What on Earth is wrong with gravity?
Dr Brian Cox wants to know why the Universe is built the way it is. He believes the answers lie in the force of gravity. But Newton thought gravity was powered by God, and even Einstein failed to completely solve it.

Wonders of the Universe
Professor Brian Cox reveals how the most fundamental scientific principles and laws explain not only the story of the universe, but the story of us all.
1. “Destiny”
In the first episode, Cox considers the nature of time. He explores the cycles of time that define the lives of humans on the earth, and compares them to the cycles of time on a cosmic scale. Cox also discusses the 2nd Law of Thermodynamics and its effect on time, and the Heat Death theory concerning the end of the universe.
2. “Stardust”
In this episode, Cox discusses the elements of which all living things, including humans, are made. He explains how these elements are related to the life cycles of the stars and the recycling of matter in the Universe.
3. “Falling”
This episode documents how gravity has an effect across the Universe, and how the relatively weak force creates an orbit. We also see how a neutron star’s gravity works. Finally, there is a look back at how research on gravity has enabled us to better understand the cosmos.
4. “Messengers”
The final episode shows how the unique properties of light provide an insight into the origins and development of mankind and the Universe. We also see how the speed of light is both a measure of time and distance. This leads on to pinpoint one of the early events in the evolution of life.
