Wrong. But what did you expect?Do you have a better answer?
Why the symmetrically travelling twin's clock is only observed to time jump by half amount than earth's clock, from the perspective of the first travelling twin?In the explanation by Henry's Minutephysics and Mahesh' Floatinghead Physics, acceleration of the observed clocks don't cause any time jump. Time jumps only occur when the observer is looking at far away clock while changing velocity.You missed the fact that the Earth clock is inertial between the two events of the 'jump' and the traveling clock is not, so its worldline is half the temporal length that it would have had had it been inertial between its two events.Where does the number "half" come from?
We know we are having a knowledge gap when we have a quantitative answer without knowing where it comes from.
Let's observe how S function progresses from 2 pi i down to 0.Now let's observe the inverse.
Where's the paradox?
In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more. This result appears puzzling because each twin sees the other twin as moving, and so, as a consequence of an incorrect[1][2] and naive[3][4] application of time dilation and the principle of relativity, each should paradoxically find the other to have aged less. However, this scenario can be resolved within the standard framework of special relativity: the travelling twin's trajectory involves two different inertial frames, one for the outbound journey and one for the inbound journey.[5] Another way of looking at it is to realize the travelling twin is undergoing acceleration, which makes them a non-inertial observer. In both views there is no symmetry between the spacetime paths of the twins. Therefore, the twin paradox is not actually a paradox in the sense of a logical contradiction. There is still debate as to the resolution of the twin paradox.Should we take acceleration into the equation?

What experiments/theory led to the conclusion that light impinging on a moving object at any arbitrary speed( <c) would always arrive at c?
