The Quantum Conspiracy: What Popularizers of QM Don't Want You to Know

What the lecturer is saying, in my opinion, that Einstein's theory of relativity, is directly blocking the existence of reverse time travel.  As Quantum Entanglement disregards the theory, which Einstein termed as "spooky" behavior.

Perhaps the theory is not correct or partially correct as it does not handle the spooky behavior.

To summarize in a simplistic loosely defined sentence, "Perhaps reverse or forward time travel is possible."

You gotta love science...
