Top scientist asks: is life all just a dream?
Jonathan Leake, Science Editor
DEEP THOUGHT, the supercomputer created by novelist Douglas Adams, got there first, but now the astronomer royal has caught up. Professor Sir Martin Rees is to suggest that “life, the universe and everything” may be no more than a giant computer simulation with humans reduced to bits of software.
Rees, Royal Society professor of astronomy at Cambridge University, will say that it is now possible to conceive of computers so powerful that they could build an entire virtual universe.
The possibility that what we see around us may not actually exist has been raised by philosophers many times dating back to the ancient Greeks and appears repeatedly in science fiction.
However, many scientists have always been dismissive, saying the universe was far too complex and consistent to be a simulation.

In a television documentary, What We Still Don’t Know, to be screened on Channel 4 next month, he will say: “Over a few decades, computers have evolved from being able to simulate only very simple patterns to being able to create virtual worlds with a lot of detail.
“If that trend were to continue, then we can imagine computers which will be able to simulate worlds perhaps even as complicated as the one we think we’re living in.
“This raises the philosophical question: could we ourselves be in such a simulation and could what we think is the universe be some sort of vault of heaven rather than the real thing. In a sense we could be ourselves the creations within this simulation.” ...cont'd
