The gist of the article is that because the measured distance to the moon is slightly larger than a predicted value we might be seeing hubble expansion. Which is clearly not the same as saying hubble expansion has been observed. |

Which is clearly not the same as saying hubble expansion has been observed. Correct, it is known that Earth's shape has been changing due redistribution of mass since the last ice-age. The above article ignores this standard explanation for the discrepancy between the increase in the Moon's orbit and the slowing of Earth's rotation. -- Øystein Olsen, oystein.olsen_at_astro.uio.no, http://folk.uio.no/oeysteio Institute of Theoretical Astrophysics, http://www.astro.uio.no University of Oslo, Norway |

Nonsingular is finite density
Gravity doesn't require mass. Energy will do the trick. Learn GR. Moron. |

What is the gravitational strength of a photon? As a sideline Nick, in part of my ongoing study into you I notice you constantly talk about gravity and the phenomena associated with extremes of gravity (Black Holes etc). Do you understand enough physics to appreciate that while gravity may be a big player to humans, it is also the weakest force in the universe? |

Wrong Twake. Einstein says energy curves space.
That is his GR. Show me where I am wrong |

Dear Ralph Hertle:
"Ralph Hertle" wrote in message ... .... Any scientific work, however, that doesn't recognize the existence and function of hydrogen molecules in causing the the apparent Red Shift of light frequencies is of low grade. Possible explanations involving H2 must be considered and logically dealt with. They have been considered. There is plenty of hydrogen locally, more than for most of the path that ancient light travels. And we have tried to recreate such redshifting in the lab, but cannot do it with real matter. Absorption and non-specular scattering are problems in assuming that real matter is responsible for red shift. Fortunately for us the observations did not provide a scientific basis for measuring any change of the Earth-Luna distance. Actually, it did. Read the paper. David A. Smith |

LLR provides a recession measurement (and whatever distance factors are imbeded/ignored in the analysis). Deteminations of the Moon's period are based on observation/measurement. Does not "observation" involve measurement? The gist of the article is that because the measured distance to the moon is slightly larger than a predicted value we might be seeing hubble expansion. Which is clearly not the same as saying hubble expansion has been observed. I don't agree on "clearly not the same". David A. Smith |
