Ruth Durrer: General Relativity and Cosmology
Cosmology cannot really be formulated without General Relativity (GR). Only within the GR framework can we consider a consistent gravitating spacetime. After a historical perspective I will concentrate on a few ’pearls’ of present cosmological research like the cosmic microwave background (CMB), weak lensing and weak lensing of the CMB. I shall explain how planned high precision CMB polarisation experiments will be able to measure effects of frame dragging on cosmological scales.

A. Shadi TahvildarZadeh: General Relativity at the Atomic Scale
"To what extent can general relativity account for atomic structure of matter and for quantum effects?" This was a question asked by Einstein and Rosen in their famous paper of 1935 entitled "The Particle Problem in the General Theory of Relativity" (nowadays widely referred to as "the ER paper"). More recently, prominent physicists such as Freeman Dyson have cast doubt on the possibility, or even the wisdom of, combining general relativity with quantum mechanics. In this talk I will describe how our knowledge of general relativity can in fact help us gain new insight into the microscopic world of elementary particles and their quantum laws of motion. I will revisit Herman Weyl's socalled "singularity theory" of matter, and explain that the main obstacle on the path to a possible symbiosis of GR and QM is a wellknown classical problem, namely the infinities inherent in MaxwellLorentz electrodynamics of point charges. I will discuss a possible remedy to this problem, and report on the recent progress my colleague Michael Kiessling and I have made in this research project, which also involves some of our students and research associates.
Robert M. Wald: You Can't OverCharge or OverSpin a Black Hole
The KerrNewman solutions are the only stationary black hole solutions of the EinsteinMaxwell equations in 4dimensions. However, these solutions describe black holes only when the inequality \(M^2 \geq (J/M)^2 + Q^2\) is satisfied, where \(M\), \(J\), and \(Q\) are the mass, angular momentum, and charge of the black hole. Therefore, if an extremal or nearly extremal black hole can be made to absorb matter with sufficiently large angular momentum or charge as compared with its energy, one would obtain an apparent contradiction with cosmic censorship. Hubeny and others have made proposals as to how this might be done, but a proper analysis of this proposal requires a calculation of all second order effects on energy, including, in particular, effects arising from selfforce. We show in this work that when all of the second order effects are taken into account, no overcharging or overspinning of a black hole can occur, provided only that the nonelectromagnetic matter satisfies the null energy condition.
