Measuring The Distance From Earth To Moon

lewiz writes: "Tom Murphy at UW is attempting to measure the distance between the Earth and The Moon to the nearest millimetre according to this BBC News article. 'His tape measure will be a giant telescope at Apache Point in New Mexico. Retroreflectors left on the surface of the Moon by various space missions, including the Apollo 11 lunar landing, will also come in handy.'"

    ...Check the Odometer on the Apollo 11 capsule.

    Bzzztt. The speed that the moon receeds wasn't measured directly, especially by doppler shift of all things. It was calculated from the kinetic energy gained by the moon from the Earth from tidal forces.

    - The moon's orbit about the Earth is a 100-page equation, not a constant.

    - The Earth's rotation is not circular (it "sloshes").

    - The Earth's shape is not constant.

    - The Earth's mass is not constant, so the general relativistic field in which the moon orbits is not constant.

    - Okay, so we know where that telescope is relative to the moon. Now where is it relative to my house? To Washington? To Wendy's?

    - Isn't this just an attempt by the Bush White House to wag the dog to distract attention from the fistfight the President and Vice President had during the game Sunday?

  4. Reflectors on the moon? It's a lie !!! by bani · · Score: 5, Funny

    ... according to Bart Sibrel :D

    To sum up: "we never went to the moon, hence there are no reflectors on the moon."

    Moderators: Put down the crack pipe and the mouse. Step away from the keyboard. Take a DEEP BREATH and READ. This is not a troll. I repeat. This is not a troll.

    No, I don't believe the "moon hoax" loonies. Anyone with an above-kindergarten education can easily refute the "moon hoax" loonies claims.
