"..the fact that we experience the flow of time right now means we're not in equilibrium."

Absolute nonsense. It will never, ever be the case that a conscious entity fails to experience the flow of time. Equilibrium, for a conscious being, is nothing more or less than a decomposing brain that has reached the point where it's a homogeneous puddle of ooze, which is capable of experiencing nothing.

Beyond the physical constraints on the ridiculous statement quoted above, there is the fact that the flow of time has nothing whatsoever to do with entropy. Reversing entropy is not equivalent with reversing time. It's equivalent with introducing energy and/or matter to a system.

The voice sounds like that of Sean Carroll, and he's made this claim (that time's arrow is a function of entropy) many times. But it's rubbish. Time is nothing more or less than a sequence of events. Entropy is the observation that absent an influx of energy, events always lead towards disorder. He's even made ridiculous statements about entropy being why we remember the past and not the future.

The very idea that the arrow of time needs and explanation is nothing but an artifact of our mathematical models of reality, which should never be confused with reality itself. The fact that you can slap a negative sign on a number representing time and do valid math with it does not indicate that in reality, the flow of time (the fact that the real-world analog of the time variable always increases) is something in need of special explanation.

#3 : Why not ,but don't we say “Impossible only means that you haven't found the solution yet.”.
What if equilibrium is also a state where/when you can experience everything and nothing at the same time, like perfect entropy. Ergo time doesn't need (can't?) to exist in this state of unity. We know that Time is just purely relative at our perception (the further we are from someone, the more the past we see but every one calls it present). Haven't you ever be in love with a place or someone, the perfect unity of mind and body and feel like the time goes faster, like you "lost" some time. If you have found unity with everything and everything has found unity with you, do you even need time to explain something ? :)

The perception of our reality changes over time, some few centuries ago people were thinking that the earth was flat and the center of the universe and were using their science to describe it :).

For the point of the video, we can also see the perfect entropy as everything in one point.

I can't be arsed with all this technical stuff today, life is to short, lets just say the answer to the question is 'Because it doesn't' have a nice coffee, possibly a biscuit, listen to some Bach and watch the flowers shrink O:)

#3 "Equilibrium, for a conscious being, is nothing more or less than a decomposing brain that has reached the point where it's a homogeneous puddle of ooze, which is capable of experiencing nothing."

This statement doesn't make sense. There's no conscious being in a decomposing brain, so saying 'for a conscious being' isn't coherent. Long before a brain has become homogeneous ooze there is no consciousness, and there would still be too much structure in the ooze to say it is in equilibrium as is meant in physics.

I seems that after the post of this video...snotr time either started flowing backward again or came to a complete screeching halt...:'(

I'll opt for some of that nice coffee you mentioned, possibly a biscuit, Bach, and shrinking flowers instead..:P
