Ether

In summary, the conversation discusses the concept of a place in the universe that is truly at rest with respect to everything else. The participants conclude that there is no such place and that the big bang occurred everywhere in the universe. They also discuss the cosmic background radiation as a possible absolute reference frame, but ultimately agree that defining one's position and velocity must be expressed relative to something else in the universe. The conversation also includes an analogy of living on the surface of a sphere to explain the lack of a central point in the universe.

If there was an ether it would absorb certain light frequencies, it is therefore possible to test if there is an ether or not with a wide spectrum frequencie generator.

Excuse me? The role of an ether was to embody radiation, to be the carrier of frequency theough its waves. How could it be an absorber too?

<h2>1.

1. What is meant by a place in the universe being "at rest"?

"At rest" in the context of the universe refers to a location that is not moving or experiencing any change in its position or velocity relative to the rest of the universe.

2. Can any place in the universe truly be at rest?

According to the principles of relativity, there is no absolute frame of reference in the universe. Therefore, there is no place that can be considered to be completely at rest. All objects and locations are constantly in motion relative to one another.

3. Is there a specific point in the universe that is considered to be at rest?

No, there is no specific point in the universe that can be considered to be at rest. The concept of rest is relative, and any point can only be considered at rest relative to another point or object.

4. How does the expansion of the universe affect the concept of a place being at rest?

The expansion of the universe means that all objects and locations are moving away from each other, making it impossible for any place to be truly at rest. Even if an object appears to be at rest in relation to its immediate surroundings, it is still moving due to the expansion of the universe.

5. Can objects within the universe be at rest relative to each other?

Yes, objects within the universe can be at rest relative to each other. This is known as a state of relative rest, meaning that the objects are not moving in relation to each other but are still in motion relative to the rest of the universe.
