In holographic principle, the boundary is wrt which light cone?

In summary, the holographic principle states that the description of a volume of space is encoded on a light-like boundary, but it is unclear which position in the volume is being referred to. In a black hole, this is easily understood as the light from all positions inside cannot escape the event horizon. However, in other volumes, the light cones of different points may not be the same. This raises confusion about the intended boundary. A potential source for further understanding is searching for "daniel domert holographic filetype:pdf".

It is stated that in the holographic principle (e.g., in http://en.wikipedia.org/wiki/Holographic_principle) that the the description of a volume of space is encoded on a light-like boundary to the region. But with respect to which position in the volume? In a black hole, it is clear, because all the light from all the positions inside the black hole do not go beyond its event horizon. But in another volume, the light cone of point A inside the volume is not the same as the light cone of point B ≠ A inside the volume. So I do not quite understand the boundary meant here.
Thanks for any enlightenment.

1. What is the holographic principle?

The holographic principle is a theory in physics that suggests that all the information in a three-dimensional space can be encoded on a two-dimensional surface. This means that the entire universe, including gravity, can be described by a theory in two dimensions.

2. How does the holographic principle relate to light cones?

The holographic principle states that the boundary of a three-dimensional space is represented by a two-dimensional surface. This boundary is often described as a light cone, which is a geometric shape that represents the path of light moving through space and time.

3. What is meant by "boundary" in the holographic principle?

The "boundary" in the holographic principle refers to the limit or edge of a three-dimensional space. It is the point at which the information in the space can be fully encoded on a two-dimensional surface, according to the principle.

4. Is the boundary in the holographic principle fixed or dynamic?

The boundary in the holographic principle is considered to be dynamic. This means that it can change and evolve over time, as the universe itself changes and evolves. It is not a fixed or static boundary.

5. How does the holographic principle impact our understanding of the universe?

The holographic principle has the potential to greatly impact our understanding of the universe. It suggests that the laws of physics and the behavior of the universe can be described by a theory in two dimensions, rather than three. This could lead to new insights and discoveries in the field of physics and cosmology.
