When Einstein conducts one of his thought experiments, he is modelling
in his mind the universe as he conceives it. He imagines that he is
travelling on a beam of light. He is holding up a mirror twelve inches
from his face. What happens? he asks himself. There is nothing to be
seen in the mirror. At 186,000 miles per second, nothing can overtake
me; nothing travels faster. So, if my image cannot travel faster than
the speed of light, then it can never arrive at the surface of the
mirror. That’s the thought experiment, based upon the Einsteinian model.
And if I now create a phrase to encapsulate it and say ‘travelling at
the speed of light is an endless stare into an empty mirror’ I have
created my metaphor. One thing – the speed of light – is another – a
stare into an empty mirror; each belongs to a different intellectual
genus.
