The Big Bang is a big bust. It is man’s feeble attempt to explain he unexplainable. The universe is steady state and has always been there. The apparent speeding away of far off objects is simply due to a defect in the speed of light. The further away from us, the faster they seem to be going.
In graduate school, I worked in a lab using Salmonella for research. We were careful but every few months, someone would come down with a case of Salmonellosis for a few days. Makes sense to me!
