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

Climate change: Don't undermine the science just because you don't like the economics

Science is too important not to be a part of popular culture.

If people don’t have an understanding of what science is and what scientists do, then they can tend to think that global warming, for example, is just a matter of opinion.

For me, Woody Allen's 'Manhattan' defines New York. Both New York and Manhattan Island should be in black in white! I always hear the soundtrack of Gershwin in my head every time I go over the Queensboro Bridge, or come in from JFK because of it!

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.

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.
