The aim of this conference is to discuss key questions in early universe cosmology in the
light of the question as to whether time is fundamental or emergent, i.e. is time an
essential aspect of nature that must be a part of the fundamental description that governs
the universe at its earliest instants, or is time rather like temperature, an emergent
quantity that plays a role at the semiclassical or large scales but is inessential to the
fundamental description. These questions include whether the initial Big Bang
singularity was the first moment of time or a transition from a previous era, whether laws
of physics evolve, what is responsible for the arrows of time, and what determined the
choices of the laws and initial conditions. The plan is to bring together for critical and
focused discussions several of the most influential and provocative contemporary
thinkers on these questions. We hope to involve leaders with diverse views on the nature
of time. The workshop will be organized around focused discussions and debates, with a
few talks.
