THE SPACELIKE CURVES IN THE SCHWARZSCHILD FIELD AND SUPERLUMINAL EXPANSION OF EXTRAGALACTIC OBJECTS

Ⅰ. INTRODUCTION So far, no one thinks that the superluminal expansion of extragalactic object is a real motion with the super-light-speed, though eight objects with superluminal expansion have been observed. Many suggestions for the origin of the superluminal effect have been made. And an apparent speed faster than the light could be
