The Bedroom Window
The bedroom opens onto a lanai (patio) with a panoramic view of the bay. Houston saw a lovely full Moon over the bay last night. The human-made moons of ISS and Discovery also passed overhead. In Houston people are still working hard to reach the Moon. Nights like this are made for contemplating the Moon.
The Lunar Laser Ranging Experiment measures the Moon's distance at 384,402 km. LLRE also reports the Moon receding at 3.82 cm/yr, anomolously high. If the Moon were gaining angular momentum at this rate it would have coincided with Earth only 1.5 billion years ago.
Geology and paleontology can measure more precisely how the lunar orbit has changed, reporting only about 2.8 cm/yr. This figure can be measured precisely. If the speed of light slows according to GM=tc^3, the time for light signals to return will increase each year. The Moon would appear to recede an extra .935 cm/yr as seen by LLRE. The lunar orbit anomaly is precisely accounted for.
One day the world that wonders at the sky will look up and see light slowing down. In the meantime, looking at the Moon is still a pleasure.
