The History of Reality: What is real and is God behind it all?

Every civilisation that's ever existed has asked the same question: what's actually real? Plato made the point that it's more than we can see with our own eyes. Then came Newton, and reality became a clock with time. Then came Einstein, and time started to bend. Then came quantum mechanics — and reality gets stranger still! Two astrophysicists go back to the beginning of humanity to ask "what did humans even mean by "real", before anyone had the maths to check?" And is there a creator behind it all? GUESTS: Geraint Lewis, Professor of astrophysics at the University of Sydney, has spent his career hunting dark energy and dark matter — and doesn't believe in a God at the end of it. His new book is The Shortest History of Reality. His old friend and former student – now astrophysicist himself at Western Sydney University is Dr Luke Barnes, who works on the very same equations — and continues to believe it points to a creator.
