What Time Really Is… And Why It Only Moves One Way

Why does time only move forward? Every law of physics works equally well in reverse - and yet your coffee never unheats itself, broken eggs never reassemble, and you remember yesterday but never tomorrow. The answer to this contradiction is one of the most profound discoveries in all of science, and it reaches all the way back to the very first moment of the universe. In this calming long-form documentary, we explore the real physical nature of time - not the philosophical version, but the hard science. We cover why the fundamental equations of physics are perfectly symmetric in time, what entropy actually is at the level of atoms and probability, why Ludwig Boltzmann's statistical revolution changed everything we thought we knew about irreversibility, and how every arrow of time - psychological, causal, thermodynamic, cosmological - turns out to be the same arrow pointing in the same direction for the same reason. We also tackle the deepest question of all: why did the universe begin in such an extraordinarily low-entropy state that Roger Penrose calculated its probability as one in ten to the power of ten to the power of one hundred and twenty-three - a number so large it makes the total atoms in the observable universe look like nothing?
