Testing Theoretical Ideas of Extra Dimensions

"Yet I exist in the hope that these memoirs, in some manner, I know not how, may find their way to the minds of humanity in Some Dimensionality, and may stir up a race of rebels who shall refuse to be confined to limited Dimensionality." from Flatland, by E. A. Abbott

Leaking Gravity May Explain Cosmic Puzzle
Gravity leakage should create minor deviations in the motion of planets and moons. Astronauts on the Apollo 11 mission installed mirrors on the lunar surface. By shooting lasers at the mirrors, a reflected beam can be monitored from Earth to measure tiny orbital fluctuations. Dvali said deviations in the Moon's path around Earth might reveal whether gravity is really leaking away.

You know for me, it's not enough just to swipe away ideas that have been expounded in a theoretical approach. Are we doing a disservice to the scientific process not to explore these potentials along the roads of theoretical ideas born and discharged to discussion?

Moonscience - Quakes, Shakes and Laser Beams

The second chief experiment in the Apollo 11 science package was the Laser Ranging Retro-Reflector, or LRRR. Roughly one foot square, the LRRR was a configuration of specialized mirrors that possessed the property of always reflecting light in the same direction as its source. The reflector was set up about 16 feet (5 meters) from the solar-powered seismic recorder. Resting on the lunar surface it resembled an oversize hotplate with a shiny top. It would be used to reflect laser beams sent from Earth in order to make very precise measurements of Earth-Moon distances. Although the moon is on average about 238,000 miles (385,000 kilometers) away from Earth, using this method, scientists can measure the Earth-moon distance to an accuracy of about 1 1/4 inches (3 centimeters).

I have listen to the Skeptic approach to resistance of something that has not been proven to exist, yet I had found things existing within our culture that said, yes it has not been proven, yet there is a track record of what GR has accomplished.

So should we let the resistance of fear insight distrust of the media, and have good science minds disrupt by instigating false reports like the one did by Alan Sokal in regards to quantum gravity? Nice way to treat those who move up to face the challenge of a theoretcial world that expects the same validation as any process?

I don't argue this, but I wonder then if we are given gravitational wave production such a vast monetary reward for such developements from what Einstein produced, then what justification was awarded such experimental processes, to say ,that the ideas of some I have been expounded in terms of those extra dimensions.

I thank Lubos Motl for speaking to the deconstruction process and what is being implied in particle reductionsism. What it has lead us too. He is advocating good technical structure for comprehension of thos esame dimensions and points out the theoretical spaces that this mathematics is involved in.

Q<->Q measure a reveals a much more dynamical world theoretcially that needs to be entertained.

Eric Adelberger and Blayne Heckel of the University of Washington in Seattle are no strangers to difficult gravity experiments. In the 1980s, they led one of a number of groups that investigated the existence of a postulated fifth force, which would show up as a gravitational anomaly over distances of up to 100 metres. Their findings helped to kill the idea.

Would you lesson the impact of Gaussian coordinates to any substantial view, because it makes use of those same theoretical spaces?

Dimopoulos has been strongly driven in his research by a desire to understand what lies beyond the standard model. His contributions have included work on grand unified theories of baryogenesis, which would provide an explanation of the origin of matter. Jointly with Stanford colleague Nima Arkani-Hamed and Gia Dvali of ICTP, Trieste, Italy, he has proposed an audacious solution to the problem of explaining the weakness of the gravitational force. The proposal invokes new large dimensions accessible to the graviton
