Thank you. Your comments have been noted.

I don't believe that I can say anything more without getting banned from this forum. Therefore, I will post nothing more on this thread. My thanks to those who tried to help me understand their methods.

Please consider a universe without curvature, at least to start. Wouldn't the expansion history of the potion of the universe through whixh the distant object traveled, be contained along the parh EM took from its source to rhe earth? And if gravitational fields are -conservative, wouldn't...

Obviously, an Earth observer will not know that a distant object has emitted a pulse of light until the pulse reaches the Earth and is observed there. There seems to be a method of calculating the relative speed of the light pulse with the Earth at the time the pulse was created. The method...

define :"The Initial relative velocity with the earth" as the relative speed, determined by an Earth observer, at the time of creation of an EM pulse by a distant object . The object creating the EM pulse must be at a distance at which Hubbell space expansion is occurring. Use a distance of...

This thread had been moved to relativity discussions because I am now asking how the speed of light relative to the Earth is affected when the source of the light is at a distance where Hubbell space expansion is c or near c. I am not interested in what an observer on either the Earth or the...

My OP questioned the average speed of EM separately for each direction between the Earth and the voyagers. In the ensuing discussions I mentioned Hubbel Expnsion which causes at a distance of about 13.77 Billion light years, the speed of EM transmitted from a object toward the Earth to become...

I agree that the Voyagers have not yet reached the distance at which the Dark Energy force would prevail over the combined attractive forces of Baryonic and Dark matter. I believe a discussion of what happens after that distance is exceeded should be the subject of another thread. Inthe...

phyzguy, Look again at post #5 in this thread.

phyzguy, of coarse a Doppler Effect doesn't change anything. It is just an indication that an EM source has either gained or lost energy during its travel from its source to an observer, or alternately the EM source has a non-zero motion relative to an observer. At a distance of about 14...

My interest is in the method used to determine the relative speed of NASA's Voyagers with the Earth. I have been led to believe that is accomplished by a EMR pulse generated on the Earth and directed to a Voyager. A transponder on the voyager retransmits a pulse with the received pulse...

No, I believe it does change by its amount of energy lost or gained as it moves through the sun's gravitational field. I believe the amount of speed change should be equal to the difference in the value of the escape velocity at any distance from the Sun and the value of the escape velocity at...

Is the average nonlocal speed of light the same for travel out from the Sun and travel back to the Sun over the distances the Voyagers are now located?

Mentz114 said When two particles become entangled their quantum state becomes a single state (immediately) . Any change to this state affects both members of the pair (immediately). QT tells us nothing about times for individual entangled particles. Also, if there was a delay, would the first...
