Brian Greene: "If you're moving relative to somebody else, time for you slows down." https://m.youtube.com/watch?v=QnmnLmwBmfE

Actually special relativity predicts the opposite: If you're moving relative to somebody else, time for you SPEEDS UP. Einsteinians somewhat less dishonest than Brian Greene explain:

David Morin, Introduction to Classical Mechanics With Problems and Solutions, Chapter 11, p. 14: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. [...] For the entire outward and return parts of the trip, B does observe A's clock running slow..."

"The situation is that a man sets off in a rocket travelling at high speed away from Earth, whilst his twin brother stays on Earth. [...] ...the twin in the spaceship considers himself to be the stationary twin, and therefore as he looks back towards Earth he sees his brother ageing more slowly than himself."

Einsteinians have discovered that doublethink (believing and teaching both thesis and antithesis) not only destroys human rationality but makes the process irreversible - the affected person never restores his/her sanity. The slogan is: "Don't just repeat the lie - repudiate it from time to time. Victims get permanently paralyzed and Divine Albert's Divine Theory rules forever."
