let's say at different intervals (as measured on C): tC = 0, tA, tB and tC are 0 (A and B are at over 0.9c relative to C) tC = 10, tA, tB are 1 due to time dilation (A and B are still at over 0.9c relative to C) tC = 20 (A is at over 0.9c relative to B and C) tA = 2, tB = 11? tC = 30 (A and...

Yes, let's assume that the mothership is A and the scoutship is B. Now, if A and B are stationary, B will eventually have 2 accelerations: a positive and a negative one. And we said that due to those 2 accelerations, time on B will go slower. But what if we have now a point of reference (C -...

Interesting. My problem is how we determine who's accelerating and who's deaccelerating. Without any gravitation involved, then any acceleration or deacceleration will be felt the same way (pushing toward the spaceships walls in one direction or another). Intuitively the bigger objects are...

acceleration is the rate which something speeds up or slows down. But without a frame of reference who's accelerating? We can say that the spaceship does. But what if we consider the spaceship as point A and Earth as point B? At some moment in time, the distance beween A and B increases at a...

So, according to my understanding, if we leave Earth and travel close to speed of light and then come back we may have time dilation (there will be one year for us, but 10 years for the people on Earth). But how does this work as long as there is no frame of reference? Why can't we consider...
