摘要
不管引力场是以引力子传递,还是以引起时空弯曲的引力波方式传播,现代物理学还没有发现引力场传播所必需的介质。引力场在目前已知的空间环境中传播速度的大小和方向是稳定的,而且是从产生或引起引力场的起始位置向周围传播,引力场的这种特性导致了最接近静止的参照系的发现,也导致了运动物体引力场的相对性原理。和静止时相比,物体运动时其周围的引力场强将产生变化,运动前方相应的引力场将变弱,对应等场强面将变密,而运动后方相应的引力场将变强,对应的等场强面将变稀。位于运动物体前方的其它物体感觉到与该物体的距离比实际距离要长,而位于该物体后方的其它物体感觉到与该物体的距离比实际距离要短。其它物体感觉到的运动物体的位置要滞后该物体的实际位置。只考虑太阳引力场而忽略其它因素时,可推算出地球绕太阳的运行轨迹实际上是圆形的,太阳不在轨迹圆心,轨迹圆心滞后太阳实际位置一定的距离。另外根据目前所测量到的数据还可推算出太阳及银河系在太空中的运行速度可达5000千米/秒级。
Whether gravitational field is transmitted by gravitons or by gravitational waves that cause the curvature of space-time, modern physics has not found the necessary medium for the propagation of gravitational field. The magnitude and direction of the velocity of gravitational field’ propagation are stable in space with gravitational field spreading around from the position where generated. All these characteristics lead to the discoveries of the reference system closest to absolute rest and the relativity principle of the gravitational field of moving objects. The gravitational field intensity around a moving object will change comparing with that around the object in static state. The corresponding gravitational field intensity in front of the moving object will become weaker and the surfaces of the equal field intensity will become denser, while behind, the opposite. The object in front of the moving object will feel farther away from the moving object than their actual distance, while feeling less away when behind. The position of a moving object perceived by other objects lags behind the actual position. When only considering the gravitational field of the sun with other factors ignored, it can be deduced that the earth’s orbit around the sun is actually circular with the sun not in the center of the orbit which lags behind the sun by a certain distance. Based on the data measured by scientists so far, it can be calculated that the Milky Way with the solar system moves at a speed of up to 5000 km/s in space.
