battled to shape the future, from the warlords whose armies threatened to case the demise of European society, like Alaric, Charles the Hammer, and Clovis; to the men and women who valiantly tended the flames of justice, knowledge, and innovation including Charlemagne, St. Benedict, Empress Theodora, and other brave souls who fought for peace and enlightenment. It was in the shadows of this turbulent millennium that the seeds of modern civilization were sown.
