time has one direction (forward) because entropy (a measure of disorder) never decreases in a closed system such as the universe.

Thermodynamic entropy is not a measure of disorder.

At the beginning of the linked vid they were discussing a theory of Entropy as simultaneous creation and destruction (matter vs anti-matter) of the space between the nucleus and electrons of an atom.
The way it was pictured in my mind (I’m listening while reading FR so I don’t know what they were using as visuals) was that there is two simultaneous things existing in the same space and time, energy used to balance is slowly consumed which is Entropy.
I am not a Scientist I just love watching and listening to these shows and was a fan of Feynman back in the day.
