Sample interview questions: How do you approach the problem of information loss in string theory?
Sample answer:
Approaching the Problem of Information Loss in String Theory
- Identify and Categorize Information Loss Mechanisms:
- Identify the specific scenarios where information loss is predicted, such as black hole evaporation and cosmological singularities.
-
Categorize the proposed solutions into two main types: unitary evolution and non-unitary evolution.
-
Explore Unitary Evolution Approaches:
- Examine proposals that preserve unitarity, such as string dualities and black hole complementarity.
-
Investigate mechanisms for recycling information, like the “firewall” near black hole horizons.
-
Evaluate Non-Unitary Evolution Alternatives:
- Explore proposals that allow for non-unitary evolution, such as the black hole information paradox firewall hypothesis.
-
Examine the implications of non-unitarity for the foundations of quantum mechanics and the nature of reality.
-
