Expansion vs distance and time

I’m feeling left out… where do I fit in?…

You can be an independent observer on an undefined plane of existence...

Sounds complicated, I’ll try not to let you dow… *poof*

What is the oldest star in the milky way? It has to be less than 100,000 LY from us. What is it's red shift? Does it match other same age, far off stars?

We have never found a method of oscillation yet, which does not change with gravity. From pendulums to crystal oscillators to atomic clocks, they all change with gravity.

I think a rotational ticker for a clock, would solve our clock problem, and allow absolute time to be measured.

"I think a rotational ticker for a clock, would solve our clock problem, and allow absolute time to be measured."

Don't most mechanical clocks and watches use a rotational ticker? In fact, a pendulum is a rotational ticker.

The expansion of the universe refers to galaxies, on average, receding from each other. AFAIK individual galaxies are not expanding, so no reason why stars in the Milky Way would be moving away from Earth.

Also the expansion of the universe is on average. Our nearest galactic neighbour, Andromeda, is moving towards us, and will eventually collide. I don't know the estimated time frame, but long after humans have disappeared, and probably after the Sun has turned into a red giant, about 1 billion years.

If you prefer, but I would consider a pendulum an oscillation, as it changes direction plus two full stops plus the 2 accelerations.

A rotational ticker would have one constant direction and a constant angular velocity.

Only one variable is changing...the direction, and it's a constant change.

Compare that to an oscillation and all the changes that it goes thru. Almost any exterior force can change a back and forth motion.

This allows us to use 3 axis vibrations(oscillations) to measure motion and orientation of your smartphone. And to measure gravity gradients at great sensitivities.

An atomic clock uses a dipole vibration. Lifting and lowering an atomic clock, leads some to believe that they are measuring space-time.

However, a long vertical shaft along the gravity gradient, the rotation will not change with the gradient, like the oscillator does. It measures and detects absolute time. Anywhere.

I don't believe that space is related to time. We have quantified and inventoried everything for 1000s of years with numbers. Thus, it is we who has given everything a math relationship, not nature. The first thing we learn in math, is that the numbers themselves are related. Now, they have even given the emptiness of space mathematical properties.

These modern academic narratives and pronouncements mystify me.
