A great 16 page paper in quantum cosmology

In summary, the conversation discusses a paper by Fotini Markopoulou and Lee Smolin titled "Holography in a quantum spacetime" which is considered a landmark eureka paper of 1999. It introduces a new concept in quantum gravity and is simpler compared to other papers on the topic. The conversation also mentions Lee Smolin's 2003 survey paper and praises it for its comprehensive overview of the topic. Both papers discuss finite dimensional Hilbert spaces and the absence of extra "rolled-up" spacetime dimensions. The conversation encourages others to read these papers and be a part of this new development in the field of quantum gravity.

This is only 16 pages and in PDF so easy to print out.
It is by Fotini Markopoulou and Lee Smolin and it is called
"Holography in a quantum spacetime"

I nominate it for the landmark eureka paper of 1999.

String theory and branes are on the run, loop quantum gravity is in. This paper is comparatively simple because it is at the beginning of something new.

The other shoe to this paper is Lee Smolin's quantum gravity 2003 survey paper----which however is 90 pages, so not as easy to print out. Baez was just praising this Smolin survey in his "recent finds" It is a wonderful comprehensive survey but it is in a way *based* on this short much simpler 1999 paper with Markopoulou.

All the Hilbert spaces are finite dimensional!

There are no extra "rolled-up" spacetime dimensions (unless somebody wants to have them-----they arent necessary)

Here is the URL for Smolin's 2003 survey

http://xxx.lanl.gov/abs/hep-th/0303185

which is called "How far are we from the quantum theory of gravity?"

Found what I've read in the 90 page paper reasonably persuasive but really got religion when I read the 16 page paper. believe it deserves to be considered a breakthrough of some kind.
check it out and get in at the ground floor of a new development

What have you found on this topic?
 

1. What is quantum cosmology?

Quantum cosmology is a branch of physics that aims to understand the origin, evolution, and structure of the universe using the principles of quantum mechanics.

2. Why is a 16 page paper considered "great" in quantum cosmology?

A 16 page paper in quantum cosmology is considered great because it is a concise and comprehensive analysis of a specific topic within the field. It requires a deep understanding of both quantum mechanics and cosmology, as well as the ability to present complex ideas and theories in a clear and organized manner.

3. What are some common topics covered in a 16 page paper in quantum cosmology?

Some common topics covered in a 16 page paper in quantum cosmology include the Big Bang theory, inflation, dark matter and dark energy, the multiverse theory, and the role of quantum fluctuations in the early universe.

4. How does quantum cosmology differ from classical cosmology?

Quantum cosmology differs from classical cosmology in that it takes into account the principles of quantum mechanics, which govern the behavior of particles at a subatomic level. This allows for a more complete and accurate understanding of the universe, particularly in the early stages of its evolution.

5. What are some potential implications of quantum cosmology?

Potential implications of quantum cosmology include a better understanding of the origin and evolution of the universe, the possibility of a multiverse, and potential explanations for phenomena such as dark matter and dark energy. It also has the potential to bridge the gap between quantum mechanics and gravity, which could lead to breakthroughs in our understanding of the fundamental laws of the universe.
