"For me, science fiction presents a vast array of questions," Connell said. "I probably spoil it for some people, but I can't help but look at this stuff and say 'why are they screaming in space?'. I always love seeing how things are represented in these movies because I like to point my physics brain at it and say 'hang on, is that right?'."

Transport

The exhibition starts with the juxtaposition of the Millennium Falcon, which can travel between galaxies effortlessly, and our own forms of space travel.

"We are not quite there yet," Connell said. "We can send things out, but people have been thinking about interstellar travel for a long time."

"These are models made by Industrial Light and Magic and some others are being proposed for how we might travel between the vast, vast, distances of interstellar space. How we will have enough fuel for it, in particular, is one of the big issues."
