Initially, a cosmic (not Einsteinian) conspiracy of the highest order made the speed of light gloriously constant:
Brian Greene: "If space and time did not behave this way, the speed of light would not be constant and would depend on the observer's state of motion. But it is constant; space and time do behave this way. Space and time adjust themselves in an exactly compensating manner so that observations of light's speed yield the same result, regardless of the observer's velocity." http://www.pbs.org/wgbh/nova/physics/special-relativity-nutshell.html
Neil deGrasse Tyson, Death by Black Hole: And Other Cosmic Quandaries, pp. 123-124: "If everyone, everywhere and at all times, is to measure the same speed for the beam from your imaginary spacecraft, a number of things have to happen. First of all, as the speed of your spacecraft increases, the length of everything - you, your measuring devices, your spacecraft - shortens in the direction of motion, as seen by everyone else. Furthermore, your own time slows down exactly enough so that when you haul out your newly shortened yardstick, you are guaranteed to be duped into measuring the same old constant value for the speed of light. What we have here is a COSMIC CONSPIRACY OF THE HIGHEST ORDER." https://www.amazon.com/Death-Black-Hole-Cosmic-Quandaries/dp/039335038X
Then cosmic magic became necessary. The traveling twin believes that, during the short turning-around period, a homogeneous gravitational field appears throughout all of the Universe. In this homogeneous gravitational field creatures age very fast. The further away from the traveling twin the creature is, the faster it ages. And that's what has happened to the stay-at-home twin. When the traveling twin returns, he sees that the homogeneous gravitational field from his dream actually did work - the stay-at-home twin is much older:

"For Adam to return back to Earth, he will eventually need to fire his rockets to turn around. When he fires his rockets, Adam will still continue to think that his spaceship is standing still. However, in order to believe that his spaceship is standing still, he needs to also believe that there is now a gravitational field present that is cancelling out the force from his rockets. Adam will believe that this gravitational field exists everywhere throughout all of space...Adam will believe that the gravitational field is causing time on Earth to flow much faster than time on his ship. It is only during this very brief moment when Adam is firing his rockets to turn around that he believes this external gravitational field is present...During the very brief moment when he fires his engines, he sees time on Earth flowing so extremely fast that this far more than compensates for the fact that he sees time on Earth flowing slowly during the rest of his journey. This is why Adam will believe that more time has passed for Sarah than for him when he returns."
