Comments by "Taxtro" (@MrCmon113) on "Brian Cox explains why time travels in one direction - BBC" video.
It doesn't. The BBC clearly doesn't understand it themselves.

@CorsetGrace >and allow for many possible futures, high entropy That's a consequence of the conservation of microstate information. But if we accept that, the same thing is true for the past as well.

@AhsimNreiziev >required to increase over time , or, in other words, as time moves forward Over time, yes. By why forward? Should also hold if you move backwards.

@louisboafobosompem4789 It's simple, because you repeat stuff without comprehension. You seek to explain a distinguished direction of time, but to do so, you rely on intuitions about the progression of time. It's circular. The video doesn't explain why one direction in time is distinguished, it only explains what we mean with that. What we mean with time going forwards.

@knowledge5669 Why does that happen though? There is no obvious physical reason. It's intuitive, but the intuition relies on time. And the direction of time is what we seek to derive from entropy.

@zaphodbogdan33 If you're so smart maybe you can tell us why one direction time is distinguished even though the laws that govern the movement of particles do not distinguish between them and the second law of thermodynamics itself derives from the conservation of microstate information that's equally time-symmetric.

@jp9707 So far so good, but in the after-sandcastle-state we can find a set of microstates just as large as sandcastles. And for people concerned with this sort of heap forward time would be like that special heap assembling itself magically. And reversed time would be the special heap degrading into a generic sandcastle. Ultimately this notion of entropic time seems sort of subjective.

@lukeyy Your explanation of time relies on the very same notion of time you're trying to explain.

Time "slowing down" doesn't require a distinguished direction in time.
