Although the "Big Bang" is often presented as if it is proven fact, there is a wealth of data, including recent revelations of the several space probes and findings in fundamental physics, which possibly tell a different story.
One of the first problems are found in the Large Scale Structures in the Universe. In recent years, there have been a number of very serious challenges to the current theory of cosmic evolution and the belief the universe began just 13.7 billion years ago. The existence of these "Superclusters", "Great Walls" and "Great Attractors" could have only come to be organized and situated in their present locations and to have achieved their current size in a universe which is at least 80 billion to 250 billion years in age. The largest superclusters ––- for example, the "Coma" ––- extend up to 100 Mpc!
In 1986, Brent Tully of the University of Hawaii reported detecting superclusters of galaxies 300 million light years (mly) long and 100 mly thick - stretching out about 300 mly across. At the speeds at which galaxies are supposed to be moving, it would require 80 billlion years to create such a huge complex of galaxies.
In 1989 a group led by John Huchra and Margaret J. Geller at the Harvard-Smithsonian Center for Astrophysics discovered "The Great Wall", a series of galaxies lined up and creating a "wall" of galaxies 500 million light years (mly) long, 200 mly wide, and 15 mly thick. This superstructure would have required at least 100 billion years to form.
