The commonly accepted age of the universe is 13.7 billion years. I assume that assumes an inflationary epoch. Since inflation is in debate, what’s the age without it? And since expansion is accelerating, I assume expansion was slower 10 (or 20) billion years ago. Could it be infinitely old? (IE no bang?) Maybe Ned Wright’s calculator needs an inflation switch.
Another odd thing I notice is that discussions of inflation usually include an after size. Steinhardt’s Inflation Debate says the size after is a dime. Wikipedia says 100 million light years. Big difference. It seems odd to me to say a size since inflation requires a “flat shape”. Doesn’t that mean there’s no edge?
