In scalar-tensor theories the gravitational sector is extended by including an additional scalar degree of freedom. The most general metric that can be built in such a theory includes disformal terms so that standard model fields move on a metric which is the sum of the space time metric and a tensor constructed from first derivatives of the scalar. In such a theory gravitational waves and...

109. Dark Matter, Dark Energy, Gravitational Waves and Black Holes

John Moffat (Perimeter Institute)

plenary

The standard model of cosmology features three key theoretical paradigms:

1) Inflation
2) Dark Matter
3) Dark Energy (accelerated expansion of the universe)

Inflation has severe fine-tuning problems and the need for eternal inflation and a multiverse. The alternative model Variable Speed of Light Cosmology (VSL) can avoid these problems and fit available observational data. The CMB is...

104. Predictions from the Quantum Multiverse

Laura Mersini-Houghton (University of North Carolina at Chapel Hill, USA)

plenary

In trying to understand the selection of the initial state of the universe, physics is experiencing a paradigm shift on the last decade. A multiverse extension of the standard model of cosmology is now a promising and active direction of research. I will provide a brief introduction of various efforts in extending cosmic inflation to a multiverse origin. I will then describe in some detail how...
