Information Preservation and Weather Forecasting for Black Holes

This was flagged to me by a friend and I very much enjoyed it.

“The collapse to form a black hole will in general be chaotic and the dual CFT on the boundary of ADS will be turbulent. Thus, like weather forecasting on Earth, information will effectively be lost, although there would be no loss of unitarity.”

In non-black hole related forecasts, but the outside my front window forecast today was for a brisk walk to buy bus tickets and a cup of steeped tea. The sky was nice and clear. There was a hint of rain alright but the entire weather system was utterly drowned out by a non-stop cacophony of sirens. Sirens were excessive this evening, I hope there’s nothing untoward happening in the city beyond the usual range of heart attacks, illness or accidents that befall us.
