Background that particles sit in

In summary, the conversation discusses the nature of the background in which particles exist. There is a debate over whether this background is spacetime or something else, such as a zero-point energy field. The theoretical physicists are trying to understand if particles are truly independent entities or just a manifestation of the background. Some suggest that a Theory of Everything should focus on describing the background rather than trying to create it from what emerges from it. There is also discussion about whether our current understanding of 4D spacetime is sufficient for a complete understanding of the universe.

What is the nature of the background that particles sit in ? Everyone says its space-time, but then its non local and all kinds of strange things seem to happen.

Even if we say they are fields and not particles (or even both), why is it that people think that particles sit in spacetime when they show characteristics that are clearly different from what normally happens in spacetime ?

Why do the theortical physicists look for a way to make particles appear in a background independant way such that particles will create the background, when we have no reason to believe that particles are not just a misunderstanding of energy resonating in a layer of reality we call spacetime ?

Is the background really spacetime ? If so, what evidence is there for that?

Particles sitting on spacetime seems up for challenge. Einsteins General theory suggests that particles are in fact part of the vacuum, making the vacuum a physical sheet. The background of spacetime is the zero-point energy field, a density energy making up all available energy in the universe.

I don't really understand "density energy". But if we take both spacetime and particles as being phenomena emerging from this "zero point vacuum" background, surely a Theory of Everything should describe the background rather than trying to create it out of what emerges from it ?

Or does anyone believe that our concept of 4D spacetime is the geometric totality on which a TOE will sit ?
 

1. What is the background that particles sit in?

The background that particles sit in refers to the environment or medium in which particles exist or are studied. This can include liquids, gases, or solids, and can also refer to the physical properties of the medium such as temperature, pressure, and concentration of other substances.

2. Why is the background important in particle studies?

The background plays a crucial role in particle studies as it can greatly influence the behavior and interactions of particles. For example, the properties of the background can affect the movement and stability of particles, as well as their ability to react with other substances or be detected by instruments.

3. How does the background affect particle size and shape?

The background can impact the size and shape of particles through processes such as diffusion, aggregation, and sedimentation. For instance, particles in a liquid background may have a tendency to clump together, resulting in larger and more irregular shapes, while those in a gas background may remain more dispersed and have a smaller size.

4. Can the background be controlled in particle experiments?

Yes, in many cases, the background can be controlled and manipulated in order to study the behavior of particles under specific conditions. This can be achieved through techniques such as adjusting the temperature or pressure, adding other substances to the background, or using specialized equipment to create a desired environment.

5. Is the background the same for all types of particles?

No, the background can vary greatly depending on the type of particles being studied. For instance, the background may be different for particles of different sizes, shapes, or compositions. Additionally, the background can also differ depending on the purpose of the study, such as in medical research versus environmental research.
