If, as Paul Steinhardt claims, the inflation theory is truly untestable via scentific rigour, then it devolves into a belief system that requires an act of faith from its advocates. Not susceptible to intellectual investigation and can therefore have no place in science.

There are many universes but one universe has to have a SELF-CONSISTENT ORIGIN theory.

There are many universes but one universe has to have a SELF-CONSISTENT ORIGIN theory. What's YOUR NON-METAPHYSICAL LOGIC CONSISTENT theory Dear Professor Steinhardt? We can point out the flaws in MONALISA but can't draw it better either and hence don't publicly criticize it.

The bubbles made in the inflationary age are 10 to the ten to the thirty five. The measures to allow inflationary theory seem improbable.

Again inflationary model breaks down under examination.
