Rama Set, you don't have any idea what you're talking about. It has been proven you don't know what you're talking about. You are a liar and have been obsessively commenting on my thread for days despite not having anything meaningful to add to the discussion, but only lies and obfuscation. You show no signs of being able to engage in intelligent discussion because you constantly change your story, have no sources at all to back anything you say, other than telling lies that some un-named entity elsewhere on the Internet, who you say is a UK astronomer, somehow agrees with you - despite your now admitting that the basis for your original "objections", which said astronomer corroborated, were actually completely without merit.
Anyone with a working brain who reads your "contributions" to this thread will come to the same conclusion.
Sorry, but I cannot "argue" with someone whose demeanor is that of an unresponsive troll who cannot engage in logical conversation.
At this point I'm no longer reading your comments and will only reiterate the following facts whenever you reply: (note: this is a clear signal that you, "Rama Set", need to stop obsessing over and posting replies to this thread)
ACCORDING TO HELIOCENTRIC THEORY and the LUNAR LASER RANGING EXPERIMENT:
1. Earth is orbiting around the sun at ~30 km per second.
https://www.google.com/#q=earth+orbital+velocity2. Laser is aimed toward the lunar retro-reflector
at an offset to account for motion during the time it takes light to traverse the distance.
http://physics.ucsd.edu/~tmurphy/apollo/0710.0890v2.pdf3. Light takes ~1.25 seconds to traverse the distance between the laser on earth and the retro-reflector on the moon.
http://physics.ucsd.edu/~tmurphy/apollo/0710.0890v2.pdf4. The retro-reflector is composed of corner cube prisms that return light back in exactly the same direction from which it came.
http://physics.ucsd.edu/~tmurphy/apollo/lrrr.htmlFrom these facts the unavoidable conclusion is that the laser light returned by the retro-reflector ~2.5 seconds later will be centered on where the laser
was when the light was emitted -
BUT this location will be ~75 km away from the current position of the laser/detector apparatus because the earth will have moved 2.5 * 30 km in the time it takes light to make the round-trip. Because the return beam is claimed to have a 10 km radius the telescope and detector will be at least 65 km outside of the area the light returns to, and, hence, be impossible for the experiment to ever work.
