In the first instance, the number you are quoting represents 10 followed by 10,123 zeroes. It is a big number. But what you say you have quoted Penrose saying is that it would take forever to write out those zeros. Not the number as in 1, 2, 3 etc. To write out 10,123 zeroes would take about an hour and a half.First off it is 10x10^123 - start writing zeroes now. We will time you.
The very first sentence of this section is:
How special was the big bang? (perhaps the folks at SZ or Quora missed it)
Then:
This now tells us how precise the Creator’s aim must have been: namely to an accuracy of one part in 10^10^123.
He is looking at the probabilities of ending up with our universe if done randomly. The search space is so huge the Creator;s aim had to be very precise.
He goes on to say:
“The argument can be used to explain why the conditions happen to be just right for the existence of (intelligent) life on the earth at the present time. For if they were not just right, then we should not have found ourselves to be here now, but somewhere else, at some other appropriate time. This principle was used very effectively by Brandon Carter and Robert Dicke to resolve an issue that had puzzled physicists for a good many years. The issue concerned various striking numerical relations that are observed to hold between the physical constants (the gravitational constant, the mass of the proton, the age of the universe, etc.). A puzzling aspect of this was that some of the relations hold only at the present epoch in the earth’s history, so we appear, coincidentally, to be living at a very special time (give or take a few million years!). This was later explained, by Carter and Dicke, by the fact that this epoch coincided with the lifetime of what are called main-sequence stars, such as the sun. At any other epoch, so the argument ran, there would be no intelligent life around in order to measure the physical constants in question — so the coincidence had to hold, simply because there would be intelligent life around only at the particular time that the coincidence did hold!”
Now either one of the greatest mathematical physists wrong in what he wrote or has been misquoted. Either way, you seem not to understand
