is Gravity the Opposite of Light - Neptune's Tired Light - Shining Things Should Have More Gravity Than Non-shiny Things

I don't know if I've been dumb enough to say this before, but I've just been for a long walk into and back out of town, a big circle... and you know how it is when you get walking, you get the rythm, and especially on a sunny day like today, the old brain gets to jogging along with the pace of the walk, thoughts turn to, "Why we're here and what's it all about," and it all comes to nought.
Well, just before that point when it usually 'all comes to nought', I thought about TIRED LIGHT. And formulated a Mind Experiment to test if light gets tired over time, and space.
You can't do a TIRED LIGHT experiment on Earth because every time you re-bound the light, hoping to keep it alive for a long time IT'S AGE RESETs.
The light's age is local to every reflection.
So, we need to think of the farthest thing we've been close up to and measure the light coming off it. Fresh light from a close-up position. Voyager 2, for example, passed by Neptune on August 25, 1989.
Surely, several massive telescopes were pointing at Neptune to measure the same light arriving at Earth some 5 hours later.
We know the relative speeds of Earth-Neptune and Voyager2-Neptune at the exact time of light gather at the respective locations so any doppler shift can be mathematically removed from the calculations.
I bet the light from Neptune from Earth comes out tirder i.e. MORE RED-SHIFTED than the light from Neptune to Voyager 2.
And the other aspect of this post, "Is gravity the opposite of light?" if a HC Unit is pulsing out little excesses that light fills in the gap of, there's a DIRECT RELATIONSHIP. Light means something has pulsed out a bit of space, we know this as gravity. For every excess of space energy from an HC Unit, there's an equal and opposite fall-in of THE UNIVERSE. But you can understand how there'd be a vast difference in these passing waves when one originates from a pin-prick (gravity) and one originates from the enormity of space (light).
This is why it's then possible to say that, "Things that shine, stars for example, should be HEAVIER than the sum total of their atoms."
Anyway, as you were.
