Abstract: NULL
Body: The unification of quantum mechanics and gravity implies that the notion of space-time cannot be fundamental, but must emerge from more primitive building blocks. Recently some remarkable clues for a new way of formulating physics without space-time have emerged, in the form of amazing hidden properties of scattering amplitudes in gauge theories and gravity. These developments have combined insights from string theory, integrable systems and twistor theory, and have exposed new connections between physics and and mathematics, in algebraic geometry, combinatorics and number theory. In this talk I will discuss the current status of this subject and describe possible future directions of research.
