Key scientific Questions:
- Is gravity quantized, and what constitutes a quantum signature of gravity?
- Which observations cannot be explained using a classical theory of gravity, and which quantum aspects of gravity can we hope to test?
- Is there a separation of scales in gravitational interactions, or shall we expect ultraviolet effects to percolate to low energies?
- How does gravity (both classical and quantum) affect the dynamics of quantum systems?
- What is the relation between quantum reference frames in quantum mechanics and quantum observers in quantum gravity?
