From the time we are born there is light, visible light and unless one has a lack of vision, that visible light is something we live with day by day throughout our lives... But what is Light? To answer this question, I am posting two separate videos... This is the first and is a fundamental delineation of "Light" by Patreon's Professor Dave... Then I will delve into other areas of Light, which are a little more comprehensive... Why do this? As we find out more and more about the Universe we are a minute part of, light is used as a standardized method of calculating distance on large scales and much much more... Let's first take a look at the fundamentals with Professor Dave...
I hope you enjoy it...

I apologize for my overly simplistic question. Thank you for the post, Sergeant Harkins. It was a good one.
When I was a kid I read One Two Three Infinity by George Gamow. He said the universe consisted of an invisible "substance" they called Ether.
They don't believe in ether anymore, apparently. Now we call it Space-Time.
But what is Space-Time?
The theory is that before the Big Bang there was a singularity - a particle billions of times smaller than a proton that contained all energy, space, time, and mass. Surrounding this particle was *not* space; it was a void. There was nothing there. You couldn't fly around in it. It didn't exist.
A little hard to comprehend, right?
Anyway I was wondering if the current theory of electromagnetism said that these so-called waves were taking place in the "thing" called Space-Time.
Do you know the latest theories about that?
Thanks!
Jon

SPC John Waisman - John, It appears as if you are bundling everything into one ball, which makes it extremely difficult to understand one part of our Universe and another... i.e.; Space-Time and the Electromagnetic Spectrum... I am going to post a short video on the Electromagnetic Spectrum and another on Space-Time. I am not an astrophysicist by any means, but I am sort of a Physics buff... I love this science!!!

Sgt Harkins: I'm sure I'm doing it wrong. I usually do! So, theoretically, according to me, electromagnetic waves cause oscillations in some kind of "Stuff," the same way sound creates oscillations in air. And the "Stuff" is probably Space-Time. Or I'm wrong again. I look forward to the video!
