We understand most things about it

> It's a perpetual energy source right in front of us,

No it's not. It's a good way to store energy but in no way is a source.

> and can barely offer a basic explanation as to what powers it

It's not something that has power. It's a consequence of entropy.

> It even impacts time itself

You sound surprised by this? Given relativity it would be more surprising if it didn't.

IMO you grossly overestimate the amount humans know about things.

Science is basically a stream of updated realizations that the previous "known" things were actually wrong.

I underestimate it and overestimate it.

Excuse me, I'm off to build a battery out of a bank of leaf springs.

In a classical mechanics sense - yes. But the waves were detected just couple years ago.

It's true we only recently have been able to built equipment sensitive enough to measure them.

However, they were predicted in 1916 as part of Einstein's Relativity work: https://en.wikipedia.org/wiki/Gravitational_wave
