COSMOS

!!!THE SCIENCE MOMENT!!!:
It's a bandwidth: 1420, known as the Water Hole to Radio Astronomers. A place on the frequency where all the waves go quiet ... well, almost but not quite. There is the matter of...

1420MegaHertz!: The Bane and Intrigue of Radio Astronomy when the Wow! was discovered by Jerry R. Ehman on August 15, 1977. Jerry was working on the SETI Project for Ohio State University, as well as the advancement of science knowledge and humanity in general.

1420Mhz is the emission frequency of cold hydrogen gas where hydrogen's electrons transition between two closely spaced energy states as the atom absorbs energy from ambient radiation (collisions), causing the electron to jump from a lower energy state to a (slight but significant) higher energy state.*

*I'm semi quoting / paraphrasing from multiple sources, links below.

When the electron returns to the lower energy state it generates an Electro Magnetic (EM) wave of 1420Mhz.

Out of the random "noise" of cosmic radio frequencies, it is so constant, so measured, that the initial - and exuberant thought - was that we'd found a communication signal from an alien technology!

That didn't turn out to be the case but it was a brief but still thrilling moment that looks and sounds like this,

God Damn right you do!

And DON'T think I haven't been discussing this with scientists and science fans for decades because I have.

Take a deep dive into an ancient discussion at Science-Agogo.
