Wherever you are on Earth, there is more life present than in the rest of the known universe.

The main battle is to make people realise that doubt is important. Doubt is good. The 'don't know' answer sometimes is the box you should tick, and it's about not being scared about that fact. Even the greatest minds don't know everything.

I have a problem with telling jokes about physics. Quite often the audience have no idea what you are talking about and, to be honest, I don't know what I'm talking about either.

There can be a science to joke writing, there are certainly rules and patterns that can be followed, but I think most of the best comedy goes beyond the rules.

I think the thing is with a movie that has this much science fiction in it; you need characters who are more science fact, if you know what I mean, than they are human.

However far modern science and techniques have fallen short of their inherent possibilities, they have taught mankind at least one lesson; nothing is impossible.

Unfortunately, things are different in climate science because the arguments have become heavily politicised. To say that the dogmas are wrong has become politically incorrect.

If Margaret Thatcher took climate change seriously and believed that we should take action to reduce global greenhouse emissions, then taking action and supporting and accepting the science can hardly be the mark of incipient Bolshevism.
