How are space and time related in the space-time ripple-nipple phenomenon?

In summary, the conversation discussed the relationship between space and time, specifically in regards to the concept of space-time ripple-nipple. It was mentioned that the speed of light can be used to estimate the time that corresponds to a known position, and that the emission of multiple photons can be understood as emitting multiple copies of the atom in the photon's rest frame. Finally, the conversation touched on the possibility of seeing the same original photon in deep space, and the difficulty in measuring the distance to these photons.

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?

What is the chance that the photon we see looking into deep space on a cloudless night is the same original photon that started the journey billions of years ago?

At the younger age of the universe, When the radius is equal to 186,000 mi and assuming the observer is at the center, the chance of seeing the same photon is 2 seconds of time.

At radius 372,000 mi, the chance is 4 sec; at 558,000 mi, the chance is 6 sec., so on..

When the universe expands, the chance of seeing the same photon get less and less within the same time period.

The point is how do you measure the distance to those photon. The only thing you can be sure of is constant c. So you must send another photon from the origin and wait for it to back with the result.

It's not necessary to send another photon. Photon don't really interact with each other although interference patterns (can be seen with light of the same wavelength or frequency but out of phase) do arise. Photon interact with matter as describe in quantum electrodynamics (QED).

The constant c is used to measure distance in the astronomical sense of light-year.

What is space?

Space refers to the vast, three-dimensional expanse that contains all matter and energy in the universe. It is often described as being infinite, and it is constantly expanding.

What is a ripple?

A ripple is a small, wave-like disturbance that propagates through a medium, such as water or air. In space, ripples can also occur in the fabric of spacetime itself, due to the presence of massive objects.

What is time?

Time is a measure of the duration between events. It is often described as the fourth dimension, along with the three dimensions of space. In space, time can be affected by factors such as gravity and the speed of objects.

How are space and time related?

Space and time are intimately connected and cannot exist without each other. This is known as the spacetime continuum. According to Einstein's theory of relativity, massive objects can bend the fabric of spacetime, causing distortions in both space and time.

What is a nipple in space?

A nipple in space is a small, raised area on the surface of a planet or moon. It can be caused by geological processes, such as volcanic activity or impact craters. Some examples of nipples in space include the Mons Huygens on the moon Titan and the Olympus Mons on Mars.
