'We still don’t have the technology to verify Stephen Hawking's big ideas'

Maggie Aderin-Pocock on how the late physicist got people across the world talking and thinking about complex science

To my mind, Stephen Hawking's legacy is twofold: he was both a brilliant scientist who came up with some of the most revolutionary ideas of our time and a great communicator who managed to carry the world with him on a remarkable scientific journey. He got people across the world talking and thinking about complex science.

Some of his early work was linked to Einstein's theory of general relativity, which takes space and time and squashes them together to make what we call a spacetime. If you look at the universe this way you see all sorts of strange phenomena, including black holes. Before Stephen's work it was thought that nothing could escape a black hole, but his theoretical work led to the theory of Hawking radiation, which allows some radiation to leak from a black hole, enabling them to slowly decay and eventually evaporate.
