Another advance made in understanding the formation of the Universe

 Computer models are only as accurate as the parameters which control their results. Once this was referred to as , "garbage in, garbage out". These days it is called Climate Change. Though, to be honest, that psuedo science could more rightly be designated by the similar phrase, "garbage in, gospel out".

Getting back to the topic of this post, it is amazing how much we don't yet know. Keeping an open and inquiring mind is the only way to live. Now, that is gospel.

The crash they witnessed is an early formation stage for the largest type of structure in the known universe, and the recent findings suggest that the process took significantly less time than computer models have suggested. In addition, the abundance of dusty star-forming areas in this collision raises questions about how galaxies evolve.

"How this assembly of galaxies got so big, so fast is a mystery," Tim Miller, a doctoral candidate at Yale University and lead author of one of the papers, said in the statement. "It wasn't built up gradually over billions of years, as astronomers might expect. This discovery provides a great opportunity to study how massive galaxies came together to build enormous galaxy clusters."
