Puzzles of (quantum) gravity
- The effective, semiclassical theory of gravity has raised lots of fascinating questions, some old and some new:
- is gravity really just the dynamics of spacetime geometry?
- why do we live in a huge universe?
- what becomes of spacetime at shortest distances?
- is there a statistical explanation of black-hole entropy?
- is spacetime physics holographic?
- what is the nature of dark matter and dark energy { is it exotic matter, exotic gravity, or perhaps a mixture of both?
- in the end, do we modify gravity and relativity, or do we modify quantum mechanics, or perhaps both?
