Fundamental cosmology and the galaxy distribution

John Peacock

Progressively larger galaxy surveys have helped to establish many of the ingredients of the current cosmological model. As a result, we can now be confident that the strength of gravity on Mpc scales is within 10% of its standard value, and that Dark Energy is close to a cosmological constant, evolving in density by no more than 10% since z=1. I will briefly review the latest evidence for these conclusions, and discuss the prospects for efforts to reduce these constraints to the 1% level over the next decade.
