Distance to Alpha Centauri

I calculated the following figures awhile ago out of curiousity. For an idea of distance between Sol and Alpha Centauri at scale, let both stars (being roughly the same size) be reduced to a pair of green peas, 1 centimeter each. Put one pea on a table and call it Sol. Put the other pea in your pocket and take it 360 miles in any direction. Put this other pea on a table and call it Alpha Centauri. The two peas now represent the equivalent distance at scale between the two stars

star to star distance: 4.25 ly = 40,207,980,000,000 km

solar diameter : 696,000 km = 69,600,000,000 cm (sun to pea ratio)

Divide the kilometric distance by the ratio to get 577 km or ~360 miles

The numbers are based on earth figures using parallax and other questionable tools. Still, Taygetans cite the distance of Sol to Pleaides at ~440lya which is also an earth figure

Yes, there is spectroscopic data, but that data is altered as the beam of light passes through space, causing a wavelength slip, and... spectrometers are notoriously inaccurate, especially humans ones, and they are only good at what is immediately in front of them. They forget to contemplate the fact that space is not a vacuum as they tell you but is a high vibrational fluid. It distorts the spectrometer readings.
The problem is that from Earth you can only see what you know you can see. Whether with telescopes or not, same thing, the only thing that differs is the interpretation of what you see. And they don't take into account the temporal slip either.
