In the space - time ripple - nipple the space and the time are related i.e. for every position in one coordinate system there is corresponding time. I believe that even statically the space - time ripple - nipple is affected by contraction and dilation. But how are space and time actually related? The only possible way of estimating the time that corresponds to one known position is using the speed of the light. From the origin we must send a beam toward the object’s position, wait for it to return and divide twice the distance with c. We can also knowing the time necessary for the beam to reach the object and get beck to the origin estimate it’s corresponding position. But implementing this method always puts the photon in the origin of the system. Mainly the motive for this post is the possible confusion when one atom emits “several” photons in different directions. Actually, we cannot view the phenomenon from the atom’s rest frame because only the photons might be at the origin of the system. The fanny thing here is that we have many photons so how do we know which one to be at the origin. The answer might only be all the photons. This is what we have to do: make as many copies of the atom at its current position as many photons are present in the system. Group i - th copy of the atom with i - th photon (i different from 1) and shift the group until its photon’s position becomes same as the first photon’s position. This way we will put all the photons in one place - the origin of the system and will get many copies of the atom on different positions. Also the emission of these several photons in the atom’s rest frame can be understood as emission of several copies of the atom in the photon’s rest frame. The idea of several copies of one atom is somehow hard to digest, but being equivalent, is the idea about several photons in one system also hard to digest?
