Technically, the story is quite simple. In 1905 Einstein advanced his false constant-speed-of-light postulate and deduced (invalidly, but this is irrelevant here) the conclusion "the clock moved from A to B lags behind the other which has remained at B":
Albert Einstein, ON THE ECTRODYNAMICS OF MOVING BODIES, 1905: "From this there ensues the following peculiar consequence. If at the points A and B of K there are stationary clocks which, viewed in the stationary system, are synchronous; and if the clock at A is moved with the velocity v along the line AB to B, then on its arrival at B the two clocks no longer synchronize, but the clock moved from A to B lags behind the other which has remained at B by tv^2/2c^2 (up to magnitudes of fourth and higher order), t being the time occupied in the journey from A to B."
However the innocently looking conclusion
"the clock moved from A to B lags behind the other which has remained at B"
has an incomparably idiotic implication. The slowness of the moving clock means that its (moving) owner can remain virtually unchanged while sixty million years are passing for the stationary system:
Thibault Damour: "The paradigm of the special relativistic upheaval of the usual concept of time is the twin paradox. Let us emphasize that this striking example of time dilation proves that time travel (towards the future) is possible. As a gedanken experiment (if we neglect practicalities such as the technology needed for reaching velocities comparable to the velocity of light, the cost of the fuel and the capacity of the traveller to sustain high accelerations), it shows that a sentient being can jump, "within a minute" (of his experienced time) arbitrarily far in the future, say sixty million years ahead, and see, and be part of, what (will) happen then on Earth. This is a clear way of realizing that the future "already exists" (as we can experience it "in a minute")."
Except for marginalized "science deniers", nobody would agree that jumping sixty million years ahead in the future within a minute is insane - after all, scientists have been believing in it for more than a century. This universal and everlasting belief is the proof that the madness of our civilization triggered by Einstein's 1905 falsehood is incurable and terminal. Even if Einstein's relativity is abandoned for some reason, the madness will remain.
