everything is fundamentally perfect


The laws of physics

appear “fine tuned” for our existence.

Even slight deviations in the laws would result

in a universe devoid of stars and life. If, for instance,

the force of gravity were just a few per cent weaker it could

not squeeze and heat the matter inside stars to the millions of

degrees necessary to trigger sunlight-generating nuclear reactions.

If gravity were only a few per cent stronger, however, it would

heat up stars, causing them to consume their fuel faster.

They would not exist for the billions of years

needed for evolution to produce

intelligence. This kind

of fine tuning is
