@anorlunda those would be much more acute triangles than L4, but easier location to reach I suppose.

@Ibix SOHO was at the back of my mind while thinking of this. So change the question such that Craft C is at L4.

Well that makes it rather simple then. That is the problem with lay physics, little appreciation for the scale of things.

If a hypothetical spacecraft could keep station at the 2nd focus of Earth's orbit, what useful observations could be made? Each minute sees a new solar triangle Earth Sun Craft (ESC). Swept area remains constant, as should length SC, and length CE + ES. With the Sun as our point source...

It is certainly a very small effect if it exists at all. However it would be a potential source of error in some fairly popular observations. Mr. Simaciu attached his name to this, so I thought that might warrant at least a cursory look at the science in the paper rather than criticism of...

A quick search turned up Simaciu, Ion. (1997). Chromatic aberration of gravitational lens. 10.13140/2.1.1133.6003. The math is beyond me so I first made a basic assumption that chromatic aberration of gravitational lenses worked somewhat analogous to a prism in that red is bent less than other...

It doesn't matter if the distant observer is at rest relative to earth. All that needs to be known are the relative angles to the subject and the distance from the distant observer to the Earth observer at the time the shots are taken. That is, the distance between the point where the distant...

Redshift due to simultaneous contraction of all matter in the universe. There is a minor difference between the two descriptions that amounts to more than just a change of coordinates. What would be the result of this experiment. Equip a spacecraft , bound far from earth, with measurement...

Thank you bcrowell. It is hard to tell from your response where you would land in the poll. "Can a plausible model of redshift data be created without expanding universe?" It appears you would say yes, a plausible model is possible(or they already exist), but they will never produce any...

I do not have the solution referenced in the title, but I seriously ask if one could possibly exist. Given the observed redshift data, can there be a solution to any mathematical model which DOES NOT result in an expanding universe? Credit to user Chronos sig line: If a theory appears to...
