Rees: Think big, like Einstein

Today's scientists need to broaden their horizons to meet the scientific and intellectual challenges of the future, writes Martin Rees in his Telegraph article, Think big, like Einstein.

But what's not yet part of common culture is the concept that the vistas stretching ahead are even longer – the future allows time, potentially, for further evolution as dramatic as what's led from the very first life to humans. It will not be humans who witness the demise of the Sun six billion years hence: it will be entities as different from us as we are from bacteria.
