Wave On a Pond
Drop a rock into the middle of a pond and this action takes place.
Hitting the water that is non-compressible the water comes up the sides of the rock and is pushed away in all directions. It creates a circular wave that is moving up and down,and the circle gets bigger and bigger as it moves towards the shore. Bigger makes the wave lose energy,much like big light waves(radio) have far less energy as gamma rays. The pond wave comes to shore as a tiny ripple,and rubbing against the sandy shore bottom its energy is converted to heat. The pond wave obeys the square law,and reality is no matter how big the pond is the wave will never lose all its energy. It will reach the shore. Like a light wave can go to infinity Bert |

Good Morning Double-A You are up early. I shall think about it. My
point of the post is like distance dilutes a water wave's energy this also relates to the wave energy of light. Bert. |

Best to keep in mind pond waves,and space waves only relate to each
other in our minds. Reality is they have great differences Bert |

Water waves are transverse like light waves, but as you say, water waves ride the sort of two- dimensional surface of a body of water. Light waves OTOH are emanated from a body in ALL directions in three dimensions. You on the West coast of the US, and Bert on the East coast, can watch the same star at the same time because of this. And that star might be being watched by somebody in a star system on the other side of that star. So accepting the nature of spacetime to be a high-grade energy that is modulated (waved) by this starlight, i wonder how precisely to picture it. It seems to be as hard to picture this as it is to picture the rubber mat/bowling ball analogy of curved space. We usually see this depicted with only one mat. Yet we know deep down that there must be infinite "mats" around every body. So how would *you* picture the light signal as it vibrates the SPED? happy days and... starry starry nights! -- Tender is my love for thee Oh star so close at hand, Warming those so dear to me As we play on the sand...

I don't know the exact pircture, but photons don't lose amplitude as they go like a pond wave does. They get more spread out and farther apart. So the number of photons from the Sun hitting your eye at 93 million miles from the Sun would be 1/4 as many as would be hitting you eye at 46.5 million miles from the Sun. That is because the photons at 46.5 mm are spread over a sphere with only 1/4 the surface of a sphere with twice the radius at 93 mm. That is why the intensity of light diminishes with the inverse square of the distance. Double-A |

Double-A & Painius Waves in a pond need a medium(water's surface) Light
waves need no medium. lots of other tricky stuff that don't make them all that relative Bert |

His term 'nether' is synonymous with our 'SPED'. He pictures the electron as a single 'bathtub drain' standing-wave vortex (where Wolter pictured it as `two` mirror-imaging vortices converging to a point). Anyway, here's his take on EM wave propagation - http://www.softcom.net/users/greebo/em.htm See also his thesis on flowing-space gravity (link to 'Main Menu', then 'What is Gravity?') oc |
