New Cosmic Look May Cast Doubts On Big Bang

A new analysis of ‘cool’ spots in the cosmic microwave background may cast new doubts on a key piece of evidence supporting the big bang theory of how the universe was formed.

Two scientists at The University of Alabama in Huntsville (UAH) looked for but couldn’t find evidence of gravitational “lensing” where you might expect to find it, in the most distant light source in the universe — the cosmic microwave background.

Results of this research by Dr. Richard Lieu, a UAH physics professor, and Dr. Jonathan Mittaz, a UAH research associate, were published Monday in the “Astrophysical Journal.”

In the same paper, Albert Einstein’s 1917 theory that at a certain “critical” density the counteracting forces of gravity and expanding space can result in a “flat” universe no matter how irregular the distribution of matter might be, is proven mathematically for the first time.

Proving Einstein right might become a problem for the standard cosmological model of how the universe was formed because Einstein’s theory also predicts that the cosmic microwave background shouldn’t look the way it does, according to Lieu.
