Abstract: (arXiv)
The idea of gravity as an 'emergent' phenomenon has gained popularity in recent years. I discuss some of the obstacles that any such model must overcome in order to agree with the observational underpinnings of general relativity.Note:
- 18 pages/ v2: added discussion of TDiff invariance, emergence of diffeomorphism invariance, and more references
