What on Earth is Wrong with Gravity

There's a force of nature that's baffled the most famous names in the history of science.
Galileo laid the foundations but didn't get any further.
Newton thought it was the work of God.
And even Einstein, Albert Einstein failed to solve it.
It 's a mystery that lies at the heart of everything...
..from the Big Bang and the beginning of time...
..to the existence of life on Earth.
From strange distortions in the cosmos to the smallest stuff of matter.
It 's a puzzle that's led to the most abusive slanging matches in modern science.

But I think that within my lifetime we may succeed where many of the greatest brains in history failed, and finally solve one of the biggest mysteries of the universe.
I'm Brian Cox, particle physicist.
I have one of the best jobs in the world.
I have to find out what are the fundamental building blocks of the universe.
How do they stick together, how do they work and, with a bit of luck, find out why they're there at all.
I've spent the last ten years looking at the smallest stuff in the universe.
But I'm interested in the biggest questions you could possibly ask.
Why do I exist?
Why do you exist?
Why is the Earth the way it is?
Why is the universe the way it is?
Why is the universe built in a way that life can exist at all?
At the root of all these questions lies a force of nature that surrounds us, penetrates us and binds the galaxy together.
