Argument for Holographic Principle

In summary, Susskind argues that 3d information is equivalent to 2d information, and that if the information isn't at the horizon, then there wouldn't be any projection. However, the idea doesn't explain what the original universe must have been, and Occam's razor doesn't look good for that.

So around 44:00, Susskind begins his argument.

He put a variety of items into a region of space, and the added a minimal shell of material surrounding the items, then squeezed that material to form a black hole around the item.

Then he said that the amount of original information cannot be more than the amount of information hidden in the black hole. The information in a black hole is tantamount to the information on it's surface.

It's a very interesting argument. But how does it rigorous connect to information being encoded on the cosmological horizon. We know that its not the event horizon of a black hole. We know that a shell wasn't surrounding far away, and then compressed into a black hole. So where's the connection besides the fact that they are both horizons?

All it shows is that 3d information is equivalent to 2d info. But if the info isn't at the horizon, then there wouldn't be any projection.

Data can be compressed.
However when you have it compressed in cannot be re-compressed.
If what we take to be reality was a virtual reality, it would not be possible to compress data in the Universe we know of.
We can compress data though, so real really is real.

So the most compressed data is the reality and anything else is extraneous and does not contribute?

Personally I believe that the universe we observe is what we observed it to be.
I mean so what?, if what we see is actually is a model of some other universe?
Occam's razor doesn't look good for that, and the idea does't explain what the original universe must have been,
before somebody did a 720p video of it.
 

1. What is the Holographic Principle?

The Holographic Principle is a theory in physics that suggests the information in a three-dimensional space can be encoded on a two-dimensional surface. This means that the entire universe can be thought of as a hologram, with all the information needed to describe it contained on a boundary surface.

2. How does the Holographic Principle relate to black holes?

The Holographic Principle was first proposed by physicist Leonard Susskind as a way to address the information paradox of black holes. According to the theory, the information that falls into a black hole is not destroyed, but rather encoded on the black hole's event horizon, or boundary surface.

3. What evidence supports the Holographic Principle?

There is currently no direct evidence for the Holographic Principle, but it is supported by various theories and calculations in physics, including string theory and black hole thermodynamics. Additionally, some experiments have shown that information can be encoded on a two-dimensional surface and still describe a three-dimensional space.

4. Are there any criticisms of the Holographic Principle?

Yes, there are some criticisms of the Holographic Principle. Some physicists argue that the theory is not well-defined and that it relies on certain assumptions that may not be true. Others suggest that the theory is not yet fully understood and may require further development.

5. How does the Holographic Principle impact our understanding of the universe?

The Holographic Principle challenges our traditional understanding of space and time and suggests that our perception of a three-dimensional universe may be an illusion. It also has implications for other areas of physics, such as quantum gravity and the nature of information. However, more research and evidence are needed to fully understand the implications of the Holographic Principle on our understanding of the universe.
