The study authors suggest this might be part of an approximately 70-year cycle where the core speeds up and slows down relative to the rest of the planet. by shiruken How does this play with conservation of angular momentum? If the core slows down or reverses, shouldn't something else speed up or slow down in the opposite direction? Permalink 1
