I'm going to state that two inertial bodies that close distance on each other will (becouse of loss of simultaneity)observe time dilation. Also i will state that when one body accelerates it will actually time dilate from its frame of origin. So with this stated, if a rocket traveling under inertia toward earth at such a speed it can cover 100,000 light years in a year(in the rockets frame due to extreme length contraction) and the rocket could accelerate at such rate that it could come to rest with the earth in a distance of 1 meter. Then the observer on the ship would see the earth age >100,000 years over the distance of that meter correct. If so can anyone tell me what an observer on earth would see if looking at the ship?(adsbygoogle = window.adsbygoogle || []).push({});
