But I disagree with you that we cannot define our direction in time. Our direction in time is characterized by the fact that entropy is always on the rise. In a reverse-sequence version of our universe, entropy would always decrease, just like a video that's being played backwards.

In actuality I think that time runs in both directions at all times (time is arbitrary), but we only experience one direction. In this manner, we are constantly intersecting with reverse time at every instantaneous moment. Right now is happening forward and backward, so is right now, so is right now. The sequence, however, only happens in one direction, or at least we only experience it in one direction. But again, our sequence is always in reverse with respect to an opposite one, so yes you can't really define which is which. However, with respect to just one universe unto itself we say by default that entropy increases when time is running forward for that universe. It may be that conscious creatures only experience time that runs "forward."

Yes. And all this is without expecting other time dimensions, becausethe the level of freedom would be infinite.

But lets stick to the subject "light speed".
