Things like this keep me wondering if eventually we will reach a point where we are unable to distinguish theories about our own past due to lacking the energy necessary to experiment with those conditions thanks to entropy.

What does entropy have to do with anything?

Entropy = the inverse of available energy to do anything at all.

I'm pretty sure entropy isn't what's stopping us from probing high energy levels.

I don't like that definition.

I like to consider ∆S the result of a smoothing operation over energy differentials.

You can put work into a system to reestablish an energy differential. It just necessitates obtaining that other energy differential with which to do the work.

Physics isn't a popularity contest.

Yes, but that doesn't change the definition of entropy -- it just borrows energy from somewhere else.

That's true -- we're a long way from being limited by entropy in experimental physics.

"size differences are illusory"

So two things standing next to each other are the same size as one thing alone?

Damn hard to imagine. I would think "size" does not really "exist" but is a man made concept. And by its definition, two things next to each other form a "bigger" thing.

If the available energy is dispersed and chaotic, we won't be able to concentrate enough to perform the experiments? Though I doubt that'll be the case at any time while the human race is in existence...

(caveat: I know very little of real physics)
