Is it possible that the universe expansion speeding up is caused by gravitational pull of other universes?
The idea that a basic force not yet discovered is pushing the universe outward at an ever-increasing rate seems unlikely to me as I would think that force would have been detected and would manifest itself in other ways. It would also help to explain the missing dark matter, as that could be extra-universal matter.

When did a stigma become attached to drunkenness?
I was reading about the [Gin Craze](_URL_0_) on Wikipedia where the government promoted production of gin, and the people of England were on average drinking 2.2 gallons of gin a year in 1743. It also mentions elsewhere that there was little stigma attached to drunkenness previous to this.
