Stephen Hawking’s explosive new theory
By Roger Highfield, Science Editor
…”Their idea is therefore to start with the conditions we observe today - like the fact that at large scales one does not need to adopt quantum lore to explain how the universe (it behaves classically, as scientists say) - and work backwards in time to determine what the initial conditions might have looked like.
In this way, they argue the universe did not have just one unique beginning and history but a multitude of different ones and that it has experienced them all.
The new theory is also attractive because it fits in with string theory - the most popular candidate for a “theory of everything.”
String theory allows the existence of an” unimaginable multitude of different types of universes in addition to our own,” but it does not provide a selection criterion among these and hence no explanation for why our universe is, the way it is”, says Prof Hertog.
“For this, one needs a theory of the wave function of the universe.”
And now the world of cosmology has one. The next step is to find specific predictions that can be put to the test, to validate this new view of how the cosmos came into being”.
- Poor creationists. Soon enough their god will not be able to hide in big bang cosmology.
