Twistors and Quantum Non-Locality
Speaker(s): Roger Penrose
Abstract: Space and time are two of the universe's most fundamental elements. Relativity combines these two into the unified notion of space-time, but twistor theory goes beyond this replacing both by something entirely different, where the basic elements are the paths taken by particles of light or other par... read more

Before the Big Bang: Is There Evidence For Something And If So, What?
Speaker(s): Roger Penrose
Abstract: There is now a great deal of evidence confirming the existence of a very hot and dense early stage of the universe. Much of this data comes from a detailed study of the cosmic microwave background (CMB) - radiation from the early universe that was most recently measured by NASA's WMAP satellite. But... read more

Clocks at the Big Bang? Quantum gravity is not what you think!
Speaker(s): Roger Penrose
Abstract: It has been a common viewpoint that the process of quantization ought to replace the singularities of classical general relativity by some chaotic-looking structure at the scale of the Planck length. In this talk I shall argue that whereas this is to be expected at black-hole singularities, Nature's... read more
