Brian Greene: The moving clock is slow, the stationary one is fast:

Is this ASYMMETRIC time dilation (fraudulently "deduced" by Einstein in 1905) a valid result in special relativity? No. It follows logically from Einstein's 1905 postulates that, if two clocks are in relative motion, either clock is slower than the other as judged from the other clock's system, or either clock is faster than the other as judged from the clock's own system (SYMMETRIC time dilation). Then why does Brian Greene abuse logic and teach the non sequitur? Because symmetric time dilation (the valid deduction) doesn't, but asymmetric time dilation (the non sequitur) does imply TIME TRAVEL INTO THE FUTURE - the miracle (idiocy) that converted Einstein into a deity:
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")."
