The universe may have alway been infinitely large. Its just that 14.8 billion years it started expanding, first at inflationary rates, then a slower strain of 1

The universe may have alway been infinitely large. Its just that 14.8 billion years it started expanding, first at inflationary rates, then a slower strain of 10E-18 / second. Its a lot like looking at a number line. That is infinitely long in both directions. And if consider all real numbers, it is infinitely expandable.
