Gravity as an emergent phenomenon

In summary, the conversation suggests various resources for reading material on emergent gravity, including lecture notes, Wikipedia articles, forum discussions, and a paper by Ted Jacobson.

Can anybody suggest good reading material, introduction or review articles on this subject?
(I read and studied Carroll GR lecture notes, so everything at this level or below would be great.)

thanks

Dopy me...
search EMERGENT GRAVITY right here in the forums...LOTs of discussions,
here is one:

https://www.physicsforums.com/showthread.php?t=474303&highlight=emergent+gravity

Eric Verlinde has some cool stuff too

Also consider spin networks: in these models picture a geodesic dome...analogous to some prior home designs...in the mathematical modesl, node points represent [space] volumes, edges (lines) represent [space] areas if I recall...what's the precise connection between space and gravity?? which comes first??

You might also consider Neil Turok and Paul Steinhardt's THE ENDLESS UNIVERSE where they discuss a cyclic universe where gravity powers brane kinetic energy...I forget what they have to say about the origins of each, if anything...
brief summary here:

This thread is now almost two mos old...but maybe somebody still cares...an interesting paper which was referenced here in the forums:

Thermodynamics of Spacetime:
The Einstein Equation of State
Ted Jacobson (1995, 9 pages)

1. What is "Gravity as an emergent phenomenon"?

"Gravity as an emergent phenomenon" is a concept in physics that suggests gravity is not a fundamental force, but rather emerges from the interactions of other fundamental forces such as electromagnetism and the strong and weak nuclear forces.

2. How does this concept differ from traditional theories about gravity?

Traditional theories view gravity as a fundamental force that is responsible for the attraction between objects with mass. However, the concept of "Gravity as an emergent phenomenon" suggests that gravity is not a fundamental force, but rather arises from the collective behavior of other forces.

3. What evidence supports the idea of gravity as an emergent phenomenon?

One key piece of evidence is the observation that gravity is significantly weaker than the other fundamental forces, which suggests that it may not be a fundamental force itself. Additionally, studies of black holes and the behavior of matter in extreme gravitational fields have provided further insights into the nature of gravity as an emergent phenomenon.

4. How does this concept impact our understanding of the universe?

If proven to be true, the concept of "Gravity as an emergent phenomenon" would significantly change our understanding of the universe and the laws that govern it. It would require a revision of our current theories and could potentially open up new avenues for scientific exploration.

5. What are the potential implications of this concept for future research and technology?

If we can better understand the emergence of gravity, it could lead to advancements in technologies such as space travel and gravitational wave detection. It could also potentially help us solve some of the mysteries of the universe, such as the nature of dark matter and dark energy.
