 These sorts of things are incredibly interesting. Technology is not advanced enough. We can build telescopes that are big enough, precise enough. We can do two things at the same time. They are big enough to observe objects that are extremely thin because they are 13 billion light years away. You must hear this all the time, but for me it really is one of the most exciting moments for me to be able to come and visit here. All the people who are not scientists who come here, the transformation in them, they will never be the same again. One of the things that I did was I funded science centres. And one of our science centres in Edinburgh has a 3D cinema and they show a film called We Are Astronomers and it's all about the VLT.
