##
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.
