The Black Hole Light, by Mark Champkins, presented to Stephen Hawking on his 70th birthday by the Science Museum, in 2012. Cylindrical black stand holding a spiral-shaped neon light.

This illuminated scupture was the 70th birthday present to Stephen Hawking by the Science Museum. It was authored by the then inventor-in-residence Mark Champkins. The sculpture represents the trajectory of light as it falls into a black hole. Black Hole Light remained on display in Stephen's office from 2012 onwards.

Distributed around Stephen Hawking's Office are a selection of items with layers of scientific significance easily missed by the untrained eye. These are toys and gifts that have the closest connection to Stephen's theoretical work: research he was particularly proud of, and which also provided an easy way to illustrate difficult aspects of his theories to visitors.
