Modeling the Formation of Structure in the Universe To evaluate new information, to see how it fits with the big bang, cosmologists increasingly turn to supercomputers. A Universe in Ferment Cosmology.
Cosmologists have plenty to think about lately.
Cosmology is in the news, with theorists and observers contending to make sense of it all. Detailed observations since the late 1980s show that galaxies are not evenly distributed in space, as previously believed, but clustered, with areas of high and low density. Through a two-pronged approach, modeling microwave radiation from space and modeling the evolution of matter itself , Bertschinger looks at how small irregularities at the start of the big bang could have led to the universe we see around us now. The early universe was quite smooth. No, they're not Easter Eggs.
