LC > I am not suggesting eternal in the past; rather, that bubbles have some starting time, t=0 for a particular bubble, and since, like our bubble, they have been expanding for finite time, none cannot be infinite in spatial extent. They can't be flat and infinite in spatial extent. AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
