| 31. | Simone Speziale and collaborators have also applied twistor string theory to loop quantum gravity.
|
| 32. | This raised new hopes for the canonical quantum gravity programme.
|
| 33. | It could cure diseases, design starships, and express an exquisite theory of quantum gravity.
|
| 34. | The vacuum of quantum gravity treats gravitational effects not included in the Standard Model.
|
| 35. | Spin foam formulations of quantum gravity use different degrees of freedom and different Lagrangians.
|
| 36. | One of the deepest problems in modern physics is the problem of quantum gravity.
|
| 37. | Another of Deser's research interests is covariant quantum gravity.
|
| 38. | When we understand what to do with time in quantum gravity we'll have it done.
|
| 39. | Alternative theories are M-theory and loop quantum gravity ."
|
| 40. | The duality represents a major advance in our understanding of string theory and quantum gravity.
