Time exists because things in the universe tend toward more disordered states, or increased entropy. That’s the only reason it exists. Every law of physics works both ways through time, except this one, which is really just basic probability. The odds are higher for disorder than order because there’s more ways a thing can be in disorder because, well, it’s disorderly. Time is pretty real — things die, get cold — but it’s fun to think of that fact as merely an implication. In any case, Minute Physics has us covered.Reach this writer at michaelb@motherboard.tv.
