This may be a crazy idea, but it has occurred to me that human intention might have the power to reverse the second law of thermodynamics.
The second law of thermodynamics states, roughly speaking, that entropy (often thought of as the amount of disorder in a system) always tends to increase. It is one of the most fundamental laws in physics, and is generally considered to be inviolable.
But there are various reasons to think it might be less fundamental than is generally supposed. Entropy only increases over time because the Big Bang corresponds to a low-entropy state. Essentially this means that there are far less configurations of the universe that correspond to “Big Bang” conditions than to the conditions we find today. But this is only true to the extent that we have found a more precise way to describe “Big Bang” conditions than present-day conditions. By defining future states that we consider desirable, we are effectively defining a low-entropy state. If entropy increases only because we are moving away from the Big Bang, and because the Big Bang is the low-entropy state we have so far defined, then by deciding to aim for alternative, desirable, low-entropy future states, we may indeed be able to reverse the second law.
I have no idea whether this line of argument is either original or can be developed in a remotely robust way, but I thought I’d throw it out there anyway…
