Hey everyone,

I need to understand the Wheeler-DeWitt equation. Basically that the universe is static.
I only have a foundation in special relativity and not general relativity as yet. Could you please recommend papers and books for this topic? Do I really need a thorough understanding of general relativity for this?

thanks
VVS

Dear VVS,

The Wheeler-DeWitt equation is a fundamental equation in theoretical physics that attempts to describe the entire universe as a single entity, rather than treating space and time as separate entities as in classical physics. It is a central concept in the field of quantum cosmology, which seeks to unify the principles of general relativity and quantum mechanics.

To understand the Wheeler-DeWitt equation, it is important to have a strong understanding of both general relativity and quantum mechanics. While a thorough understanding of general relativity is not necessary for grasping the concept of the Wheeler-DeWitt equation, it is important to have a basic understanding of the principles of general relativity in order to fully appreciate its implications.

Some recommended books for understanding the Wheeler-DeWitt equation and its implications include "Quantum Cosmology and the Wheeler-DeWitt Equation" by John A. Wheeler and "Quantum Cosmology: A Fundamental Description of the Universe" by Stephen Hawking. Additionally, "The Universe in a Nutshell" by Hawking provides a more accessible overview of the concepts involved.

I also recommend checking out some online resources, such as lectures and articles by leading physicists in the field, to supplement your understanding. It may also be helpful to consult with a physics professor or join a study group to discuss and clarify any questions you may have.

Best of luck in your studies.
 

1. What is the Wheeler-DeWitt equation?

The Wheeler-DeWitt equation is a fundamental equation in theoretical physics that attempts to combine the principles of general relativity and quantum mechanics into a single framework. It describes the behavior of the wave function of the universe and is used to study the nature of space and time.

2. Who developed the Wheeler-DeWitt equation?

The Wheeler-DeWitt equation was developed independently by theoretical physicists John Archibald Wheeler and Bryce Seligman DeWitt in the 1960s. They were both working on finding a way to incorporate the principles of general relativity and quantum mechanics into a single equation.

3. What is the significance of the Wheeler-DeWitt equation?

The Wheeler-DeWitt equation is significant because it is an attempt to unify two of the most important theories in physics - general relativity and quantum mechanics. It has also led to further developments in theoretical physics and our understanding of the fundamental laws of the universe.

4. How is the Wheeler-DeWitt equation used in research?

The Wheeler-DeWitt equation is used in a variety of research areas, including quantum cosmology, black hole thermodynamics, and string theory. It is also used to study the early universe and the nature of space and time. Researchers use the equation to make predictions and test theories about the fundamental workings of the universe.

5. What are some recommended papers and books to learn about the Wheeler-DeWitt equation?

Some recommended papers and books to learn about the Wheeler-DeWitt equation include "Quantum Gravity" by Carlo Rovelli, "Quantum Fields in Curved Space" by Birrell and Davies, and "Canonical Quantum Gravity: Fundamentals and Recent Developments" by Thomas Thiemann. Additionally, the original papers by Wheeler and DeWitt, titled "Geometrodynamics" and "Quantum Theory of Gravity. I. The Canonical Theory", are also highly recommended for those interested in studying the equation in depth.
