Michael Dennin

So I, you know, I have this other show that I do about pop culture sciences.

I mentioned Dr. Michael Dennin.

He does Ancient Aliens.

He's the skeptic physicist.

Sound is created by the vibration of an object, which causes the air surrounding it to vibrate and form a wave.

Michael Dennin, PhD, is a physicist at University of California, Irvine.

Depending on the frequency it oscillates with, that will determine the note or the tone you hear.

Hertz is the unit we use to measure frequency.
