There isn't a fixed one, other than as time increases, then the *total*
entropy of the universe increases.
Heat death is not the *lowering* of energy, it's the homogenizing of
energy. The only reason we can do anything at all (motors, chemistry,
biology) is that energy is more concentrated in some places than in
others. It's the controlled gating of that energy from concentrated
spots to less concentrated spots that results in work, heat flow,
I suppose it could be, but it doesn't seem to be, experimentally.
That's why we took note of energy as an interesting quantity that seems
to remain constant, and why we guessed that it is conserved.
It wasn't my high school teaching (or university, that matter)
that made me beleive that gravity (only) attracts. I don't know what
planet you are living on. But it (so far) seems to be an experimentally

The local universe is expanding at the speed of light, FAPP. It is
impossible for something to exceed (go faster than) the rate at which space
is being created. All things are involved in this expansion but are
'measured' locally without consulting the rate of change. It's called Time's
Imagine seeing the local universe from a position which saw all things
happening in the context of expansion; entropy as we consider it would not
Never mind the breaking glass returning to its original state metaphors. Way
too macro to be pertinent.
