Trivia: Moon is Moving Away

Who ever imagined that the Moon is moving away from Earth? I never thought so until I watched the TV documentary on The History Channel! The Moon is moving away from Earth at the rate of 1 to 2 inches every year! Earths' "gravity" is losing grip of the Moon and would eventually stray off its' orbit and wander in space.
Scientists in the documentary attribute this to the speed of Earth rotating 360 degrees on its axis in only 24 hours while the Moon is a lot slower taking it a month to circle the earth. The speed of Earth is sort "throwing off" the moon from its orbit. It was also mentioned that the earths' oceans have a big role on this.
The scientists, however, gave their assurance not to worry. If I got it right, it will only happen after 50 Billion years. The sun will will even fizzle off earlier and that will be after 10 Billion years.
