Beyond the Darkness

   2001    Science
Thirty years ago, scientists first realized that some unknown dark substance was affecting the way galaxies moved. Today, they think there must be five times as much dark matter as regular matter out there. But they have no idea what it is - onl that it's not made of atoms, or any other matter we are familiar with. And Dark Matter is not the only strange substance in the Universe - a newly discovered force, called Dark Energy, seems to be pushing the very fabric of the cosmos apart.

Dancing in the Dark

   2015    Science
Scientists genuinely don't know what most of our universe is made of. The atoms we're made from only make up four per cent. The rest is dark matter and dark energy (for 'dark', read 'don't know'). The Large Hadron Collider at CERN has been upgraded. When it's switched on in March 2015, its collisions will have twice the energy they did before. The hope is that scientists will discover the identity of dark matter in the debris. The stakes are high - because if dark matter fails to show itself, it might mean that physics itself needs a rethink.

Dark Matter and Dark Energy

   2008    Science
Scientists have no idea what it is, but Dark Matter and Dark Energy make up 96% of the Universe. Dark Matter is everywhere. It passes through everything we know on earth at billions of particles every second, yet no one has ever gotten a direct detection of this mysterious dark substance. An even more bewildering force is Dark Energy, which is rapidly pushing apart our Universe. Discovered only ten years ago, scientists are struggling to comprehend its unusual characteristics and answer the ultimate question; what is the fate of our Universe? Using cutting-edge computer graphics watch as the universe is brought down to earth.

Death Of The Universe

   2008    Science
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.

Exploring The Universe

   2020    Science
This remarkable science-history series investigates the blistering pace of human endeavour in space exploration, computing, energy, resources, Earth science and our understanding of the evolution of life itself. Across the last 50 years, humans have set a blistering pace and scientific discovery. We've crossed the boundaries of our solar system, made machines that can learn harnessed the power of the sun and built life from scratch. It's a period like no other in history, where human endeavour is changing everything: this is The Great Acceleration. As we race toward the future, we must examine the journey.
In the first episode, Dr Shalin Naik explores the ambitious space shuttle mission that began in the '70s plus the future colonization of Mars. Over the past 50 years, space has become central to everything, from communications to entertainment to climate modelling. And as private enterprise enters space exploration, our understanding of the universe will only continue to expand. We will know if we can survive on other objects - the moon, maybe Mars, maybe even some of the moons of Jupiter and Saturn. Deep space is the last and infinite frontier. That's what we do as human beings. We explore, we learn, we make discoveries, from the moment we're born to the moment we die.
