What is the current state of research in quantum gravity? @Dinesh The Carlip paper is quite nice because it gives a overview over most of the popular topics. Maybe he should ask for a similar but more up-to-date review paper... |

Course advice for someone interested in strings and mathematical physics I think this question should be on academia.stackexchange.com |

Is it really a particle? @Arnold "a unitary representation of the Poincare group, the local symmetry group of the universe" <-- i always thought it is a global symmetry group. Could someone clarify that? |

Are the principles of space-time homogeneity and Isotropy independent of one another? But if you ask if "isotropic everywhere" and "homogenous" are related. Then of course the first implies the second. If you can not access the book look at preposterousuniverse.com/grnotes Chapter 8. |

Are the principles of space-time homogeneity and Isotropy independent of one another? However I don't think you can have isotropy without homogeneity. <-- that is wrong. |

Space-time geometry and metric +1 fot the cylinder example. It is often ignored that the metric only tells you about the local geometry. |

Schrodinger's equation (explanation to non physicist) 6 paragraph: maybe you should add that the equation only holds if H is time-independent. |

What does AdS/CFT have to say about quantum gravity in our world? Could you maybe show how one can see the non-local behavior from black hole entropy? |

What is background independence and how important is it? For some of the problems with even defining what background-free should even mean see: math.ucr.edu/home/baez/background.html |
