If archaeoacoustics refers to intentional acoustic design then a cave doesn't qualify unlike, for example, the Temple of the Warriors at Chichen Itza. There a single hand-clap produces a quetzal chirp (from stairs) followed by the sound of a rattlesnake (from colonnade). Two Quetzalcoatl statues reside at the top of the steps.

Where do we come from? Well, it depends on who you ask. For example, an astrophysicist might say that the chemical components of our bodies were first forged in the nuclear fires of stars. On the other hand, an evolutionary biologist might look at the similarities between our DNA and that of other primates' and conclude we evolved from apes.

This approach suggests that the ramp corkscrewed up the outside of the pyramid, much the way a mountain road spirals upward. The corkscrew ramp does away with the need for a massive mile-long one and explains why no remains of such a r

I thought the spiral ramp theory has been ruled out because it blocked the sight lines nessecery to keep the pyramid "square"?

Thats a bit vague. Do you think the builders figured out on the fly or in advance?

Dark matter—the unseen 80 percent of the universe’s mass—doesn’t emit, absorb or reflect light. Astronomers know it exists only because it interacts with our slice of the ordinary universe through gravity. Hence the hunt for this missing mass has focused on so-called WIMPs—Weakly Interacting Massive Particles—which interact with each other as infrequently as they interact with normal matter.
