Time Travel: It Is More Than Science Fiction by Experience ANU published on 2020-06-29T00:25:05Z The concept of time travel is very familiar from science fiction stories. Is this concept coherent? Perhaps surprisingly, the laws of physics (as currently understood) do not rule out time travel. Indeed, several physical mechanisms for travel to the past have been proposed over the last few decades. In this interview, the implications for both physical science and our view of reality (given the possibility of time travel to the past) are explained. Interview of Dr Peter Riggs, Dept. of Quantum Science, ANU. Interviewed by Maggie Riggs.
