Document Summary

Universe started out much smaller than explained by standard bbt. It was so small it was uniform in temperature, then exponentially expanded. Much stronger than gravity (10 39 ) but acts only on charged particles. 100x stronger than em, but acts only on close range. Universe contained too much energy for its temperature: like liquid water under 0 c. Inflation predictions: homogeneity and isotropy of the univese, flatness of universe, few if any magnetic monopoles, distribution of matter over various size scales in the universe, the universe is .
