We have written the evidence of our existence onto the surface of our planet. Our civilisation has become a beacon, that identifies our planet as home to life.

An explorer of the universe is sexier than a musician.

Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.

The aim of particle physics is to understand what everything’s made of, and how everything sticks together. By everything I mean me and you, the Earth, the Sun, the 100 billion suns in our galaxy and the 100 billion galaxies in the observable universe. Absolutely everything.

When we look out into space, we are looking into our own origins, because we are truly children of the stars.

The story of the universe finally comes to an end. For the first time in its life, the universe will be permanent and unchanging. Entropy finally stops increasing because the cosmos cannot get any more disordered. Nothing happens, and it keeps not happening, forever. It's what's known as the heat-death of the universe. An era when the cosmos will remain vast and cold and desolate for the rest of time the arrow of time has simply ceased to exist. It's an inescapable fact of the universe written into the fundamental laws of physics, the entire cosmos will die.

In science, there are no universal truths, just views of the world that have yet to be shown to be false.
