How do you measure distance if space itself is "flowing"? Hey good point! And how might this figure into the Pioneer anomaly? Remember that spacetime is non-Cartesian. Remember that "space-time" itself is the euphamism and surrogate for the spatial medium. When Uncle Albert kicked out the "aether", something had to substitute it. Thus the descriptive mathematical construct, the "schematic" became the surrogate for it. As spatial energy enters the vicinity of a Solar system, it begins to accelerate, its velocity increases, toward the Sun. As it gets near to a planet, it accelerates into the planet. It will reach the planet's "escape velocity" at the same time it reaches the planet's surface. When this gravitational energy reaches the Sun, by then it has accelerated to the Sun's escape velocity, 617.5 km/sec, at the time it enters the Sun's surface. At any time during this flow of gravitational energy, it's velocity will be equal to the escape velocity of the object it is accelerating toward at the altitude the energy happens to be at that time. E.g., at the distance of planet Saturn's orbit around the Sun, the escape velocity of the Sun is 13.6 km/sec. So when gravitational energy flows into the area of Saturn's orbit, the energy's speed has increased to 13.6 km/sec (give or take a little due to Saturn's elliptical orbit). You might wanta elaborate a bit more on this subject per those long, long discussions on it several y'ars ago. You raised the point on how the Solar flow at the orbits of the inner planets manages to slow down to the (lower) inflow velocity of the planet and not "collide" with the planet. Well, every planet has its own entrained flow field (EFF) which extends out many radii from the planet. The EFF is synonymous with its gravity well or gravitational field. The EFF is the 'reverse starburst' flow field which travels *with* the planet (thus is "entrained"). It mediates and buffers the larger Solar flow, bringing the inflow at the planet's surface down to that planet's median escape velocity (Earh's being 11.2 km/s). As a side note to this, 'member as to how the EFF also explains the Michelson Morley null result. MMX was designed to detect a lateral flow which of course was absent. MMX was blind to a vertical flow. The null result was entirely consistant with the *entrained* vertical flow and in fact would be expected. The EFF also explains stellar aberration (previously used to 'refute' existance of the "aether"). |
