WEST LAFAYETTE, Ind., May 22 (UPI) -- Earth is pushing the moon away faster now than it has for most of the past 50 million years, mostly a result of tides, a U.S. researcher says.
Matthew Huber of Purdue University says his models of the influence of tides on the moon's orbit help solve a longstanding mystery concerning the moon's age, NewScientists.com reported Wednesday.
