In regard to my earlier posts. Has anyone ever conducted the following experiment: collect data for E0, Sa and SBa type galaxies and check whether their average shape gets distorted according to their redshift? The more distant galaxies of the same type (the ones that recede faster from us due...
So, what you imply is that the type of symmetry I used in my experiment (corresponding to simple reflection) doesn't allow me to infer the relative speed of one of the probes in the reference frame of the other one by multiplication (x2).
Both measurements are experimental - one of them just uses the symmetry of the system to infer the relative velocity of the other object. For example I can't apply the wave equation after the wave function collapses - the wave equation is deterministic, but the collapse is governed by a...
Can't really see that - in 2 separate "universes": i) universe 1 consists only of experimenter 3 + probe 1; and ii) universe 2 consists of experimenter 3 + probe 2. In universe 1 both the experimenter and the probe from the viewpoint of their own reference frames will measure 0.75c. The same...
I believe after all these answers I should make my post more clear: it is about the measurements and what happens in the reference frame of observer 3 + probe 1 + probe 2. I intentionally designed the experiment to be symmetrical. So, each probe can measure their distance and the speed towards...
Thanks for the answer, but I don't really see the rationale behind it. This is my basic assumption - experimenter 3 sees them each traveling with a speed of 0.75c. Their closing velocity should obviously be greater than c. When does the velocity addition rule kicks in? When would (according to...
I am pretty familiar with the theories of special and general relativity. I know how to add velocities, I know the main postulates and the experimental confirmation. However, I thought of the following thought experiment:
There are 3 experimenters (at the same point in space), who adjust their...
