Uh, Trump caused galactic warming is causing the rapid expansion. Just ask billy nye. :-)

So the farther in universe we look, the faster objects appear to be speeding away from each other. But the farther we look, the further back in time we’re looking as well. So does this mean the universe is actually slowing down as it ages - nearer objects are older and not moving apart as fast as distant objects (star/galaxies)?

My personal observations and measurements of the Hubble constant are closer to 77 km/sec/Mpc...

I ignore both Cepheids and red giants and focus entirely on pictures of Chelsea's dad and the expanding size and mass of her mother...

What if I told you our “constants” aren’t constant? Would your dogma force you to balk?

Dark Matter.

Everything in cosmetology can be explained by invoking Dark Matter.

It's the universal fudge-factor.

1. The Universe was smaller way back then.

2. Light was faster way back then................

If the Universe is expanding (Yes, I know it’s trying
to get away from Chuck Norris.) then the distance between
atomic particles must be increasing also...?

Probably harder to measure though.

that should follow, that if ‘space’ itself is expanding, the the ‘space’ between atomic particles is as well..............

So, the whole equation is based on the “fact” that they observed “how many”(?) red giants over the lifetime of the star and determined “when” in that life cycle they peak ( and they all peaked at the same age). The whole equation is based on some obscure assumption not observable by anyone, certainly not a population of RGs and not even one. ( they burn for how long again?)

None of your points answer my question.

On your second point, 2. Light was faster way back then................, would imply a medium exists which affects the speed of light which violates Einstein's long established relativity theory - no?

On your first point, 1. The Universe was smaller way back then. What if the universe was actually larger back then? What if instead of expanding, the universe is actually contracting, growing smaller at an ever increasing rate like expanding foam, but in reverse?

Einstein’s Speed of light limitation is good only within its frame of reference.

As the universe expands, the speed of light as observed from a great distance appears to slow down, but within that frame of reference the speed of light never changes..........

The Universe is a gigantic Black Hole. All galaxies are "falling" down the hole.

Galaxies "farther down" the hole are "falling" faster than us and appear to be receding from us.

Galaxies for which we are "farther" down are not "falling" as fast as we and also appear to be receding from us.

I wish I had the Math capability to examine this theory.

The “Big Bang” is the Event Horizon for this Black Hole.

If that was the case shouldn’t there be some galaxies
that appear to be stationary, ie falling at the same
rate as ourselves, unless once you enter a black hole
everything starts expanding again???

Signed Confused.

Ps. While this text appears to me here and now it’s
actually there and then to you. Quantum textual entanglement?

You have a point.

But remember, it is space that is expanding.

I tend to think of space as a giant balloon that is being blown up. If you are a particle near the center of that balloon you would hardly notice. But if you are closer to the balloon itself your wiggle room would be getting increasingly more comfortable.

It’s a 4/3 PI R3 thing. And although we are not likely to be at the center of the universe our ability to look at that universe is limited to something like 13.8 billion light years in any direction. That’s what we can see. And it is a sphere inside a much bigger universe.

Don’t use any of this to answer questions on your next physics test. It is simply my imagination going crazy with only a fact or two as backup.
