questions about electromagnetic acceleration wiki page
« on: July 21, 2022, 10:20:33 PM »
The wiki page says that scientists have not thought of or proven that light might bend as it travels through space, they haven't even considered it.

1. In science class, they told me about refraction and reflection. Einstein's prediction that huge gravitation forces could bend light was famously observed 10 years after its publishing by multiple scientists. Does that count as having considered it?

The wiki page next says that scientists concluded RE because they assumed light travels in a straight line in a vacuum.

2. Does this mean that if light travels in straight line through a vacuum then RET is consistent with observations?

Next the wiki claims that light curves in celestial observations over long distances because the sky looks like a dome (maybe got this wrong, I found the writing unclear).

3. Are there any experiments, observations, or mathematics to confirm, describe, or quantify the curve other than the diagram of how the light curves to make sunset/sunrise on FE?

The wiki page seems to assume that the light bends however it needs to to make a sun high on the dome appear to rise and set on FE.

4. If the light is bending in unknown ways due to unknown forces without equations, how can we use any observation to know the shape of the earth?

The wiki page talks about the vertical component of the bending.

At noon in southern Egypt, it is dawn on the east coast of South America and sunset on the west coast of Australia. I have made a crude approximation of the problem in this image:

The white arrows are where the sun appears to be, while the red arrows point to where it really is in FET. Quite an amount of bend over what I make to be about 8000 miles. Also notice that the light does not bend horizontally when looking straight north or south. In fact the bend varies from 0 to more than 45 degrees as you move south, and when the distance is 4000 mi, the bend is zero. And it is symmetrical, bending opposite ways to east and west. Side note: RE distances and direction match FE along straight north/south longitude lines. Coincidence?

6. Does anyone have an explanation for this?

7. If this is due to acceleration, is that physical velocity or something else?

8. Same thing as Universal Acceleration, or two different simultaneous things?

9. What direction is the acceleration that accounts for both horizontal and vertical bending in the observed way it bends?

10. If light bends in due to unknown forces and unknown equations over long distances, how can we ever know where any far away thing is, or how the light bends, or how much, or anything, as seeing far away things is our only evidence and we can't rely on it being where it appears to be?
"Electromagnetic Acceleration" sounds so much more sciency than "bendy light".
