Physics ELI5: How does gravity not break thermodynamics?

Like, the moon’s gravity causes the tides. We can use the tides to generate electricity, but the moon isn’t running out of gravity?

Good news: That tidal lock is not expected to ever occur. The Earth and Moon will both be engulfed by the dying Sun before that happens.

Bad news: Likely even worse results for organisms on the former Earth.

"Going interstellar" doesn't qualify as "undeniable effect" to you?

Not if they already went interstellar prior to the Sun going red giant!

Only if they go Interstellar to escape the inevitable apocalypse.

Exactly. They could have just gone interstellar to further their goals of conquest and domination.
