Abstract: A search for galaxies at z≈7–8, roughly 700 million years from the Big Bang finds only one candidate galaxy at z≈7–8, where ten would be expected if there were no evolution in the galaxy population between z≈7 and z≈6. The simplest explanation is that the Universe is just too young to have built up many luminous galaxies at z≈7–8 by hierarchical merging of small galaxies.
